GM SPS Programming: Tech2 Tool Pass Thru Mode ECU TIS2Web TDS How to do a Calibration Update Reflash
HTML-код
- Опубликовано: 5 июл 2024
- This video is an historical overview on how you used to use the GM Tech2 scan tool to perform GM SPS Programming in what is known as Pass-Thru or Legacy Pass Thru mode for calibration updates. This could have been for the ECU or any programmable module in the vehicle, such as the EBCM, TCM, or Radio that you may have wanted to reflash. In this video we showed how you used to update the calibration flashed to the radio head unit as an example of the procedure. This is the second video in a series playlist I have done on the GM Service Programming System using the GM Tech2 and the various modes of updating the vehicle modules.
Note: The Tech2 is no longer supported by GM for module programming. In late 2021 the SPS and TIS2Web system was deprecated, and replaced with SPS2 and Techline Connect. These current software solutions from GM no longer offer support for the Tech2 tool.
GM SPS Programming Series playlist: • GM SPS ECU Programming...
WARNING: Pay very close attention to the instructions around power cabling and battery readiness as a power fluctuation during an SPS programming procedure can permanently damage a controller module. GM recommends use of their EL-49642 SPS Programming Support Tool attached to the battery to avoid this. You can also jumper cable another battery to mitigate this risk. But do NOT attempt to use a battery charger for this purpose though. I review an alternative product here - • 1995+ GM SPS2 Programm...
This video originally applied to the genuine Vetronix, HP or Bosch built Tech2 as well as high quality Chinese clones equally and for all makes under General Motors such as Chevrolet, Buick, GMC, Cadillac, Oldsmobile, Pontiac, Hummer, Saturn, Opel, Vauxhall, and Saab.. The programming was illustrated using a 2009 Chevrolet Cobalt LS and the www.acdelcotds.com subscription service features using a Techline PC using Tech2 legacy passthru mode to update the Radio (again, note this approach has been deprecated by GM since late 2021). You may need a USB to DB9 serial port adapter, GM recommends the Tripp Lite Keyspan USA-19HS adapter.
Originally applicable to model year 2008 thru 2013, which is when the Tech2 ended and was fully replaced by the GM Multiple Diagnostic Interface tool, or MDI and MDI 2 and TIS 2 Web subscriptions. This method is still available with TIS2000 and SPS for GM vehicles older than 2008 though, as an alternative to using Techline Connect and SPS2.

PSA: Starting in late 2021 GM ACDelco replaced TIS2Web and SPS with a new software solution - Techline Connect with SPS2. This new software no longer supports use of the Tech2 scan tool, it is officially obsolete as far as GM is concerned.
While you can still use the Tech2 for diagnostics, as a free non-subscription alternative to GDS2, you cannot use a Tech2 with SPS2 for module programming. You will have to either use TIS2000 offline, for vehicles 2008 and older. Or you will have to use a different J2534 compatible tool like the GM MDI or MDI2 with Techline Connect and SPS2.
So, if i understand this, i have a flash i need to download to a 2005 Corvette, 18-NA-346, for a column lock issue (released in 2018). My Tech2 is now obsolete for this task of updating this utility file?
For performing calibration updates, that's correct. The latest Techline Connect upgrades the system to SPS2 and that requires either an MDI or an MDI 2 interface to the vehicle. The Tech2 diagnostic functionality is delivered over either of these two J2534 interface devices via a Windows based emulator, Tech2Win, for older vehicles that require that. You can still use the Tech2 with SPS on TIS2000 (the obsolete DVD version) for calibrations released prior to 2008 though.
@@DrShock I’m trying to add the front and rear heated/cooled seats from a 2006 Escalade Platinum to my 2003 Yukon XL 2500 Quadrasteer. Most people replace the BCM to have the functions work, but I would lose quadrasteer. How can I add this functionality? I plan on removing all relevant wiring and placing in factory locations in the Yukon but does the BCM need to be programmed, and can it be done with a Tech 2?
Typically you cannot change the options in the BCM from how the vehicle was originally built by VIN. I'm not directly familiar with the BCM on that year truck series, but you would have to determine if the BCM has RPO (regular production options) that you can manually select or whether it is the more common type that is programmed by what GM calls a _calibration_ which is downloaded by VIN. In the latter case, you cannot change the options in the way you seek. I would suspect the forums you're reading about this have folks transferring the whole BCM because of this calibration fact. But it could be just because none of them own a Tech2, or have access to a MDI J2534 interface with Tech2Win emulator on their laptop. Both are very pricey tools.
When swapping out the BCM, and not having these tools to reprogram it, I would also expect the mileage to be wrong and _possibly_ DTCs posted for any missing RPO modules which can prevent passing state inspection in some states.
@@DrShock just bought a tech 2 for my 2103 chevy equinox that I think has a bcm issue. so what your`e saying is that the tech 2 is no longer viable option to scanning and reprograming it. I would have to get a mdi 2 instead.
Great video, thanks! I did discover that I have to logon to the GM website first to make things happen, not Techline connect first, even though I currently have the browser active on the website. At first, I couldn't figure out why it said my credentials were invalid when I tried to logon to techline connect first. I then logged into the website, and bingo, techline came up and I saw tech2 pass-through, and all of the goodies that us techies like! now, I need to calibrate my son's Saab 9-7X steering wheel angle sensor, and see if there are any modules that need updates. Thanks for enlightening me with your awesome video! Very smooth instructions!
Your videos gave me the confidence to pull the trigger to purchase a tech 2 clone. I am extremely happy with it. It works just like the real one. I got to use a real tech 2 while working at a chevy dealer. So far I have not found any differences besides cosmetics.
Life saver thanks 🙏 😊
Hi, thanks for the video! I have imported 2013 ATS from Canada to EU without GPS navigation. Can I upgrade/install it by SPS programming technique or do I need to replace HMI module for EU version and then reprogram (VIN must be set) ?
Great video. Finally found relevant info on GM programming. Question, I run an independent shop, installing a rebuilt 6L90 in a 2012 2500HD and need to program the TEHCM. I know this vehicle is not a CAN vehicle. Should I buy a MDI 2 and subscribe to GDS2 for 3 days and SPS for 1 vehicle or is there a better option that you would recommend? I don't have a Tech2. Also looking to future proof tech at the shop for newer vehicles.
Thanks for your help.
Thanks. For a 2012 vehicle you could go with an MDI rather than an MDI 2. I don't believe the MDI 2's unique new protocols start being required until Caddy CT4/CT5s and Corvettes from 2020 upwards, though that list will continue to grow and expand that's also going to be limited by GM's moving away from combustion engine powertrains and aggressively into electrics on their 2035 electrification roadmap plan. With an MDI (either 1 or 2) you can have Tech2 coverage for legacy vehicles using the Tech2Win emulator sub with Techline Connect, so you don't need an actual Tech2 as a professional shop imo.
For an individual or prosumer user, I'd straight up recommend an MDI clone. But while they, despite the fake news to the contrary, are 100% compatible with Techline Connect (SPS2, GDS2, and Tech2Win) they are not as robustly constructed and I wouldn't see them holding up long to shop drops and abuse like the original Bosch one. The MDI2 clones btw are not _real_ yet, they are currently just cosmetic copies of the same MDI1 boards. So for coverage on 2020s that require an MDI2, only the real McCoy will suffice today.
So bottom line, I'd look for an used genuine Bosch MDI unless you do this alot. If you did these jobs alot, I'd instead suggest an used genuine MDI2. Hope this helps.
@@DrShock Perfect! Just the knowledge and help I was looking for. You are a wealth of information. I don't do this a lot. Thank you so much for your fast reply.
So just to clarify, get an MDI 1, subscribe to GDS2 and SPS and I'll be good to go?
Yeah, that's what I would do in the situation you've described. Used genuine Bosch MDI1, rather than Chinese clone. And _weekend_ subs to SPS2, GDS2, Tech2Win as needed that I'd charge to the customer. It's like $30 or so, check at www.acdelcotds.com for the current rates.
For a DIYer, or prosumer, I'd always suggest a Chinese clone of the MDI. But for a shop you want some more ruggedness to the outside case and inside electronics. The clones are 100% compatible software wise, but if you drop them they are more likely to be damaged than a real Bosch.
Awesome video man, so basically the TIS2WEB turn the Tech2 to into J-Box and programming has to be done thru the PC for 08+ models ? Will this work with a good quality J2534 Box like the Autel?
ACDelco TIS2Web does support non-GM scan tools that are J2534 compliant yes. You may have to select J2534 manually, and for Autel I would suspect it has to be the GM version of the Maxiflash. But I've never used anything but the Tech2 or MDI tools myself.
Tell me about the bricked issue...I bricked my 2005 GTO E40 ECU because of what I think was caused from low voltage or interference. You really need a good battery charger/power supply that puts out clean power and adjusts it current output based on demand. I had to purchase another ECU preprogrammed and am having issues with it communicating with the PIM and BCM for the VTD relearn. Lessons learned....🤦🏼♂️
Newer comment on an older vid, but AMAZING info. 1) Thank you for these! 2) 2009 Saturn - If I have a comp, not a laptop, can I install the ECU reprogram into the Tech2 and walk it over to the car using Tis2Web? I'm assuming Pass Thru is for when it's directly connected, but wonder if the other Tech2 option is what I'd need. Thanks again!
Thanks. Well TIS2Web has been discontinued by GM. So when you go to www.acdelcotds.com what they have now is Techline Connect. And it's support for the Tech2 is very limited, no remote mode anymore. Just the pass-thru like you see here. The Techline terminals stopped being desktop PCs with DVDs and TIS2000 at the GM dealerships around the time the MDI tool and TIS2Web came out (circa 2008 or so) and moved to only supporting laptops. So GM doesn't really cater to anything but a laptop nowadays.
For a 2009 GM would expect the MDI tool to be used, rather than the Tech2 with a CANdi module. A 2009 is too new to use TIS2000 as well.
@@DrShock Thanks for the reply and info. VERY valuable! So if I had a laptop, and needed to reflash my ECU, would I still be able to use the Tech2 and Pass-Thru mode to make that happen, exactly as you did in this vid? And could a Windows 10 now be used, as opposed to the XP limitations? THX AGAIN!
I believe so, I haven't had a need to do a calibration on an older module yet since Techline Connect went live at the end of last year. But it's supposed to still support the Tech2. You have to manually select the tool though, it defaults to MDI or MDI2 now. You might want to call the ACDelco TDS helpdesk before paying for the weekend subscription, to make sure it's all good.
need a video like this on how to program a new BCM on a 2007 G6
Working on it for a Cavalier/Sunfire. But for these years use the Tech2 by itself, no SPS. Go into Diagnostics, build the car, and then Body. Select BCM, then Special Functions, then Setup New BCM. For these years only a brand new GM BCM works, there's no support for used ones as the VIN, odometer, and other info was write once and GM prevents the tool from updating it.
@@DrShock when setting up the new BCM are you able to enter in the correct odometer mileage and vinyl number?
In my experience, with these older vehicles that store it in the BCM, yes you should get prompted for the mileage by the Tech2 as long as its a brand new virgin BCM. If the Tech2 detects it's used, it won't let you change it. Past that you will get to pick the regular production options (RPOs) like the radio, cruise control, XM, etc. This varies across models alot though, and the older the vehicle the less was actually in the BCM. I've never seen trim numbers (vinyl) in a BCM myself, only hardware RPOs. But then I don't work on vehicles newer than around 2013.
I think your the best person to ask , so if I set up a brand new BCM and PCM on a bench harness and program a module like a GM lan radio - it should stay NO VIN correct ? Because it will not accept any VIN from the BCM/PCM
Both a brand new PCM and a brand new BCM will *not* have a VIN out of the box of course. They will have some default value in the EEPROM memory location where the VIN goes though as part of the virgin image from the factory. I have not attempted what you described here as not performing setup on the PCM and BCM first would not be a normal repair approach, but I would expect the Tech2 to generate an error message of some sort in attempting what you are trying. A module like the radio will still find a no VIN match condition and maintain a Theftlock state because the BCM does not have the _same_ VIN it has stored already.
@@DrShock thank you so much . I have seen a discussion someone using a virgin BCM on a bench setup and programming a GM HMI unit so it doesn’t accept any VIN when it reboots after programming it . I will attempt and give updates
thank you! how do I install software (new without o/s) on tech2?
The Tech2 stores everything on the linear flash card inserted into it (looks like an old PCMCIA card but its actually a special kind of memory not used in PCs). There hasn't been an update to this since 2013, last North American version was 33.004. If your's is older, you can update the cards contents using acdelcotds.com website, but it will cost you $249.00. Best to get this "with your Tech2" ;-)
Thanks for the video! I will be addressing my son's 2008 Saab 9-7x (AKA Chevy trailblazer, LOL) and need to do a steering wheel angle sensor calibration. I noticed that the ACDelco TDS purchase website says $45 for 24 months for all modules, and no longer says only 1 programming per module. Looks like they changed to a better deal. Have you noticed that? Am I correct in seeing this? I do have a GM card in my Tech2 now, ver. 33.004 Thanks again!
It's been all the modules you can do on a single VIN for two years for a long while. I don't recall how far back, but at least 2018 or so.
@@DrShock All I was saying is, your screen shot say "all modules, once" for 24 months. The website currently says "All modules for one vehicle (VIN)", which would indicate unlimited module programming for each module if need be, for 24 months per vehicle vin. Will this work with Windows 10?
@drshock Thanks for this video! can you please tell me, which type of program do you use in this video, win XP or win 7, and which operating system do you use, 64-bit or 32-bit? i also want to know, which version of Java do you use and which browser is it?
I'm following the GM hardware and software guidelines published at gsi.ext.gm.com/userguides/Aftermarket%20Infrastructure%20Guideline%20v1.0.pdf where the most important thing to notice/get right is that the Java runtime has to be 32-bit whereas the OS has to be 64-bit.
@@DrShock ok, thank you
Im programming a 2011 impala bcm right now and I'm having issues setting up the bcm. I read another comment where you said newer cars would be able to program info without using SPS. Can this generation impala be done the same way? Ive done the 2 options provided but i can't program the VIN to the bcm.
I'm only familiar with two methods myself, one is very old where you setup a new BCM using the Tech2 alone (I presume this is what you were referring to). And another method is where you need SPS on TIS2Web (www.acdelcotds.com). Some older BCMs are completely non-programmable and you have to replace with brand new - ruclips.net/video/Chy9pIzoguA/видео.html . I haven't worked on a 2011 Impala, but I'd look first for the BCM setup menu in the Tech2 like I show in that linked video for 2005 models, I doubt it's there in 2011 but worth checking. If not, I'd look at what TIS2Web showed for SPS options on the BCM tab for this vehicle. There's got to be a path where for a new BCM setup you can set the mileage and/or VIN along with the options the vehicle has (like cruise control yes/no, etc). In most cases you cannot repurpose an used module, as the GM approach was to use a new one only for repairs so would suggest that route for the least hassle.
@@DrShock I was able to get the BCM programmed using the SPS procedure in your video, so basically any 8th gen Impala has to use SPS to program any modules. Turned out that the RS-232 to DB9 adapter wouldn't automatically install its drivers so I had to do it manually. Thanks for making this video, it helped fix one of the issues I've been having while narrowing down other issues that need fixing.
Hi, thanks for that informative video! I'm having an issue when the SPS is attempting to communicate with the Tech2 for passthrough...I see the tech2 screen change but then the error message shows up in SPS "M4404: Please restart your Programming interface and press OK to retry! Press CANCEL to abort". I've got the usb-serial port set up & working, 115200 baud, COM3.
M4404 is a communications problem between the Tech2 and the laptop. I would check vehicle battery voltage, that the Tech2 is being supplied with its own separate 12VDC power via its AC adapter, that the serial cable between the laptop and Tech2 is good and with solid connection at both ends. Also do not have anything else running on the laptop but the browser hosting SPS, do not use the laptop for anything else while the SPS Java applet is communicating with the Tech2.
@@DrShock Same here. I'm using the Tripp Lite Keyspan High-Speed USB to Serial Adapter and connection is good. The Tech 2 is powered via AC. This laptop is strictly for messing with my 2007 Saturn Ion. I'm beginning to think this ACDELCO website purchase was throwing money into the wind.
@@bootoxkikka I know this is old, but wanted to provide my update. I found the same error...when I had left the plug connected to the bottom of the Tech2 (even though it was disconnected from the vehicle interface) and also connected the Tripp Like Keyspan adapter to my laptop. When I unplugged the adapter to the bottom of the Tech2, and restarted the unit JUST WITH THE Tripp Lite...the system proceeded as expected. Just my experience, but for those who also struggle...this could be a reason why.
Will all of this work for a Saab 9-7x, since it essentially is a Chevy Trailblazer, with saab headlights? My current Tech 2 is setup for my 2 saab 9-3's. I would most likely select 2008 Chevy Trailblazer, and yes, I do have a GM PCMCIA card for the tech 2. Basically, i need to start out calibrating the steering wheel angle sensor, first, then do other stuff.
In my past experience, the Saab has its own PCM calibration so you'll need the Saab firmware card for the Tech2 to program any modules on its bus. I have never tried using the regular GM NAO firmware on anything but a USA based brand vehicle.
I have a 2007 9-7, and it shows up on my GM 33.004 NAO card as a Saab 9-7. I also have full programming ability on the 33.004 card.
I do have the Saab 148 card fo my 9-3, and the 9-7 doesn't even show as an option.
If I wanted to remove the speed limiter on my 2010 STS since I have upgraded the tires would this subscription allow me to do that?
The GM tools do not allow you to make modifications to the programming as the vehicle was originally built. These tools are just for repair and diagnostics.
Can you help me figure out which device I need to reprogram a 2012 radio for a 2007 GMC? I thought my Yukon was CAN, but I'm seeing most boxes say 2008 and up.
I think you're asking Tech2 or MDI here right? And if so it's based on your vehicle not the radio, the scan tool is going to be communicating with the vehicle. For a 2007 the native tool of the time would have been the Tech2. But the MDI can emulate a Tech2 with a subscription to a software emulator GM calls Tech2Win on their ACDelco TDS website for use with older vehicles. The MDI will handle CAN (GM LAN) built in but the Tech2 will need a CANDi module between it and the vehicle to translate. The bigger challenge is the 2012 radio is not a stock GM part number for model year 2007, so SPS won't show you a calibration file for it.
@@DrShock I'm only seeing people say "you need to program this to work in your vehicle," or "take it to a dealer." Does this mean clearing the theft lock? Doing a VIN relearn? I picked up an MDI based on your advice that comes with a Win7 hdd, so hopefully I'll be able to do this. And I guess I just do the $40 subscription option for programming. Thanks for your help!
If you had a non-navigation 2007 radio from a different GMC than your own but the same GM part number, then with just a Tech2 (or MDI with Tech2Win) you would just do a VIN relearn procedure to unlock it. Since you're taking a 2012 one, this may not work but its the first path I would attempt. You don't need a PC connected for this one for 2007 (though with an MDI of course you would just for Tech2Win). And yeah what this procedure does is re-marry the radio to your VIN and thus release the Theftlock II lock.
The wording when you purchase the one vehicle for 24 months is a little strange. Does it only allow you to flash each module once? IE. I cant go back next year and flash a new update(if there was one)?
You can do any updates for the one VIN during that time period. Though this is really only useful for newer vehicles. GM stops updating the calibrations pretty much after the warranty period in my experience.
they allow you to buy a subscription as a private person ?
Yes, of course. It is your protected right by law in most states of the USA for the manufacturers to provide non-dealership service options.
I purchased the one vehicle VIN module update package and am trying to use it but it keeps getting stuck at the same place. I'll select tech2 legacy pass thru on the SPS app, and when I go into settings in the SPS app, I click test connection and it always fails. I have my Tech2 plugged into the serial adapter, powered on, and matched the COM ports and baud rate with the ones my laptop gave me. However, every time I click test, the Tech2 switches to the screen with the symbols on it indicating that it is communicating. I dont know what to do. It says connection failed, but it is clearly communicating with the tech2 since the screen changes each time I click test connection.
Some things I would check, did the Tech2 pass it's internal diagnostics tests particularly the serial test with the loopback connector plugged in? If that works ok I'd suspect the USB to serial adapter. There are some other comments in this video that I recall some links around adapters known to work with the Tech2 - some are not compatible with it.
@@DrShock I figured it out. instead of using pass thru mode, I switched it to j2534 tech2 mode. it communicated through that and I was able to update every module except the rcdlr in my 2008 G6.
So reading the description, you can no longer program even a 2012 with the tech2? Did I interpret that correctly?
Correct, no module programming anymore since Techline Connect came out last year and GM deprecated SPS (replaced with SPS2) and the Tech2 support. You can still, of course, use a Tech2 for diagnostics and functionality similar to the more modern GDS2.
Ok, after decades of dealer work, my Hewlett-Packard TECH2 card can no longer be updated pass the 2013-2014 model year! Is this right? Retired and fixed income is no fun, but a storm destroyed my wife’s older GM. I want to get a 2015 Malibu LT and still like to be able to diagnose the problem...Even if I have to take it in. The techs I worked with have retired and some may know me, but just unsure in October of 2021 what my TECH2 will work with! Thanks to the Chinese flooding the market with cheap clones that break down-no repair and some have messed up module(s).
Any thoughts that could tell me what to expect?
The carline Malibu ran from 2012-2015, then change in 2016. I know I have lied to the TECH2 in the past to have it function fine on a 1 year newer model. I guess looking for current help as I don’t want to walk into a dealer tech for nothing! Thanks. DK, Omaha.
Yeah the Tech2 is retired as of 2013, started getting model support dropped in 2010. You can still use it as a J2534 passthru with www.ACDelcotds.com for SPS. But for tests and diags you'll have to use GDS2 on the laptop now. Here's a GM list of what requires an MDI now (or J2534 passthru) for SPS/GDS2 - www.genuinegmparts.com/pdf/positionstatements/vehicles-supported-by-GM-scan-tools-reference.pdf
Where do u get trans operating system number with the teck 2? I can't find it anywhere.
I'm not sure exactly what you're asking for. There is no such thing as a transmission operating system number in GM. If you mean the Tech2 operating system version number, you should be seeing that when the unit is first booting up, the version number of the operating system level is printed before you press enter to get the menu.
To get my truck trans tuned u need it for trans module.
You can use the Tech2 to check that your transmission module has the latest GM calibration. But you cannot use a Tech2 to alter the calibration or "tune" it in any way though. If you're just looking to validate the factory calibration, then it will show up in the list as shown in the video at 5:55 where you will see TCM (transmission control module) in the menu to choose from.
I just need to confirm which one I have for the tune. Ile check out the video. Thanks
Second question, my tech does not connect with laptop anymore and i to sang rs232 cable yet is not working. What could be the problem?
Did you do the communications diagnostics check shown in the video?
do you know how can I force SPS to reflash again?
I did update a module and I got an error at the end. I can access the module but it is not working properly, so maybe a reflash would fix it
But SPS tells me it has the latest calibration and won't reflash :(
If you can read the calibration, that's not the issue. You cannot reflash the same calibration on a GM part anyway. You could if there was any problem reading the calibration, but if its readable SPS will just tell you that you have the latest calibration already.
ok, so if the calibration is fine, then it means it;s just not communicating to other modules properly
any other reason why it would not work?
it's the battery charge control module from a Volt/Ampera, and after updating it won't charge from AC, it says that P1EE6 Battery Charger AC Voltage Not Present
obviously the module worked fine before the update, so it must pe a software issue...
In these kinds of situations I pull a comparable part from the local pull your own parts salvage yard vehicle for testing. I'm not familiar with this particular voltage not present error, but having another to test with helps zero in on root cause. While one would intuitively presume its a software/firmware issue, it can also be that the flash operation itself finished off a dying module. I have seen this at least once and the swap confirmed it wasn't the calibration level itself, but rather just a dying part.
So the answer to my question is: in order to reflash again with SPS you need a VCI code. You need to be a dealership in order to request and receive the code
Once entered, SPS will ignore all calibrations on the module and reflash
Reprogramming worked, and now the module works!
Hi let me ask you something. As you was showing the option to pay on for subscriptions on the acdelcotds.com you then jump onto another screen and as you did you said tech line information and there you shows a screen that looked like the TIS2000. is this page part of the prier acdelcotds.com or did you navigate to another page? Thanks
That's TIS2Web, the replacement for TIS2000. Looks about the same as it did in the 1990s. You do not get to see that until you have a paid account, then when you log in instead of a subscribe button you'll get a button to launch the SPS Java applet. Or GDS2 or Tech2Win, whatever you've paid GM for in that particular account.
@@DrShock Ok now i'm understanding, so if a pay the $40 they say you get 2 years to program 1 or more modules in only one vehicle right? If so then i got time to figure out how to navigate the TIS2web! lol
You can do anything SPS but just with the one VIN correct. For a DIY that's quite a good deal. For a professional garage, it's probably a bit pricey if they just needed to do one module for one customer but at least they got the option vs sending their customer to a GM dealer.
@@DrShock Well for me doing one vin is okay, because I'm starting out new with programming car modules, yet i'd been doing softer programming using my Autel Elite on things basic. The kick in the ass was with my Autel I got 2 years of software update along with a subscription for BMW and benz meaning I can do unlimited module and i didn't and my sum expires at the end of this month! Reason i didn't know because although this tool came with the J2534 i was told I needed a laptob using the dealers sit, but not told only for U.S cars, so I and figured the same goes with BMW and Benz cost$$$ was i wrong. Anyway it's time for me to get into programming because every car i send out is money lost!!
@@DrShock I know i wrote you back already, but there's something i forgot to ask, Drivers do i need to download any type of Drivers for the USB adapter or the Tech2 and If so where can i find them? thanks.
It’s incredible how well the clones look like the real tech 2. Honestly the original tool probably was made in China so it’s probably the patent ran out the Chinese sell it cheap
If I send you mine and pay you could you fix it where the thing quits rebooting when starting the car for say an evap test. I’ve changed the voltage regulator I don’t know what else to do. If your interested let me know
@@philh9238 That particular behavior cannot be repaired, the clones don't have access to a proprietary voltage device from GM that the genuine Tech2's have (its not sold to the public and heavily patent and license protected). That device allows the Tech2 to function down to much lower voltages caused by battery voltage drop off during engine cranking. I mention this behavior in the video description here ruclips.net/video/VAmGybyWfJ4/видео.html
I changed out the regulator with the part number you mentioned still does it. So it just sits in my bottom drawer of my toolbox since September. Guess that’s what happens when you buy cheap Chinese junk 😂
@@philh9238 So if you read the detail on that video in the description, that repair is only to get the clones to power up again if the voltage convertor fails outright and replace it with a branded one that will be much more reliable. But there's absolutely no way to correct the design limitation of voltage dropping out during cranking with off the shelf electronics. I wouldnt call the clones "junk" since they are basically the same boards as the original GM one, just some different chips here and there that gets it down to $300 range vs the $3000 range. If it were not for them, no average home owner could afford to acquire such dealer level diagnostic tooling.
Okay thanks for your time replying. I misunderstood the meaning of the video so I thought that’s how you were fixing that issue. So how do you personally handle that issue on your own? Just asking
What type of Tech 2 are you using is it a clone or genuine GM Tech 2?
High quality clone, absolutely zero difference from original as far as TIS2000/TIS2Web goes. As an individual owner, buying a genuine unit is throwing money away. Have been using this guy regularly for about 3 years now with no problems at all. When new I upgraded the voltage converter, which is the one weak spot in them.
Do you have a seller you could recommend buying one from, or what to look for when buying a good quality clone?
Thank you. Chris
For the MDI, I have a separate video up for that. For the Tech2, I would recommend eBay, and looking for a US based seller to avoid drama. I believe at this point there is only one supplier left of these Tech2 clones and fortunately its the higher quality one, so as long as you see the complete set of all the cables and adapters it's likely the high quality one. Weakest link is the PCMCIA flash card, the clones of the linear flash memory type are not well made so you have to be gentle with them.
Thanks for the video but my TDS does not open i don't know why
You need a fairly current browser to run www.acdelcotds.com
Why is it that the Tech 2 in SPS/"request information" does not list Saturns? In mine it doesn't. What make can I use?
The only Saturn model I'm aware of that needs it's own separate PCMCIA card firmware is the Astra. The other Saturns should be in the GM North American PCMCIA card, firmware version 33.004.
@@DrShock Hey thanks! That's the version I have, (It shows it on the menu upon start up menu). Yeah in my Tech2 the first step in SPS is to request for info and Saturn's aren't listed on mine, (SPS version is 2.080). You think my PCMCIA card needs updating?
If you don't have an Astra I don't think so, card wise. And I'm going to presume here you've purchased a TIS2Web subscription and are not using something that may have come bootleg with a clone scan tool from China. Be sure you have set the serial COM port speed in the SPS Java applet like I mention in the video. Also I have read in forums that aftermarket radios will definitely prevent communication with the Tech2 on a Saturn of all things, so if you have one disconnect it and retry. Same for any aftermarket devices that provide steering wheel audio controls or really anything hanging off the radios rear communications bus connector harness. What year is your Saturn? If it's 2008 or older I would try just using the Tech2 with the TIS2000 DVD that should have come with your Tech2 instead of TIS2Web to at least see if I could communicate with the BCM and ECU modules to get the information populated. If none of that works, since you paid for a TIS2Web SPS subscription you are entitled to support from ACDeltoTDS so give them a call at 888-212-8959
@@DrShock Correct I do have a subscription, it's a 2007 Saturn Ion, (and no after-market radio). Before calling them I want to make absolutely sure it's not something I'm doing. With what I wrote I first tried TIS2000 after being installed and it requires one to go to SPS on the Tech2 menu, (I dont mean on a website), next, 'Request Information', then enter the make of model. That's were I see a majority of makes listed except for Saturn. That's the problem I'm having with the Tech2 and TIS2000 for Saturn. Cant populate it if it's not listed on the Tech2 Scanner under the SPS menu.
@bootoxkikka hmm, so when I take my Tech2 and select Diagnostics, 2007, Passenger Car. I then get Saturn as one of the choices number (8) at the bottom of the first page make list. That's without TIS2000 or TIS2Web, just the Tech2 sitting all by itself connected to a Chevy for power. So if you're running "North American" firmware 33.004 version and you're not seeing Saturn as a choice if you go the steps I did, then I'd have to believe it's a firmware/PCMCIA card problem with the file(s) saved on that image because mine is a clone and it shows Saturn just fine - and I don't have a Saturn handy though but I still loved my 1992 SL2 ;-)
Can I program 01 impala bcm with just the tech 2 alone
2001 Chevy would certainly be within the makes and model years covered by the Tech2. But not by itself, you would have to have the TIS 2000 software as well at a minimum. Or a TIS2Web sub as this video covers. Now regardless that's for setting up a brand new replacement BCM from GM/ACDelco. Used salvage yard BCMs are a mixed bag, some years you can some years you cannot. I'm not sure about 2001 sorry, perhaps another YT vid will cover this for you.
@@DrShock yes I am going to get the tis..2000 software I have that gray phone cord and I have a hookup on my computer for that cord if that will work or will I need to convert to a USB cord end
Native serial port is best, USB adapter as a last resort. Only a few work, I believe some other comments mention that.
What card do you have in it?
GM NAO
So In your opinion is it worth buying a genuine tech2? Also does the tech2win do everything the tech 2 can do? Do you still have part numbers for cables and adapter to USB?
Thanks
If you can find an original genuine Tech2 that's in good condition and hasn't been beat up in the dealership at a good price it's a better choice than a clone sure. But typically they are either going for 2-3X more than a clone, or pretty banged up and repairing them just isn't feasible. I've used the high quality clone model for close to 4 years now and never found anything from the GM services manuals it couldn't do. I've never bothered to subscribe to Tech2Win for my MDI clone, because I have the Tech2 clone. But my understanding is it can do anything a Tech2 can and is mostly there so you only need to own one tool (MDI or MDI2) as a dealership. If you look thru the comments I believe there's some info on USB adapters that folks have found to work. Originally GM only recommended the Keyspan USA-19HS adapter from Tripp Lite.
@@DrShock Awesome thanks for the help I bought a 2006 chevy truck and was wanting to see if the truck has adjustable parameters that can be changed with the tech 2 as my dodge ram has with the drb3 tool. Do you know if there are options for that or is the tech 2 just used for fault codes and programming?
Thanks
Every GM vehicle is different in some respect on the tools menus, and I'm not personally familiar with 2006. But most of the time GM limits adjustable parameters and options to those that came with the vehicle when new, so definitely no tuning supported.
There is a cracked version of the Tech2win software you can get from China that works really good.
Hi I have a 2007 cadillac escalade that had the basic radio and bought a used one from another 2007 but is the navigation radio. it turned on but the screen says theft lock. I got a tech 2 but it wont let me do a vin relearn. I saw then online that I needed the 30.004 version and mine is the 33. What would you recommend me doing? thank you.
I've never heard of downgrading the Tech2 firmware to an older version, certainly no such GM technical service bulletins I could find recommending that. Sounds like a wild azz guess someone made because it appeared to resolve their issue. This is an old tool and the firmware hasn't been updated in a very long time, the only version to be using for North American vehicles would be 33.004. Other country areas would have different versions as their last revs. That all said, for 2007 the Tech2 is the right tool to be using for that vintage. But the magic word is "navigation" radio, did you select this option on the Tech2 after each prompt? Here's a link I had from awhile back with the menu steps that may help you - duramax.onlinedesk.net/navinstall/THEFTLOCK%20CLEAR%20PROCEDURE.html
@@DrShock yeah i saw that but it doesn't say navigation radio on mine just radio.
This radio upgrade is the correct part number for 2007 Cadillac Escalades though right? And you didn't have to modify the wiring harness or such to connect it up? I do know you won't get Tech2 support for trying to put a radio into a vehicle that wasn't originally available as an option at the time. Do you have a TIS2000 DVD that came with your Tech2? If so you could try doing an SPS calibration update and see if it lets the vehicle body control module learn about the new type of radio like this other video I did - ruclips.net/video/Nr_eYexAAV4/видео.html
@@DrShock not sure if correct part number but it hooks up with all the connectors no problem. yeah I got the tis2000 CD. I'll probably end up doing that.
How can I do idle reset on 2004 Silverado
You're looking for the Idle Learn Reset likely under module setup for the PCM. Haven't done this so that's about all I can suggest
When you try to program some radios on the SPS using MDI there is no “radio” choice on some vehicle models . How to dealers program those Radios ? Or do they have a different subscription to be able to program all modules ?
These approaches change with the times/model years but learning the VIN and "calibrating" the radio is usually found somewhere in the Tech2 menu (or Tech2Win emulator for the MDI) for vehicles up thru around 2008. After that it should be found somewhere in SPS as part of calibration, but again how varies by model year and vehicle make/model in my experience. Modern navigation radios also have USB based programming that you have to consider, that do not even use SPS. I don't have alot of experience dealing with radios and even then just when it's the same make/model year swap.
DrShock so if I buy the tech2win software I can just use my MDI to act as a Tech2 device ? I appreciate your help .
You would have to get a subscription to the Tech2Win service, but yeah that lets an MDI emulate the Tech2 for older vehicles. These various subscriptions can get pricey, so make sure you check it all out first. Sometimes it's just cheaper to have the dealer do it if you're not going to have a longer term need for the MDI.
DrShock perfect thank you . I have the subscription and I seen the Download for the Tech2win option but didn’t know what it was . Thank you again .
Which tech 2 clone is the best or all the same
I'm not sure if these are being actively cloned anymore. The MDI and MDI2 type clones are the more current tools. But you used to be able to spot the higher quality Tech2 clone by the fact that it came with all of the adapters, various power cable types, and loopback test adapter. It would also come with a copy of the TIS2000 software.
@@DrShock thanks been looking for another tech 2 with 32 card and tis 2000,,they all look about the same,,got a one now that works on my laptop,just no tis 2000, I still work on a lot of this old stuff,love you Channel keep up the good work
@@DrShock hate to keep bugging you but want to make shure I'm getting the right one,,
TIS2000 CD (included) will do up to 2007 year for GM vehicle programming. Does NOT include the software key. You'll need to obtain on your own or find a hack to unlock. Best source is acdelco website which costs $55 for 2 day access to the tis2000 SPS reprogramming .
Without a subscription to GM TIS2000, Tech2 CAN NOT :(1)Configure a "secured" BCM (GM says to get a new BCM in that situation) (2) Flash an ECM with new firmwar (3) Configure the anti-theft system
@@scotttucker4075 So that description is somewhat inaccurate. Thru 2007 model year is true for TIS2000. And the part about the security dongle (key) is accurate. But the acdelcotds website is TIS2Web, not TIS2000. There's no subscription fees or costs at all if it's actually TIS2000 on DVD they are including. There are no subscriptions to TIS2000, it came out years before such a thing was possible over the internet/web. So all that costs part is inaccurate (also TIS2Web SPS is currently $40 per VIN for 2 *years* now).
A _secured_ BCM I would presume refers to a locked BCM because GM doesn't allow you to reuse used ones once you program a BCM it's _locked_ from further programming on _most_ models. Even back in 2002 or so they were preventing this at the Tech2 level (scan tool reports locked BCM). I've got a few videos on this problem, you can't even use TIS2Web SPS to reuse it, you have to either get a new BCM or work on the circuit board chip itself. On the flash comment, I've got several videos on reflashing a PCM/VCM/ECM using TIS2000, you just have to be model year 2007 or older. Configuring anti-theft, again model year 2007 or older only with TIS2000. No subscription costs required.
If you are only doing 2007 or older, get a Tech2 clone with a copy of TIS2000 included. If you need newer, no other option but TIS2Web (www.acdelcotds.com) and there you would be better off with an MDI clone but a Tech2 + CANdi module can work thru 2010 or so.
If you go the Tech2 clone route, be sure you have a Windows 2000 or Windows XP PC around, TIS2000 only runs on that era of PC. And make sure you find a source for the security key dongle (most common is a USB type) for use with TIS2000. There is a _mod_ to hack out the dongle check, but if you're not PC savvy it can be more trouble than it's worth vs just getting the dongle key. Hope this helps.
What is the website to o update tech2
There hasn't been a firmware update for this tool since 2013, but it's where you pay for your Techline Connect subscription. GM does not provide updates for free. www.acdelcotds.com
Hello I logged into the address you shows www,acdelcotds.com and it looked nothing like what you shows. I only see the purchase if the downloads ad to cart, but i cant find anything that looked like the TIS2000. thanks
These website screens change all the time, no way any video can stay up to date in that regard. You can't get to SPS until you pay, then you'll be able to login and see the old familiar interface.
@@DrShock yes but the problem I needed to link my Tech2 to the service. I not sure if the RJ45 is hooked up right, so if i pay then cant get it to work i'm screwed
@@DrShock You didn't get into the cable that goes to the laptop. Is it a straight cable or crossover? does the RJ45 plug into the Tech2 and whats on the other side to laptop?
The cable to the laptop is a USB to DB9 serial port adapter. You then plug the serial cable that came with the Tech2 into that. GM recommends only one USB adapter, the Tripp Lite Keyspan USA-19HS model. But some years ago, thru trial and error, I found that some clone ones worked for me. Thanks for pointing this out, I updated the video description to mention the USB adapter recommended by GM.
@@DrShock Hi Okay i purchased my Tech2 with CANdi module used it's a Vetronix by OTC. I paid $1000 2 years ago, but never used it for programming because I didn't know how. The problem is it only came with the OBD black cable and CANdi module alone with 1 yellow RJ45 cable. Now about hooking to the web for programming, the Tech2 seemed to only have 2 receptacles on the upper left side of the tool one RJ11 and one RJ45 receptacle. It looked like you're plugged into the the lower one being the RJ45 correct? The yellow double ended RJ45 male cable does plug into the side RJ45 receptacle of the Tech2, but where does the other end go? Does this RJ45 other male end go into a RJ45 to DB9 adapter and then connects to a DB9 to USB adapter into the laptop? I do have the RJ45 to DB9, but not the USB, so i ordered USB 2.0 To RS232 DB9 Serial Cable Adapter Converter For PDA Satellite is this the wrong one? Thanks
I think it is misleading, until you read the fine print below, basically you can't program more than the modules your car has....but hey...you have 24 month access.🤦🏼♂️
GM sells the subscriptions per VIN / per vehicle, so yeah just modules associated with the one VIN for 24 months. For personal use though, it is quite a bargain as the average shop will charge you significantly more just for one module _not including_ the labor to R&R the module. For $40 you get 24 months of _any_ module on _your_ vehicle, for no additional charges. Your tools, your parts, your labor, your way - that's complete satisfaction guaranteed. ;-)
@@DrShock You can only program twice if you have 2 modules. I'm trying to trouble shoot my 2005 GTO and re link PIM to PCM due to me bricking original PCM, but I don't see that option with TIS2Web. These cars are a PITA as modules and security.
Interesting. I did a vehicle last last year on TIS2Web with an MDI and SPS where I updated four _different_ modules in one sitting, just doing calibration updates proactively for the owner. I can't recall any sort of limit in past years either with SPS (other than the fact you cannot reflash the same calibration twice), though I've never had a situation where I needed to do two of the _same_ modules in one sitting. As best I recall you need a Tech2 to do the PIM relearn. Or alternatively, Tech2Win. Here's a link to the GM service information in a PDF over at EFI Live for what you're looking to do: www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwii8qe73-fuAhVEmVkKHXraBN0QFjADegQIBRAC&url=https%3A%2F%2Fforum.efilive.com%2Fattachment.php%3Fattachmentid%3D8911%26d%3D1283265494&usg=AOvVaw1iVv3LoyYe4-88wbreQ4wd
@@DrShock I have a Tech 2 and have tried relinking via TIS2000, but will not do it. I have the PDF you supplied...👍. I don't see the option available when I try Tis2Web. I tried to follow what Spartanautoworks here on RUclips did to relink, but he showed the relink function and mine didn't. 🤷🏼♂️
Here is an e mail from Acdelco:
Vehicle Programming Software
"Includes: 24 months access to program all modules for one vehicle (VIN)".
If you program all the modules first the subscription then expires before the 24 months.
The limit is the number of modules in the vehicle programming of a VIN or 24 months whichever comes first.
