2011 - 2016 How to VIN Unlock Salvage Yard GM Radio Reprogramming its EEPROM (Chevy Camaro & Cruze)
HTML-код
- Опубликовано: 2 авг 2024
- In this video we go over how GM has prevented dealers from unlocking used radios that have been owner installed. I show you a method to UNLOCK an used salvage yard Delphi / Panasonic radio showing LOCKED on the display for 2011 up thru 2016 (for 2016 only the Cruze Limited) modular designs as used in the Chevrolet Cruze, Chevrolet Camaro, and Buick Verano or Regal vehicles of GMs global A architecture design.
We will show the GM MDI scan tool with GDS2 cannot perform a VIN relearn, as in the past was possible with the Tech2, so instead we will unlock the radio by using an inexpensive CH341a EEPROM programmer to manually update the VIN stored inside the EEPROM directly. This method does NOT involve any soldering (for this particular radio part number), hacking, destruction, or damaging of the radio circuit board or its chip(s) and thus preserve 100% of the functionality as originally designed by GM - while still clearing the VIN Theftlock correctly. However, to perform the remedies in this video you need to have access to an EEPROM programmer capable of programming for a SOIC8 24C128 EEPROM (marked 4S128 by Panasonic).
NOTE: Some other modular radio models may have a circuit board design that is incompatible with in-circuit programming, and for these a test clip WILL NOT work. You will have to instead desolder and remove the EEPROM chip if you are having problems reading it in circuit (e.g., getting all 00s). I can only confirm this particular salvage Panasonic radio with GM part 22870782 will work in-circuit. Also note, you cannot swap radio modules across models, even with the same radio part number. That's because, for example, a Cruze has a different keypad module than a Camaro and they do no transmit the same button codes. So you have to have a radio module programmed for the keypad module you need for this to be a successful outcome.
I illustrate this procedure using a bench top test harness constructed out of a salvage 2012 Chevrolet Cruze Body Control Module (BCM). The video is an exact match for unlocking the radio on a 2011, 2012, 2013, 2014, 2015, or 2016 Chevrolet Cruze or Chevrolet Camaro with the newer modular radio head unit GM part 22870782 and BCM 13585674. But you have to salvage the radio from the same model car, due to the keypad differences the radios are not interchangeable across models. This video is NOT going to apply to older vehicle Theftlock style unlock code type radios, and is somewhat different than the previous generation radios too - I have other videos for both of those - check my channels playlist for other model years. I make no claims this videos approaches are applicable at all if you're working on modules newer than model year 2015.

2013 Malibu ECO, replaced with salvaged 2015 Malibu LTZ radio. different part number but process was exactly the same. YOU SIR, HAVE SAVED ME $170!!!! Thank you so much!
Great info, I desoldered the eeprom from my water damaged radio and soldered it into the replacement radio. Both eeprom chips were different manufacturers. Even different from the one in your video, but it worked. Radio is unlocked and all features work. Thanks !!
the same programmer worked to rewrite the vin in my 2011 cts radio with no modifications and it worked flawlessly! (after finding a driver for the programmer) took all of 20 seconds
This is an incredible solution and I was close to give up with my project, but you gave me the motivation to keep on going. I explain.
I own a 2012 Opel Astra J GTC with Navi900 radio. It is a Bosch unit and looks very similar to the one you open in this video. I found a crashed GTC with the Infinity SoundSystem option and the same Navi900 from the same year. I pulled off of the crashed car all the devices of the Infinity system and also all the wire harness to put them inside my car (a huge work to isolate individually which wire goes where and also with the help of the UK Astra forum and technical drawings they supplied). I took also the Navi900 from the crashed car because I know it is coded to work with the Infinity system, not mine. The locking point was this anti theft system that Opel's after sales doesn't want to work on, because it seems to be a mess to make a VCI request to GM Europe (at least this is what they say). I will follow your tutorial and write a feedback here when it's done👌
Wait, GM owns Opel?
Why would someone have to make request to GM Europe if u have opel car
It's really starting to piss me off that manufacturers are "Vin locking" certain modules and making it where you cannot simply go pull a BCM, ECM, PSCM, or EBCM from another vehicle and program to your yours. They essentially force you to go to the dealership and pay premium prices for OEM parts and then get shafted buy the service department to program them. I just got a quote of $450 for an EBCM on an Equinox and then $250 to program, but you can find 1000's of them in a Junkyard for less than $100 and being that I was a tech for GM.... it literally takes about 20 mins to program a module. Talk about Highway robbery.....
damn, i have so much information today, love it thanks for sharing , new subscriber.
Thank you master, really amazing video and I learned a lot, thanks for your efforts
Thank you DrShock, really amazing video👏
Great video! I installed an 8in display on my 14 Silverado, the radio works but not the screen.
I have a 2.0 hmi and have seen other people make it work. The only time my screen lights up is when the truck is in reverse
Nice information sir thanks to share .
Спасибо ОГРОМНОЕ! Всё получилось, оказывается всё очень просто
Very appreciative of this video!! Proves you can swap out a radio in a Global A vehicle. I am inspired now to do a radio swap in my wife's '16 Cruze (looking to swap in a radio that has an SXM tuner.) With that all said, are those settings you set in the EEPROM software (_24C128, etc.) usually the same for most GM radios' EEPROMs?
Thanks. The EEPROM size used in GM radios has been increasing thru the last 15 years, my oldest videos talk about the 24C08 (8KB storage) whereas in 2011 it moved to the 24C128 (128KB of storage). You could have more newer ones still using smaller size EEPROMs, and visa versa. If you're working on a radio I've not covered, to be sure you have to open them up and eyeball it though.
@@DrShock Thanks for the tips!
Hi Dr, Thanks for the great help,
I have a 2016 Chevy Impala Radio Part# 22924536,
Board only has 1 Soic 8 with number 3121 5077A
Do you know if that is a eeprom or the Vin is on the processor.
@@henryford4337 I haven't worked on that particular radio board, but it's going to be in the generation that uses an EEPROM chip. Some board designs from Delphi use an SOT23 device, rather than a SOIC8.
Thank you brother !
Thank you! This video helped me repair a customer’s 2011 traverse. Couple questions:
1… what programmer and software did you use to read in circuit? I used 2 different devices and softwares and both were able to partially read in circuit but with errors when verifying.
2… How were you able to determine which chip held the vin data?
Again, Thank you so much!. Subscribed!
Thanks. For (1), I believe there's a link in the description. I prefer a modified CH341A, though there are some board modules you just have to desolder the device to R/W it reliably. For (2), trial and error as every GM radio design is different. ;-)
Great video!!!
Your videos are very informative. I was able to unlock a salvage yard radio for my daughter's Cruze. I was wondering if the same thing is possible for the 2019 UConnect systems in Dodge/Ram products? Thanks in advance for your help.
Thanks, I'm not familiar with how Dodge/Chrysler handles locking of their radios. But this approach I've shown here is fairly common across all GM models.
excellent my friend
Great Great video thanks you
Thank you DrShock for this solution, my customer thanks you as well for getting their tunes back!
I have a 2012 chevy equinox that the cd player is malfunctioning. If I buy a used unit, is it possible to open my unit and switch out only the disc hardware without causing issues? Thanks for the time and effort you put into this video!!
Thanks. Yes, this is a common repair approach. Just be sure that the GM part number of the donor unit white sticker matches your original exactly.
Very informative. I'm wondering if the VIN is as easy to find in the EPROM code for a 2018 Cruze? I have the 7" display part#42554703. If you have any tips on resetting this radio please let me know.
Thanks,
Great video. If I just need to change the screen module, lock message will appear?
thanks!
The screen and keypad can be replaced without causing a VIN lock. Only the radio module does that. But be sure the screen is the same part as they may not all be interchangeable.
Do you know if this will work on newer radios? For example a 2021 chevy equinox. And if so how do I identify the eeprom? I see like 5 different chips that look like they could potentially be the eeprom. Also, where can I buy these eeprom tools and software ? Thank you. People like you who dig in and figure things out fricken rock
Thanks. There are a number of tools that can be used, I link what I use in the description of my videos (and I put a cross link in the upper right of this video to a detailed video on those tools mods). Some of the newer radios may employ more of a microcontroller memory approach than using an EEPROM. Also there may be different types of serial EEPROMs used, like a 3 pin for example rather than an 8. It's not economical to figure this out on such a newer radio, as the process is one of trial and error. I'd usually pick up a couple of units from a salvage yard for $10 and experiment knowing one might be rendered inoperable in the discovery process. A 2019 radio isn't going to go for $10. ;-)
Very good ❤❤
Very informative video. I am going to try and do this with a 2014 GMC Savana 3500 radio. I ordered the clip and programmer, but how do I know which is the eeprom chip I need? I see 2 different ones on the board. One says 15532 5333 and then one that says E5P02 PF36. The 15532 is the only one with the dot signifying pin one on a corner, the E5P02 is in the middle. So I am guessing it is the 15532. I see about 4 others, but they are 1/2 the size of these 2.
Thanks, unfortunately there isn't a one size fits all video for this (I have published several and they are all because of different radios having different chips with differing content over the years) as there were multiple radio suppliers and multiple board designs across GM vehicles. So I have to start from scratch so to speak with each radio board and use some trial and error to identify the correct chip. I would caution that such experimentation requires some experience with board level electronics as well, as there are can be several chips on the board that have the same packaging (same size and number of pins) but if you connect power to one that is not an EEPROM it can and will fry it. To further complicate it, some boards even use a different chip package (i.e., not 8 pins) for the EEPROM. I usually grab a salvage yard radio, or two, for initial experimentation, rather than experiment on the radio to be unlocked. I haven't worked on your trucks radio design yet to know the answer, so you might google around in forums to see if someone has already figured this out for the 2014 GMCs particular radio board first.
@@DrShock I would be willing to ship it to you and let you experiment on it and see if you can wipe the VIN. Let me know if you are interested in that, to add it to your arsenal of radio reprogramming.

VERY INTELLEGENT!!
Hello sir how do you bench test the older versions of GM navigation on a bench like part number 10377531 ? They do have a regular GM plug but with just power and ground they don’t power up like other GM radios. Appreciate it
I haven't dived into one of the nav units yet, but I would expect it to need close communication with the BCM to power up just like the one I've shown here.
The power button on a modern GM radio doesn't actually turn them on, it just starts a handshake with the BCM to send a message over the communication bus that its ok to power on. Part of that is to perform the VIN lock check and such of course.
Great video. Thank you.
I'm struggling though. 2013 Cruze with higher end radio screen connector is a little different with only 7 pins available and here is this light blue connector that both screen and radio have and I can't find any information about it + I can't seem to figure out how to connect all the wires together. Could you help?
The touch screen type radios, both navigation and MyLink, will definitely be quite different than the more common base radio I've shown here. Different wiring harness design, very difficult to retrofit if not factory equipped, and very different circuit board layout. I haven't yet gotten to researching either of these touch screen types.
@@DrShock
Thank you very much for your response.
In the video, you mention that you modified the programmer voltage. I notice you soldered in a terminal strip and put a jumpter on. Is that the voltage modification you were talking about?
That's the voltage part yes, but there's also a software part. That video is linked in the upper right of this one.
How much do you charge to do this service. Bought radio on ebay. Now it has the old vin in it .
2012 Chevy Sonic radio I think it's a smart radio I bought it from the junkyard I took it back but if I buy another one how many tools would I have to buy
Hello my friend from Greece and thank you for your very nice video. I would like to ask you that if i have problem with the BCM there is a possibility to my radio will be dead with black screen and no any chime's, like the reverse parking chime? I have checked all the fuse, inside and outside of the vehicle and i have disconnect the battery for atlast 7 hours. Olso i have tried to scan with a Bluetooth OBD but nothing, no any faults. If you have any sagetions to propose, i will be very happy to hear you.
If the symptoms are specific to the radio only, and nothing else odd is going on. AND if the radio is completely dead, no screen no sound. AND if neither the radio nor BCM has been recently replaced, then I would *not* suspect the BCM for such a situation.
The BCM is needed to send the radio a power on message over the cars internal wired network. But, if there were a problem with the BCM itself, I would expect more symptoms than just the radio as many messages to many modules travel this same functionality.
I would be looking for a radio wiring harness issue first, most likely on the wire that messages travel between modules, so I would pull the radio and examine the connectors going to it for any damage or corrosion for some length. A meter to check the power and ground pins while you're in there too. A check for corrosion, and cleaning of same, on the negative battery terminal as well would be on the list. If nothing found here, I'd look at swapping in a salvage yard radio as a test.
Such electrical problems are exceedingly difficult to diagnose, even in the shop viewing first hand. And next to impossible over a comment forum. But the above is where I would start looking.
@@DrShock Thank you for your answer my friend. I have check the power cord, yellow colour and the negative, black colour with my multimeter and i have 12volts there but nothing else of voltage except the wake up cord, i think who it's 5volts. Is that ok to can the radio and the screen to wake up? And something more , one time, before yesterday and one time before couple of weeks when I get the engine of the lights still on power and they gone of when i power on the ignition.
Still sounds like an electrical problem given the cranking example you just mentioned. The fastest way to eliminate the radio as being at fault, is to swap in another to test with. But if you've got multiple symptoms now (the engine cranking causing the dash lights to go out) it may be time to take it to a shop. Without a copy of the factory service manual schematics, spare parts to swap test with, and higher end scan tools this kind of problem may be very difficult to track down DIY.
@@DrShock Again i am thanking you very much for your time. I try to find another radio to test if that's the problem and if it needs to be unlocked now i know the how to. I wish the best for you my friend.
Great tutorial even though it’s well above my knowledge level…. I watched the full clip as I have a 2009 Cadillac CTS and after jump starting the car all the centre stack functions are dead. A diagnostic test suggests the radio is to blame… i live in UK so limited / no GM help available…I purchased from US a new unit but different serial number!…. Do you think the car will automatically load the VIN number to this unit…. I’m hoping it will…
Thanks. When you purchase a replacement radio you just have to confirm the seller has put it into a _virgin_ state so that you receive it in an unlocked condition. So that when it first connects it will learn your vehicles VIN automatically. If you just get an used one from someone not familiar with how to reset them to the virgin state, you'll have to go down the path I showed in the video to change the VIN to unlock it.
@@DrShock
Just one other thought as mine is a 2009 model….if I can find someone who has one and can use it! Is the GM tech2 diagnostic tool able to reset / alter the vin ?
Thanking you in advance for your knowledge and assistance.
The Tech2 used to be able to do this, but around 2008 or so GM removed this feature (VIN Relearn) from the firmware as part of their discouraging reuse of used modules including radios. There's no money in it for GM to support anything other than brand new replacement modules, or ACDelco remanufactured ones, so they just don't support used/salvage yard part recycling anymore.
What program did you use to program this radio i have everything already but I don’t own a computer I was trying to use a laptop but I have no idea what program to use
You can use any EEPROM chip programmer device and its included application that supports the 24C128 EEPROM device. That can be a CH341A black edition USB programmer, or a TL866II+ USB programmer, for example. But it doesn't matter the brand really, just as long as the device type are supported.
Guys, fyi an important thing to keep in mind is that besides making sure the radio head unit module part number matches, you also have to pull the salvage unit from the same model of car to avoid extra steps/work. For example, even though a Cruze can have the same radio part number as a Camaro, they have different keypad, or radio control, modules. And the calibration programming differs inside the radio because of that making them not swappable as is.
So match radio head unit part numbers, and match models as well. Cruze to Cruze, Camaro to Camaro, etc if you want to avoid an extra step doing SPS programming with www.acdelcotds.com. If you have the right radio part number, but it was from the wrong model car, you can get still the combo working after you unlock the VIN by doing an SPS calibration update, but that's extra time and cost.
This is very cool... Have you ever used this method to wipe the crash data from SRS modules in '06 & up vehicles? We've been sending them off for that and I suppose they're doing something similar... And, that's what I thought would happen when you wiped the VIN completely... I saved this vid so I can order these "tools"... The one where you were using the Arduino, I was hoping you were going to spit out a mathematical formula where the master code was derived from the scramble code but that didn't happen... I guess GM had a massive database or something tied to that recording, huh? Keep up the excellent tutorials!
@@raylramey Yes surprisingly no algorithm in the firmware of those old Theftlock TMS370 radios from before 2002, but rather just a database of codes written out as Delco Electronics manufactured the units.
I have my CH341A modified for the 5 volt. I have connected everything as you have shown, but I keep getting a
Error connecting CH341(-1) error, My clip is on correct, It is on the 09400464 chip, set up as IC I2C, 24cXX to _24C08 in the AsProgrammer, and suggestion to what I am doing wrong? Is this for a 2011 Silverado.
I am having the same issue, can't connect. I think I've got everything hooked up right. Did you ever get to the bottom of this?
Awesome Video. I currently have a 2012 Camaro and wanting to upgrade to the 2014-2015 radio with My Link. I am assuming this trick will work. Do you have a way to unlock the factory Navigation?
The circuit board of the MyLink radios is very different, but the concept is the same. Factory navigation ties the vehicles VIN to a national database so you cannot update them once removed from the original vehicle. But you can unlock and use them, just with downlevel maps. Though once again the navigation radios, which came out before MyLink, are yet another different circuit board design. So for both it's a matter of locating which chip is the EEPROM. Something I've not personally investigated yet, but it is on my summer projects list. ;-)
@@DrShock Thanks for the info. I may get one and see what I can figure out.
@@justinstatham6378 did you get yours finished?
Do you know how to unlock a 2015 Suburban Radio? I have a module that I'm hoping to upgrade it too but the second I attempt to plug it in. It locks haha. Was hoping you had done one of these before and would be able to help me out. I have pictures of the module incase you would like me to send it to ya.
If I’m upgrading my 2012 equinox touch screen to a 2014 MyLink radio so I can have apple car play and maps and other features. By removing the stored vin I’m the new radio, once in my vehicle it will learn my 2012’s Vin. But should I not take the XM receiver from my 2012’s original radio and install it in the 2014’s MyLink replacement radio? Just so it will have the same radio XM radio number as well as with GM and XM will still have the proper radio id associated with my vehicle correct?
Also if I want to upgrade to the Pioneer 8 speaker system I have to replace the 4 door speakers and the amplifier? The subwoofers are the same for the 6 and 8 speakers. I will only be missing the center dash speaker unless you know how to wire it in?
Last but not least. I installed GM factory heated leather power seats in my equinox. The floor harness from my vehicle and the one that the seats came out of are the same and the power seats work great. The wires connecting to the dash control for both vehicles are the same. I replaced the dash controls from my vehicle to the controls with the heated seat buttons. The drivers seat has the module that controls the heated seats and when I hook it to a snap on scanner I can hear them clicking on and off but the buttons won’t work. My vehicle even had the fuses in the heated seat spots. Do you think the dealer should be able to make them work through programming or somewhere in the dash harness am I missing some wires?
The dealership wants $99.95 to program my new stereo so you think they can program it to my vehicle using the mdi and sds or whatever it is or is the only way to do what you’ve done? And for $115.95 per hour they can try to program the heated seats. I just don’t know what to do.
Any input from you would be greatly appreciated. Would removing that chip and swapping them from one radio to another work as well? If not I will have to buy the stuff you use as well as the programming software

Since you're doing a non-factory mod here, you might have to find a blog post or video specific to what you're seeking to do here. Some obvious challenges you'll have to overcome:
- Your vehicle is too new to use a Tech2, so programming would require the MDI scan tool to perform.
- I would expect the wiring harnesses to be completely different between these two radio types/model years.
- The XM receiver design is not shared/not the same between those two different radio options/model years.
- The EEPROM contents for a MyLink radio is not shared/not the same as what is used in the regular radios
- The SPS2 programming is tied to your vehicles VIN. Your model year/model/VIN will not show supporting a MyLink radio option so there will be some hoops for the dealer to jump thru using GMs Techline Connect system, if its even possible.
- If the Pioneer speaker upgrade was available in your same 2012 model year, then that is likely to be something that can be configured with the radio using GDS2. If it was new to 2014, less likely the new amp could be programmed.
- If the heated seats module is the same part number as the one available in model year 2012, then the dealer should not have too much trouble doing that one. It will again not match your VIN as-built configuration in SPS2/Techline Connect but if the option at least existed for that same year it may be possible to do still.
Typically this sort of non-factory mod will be unsupportable with factory tooling. You typically have to seek out an aftermarket outfit that will manually reprogram the Mylink for this purpose.
Where do I download as programmer you use? Whatever I find takes me to some site that’s china something? Can you send me the link you have so I can just dive in and try to do this? Also does this need the 5v modification to the eeprom usb thing I bought that you use?
My 2012 equinox is identical to the 2014 I robbed all the parts off of. Wire harness’s and all. So the my link 2014 radio is identical to the one “base model with XM” I took out of my 2012. I just wanted the apple car play. The heated seats and pioneer stereo are the same in a 2012 and 2014. Every wire is the same. I also have the bcm out of the 2014 and the pioneer amplifier that plugs in the same as my original amp. If I take the 2014 stereo snd 2014 bcm and write my 2012’s vin to them both because they are already programmed with the options should that not work?
Thanks again. I appreciate these videos. I just wish I understood everything you are talking about lol
You'll find that download information in the description of the video I linked in this one. The video about the CH341a programmer modification for 5V (look in the upper right of this video for a circle with an _i_ icon from RUclips to tap). It depends on the CH341a programmer you buy, there are many Chinese variations that look almost identical, some already have 5V support, some don't. Ask the seller to be sure.
If you already had this same regular production option (RPO) in both the 2012 and the 2014, and it showed this same RPO code on the silver options sticker for both then you have a good chance of what you described working out just fine. The problems arise when folks attempt to add uplevel radios to base model vehicles. The BCM and associated wiring harness will not support the upgrade.
so i have a 2011 saab 9-5 and the radio is malfunctioning (no sound comes through speakers and display is wonky. i bought a 2012 chevy cruze radio (same part number) and plug n play did not work as it is vin locked. my idea is to solder out the original eeprom and put in onto the working radio. thanks for the video and tips, wish me luck
You can absolutely transfer the chip between radios to remove the VIN lock, as long as the Delphi, or Panasonic, part number on the label matches exactly (and that you do get the chip pin orientation exactly correct on the board). But you may run into the button layout problem described in the video description that can occur swapping between the Cruze and Camaro.
There is additional programming to deal with the difference in keypad button modules between the two car interior dash designs. I'm not sure if this is contained on a second chip elsewhere on the board, or within the same chip as the VIN. Love to hear back on how it went for you in this regard.
Hi DrShock, I updated the EEPROM chip with my vin. The mylink screen isnt turning on. Do I need to do the radio SPS MDI programming to get the screen to turn on? '14 radio going in a '10 camaro with an adapter harness.
This video is for a conventional radio, so the techniques may not entirely apply to a touch screen unit like a MyLink one. There may be more than one chip to address the VIN relearn, or additional programming required. I've not had to unlock a touchscreen unit yet, so can't really say.
Typically there are communication bus changes that would preclude a 2010 era vehicles BCM from communicating correctly with a 2014 era radio. So be sure the supplier of your adapter has tested/supports this combination.
@@DrShock Yea the wireharness is supposed to fix that leaving programming. I will give the MDI shot today. Thank you!
wow, awesome video, can you please send the link to the software that you're using? thanks
You can find that in the description for the video linked in the top right corner of this one about that EEPROM programmer.
I have a question, do you know why sometimes the sound will not work after unlocking and installing these radios mostly on a Chevy Cruze? Even the radio came out of the same year and same trim model?
There were multiple radio programming calibrations used even in the same year and models to account for different speaker options and the presence of optional external amplifier modules. The replacement radio part number needs to match exactly with the original radio, and be pulled from the same make, model, and year.
I would suspect this sort of problem could happen still when there is a mismatch in these options. The unlocked radio would have to be reprogrammed using GMs SPS to correct set the speaker / amplifier setup for those higher end sound packages. Once unlocked there shouldn't be a problem doing further reprogramming.
I've been wanting to replace the MyLink radio in my 14 Camaro with the factory CD player from the base but my Chevy dealer basically said no and gave me that printout explaining why. My question is I see people buying Camaro factory radios on eBay all the time and they seem to have no issues getting their dealer to flash them. Is it just that the dealer won't do it even though they really could?
The GM dealers tooling will not support a configuration not available from the factory for a particular make/model/year. As long as you could have ordered it, they should be able to apply a flash calibration to it using SPS. But that's for updating a radio that isn't already VIN locked.
As far as VIN unlocking a previously used radio - well as we saw in this video the GM GDS2 tooling has disabled the VIN relearn function in favor of having you buy a new radio from your local GM parts counter. A very _motivated_ dealer might get the SPS tooling to update the VIN indirectly while applying a new flash calibration, but only if that calibration wasn't already applied to the radio module. So a hit or miss approach that most dealers would prefer to not bother with I would expect.
As we saw in the video GM definitely sends notices to their dealers _not_ to support customer requests to reuse previously installed modules - radios or otherwise.
@@DrShock Thanks for the explanation. Makes sense. I realize I'm probably the only Camaro buyer who wanted that configuration on the SS.
Could we simply desolder the chip from the old radio and solder it to the new one? That way it would take the VIN with it to the replacement radio?
Yep, absolutely. I do believe I mentioned this in the video as _preferred_ way to go in fact.
I purchased the eeprom USB and clip that you linked for this job. Do you have a video on how to set up the eeprom tool for the job? All I got was an uncovered USB stick and a bunch of parts.
No, but this one might help ruclips.net/video/hPKckby54uA/видео.html
I made it to getting the ASProgrammer to read, but the chip is giving me all zeros. Is there any place I could get a copy of the save file you made?
I don't save these files once the repair is verified complete. But reading zeros still sounds like a communications problem. What EEPROM family? Remember that a 24XXX and a 25XXX go into different sides of the ZIF socket. And a 93XXX must have a pinout adapter to work.
You'd mentioned about removing the eeprom if issues with reading. I have removed the eeprom and still receiving locked up on reinstall. GM P/N 20918429. I have tried other tips but it still goes back to locked. Any thoughts on how to bypass this error even after the eeprom has been removed?
Removing the EEPROM is a hack that worked on older GM radios, but a number of the newer ones require it to be present now. Of course, it could just be you removed a different chip, not the EEPROM device. Did you verify that first?
When I mention removing the chip, it's to put it into an offline chip programmer. Some GM radio boards cannot have the chips modified while still soldered into the circuit. So to get around this, you have to remove the chip and program it off the board to remove the VIN lock. Then reinstall it onto the board.
what happens if you put pure zeros in a vin mugar, or how to write so that it fits any car
Some model years you can put 0xFF in there, and some you would use 0x00, and that will get it to a _virgin_ state like a new radio. When the BCM and radio handshake in that state, it learns the VIN for the first time like a brand new replacement radio. That's what is done during remanufacturing, for example. Can't recall which flavor this Cruze radio was. You might try both 0xFF and 0x00 and see which works for you there.
DrShock if you just take away that little eeprom chip will this work ?? Not programong it just taking it away?
That _hack_ used to work on older style radios from the early 2000s, but I'm not sure what it will cause on a more modern type like this. If you have the tools to desolder the chip from the board, just swap it with your original radio which will contain the learned VIN.
DrShock great video very informative, I have an issue with a refurb radio for my Camaro that I installed but the facia buttons don't correspond to the functions. The blue tooth for phone works and temp works and the radio works by using non corresponding buttons. I was told by the radio refurb that the radio needs to be reprogrammed so I went to the dealer to have it programmed and they say the radio can't be programmed ? The part number of the radio was correct when I pulled it out. Could this be from another model car or is it because it showed a vin number different from my car?
The Cruze and Camaro share the same base radio, but have different keypads. The keypad programming is assigned at manufacturing time. Don't believe this can be changed, but if it could it would only be thru an SPS calibration update.
There's some more info in the description but basically you have to do more than get the same radio part number. You have to get the same make/model donor as well. The only way to be sure is pull it yourself, I recommend an LKQ salvage yard if near you. They let you pull your own parts with your own tools.
@@DrShock Thank you!
I appreciate the video. Followed your instructions and was able to unlock a junkyard Radio with same part# to fit my 2013 camaro. the only thing is that some of the function buttons don't work properly. example:1- power button is now a seek function. 2- source button is the Radio ON/OFF. 3- Menu button don't work, can't access clock.
I had saved the original file from the oem radio and programed it into the donor, Still same issue.
Any suggestion would be greatly appreciated.
Thank you
The keypad module communicates over a local bus to the head unit module, and the display module, in the designs this video covers. Typically they are a matched and programmed system of particular GM part numbers (display module, keypad module, and radio module) for each vehicle model. So for example the keypad module from a Cruze like shown in the video, is not the same as the one in a Camaro, even though the radio head unit module may be.
I suspect in this case you pulled this radio from a non-Camaro? I haven't ran into this situation as I usually match the car model and module part number out of habit, so I may have avoided this situation without realizing it. Given your experience, I suspect that there may be some keypad configuration information stored in a different chip on the radio head unit modules main board controlling this, since you mentioned overwriting the salvage yard unit with your original radio head unit modules eeprom chip contents. GM certainly does not make it easy, with hurdles and road blocks all along the way.
@@DrShock I called junk yard, Head unit module came out of a chevy equinox. that explains the issues I am having. They are going to send me another one that came out of a camaro.
That's the easiest route. There is a way to correct it and make any of the correct head unit part numbers work, but it requires that you use the GM service programming system (SPS) and a GM MDI scan tool. Kinda like with radios that have optional amplifiers that when swapped have muffled sound, you have to program the configuration for the vehicle the radio is installed in. One of the configurations in this case is the keypad, or radio control, module that's plugged in so that the button functions match up to the buttons being pressed.
Sir, what do you think will happen if we remove this EEPROM completely or if we fix new clear one ?
If you remove the EEPROM from the board, you will lose some user settings functionality. You will also lose some scan tool functionality. When you write the VIN area, you can write 0x00 if you intend for it to be unlocked for a yet unknown VIN. You don't have to write the specific new VIN, though this is the typical case for a DIYer.
Hi DrShock! Greetings from Canada! Im just wondering is there any way how could I identify the eeprom chip from my chev equinox 2011 that comes with navigation? The radio is made by denzo
I haven’t worked on a Denso radio myself, but the process will be very similar to Delphi or Panasonic. What I can’t say is whether Denso might use a totally different chip that doesn’t have 8 pins for example. You might try mhhauto forum to see.
@@DrShock I have found 1 chip that differs from the other chip installed in the radio board it says on top line 0721 on second line it marks ST EZ032 when I tried google it gives no info about that chip. Would you mind give me your professional insight with that chip? Thanks a bunch...the local dealer im my area charged me $179 and did'nt even unlock my radio..it was a straight up robbery I was so mad at them for thier imcompetence bs...
It's unfortunate the dealer charged you for their incompetence. As I showed in this video, they have GM bulletins telling them they cannot unlock these radios even using SPS. Some places just don't RTFM. It's hard to say over a comment system whether that's the right chip. I did find a forum discussion around the 2016 and 2016 Equinox nav radios, you might look at the photos to see if the board is similar to your 2011 enough to confirm this chip you have identified is the right one first. Google "2017 Equinox, trouble with radio".
@@DrShock thanks a bunch! I will look into it right now!
@@stalkerudeful Any luck finding the EEPROM on the DENSO unit? I'm also trying to identify the chips on a denso.
Help please i just changed the radio of my Cruze with salvaged radio and same thing happened but i don't have this connector .. what if I swap the ic of both the radio will it work
Yep, *if* the two radios have the _exact_ same GM part number on their white labels you can just swap EEPROMs and be gtg. Be sure to take note of the pin 1 orientation on the board.
Do you know how to unclok on new gm car with pro code ior
I mean to use used radio
And program corect vin
Well that's the point of the video right, you have to edit the EEPROM directly as GM removed the VIN reprogramming from the scan tool in newer years (after 2010). You may be able to do it via SPS (Service Programming System) as long as the same calibration has not already been applied to the radio. That route requires a paid subscription to acdelcotds.com though so I didn't evaluate it. There are no codes anymore, those went away in 2003 when the RDS radios were introduced.
Good evening I have a brand new Cheverolet Express Van that was supposed to have XM, and didn’t I have acquired the XM Module says theftlock any help you could provide
If it's 2010 and earlier, I have other videos you can watch for how to do that.
Do you think that taking the EEPROM off of the original board and soldering it onto the replacement board will work in stead of reprograming it if you don't have the tools to reprogram it?
Yeah, that's actually what you have to do on a number of Delphi modules as the chips are not readable in-circuit usually. Just have to be sure that both modules part numbers match exactly, GM and Delphi.
@@DrShock Ok so i purchased a used radio for my 2013 camaro because my original one quit working and to get the replacement unlocked by a dealer is anywhere from $65 to $175 and no one can get me in sooner than 2 weeks, so the two radios are identical part numbers and options and the software and hardware dates are matching too. So in theory I should be able to take the EEPROM from my original radio and put it on the replacement radio correct as long as the EEPROM numbers are the same
That's right, as long as _both_ the GM part number on the white label _and_ the Delphi (or Panasonic as the supplier may be) part numbers are the same. The distinction I call out there is because sometimes the GM number stayed the same but the supplier changed something and their number differed, and then you run the risk that the board changed inside. I'd recommend ChipQuik if you haven't done alot of these surface mount EEPROM removals. It makes it go easy af. You can find it linked in some of my older radio video descriptions. Take a photo before you remove it, triple check pin one position.
@@DrShock how I can find out what audio system came stock with my truck and when I buy the truck it was missing the front screen and the radio reciver how can I get it to sync again?
Have you wiped an Eeprom off a 2013-2017 Traverse/Acadia/Enclave radio? I can't figure out which one is the correct one & what read type it is. I was hoping you could shine some light.
Not yet, unfortunately GM seems to have many different radio circuit boards even when they share similar faceplates. Makes each one a _project_ to figure out.
@@DrShock I found 4 different SOIC8 chips, but it seems they're all either VRs or Mosfets.
I have found at least one Delphi board that used an SOT23-3 package EEPROM. So you might check for that type as well.
@@DrShock I will keep looking for it. I will get back to you if I find it. Thanks man.
Any updates? I too have a 2016 Mylink and can’t see any EEPROM SOIC8 outside of the one on the little board attached to the CD player. I’ve read it, but it looks like all CD related info, nothing like a VIN, and it’s a 25C, lots of info.
Can the Techline Connect program unlock the audio VIN of the latest new cars?
Hit or miss for an _used_ radio module. Like I showed in the video, GM service bulletins say no, previously _used_ radio modules can no longer be unlocked using SPS2. But despite that warning for some models it still _does_ work via SPS2, but for some years it does not. If you have the SPS2 VIN slot available, I'd try that first. If it's a bust, I'd swap or edit the EEPROM itself as I've shown here (and in several other videos on different Delphi and Panasonic radio modules used by GM).
So I guess this wouldn’t work in a 2010 Camaro. Idek what year the stereo is I bought or if it’ll work on my 2010. The guy said it would we’ll see
Great video dear which website I get ac programmer
Thanks. Links are in the video description.
im thinking of adding a my link system and im sure i asked the same question on one of your other videos, but can this work for the mylink system?
Yeah, you asked about whether the standard PDI module was compatible with MyLink. The answer there was no, as the Bluetooth functionality is integrated with MyLink, unlike with the standard radio design. Here, the topic is VIN unlocking and yes this same _approach_ would apply to a MyLink radio, though the disassembly and internal board layout are completely different than shown. I'm not familiar with the eeprom location on a MyLink radio design, but it will be there somewhere.
@@DrShock then I'm expecting some looking around. Thanks for the info man.
My original software was deleted while drshock was installing the eeprom integrated by following your program throwing path. Can you help me with this?
Not really following what you're asking here.
Hello I have a 2011 chevy cruze lt and I got a used factory stereo from the junkyard same model iwas wondering how much you would charge to unlock my stereo I live in phoenix, AZ
I'm not a business or doing anything like that. Just sharing knowledge. If you don't have the tools to reprogram the chip, you could just physically transfer (unsolder/resolder) your original radios chip to the salvage yard radios circuit board and it would end up unlocked that route as well as long as the GM and Delphi part numbers are _exactly_ the same and it is from the same model year and model vehicle.
Thanks for the info but my original stereo fried.
Will it work with a Camaro 2010? or what options would you give me?
This type of procedure is very part number specific, and part numbers are model year specific. You'll need to verify you have this particular type of radio by part number. In the video description are also some other differences, even with the exact same radio part number, that occur in firmware between the Camaro and Cruze, etc due to difference keypads used.
Thanks for the instructions i follow the steps one by one and successfully unlock my Camaro 2010 radio kind of a similar screen and same head unit but I'm stuck by one issue
The radio fm xm work amazing but i lost the aux option and Bluetooth music streaming as well
The phone is connected successfully and paired but cannot play music as no way to switch to Bluetooth to start playing 😢
Any advice will appreciate that
Best regards bro
Was the replacement radio the exact same GM part number as the original one *AND* did it come from another Camaro? Many of these radios appear the same cosmetically, but their firmware programming differs. For example there is a radio part number shared between the Cruze and the Camaro, but they are not interchangeable because the Camaro and Cruze have different keypads on the center dash area to control the radio so are programmed with different calibrations by the factory. Asking because what you describe could be another such difference.
@DrShock yes boss from same car camaro and same part number really confused and don't know what to do
And dealership asking for 175$ for 1hour programming and other 150$ for second hour programming
The Bluetooth streaming, if factory, comes from a separate module that sits below the radio ahead of the center console. It has a cable that connects to the back of the main radio. This module also controls the USB AUX input. Are you sure you have that cable fully seated to the correct connector? To visualize this module, parts of this Chevy Cruze video might help as both vehicles use the same Bluetooth module - ruclips.net/video/j9_hlUp8V5k/видео.html
If everything is connected properly, then this sounds like a programming problem enabling that module (i.e., the old radio had the option enabled but the donor radio did not). Which is going to require access to an MDI scan tool.
@DrShock thanks for this information
But i do have it
I think i do need mdi programming
Thanks for your response i really appreciate 🙏🏼
can you unsolder e-prom out of original and re-solder in salvage unit
Yeah I mentioned this in the video, that rather than reprogramming you can swap the chips. Though you will need micro soldering equipment since these are surface mount devices.
Hey I don't know if your still looking at the old video comments or not. Any idea if you were to read the original gmc chip and write to replacement buick radio. Would the startup screen change to match the brand or is the startup screen locked in the cpu? Can't find a gmc acadia but have access to a buick enclave same I'd code.
The calibration (aka programming firmware in GM jargon) is what controls whether the radio looks for a Cruze, or Camaro, type of radio keypad for example. And it would be where the branding data (e.g., Chevrolet or Buick) resides. I do not believe it is written to this same chip as the VIN though.
When I encounter a situation where the same radio part number is used across multiple models, I first get it unlocked at the board level like I've shown here. After that, I then will write the latest calibration to the radio using a GM MDI scan tool and GMs Techline Connect SPS2 software. This process is tied to a particular VIN. Sometimes SPS2 updating can unlock the radio, but the newer the model year the less successful this has become as GM endeavours to block the reuse of used modules (as with the GM technical bulletins I showed in this video).
Ok picked up a Buick Enclave radio for my 14 Acadia. Pulled and soldered my SOP8 (15532) onto the Buick board. Swapped the board into my radio with my xm chip, faceplate and CD player. Board is identical on a hardware level.
Wasn't patient enough for programmer to arrive. It's still locked and has the Buick opening screen. Haven't decided if I should swap the emmc and cpu. Or just take it to a tech and pay them to tell me it's not the same radio and won't work.
Still being locked would point to that chip _not_ being the EEPROM that stored the VIN (given the same GM radio part number to one with a known EEPROM location). Without a programmer, you're not going to be able to verify the content prior if it's a new board where you are trying to figure out which one it is. Many radio boards have multiple devices in the 8-pin packaging. Some radio boards have more than one EEPROM, for example. Some also use 3-pin SOT23-5 chip for the VIN instead of an 8-pin SOP8 type.
Yea I've read up on all chips on this board. There is no eeprom on either board. 2014 Acadia code UGY. Just gunna take it to the dealer and have them hit it with a tech2. I've lost enough sleep on this diy repair. Thanks for the help.
Final Update. Well like a beaten Rocky I got back on the horse and solved it. The EEPROM was a bust. No such chip on the board. So took a new route. Did a little Tsb search. If your 13-14 Acadia, Traverse or Enclave radio is giving you and grief. Try Tsb PI0962E. Ci Senior.. Answer is set your language to Spanish. It's the dumbest thing I've ever seen. So stupid I couldn't make it up. Gunna got back to dealership that told me the radio was shot and quoted 2200 to get me the flash update.
Have you ever vin unlocked 2011 -13 Chevrolet caprice ppv radios via eeprom?
No, but it should be a similar setup to what I've shown here for the Cruze. The EEPROM will definitely be on a different circuit board though, and in a different location.
I noticed you do not program the checksum into the following 2 digits after the VIN I have found this leads to a short working life of the radio to the new vin this is on UK market version, have you experienced any issues ?
Nope, no come backs for years of doing this approach. But that doesn't mean it's not used different by other GM suppliers. In the USA we have Delphi and Panasonic and I only work on those two supplier products. In those USA radios this numeric value is nothing functional, just a checksum exclusively used by the scan tool when it does the initial VIN learn. It has to be present, but does not have to be updated.
@@DrShock We have The CD400 and 400Plus all other models do not even use the VIN as far as I know I have always recalculated the Xmodem 16 checksum possibly not necessary then I have used the FF approach and also FF'd the 4 checksum digits too this works and you find the checksum correct if you re-read the chip afterwards thnx for you speedy reply
Thanks, good to know about the crc16 algo there, I'll have to run a few VINs thru and see if its the same on the Delphis just out of curiosity. BTW I always thought those euro CD400 series radios could be unlocked over the k-line bus, no chip level work required. But maybe that's an older design.
Do you have links to the software and driver you installed?
If you mean the GDS2 software, you have to subscribe to that at www.acdelcotds.com. If you mean the CH341 programmer, check the description of that video I included as a RUclips card for the driver and programmer software application.
Can you send me some detailed pictures of the setup you have there I’m retro fitting a Chevy sonic radio with the same radio plug into my ford ranger
So far I got the power positive and the negative but the car is out side my house so I don’t mind ripping th bcm out of the car if it means the radio will work
I don't have this bench setup any longer as it was just used for the one radio repair. So just what you see in the video is all there is.
Do I need vin number to unlock gm radio cause I sold a radio to someone and they said they need the vin number
You only need the VIN for the vehicle the radio is being installed in to unlock it. Folks may need to know the VIN of the donor vehicle to confirm the radio a compatible model to their vehicle though.
I have a question, if I bought a 2012 equinox salvage radio and want to put it in a 2012 equinox and don't have the program or programmers, can I unsolder the EEPROMs and swap them? Will that work as long as the radios are the same part#?? Thanks for all the info BTW. I've been going nuts trying to figure this out with no help from dealerships. They tell me they don't make the radio any longer and can't unlock a salvage radio so I guess they just expect you to live with it. That's just unacceptable for me.
Absolutely, you can swap the EEPROM chips to deal with this situation. There are many different radio circuit boards though, so the videos I've done may not cover what you have leaving the challenge of identifying which chip is the EEPROM one.
In this approach, what is absolutely critical is to insure that (A) the part numbers from GM and their supplier (e.g., Delphi) on the radio white label match exactly. Just the part numbers, obviously serial numbers and dates and such won't match. But part numbers must match. And (B) pull the radio from the exact same year make and model. This is necessary because GM sometimes used the same radio part number in multiple vehicles, but programmed them differently and that coding is not necessarily contained in the EEPROM chip that has the VIN. So you want to avoid that, such as code that handles different push button modules for the radio.
@@DrShock thank you so much for all the help. The 2 radios are both from the same year make and model Equinox and have the same white label part #. I will pull the radio apart tonight and see what I discover and may ask for some assistance if anything looks off. Thanks again 👍
Turns out working on a circuit board is not as easy as it looks lol. I am having a hell of a time getting the original eeprom off the board. Do you have any suggestions of who could reprogram the vin into the salvage radio eeprom? I live in Oakland county Michigan. Or maybe someone I could mail the board to such as yourself ?? Don't know how much it would cost but I'm very frustrated and no help from any dealerships. Maybe you could shoot me a price to do it, or point me in the right direction? Any help would be greatly appreciated. I just don't have the knowledge or understanding of programming to do this myself.
@@crazygrady127 Typically you would go the route I've shared in this video if you wanted to save $$$ and had the background in electronics. It's definitely not the average DIY area, but more an intersection between someone who's into the electronics hobby, but now needs to do this sort of automotive radio repair. For those with the background, it can be very rewarding to DIY this.
Another reason for my sharing this knowledge, is as you encountered, the GM dealerships have *zero* interest in dealing with used parts and discontinued vehicle models. This is mostly because of what all can go wrong on an older vehicle electronics job, and the lack of parts in many instances if they break or damage anything. GM has also inserted many barriers to reprogramming used modules over SPS, like a radio. So it's just not worth the dealerships time when that is all added up. Many independent repair shops will feel the same way about this sort of repair too, as if anything goes awry in a re-programming job it can burn hours and hours of their time when they could otherwise do several more profitable jobs in the same time.
My advice to folks who do not have the electronics background is to buy the radio off eBay pre-programmed (or VIN zero'd out). You still need to insure the radio is the exact same part number, and you need to insure it came from the exact same year make and model to avoid push button panel incompatibilities. You do not save as much money, but it's still cheaper than a new GM radio and having that programmed. And often less drama and unwanted side effects of installing a non-GM aftermarket radio to keep the vehicle all original.
@@DrShock Thanks again for all your help. It's greatly appreciated.
You said you needed to modify the eProm reader writer could you elaborate on that it would maybe send me a schematic
Checkout the other video linked in the upper right of this one, that is where the mod for his particular USB programmer is covered. If you don't use that particular make and model programmer, you may not need to be concerned with it.
I have a question. I have the original radio unit (A11) but doesnt power on. I recently purchased a used unit which is locked. Can the EEPROM be desoldered from the original and soldered into the donor radio?
Yep, if both radios have exactly the same part number _and_ came out of the same make and model vehicle. GM used the same radio part number in multiple vehicles, but programmed different keypad firmware on it. So you cannot, for example mix a Cruze radio with a Camaro since they have different keypad modules. You have to use Cruze with Cruze, or Camaro with Camaro.
Ok well my radio units are not same p n but rpo codes are. I believe the difference is xm satellite. Mine is a 14 Malibu LS and donor is a 13 Malibu LS so ive successfully desoldered the EEPROM from original non functioning radio. I believe i will try this and hope for the best. If i have to purchase another radio w same p n then nothing lost. Thanks for your help and will repost if this works.
Yes!!! It worked! It really worked even though the part numbers werent the same. Im guessing because the keypads are identical for XM and non XM. It just says no signal when I go to XM. And the best part is going to be when I call the dealer monday morning and cancel my service appointment to get radio unlocked! Thank you so much for showing me this.
This process is a bit laborious, I have a 2020 and my radio is damaged. I want to change it for the same one. It would be better to change the chip from the old radio to the new one. thank you.
I already pointed this out as an option in the video, if you have two radios then you can go the route of swapping the chips directly. If you don't have two radios, then that's not an option on the table. No short cuts on the radio disassembly though, required for either route to gain PCB access.
I have a 2011 Buick Regal and wanted to see if you know what chip or the chip number that would be the one that has the VIN #.
I'm not specifically familiar with that radio. But if you give me the GM part number on the white label, I can see if I have any info on it.
I did take the stereo apart and the salvaged stereo had 4 8 prong EEPROM chips
2 on the bottom where in position R760 and IC206 and it is - 0721 ST EZ 944
1 on bottom position C668 TJA 1040 82 09 n6942
And 1 on top ISSI 941 41283GL A3 in position IC601
It is a Panasonic
GM P/N 20907419
RPO U2K + UYE
class 1 Laser Product
Unfortunately I haven't come across this part number before, so don't have any info on it from a previous repair/unlock. But of the four likely 8-pin candidates you described, I personally would start with attempting a read of the device in position IC601. The reason being that number you wrote is very close to an EEPROM part number from ISSI (ISSI IS24C128-3GLA3). Read it as a generic 24C128 2-wire serial protocol device if your software does not have an entry for an ISSI. Look up the datasheet if you need to verify pin 1 so you power it in the correct orientation.
*Note that this is a best/educated guess and you would be attempting this with the possibility that the device is not as presumed, and could be damaged if its actual power and ground pins are not the same as an IS24C128-3GLA3.* So I would desolder it from the board soas to limit the damage. This is my usual approach when attempting to discover the VIN location for the first time on a new radio model. I usually buy _a couple_ of salvage yard radios for such experimentation casualties. ;-)
Thank you. Will pull the IC601 out and read it. Thank you again.
I clicked your eBay link for the Pomona clip and one is 15.99 and the other is 35.99, any difference?
I use Amazon for a part like this. But if you use eBay just ask that the seller assert via eBay message that the part is sealed in the _genuine Pomona Made in USA package_ or it's likely a fake. The Chinese are quickly figuring out to just make their black clips blue with the Pomona name on the side sigh.
Can I do the same with the ecm on a cruze?
Not sure what you're asking, the PCM on a Cruze is not VIN locked. Only the radio. You have to reflash a replacement PCM using a GM MDI scan tool (or equivalent), as there's not just VIN information but also theft deterrent information that has to be recoded.
can you remove the theft locked from a 2011 escalade stereo
You should be able to, but it's unlikely to be the same radio as this one shown here for the Cruze. You may want to take a look at the other videos in my library and see if there's another more similar to the one used by Cadillac in 2011.
Can I just simply swap the chips if it’s Camaro to Camaro? One was 2012 and the other is 2014/2015.
I haven't personally tried mixing model years, but if the radio units part number is the same you should be fine. The biggest problem here is that this same radio was used on other models, like the Cruze, which have a different keypad layout. So there's additional programming in the radio for that you have to retain. Like model to like model, with same part number, should be ftw.
I’m trying to replace my 2015 Camaro display control module with a refurbished oem one, that doesn’t need to be reprogrammed?
If you're buying a new or _remanufactured_ one from ACDelco/GM that's correct, the radio will be setup to auto-learn the VIN out of the box. This is true for _most_ GM replacement radios, but you should confirm with your local GM dealer to be sure (even if you are purchasing it elsewhere they will know such details about the particular radio part number). If you're buying a third party _remanufactured_ GM radio, it depends. You would have to contact the supplier to find out if they have put the unit into a plug and play state or not.
However, _refurbished_ is just a cosmetic term, that term typically means the radio has just been cleaned up and any worn off buttons replaced, etc. No board level rework. So I would skip over _refurbished_ and focus instead on _remanufactured_ if you're looking to avoid any chip work or programming, unless the seller can clarify what the scope of their work was. _Remanufactured_ typically indicates putting the radio back into a new out of the box programming state. Of course, it could also just be a seller who does not know the difference in the terms. ;-)
@@DrShock My issue is only that my display screen is damaged. My display and control module are one piece. The radio main unit behind that is fine. I would be buying a most likely salvaged and used display and was unsure if that needs to be reprogrammed as long as I am not replacing the main unit.
Ah sorry, misread that first comment. The display screen has no sort of VIN lock or programming. It may be important to make sure the year and model of the salvage vehicle source is the same as yours though.
@@DrShock That very much helps! Thank you so much.
Also does it comes with the programming
Some CH341 programmers do, some don't. You have to check the particular eBay or Amazon seller before you buy for what they include.
My chip is ISSI 30341283GLA3 or that could be 30341203GLA3. So if my programmer turns off when I clip in the chip on the board, does that have to be de-soldered to be read ? Also which setting would I use for this chip in the IC menu ?
I did a "detect" and it said it was either Cypress I2C F-RAM FM24V01 [3.3v]. When I try to "Blank out" the Vin with the FF's and then write, it says that it was successful, but yet cannot verify, the error specifies the address where I made the change. I clear the buffer, then read and sure enough, nothing changed.
What year is the Chevrolet you're working on and is the radio a Delphi or Panasonic?
@@DrShock 2013 Verano, Panasonic.
I have not come across this flavor of memory used in a GM radio before. But typically a radio board is 5V, not 3.3V. So you have to be sure your programmer is working at that write voltage. Since you are able to read it, that would be my first suspect for the write not sticking. Second, I would desolder this type of device and read.write it out of circuit given the behavior seen with the testclip.
@@DrShock I did test the programmer and it is reading 5 v. With the black Edition programmer, do I really have to mod or can I use the jumper the pins for 3 and 5 v ?
will this work for 2010 camaros
This PDIM is a Camaro part originally, I don't know what year they started using it in the Camaro but it's definitely for a Camaro originally. It happens to work in the Cruze also because both vehicles share some common electronics. While the install is likely very different for a Camaro, I would expect the types of checks I go over in the video to apply to seeing if the Camaro has the necessary pre-requisites as well. In particular the PDIM firmware check on the radio.
could one just change EPROM chip? Or does it have to programmed?
No, the EEPROM contains programming. So just swap the original chip from the old radio into the replacement, rather than using a blank chip. No scan tool programming required unless you are attempting the unlock via GMs SPS2 instead.
@DrShock so to be clear, you can take old chip and install in the replacement. Yes?
Into the replacement radio yes, absolutely I mention this several times in the video. However, the radio part numbers must be _exactly_ the same for this to be reliably successful. And you must pull the radio from the same model vehicle (GM sometimes used the same radio in different model vehicles so they had different programming for the various button pads that were different between models).
thought you would like an update. Swapped EEPROM and it works Perfect. Thanks you Sir!@@DrShock
Which one Amazon do I purchase??
If you are referring to the CH341 EEPROM programmer, I only have experience with the one I linked in the card for this video - the Black Edition. There are several Chinese factories of this type, but they all have a similar cosmetic appearance. Some come with software, some do not. The video I did on the CH341 has links in its description for drivers and the programmer software I prefer to use with it for automotive projects.
Radio stopped working i was
Given a 2010-2011 dvd/Navi
From a friend but after install
Its locked. So the dealer cant
Do a vin relearn????
Depending on the model year and make, the GM dealer _may_ be able to perform a VIN relearn. The newer the vehicle though, the less likely they can as GM has phased out the reuse of previously used modules in newer vehicles.
The VIN can only be relearned at the dealer if your radio is the exact same part number and type that the vehicle was originally built with. The VIN is associated with the original radio type, if you try to upgrade to a navigation radio and you didn't originally have it, the GM dealer won't help you with that.
@@DrShock i called they said $179 and that not a garentee it will work. Watched
A youtube video on taking the chip out
That requires it to read a vin.
Can I just break it off will it still work ?
The only way to avoid causing permanent damage to the underlying circuit board functionality is to _desolder_ chips using the appropriate tools. Attempting to physically _break_ a chip off a modern circuit board runs an extremely high risk of permanent collateral damage to the circuit traces on top of the board.
That disclaimer out of the way, desoldering and removing the EEPROM was a hack that would unlock _older_ pre-2010 GM radios with just the loss of preset station functionality and/or a CAL error on power on. With newer radios, like the one featured in this video, I don't know what that same hack would cause.
Здравствуйте, есть вопрос к вам такой, не подскажите разблокировка головного устройства Navi 600, Navi 900, CD 500 на автомобиле Opel Astra j, Chevrolet Cruze. он аналогичен ? Говорят, что там нет такой eeprom, и их не возможно так разблокировать, по вашему способу удачно разблокировал CD 400, говорят и CD 600 и CD 450+ можно так разблокировать.
У нас в США этих радиомоделей, о которых вы говорите, нет, поэтому я с ними не знаком.
@@DrShock понятно, спасибо
GM recently changed to techline connect making it hard to bench program BCMs . The system will read the VIN from the bench setup ECU and won’t let you enter a new VIN and it will give error messages . Any way to go around that ?
Yeah, I saw that. And Techline Connect is currently *only* available to GM dealers so indy's and DIY'ers can't even access it.
But you can always bypass this kind of stuff by editing the EEPROM or microcontroller firmware directly. If you do alot of the BCMs, it's worth the cost of doing business investment to purchase a brand new GM BCM. Open it up, copy the EEPROM contents and save it. Then you have a _virgin image_ that can be used to _recondition_ any used module of the same part number back to the original plug and play state. Same technique that is done to remanufacture a BCM, along with fully testing them out for any electrical connector or sensor functionality issues of course.
If you don't do alot of them, then it's more realistic economics to unsolder and transfer the EEPROM chip between modules. Of course this is only an option if the original EEPROM is not itself defective. And the BCM part numbers have to match exactly for this approach to work.
Can you use SPS to Program and over ride the VIN? I have sent out several used radios to various Dealers, some claim they cant program them some program without issue? I would certainly pay money to anyone who can come up with a solution to clear the vin Via Tech2 or SDS.Has anyone tried to get the factory security code to seed and key program one?
For the years this video covers, impossible with a Tech2 alone. With a paid SPS subscription, I would suspect it only would work if the radio was the _exact_ same part number and it did not already have the latest calibration applied. It’s becoming very difficult to reuse GM modules without chip level work.
@@DrShock Have you tried a Denso Global A? 22879332. I have a SIM bench so I have never used MDI, SPS. It has never been a big issue until lately with the dealer unlocking them. I have a dealer now telling me it can't be done as they updated SPS and removed the feature?
No, I have not worked on anything but Delphi or Panasonic radios in Chevrolets. GM definitely removed the feature from the Tech2 many years ago. I would not be surprised if it was removed from SPS now as well. But these videos I've done get one past that by working at the bare metal level to unlock the radio anyway.
This is what I want to know. I have an 2015 Malibu with a junkyard radio. I have an gm programmer but I don't want to shell out $40 on sps if they took the feature off
If someone rolls back the Tech 2 firmware to version 30.004 you will Gain the vin relearn function back. On vehicles up to 2011. I have seen some people who lied to the tech 2 and was able to relearn the vin on a few vehicles newer than 2011 however I myself have been unsuccessful with the newer models. Also if they are using Tech2 win there is sometimes issues communicating with the vehicles
Just some information that very well may help.
Can someone provide a link for the tools needed to do this??
They are in the description.
@@DrShock understood that. Would you happen to charge an amount to get this done? I have seen your tools and just don’t want to convert the one to 5v and all. Just want to get my one radio to work.
@@mattjackson599 This video is for showing the electronics detail behind how this equipment works and interconnects to better understand how a radio shop will perform this VIN unlock procedure. Those with an electronics / maker background can then DIY it on a salvage yard unit and save themselves considerable $$.
If you're just looking for the outcome, you might be better off buying a replacement radio from a reseller who has already performed this same unlocking procedure beforehand - so that you can just buy the radio and plug and play style install it. From one of the eBay links in the description just type in the GM part number on the sticker from your original radio and some sellers doing this should pop up.
Hello !! Where I can get the software ?
Check the CH341A programmer video linked in the upper right - white RUclips circle _i_ icon
I have a 2014 equinox and got a locked message on junk yard receiver can I send it to you or bring it to you and unlock it for me? I’m in charlotte Nc
No, I do not do this sort of work for others. But figure on paying between $125 and $250 for a radio unlock to be done.
There are companies out there you can find via google that can perform a GM radio VIN unlock via a mail in service. Depending on the model year, you might be able to have the local GM dealer handle it for less. The newer the vehicle is past 2010, the less likely the GM dealer can unlock it though.
The point of my posting this video is for how someone can do it themselves for free instead, providing they have the electronics tools, skills, and years of experience necessary.
@@DrShock is it possible to remove the chip and reinstall on the new board
Yes, absolutely. And this would be the preferred approach for someone familiar with micro soldering but not comfortable with EEPROM programming. Just make sure the replacement radio is from the same make/model/year GM vehicle and that the white label part numbers are the same. While many GM radios may appear the same cosmetically, there are many different circuit boards and/or firmware programming inside.
@@DrShock thanks for the advice
Can i share your link video on my video im going to upload???
Linking via the RUclips URL to my videos, with channel attribution, is welcomed. What is not is plagiarizing or directly embedding my copyrighted video content into other works.
what happen if i put blank vin on a bcm?
You get a brick ;-) Unlike a radio, a BCM has several other mandatory fields including the security passcode to allow the engine to start as well as the mileage of the vehicle that has to correlate with the IPC modules value.
@@DrShock how I can see the passcode in the Eeprom?
The memory address where each data element is stored varies by vehicle model and year. This kind of information is *not* documented by GM. So you would have to know from trial and error experience with an EEPROM programmer where it is stored (likely in redundant locations like mileage) and likely it will be obfuscated rather than in plain text. I can't offer any specific assistance with this path, as I don't bother to edit BCM EEPROMs, only swap them.
Hey I’m planning on doing this but my radio is different I’ll give you the part number, is ( 22851302 ) do you know if I have to remove the EEPROM chip to be able to program it
Has anyone done it on this kind of radio
That part number is just the LCD display module. That module doesn't have anything to do with the radio being VIN locked. You have to get the part number off the radio head unit label.
@@DrShock thank you
@@DrShock I’m trying to do this but I’m not too good with technology and I don’t know which software do you use
