2002 - 2005 GM P11 PCM Salvage Yard VIN Reflash with SPS and Tech2 (Chevy Pontiac Olds Saturn)
HTML-код
- Опубликовано: 2 авг 2024
- In this GM Powertrain Control Module (PCM) reflash video we'll make use of a benchtop programming harness that simulates the Off Board Programming Adapter (OBPA) so that we can show how to replace your PCM with an used one from a salvage yard vehicle including reprogramming in the correct VIN and latest calibration software level (or of course to a new or remanufactured PCM from GM / ACDelco instead). You do NOT need this benchtop programming adapter harness I'm using to do the repair, you would perform the procedure I go over on your actual vehicle instead. However, you WILL need access to a GM Tech2 scan tool, as well as the associated GM TIS2000 software for Windows for the Service Programming System (SPS) functionality.
The example PCM illustrated in the video is from a 2004 Chevy Cavalier J-Body, and so what's shown would apply EXACTLY to these models / years:
2002 - 2005 Chevrolet Cavalier
2002 - 2005 Pontiac Sunfire
But the 2002 2003 2004 and 2005 series GM P11 PCM which was used in several other GM vehicles also, so the approach I'm showing would be applicable for these additional models / years too:
2004 - 2005 Chevrolet Malibu Classic w/ 2.2 Ecotec
2002 - 2004 Oldsmobile Alero w/ 2.2 Ecotec
2002 - 2005 Pontiac Grand AM w/ 2.2 Ecotec
2002 - 2004 Saturn L-Series w/ 2.2 Ecotec (LW200, LW300, L300)
The eBay and Amazon search links below are paid links, for which I may be compensated and earn a commission, if you choose to buy the parts and tools shown in this video thru them:
It is always preferable to use a brand new or factory remanufactured GM / ACDelco PCM for service and repair purposes, and the part number for the cars listed above for these years originally was GM 12576162 which was superseded in 2010 to GM 19210073. You can search for both, as well as other used PCMs of this same series: ebay.us/pTMYQB
There may be some exceptions to the above list for fitment of the PCM, check that any replacement PCM matches your original one EXACTLY in terms of the labeling on the part!
Buy a Tech2
If you are looking for a GM Tech2 scan tool as I was using in this video: ebay.us/SpDtiS
Buy a Tech2 USB to DB9 Serial Port adapter
And if you need a USB adapter, the GM recommended Tripp Lite Keyspan USA-19HS: ebay.us/QBOU1G or at amzn.to/2GEDwE4
If you want to save money of course, you can just use a salvage yard pull which was the point of the video. Just be sure you pull the PCM from the exact same make and model vehicle (preferably the same model year as well), and that the PCM label numbers match your vehicles PCM exactly. I recommend LKQ yards as they let you pull your own parts, and have a no hassle return policy if you pull a dud controller.
WARNING: When performing SPS operations in the actual vehicle, 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.
NOTE: TIS2000 was deprecated by GM in early 2008. Today we would use the subscription based TIS2Web as part of the ACDelco TDS server (www.acdelcotds.com) based offering to accomplish many of the same tasks, although both the Tech2 Remote Mode or the Off-Board Programming Adapter (OBPA) path are no longer supported or offered by TIS2Web.
NOTE: Be sure your USB to serial adapter device driver is configured for 115200 speed on Windows using Device Manager and set the COM port assigned to within TIS2000 for communication between the PC and the Tech2. GM recommends a Tripp Lite Keyspan USA-19HS adapter (USB to DB9 serial).

Great video how much equipment does a guy need to reprogram computers ford gm Chrysler I have a tech 2 dbr3 tons of other scanners and stuff
I have both a Tech2 and an MDI, both Chinese clones, that covers everything General Motors from 1993 thru 2018 just fine.
Great video , Thank You it's all a matter of buying the tools needed , Your saying Chinese clones work properly so those will do , I have one question , How often due You flash upgrade /program PCM ?
I'm restoring an 03 Cavalier , this is helpful , I can do that , thank You
It's not a common repair to replace the PCM, on the rare side. But updating to the latest calibration, I do that for any vehicle I come across. I view it the same as updating Apple iOS or Microsoft Windows. ;-)
@@DrShock would be be able to to provide the links for the clone tools and a link to the software?
Thank you very much. Very informative
dr shock, so the dvd tis2000 that comes with the tech2 i am able to reflash off-line with it till 2007.so it comes with the calibrations already? or am i missunderstanding? thank you for your time and your good work
That's right the Tech2 using the old TIS2000 DVD is completely offline, no subscription required. But it only covers thru model year 2007 (and I believe it is missing most of Saturn which had their own unique tooling back then). Down the road you can still use your Tech2 from 2008 thru 2013, but you'll need to pay for TIS2Web, with an online subscription (around $40 per VIN for 2 years).
When you said "Tuning tool to just go in and jsut change the VIN", do you mean like a KESS or KTAG or something like that? I have a spare ECM (e78) for my Cruze, and I need to program the VIN for my car after a botched flash. Problem is, I don't want to pay HP Tuners again for two credits to reflash my ecu for the same VIN in the same car. I have the hardware, but would I use something like WinOLS to change the VIN, or do you know of some GM specific software to do this? I am hoping you can point me in the right direction. Thanks.
There's nothing from GM but what I've shown here which is their Service Programming System (SPS). The Tech2 or alternatively the Windows emulator for it (Tech2Win) running with the GM MDI J2534 adapter for pre-2007 vehicles. When I made that comment I was thinking EFI Live, but not from personal experience. In most cases, since you mention a Cruze, it would be the GM MDI and using the TIS2Web SPS feature at www.acdelcotds.com (which is just the cloud version of the older PC DVD based TIS2000 I showed in this video) which is for 2007 and newer vehicles to change the PCM/VCM VIN. But there is that one situation where it could be a problem calibration version wise, and then you would have to go third party tooling but that is not a common situation.
If you replace a ecm and BCM at the same time do you need to reprogram the ECM as you showed. With the BCM still
Work or no?
I'd suggest doing the ECM/VCM/PCM (acronyms de jure) type module first as that's the primary controller in the vehicle, and then doing the BCM second. But I've never read that's a requirement, just seems like the more drama free path imo. If it's a brand new or OEM remanufactured BCM you should be able to do the setup with the Tech2 independently of the ECM. If it's an used BCM, well these older ones you can't update VIN or the mileage or odometer values (I did another video in this bench harness series on these BCM issues)
great video lot of good info, question.. how would you do this without a tech 2 or without the tech line terminal pc ... Is it possible to us Carprog or other device like iprog to change the vin
No idea, I only use GM dealer grade tooling for this sort of thing to avoid drama.
@@DrShock do have any video explain what gm clone tools work, or you used for programing modules on 2015 and newer veclical

Hey Doctor. Im purchasing a ecu from a friend with a tune on it for specific parts for my corvette. Is there a way to change the vin to mine without erasing whats on the ecu? Thanks
I'm not 100% sure as I only use the GM tooling. But the GM scan tools are going to remove any third party tunes as best I can recall, as those are not GM approved calibration files. I'd suggest you'll want to either let the GM tool reset the calibration and revise the VIN then separately re-apply the tune with the third party tooling. Or use a third party tool that will also support updating the VIN.
Hey so just to be clear you can use and rewrite a salvage PCM but if during the calibration something goes wrong and can’t finish the update then you’re SOL?
If something were to go _wrong_ like say a power failure during the calibration update then yes, you can brick the module. The GM PCMs are fairly robust though, so it would have to be something catastrophic like that to brick one. The TIS2Web/Techline Connect software won't let you install an incorrect calibration for the PCM part number and VIN, so that part you're protected from.
I'm About to do my first flash ever on an 06 cobalt...getting a used pcm, I have a cardaq 3 plus...this process the same?
It won't be the same as the Cardaq is not a Tech2 and is not compatible with the older GM TIS2000 software I showed here. But you should be able to use it with a ACDelco TIS2Web subscription as a J2534 device. You won't have the off board programming adapter option as that's not supported by J2534 tools, but you can still update the VIN using SPS.
So you can do a ecm swap in vechical. Do you need tech 2 scanner after.
Of course you can do it in the vehicle, and yes you will have to have access to either a Tech2 or MDI scanner to reset the VIN
Just don’t want it to be worthless because I see tons of older gm vehicles on the road here
I would like to know if you have used the tis2000 in isuzu vehicles? I have the tis2000 but I could not install a used ecu to isuzu 2002 axiom when I write thevin number tells me that it does not exist, maybe that car is not in the tis2000 database?
I have not, only classic GM brands. But you are on the right path, you have to have the Isuzu unique firmware version PCMCIA card plugged into the Tech2 itself, and Global TIS on the PC. The typical TIS2000 DVD is only for North American GM brands. If you search here on YT there's at least one video on how to install GlobalTIS for Isuzu vehicles. Typically when you buy a Tech2 Chinese clone you have to specify these so they include the right versions. There were different Tech2 firmware cards, and TIS DVDs for Saab, Isuzu, Holden, etc.
Hello, I have a authentic tech2 and tis2000 loaded on a tough book with a Bosch Mastertech J box. I have successfully programmed several modules (on vehicle ) on various gm vehicles . I have been trying to bench program instrument clusters without any luck . I’m trying th change programming on the microprocessor. I have a programmer to change the bin file on the eeprom. I have a simulator with a ecm , bcm and Vci. It keeps saying install new IPC. Any thoughts?
I haven't attempted to do an IPC on the bench myself. I presume you're trying to do SPS from within TIS2000 then for an IPC? Be sure you select the Off Board Programming Adapter (OBPA) and not Vehicle when prompted in TIS2000 would be all I could suggest (even if you don't actually have one of these ultra rare tools in the bench setup). In my own experience that selection was necessary to relax some of the SPS checks before I could program a PCM on the bench outside of an actual vehicle. I suspect that the Tech2 and SPS do some checks that require more than the PCM and BCM on the bus as I've had to select OBPA even with both to have any success.
@@DrShock Thank you for you help, I was able to change the ecm and bcm programming to a different year and vin number but not the IPC.
I do know that tis to web does not allow any bench programming. They told me that directly.
I work for a used car dealership and we have a subscription. I will follow your advice and see if it work with my tis2000. Thanks again. I greatly appreciate your help.
Is there a way to communicate with the p11 ecm in standalone harness? Or do I need to wire in the bcm to communicate with the ecm?
The Tech2 is going to want to see the BCM in the circuit. If you're using another aftermarket type tuner tool you may be able to get by with the PCM all by itself though. Haven't personally tried either, so couldn't advise further.
i have a 95 silverado diesel 6.5 TD can I reflash to delete the egr valve?
The GM SPS software doesn't let you customize or make modifications (aka tuning) from how the vehicle was originally built. But it would cover a case where you pulled a donor PCM from a vehicle that had this valve and needed to put it on one that did not since the PCM part numbers are the same. What would control that is the VIN, and the TIS2000 database has all the VINs built to offer up a calibration that is correct. So you could reflash that donor PCM to one without the valve if the VIN called for it. Hope that helps, basically the net net is no you cannot delete the egr valve with SPS if it was original to the VIN. But you can account for it if it was original to the VIN when replacing the PCM.
I want to recreate what you are doing--where should I get the TIS 2000 and do I need an older computer? Thanks if you got the time
You would have to get TIS2000 when you buy a Chinese clone of the GM Tech2 scan tool (they're bundled together). It only runs on Windows 2000 or XP so you'll need a museum piece, or put it into a VM on Windows 10. You can usually find these on ebay ebay.to/2FLoIjI
@@DrShock Thanks
So the dvd version of tis2000 requires no fees? It’s just the latest version of tis? Thinking of buying a tis2000 version on a laptop on eBay
TIS2000 was discontinued towards GM at the end of 2007. So as long as your vehicle is older than 2008 it's an inexpensive solution when paired with a Tech2 scan tool. But for any vehicle newer, it's not going to be of use. You'll have to subscribe to TIS2Web, the replacement on www.acdelcotds.com where GM charges you by VIN. If the vehicle is newer than say 2010 you'll also need to step up to an MDI tool instead of the Tech2 as well.
i have a tech2 that i use on my saab. do you know if a 2008 saturn vue is one the gm 32mb pcmcia card?
The Saturn models are _different_ in alot of ways and I've had viewers comment, for example, that they don't show up at all on TIS2Web applications. You'll want to just power on your Tech2 and _build the car_ and see what options you get given after picking 2008 and Saturn under diagnostics.
DrShock ok so there is an option. Thank you very much
Hi
What is the best tool to scan and reprogramming most cars ? I mean 1 tool if possible
For one tool to rule them all, only the ThinkTool Pro. All car brands in one type bi-directional scanner and reprogramming tools are professional shop grade, and are not going to be cheap due to having to handle multiple OEM proprietary capabilities.
Why would you need to replace or reflash a PCM? what problems do they cause when they go bad?
GM occasionally finds bugs in the firmware of these modules, which can affect drivability, fuel economy, or compatibility with other modules on the vehicle. But the primary reason relating to the video, is you have to reprogram the PCM in order to change the embedded VIN so you can use a salvage yard one for a repair in a different vehicle than the donor.
Does this give power to your car stereo I drive a 2002se Pontiac Sunfire I can't get my stereo to work and my door lights don't come on now I changed the fuse and still nothing works I don't really run a wire from my battery in to the car
O ya one more thing I bought a quick tuner performance Chip it's made for my car are there safe to use and I bought e3 diamond spark plugs to
No, the PCM does not power the radio. The power is wired directly into the radio as part of its wiring harness. If neither the radio nor the interior lights have _any_ signs of power on, and there are no bad fuses, then that points to an interior wiring harness problem that will have to be diagnosed manually. May just be a bad ground due to corrosion but you have to trace the circuit out by hand to find it either way.
I don't have any experience using either of these aftermarket products so couldn't comment.
Hi Dr. Shock, I accidentally reverted the GM 33.004 software on my Tech2 to an earlier version, 27.010, by using the download software function on Tis2000. I managed to find the GM 33.004.bin file on the Internet. Is there anyway I can use TIS2000 to download it back on my Tech2 (memory card)? Thanks.
No, as you've learned TIS2000 only comes with a very old obsolete version. You would have to go to www.acdelcotds.com to download the latest Tech2 firmware, but it'll cost you well over $200 to do so.
Cheaper to find an used memory card on eBay with the right version, or track down the old card_writer.exe utility that could do so from a PC with the appropriate PCMCIA adapter.
@@DrShock thanks so much for the reply. what error message appears when GM prevents you from flashing the same calibration number onto the ECM? my SPS programming fails at around 80% with error message "Utility 12608523 Line 18 Operation B0 Errorcode 85". I'm almost positive that no double flashing of the same calibration number is the cause. At around 9:20 timeline, you mention about a tuning tool that goes in and just changes the VIN on a ECM. Do you mean like EEPROM stuff? Could you leave a link to such tuning tool? Thanks so much for what you do.
I've never seen such an error from a Tech2. But it's definitely not the message for a calibration overwrite, that one would be in plain English. This message looks more like a hardware problem. Either internal to the Tech2, or with the module itself.
The tool I mentioned would be aftermarket to alter factory calibrations. I don't have a particular link as I do not use such tools, and they are not cheap, but _EFILive_ is the one I had in mind when making the comment you reference.
How would you approach a vehicle with a salvaged engine and brand new ECM... without knowing the vin of where the motor came from?
For a brand new ECM/PCM you would have to go the scan tool route with GMs SPS2 subscription (J2534 type tool). More than the VIN has to be encoded onto a virgin module, it needs what GM calls a _calibration_ as well. The scan tool will program it with the VIN of the vehicle it's installed into. So where the salvage engine came from would be irrelevant in this case you describe, where one has a brand new or OEM remanufactured module.
@@DrShock 🧁Sweet! This sounds like pretty good odds to get this thing running! I need a J2534... do I need a special battery charger made for re'flashing? And an SPS2 subscription from AcdelcoTds for $45? Which J2534 do you recommend: EL-52100-AM?
This sounds like some awesome equipment to help out friends and make some extra bucks!
Yeah, the only source for SPS2 is direct from GM at www.acdelcotds.com and they sell subscription by VIN. You would need a battery maintainer, not a charger, especially if it's a newer vehicle with other modules that could be drawing power. For a very old vehicle, like from the 1990s, this is less of a concern as there's usually only the one powertrain control module there.
If I replace it on a 2005 gmc envoy it has to be reflashed cuz it does do anything.
You have to reflash to get the correct VIN and powertrain configuration as the same PCM would be used across multiple vehicle configs.
Hi. what if I cant Contact to the old ECM because there is no Check Engine light in the dashboard in key position 2
what I need to flash the new ECM ( GMC Terrain 2013)
It may be that the bulb is burnt out for the check engine position, there is certainly one on all GMs. 2013 would be far too new for this video to apply. You would need the GM MDI scan tool instead. This video may help for what's involved there - ruclips.net/video/sUMJFwMuAkE/видео.html
@@DrShockThank you for your help
but if the bulb burnt out why I cant scan the ECM at all
If you're using a Tech2, it will not support many 2013 vehicles even with a CANdi module attached. If you're using a non-GM scan tool I wouldn't know as I don't use those. Here's a good reference link on the GM tools, you can see the GMC Terrain started being supported by the MDI tool in 2010 - www.genuinegmparts.com/pdf/positionstatements/vehicles-supported-by-GM-scan-tools-reference.pdf Of course, there's also the possibility you have some damage to the wiring preventing communication, but I would suspect a tool mismatch first.
Anything special needed o a 2004 Bi-Fuel? I have ordered 2 and neither of them activated the natural gas system
I presume you're referring to the 2.2L Ecotec with compressed natural gas (CNG) as an alternative fuel. As best I recall it's the same PCM part number, but the programming is very likely different. So you have to be sure someone is using a genuine GM Tech2 scan tool to program from the GM VIN online database (not just editing the VIN digits with an aftermarket tool) to get the correct CNG calibrations flashed.
@@DrShock Thank you! Is this something you can do?
Any local shop that specializes in ECMs should be able to handle that. Certainly the local GM dealer, though that will be the most expensive option.
@@DrShock lol! Our local dealer 🃏 I will look around but in a pretty small town and no one knows these cars anymore. That is why I am online.
I didn't mean for any repair, just the reprogramming the already installed PCM dealership wise. Definitely you're not going to find any tech's there familiar with these older vehicles. btw, I would expect the original CNG fuel cylinder from GM to have expired from 2004, so you might check that also as a safety consideration.
i have a tech2 and need to clone a pcm of a 2004 cadi cts. i have captured the data of the pcm on the car. then when i go to the tis2000 it states in the bottom right corner of the tis program SAAB. now i generlly use the tech2 on my saab. not sure how to switch it to gm. or do i use this in pass through mode?
You need a different firmware card plugged into the base of the Tech2. The SaaB one is unique for that European model (typically version 148.00). For a Cadillac you need the NAO (North American Operations) one version 33.004. For TIS2000 you can use remote mode or pass thru, doesn't matter. In the video I only show pass thru and here's another on that mode ruclips.net/video/53fho7l7yxI/видео.html, but this other video shows remote - ruclips.net/video/Nr_eYexAAV4/видео.html
@@DrShock I have the card for gm. I now have nano but when I go to install it wants to uninstall my current version with Saab installed. Any recommendations.
@@fatguyfriday Not sure I'm following your _uninstall_ comment. You swapped the PCMCIA cards in the Tech2 and powered back up and it's not just showing the boot screen for the NAO 33.004 firmware? You might want to also check in TIS2000 that under the Configuration menu, Options that the tab for _Dealership_ is set to NAO as well.
@@DrShock cards are fine. It’s the tis2000. Tis2000 is set up for Saab. I put in the tis2000 gm do set up. And it will only give me uninstall as a option. I need to add the gm.
@@fatguyfriday Ah got it. I haven't had to do SPS with a different PCMCIA card so never hit this. For just diagnostics it's all contained within the Tech2 itself. A little google fu and it appears Saab had a unique version of TIS (sometimes referenced as TIS2008-2 in forums) and is not the same as the TIS2000 we use for NAO on the USA vehicles. So yeah it does look like you have to uninstall the other to install the Cadillac compatible one. Gotta remember these programs were only used by GM dealers, and so a Saab dealer wouldn't typically ever see a Cadillac for warranty service. If you google around for TIS2008-2 Saab you'll see some posts around this.
Hi......can this operation done with gm mdi or only by tech2 ....thanks
Both would work fine, but if you use the MDI it will of course cost more $$ as you would have to have a subscription to GM SPS programming at www.acdelcotds.com
@@DrShock thank you
what about the 2002 cavalier???? Can you please make a video!!! I cant find my PCM module anywhere!!! Thanks
If I recall correctly, for 2002 you'll find the PCM inside the passenger side wheel well. Remove the plastic shield behind the strut area and you should see it.
@@DrShock Id have to take off my tire, what a stupid place to put it lol. I also havent been able to even find a new one already programmed in Canada or the US that would ship to me. Do you know anywhere that has one that would ship one to me already programmed? Thank you
These J body BCMs were not typically suitable to remanufacturing (the memory could only be written to once, and not reprogrammed using the typical GM scan tool at the dealership.
So you would have had to buy a new BCM and have it programmed after installation into the vehicle. Or you would have to find a source where they have gone in and _virginized_ the memory to make an used one look new again. I'm not aware of anyone doing this for J-cars currently, so a new replacement from GM is probably the only option here.
Dr. shock I was trying to reprogram a ECU and it said E682: No ECU data available !! what does that mean?
TIS2000 or Techline Connect?
@@DrShock It is TIS2000
That's a rather rare error, and I've not come across it myself. But I would suspect, since it's TIS2000, that it may have to deal with either the security dongle setup (USB or parallel port plug device) or the communications cable between the PC and the Tech2.
Do you offer your service for this ? If so I can send you one. Or once I find the pin no. and communicate this to you could you tell me the value of the bad resistor/capacitor and its location ? I of course would pay for the info. Thanks.
No, I am not a business. But there are folks out there who will do mail in programming of modules. These particular GM PCMs are not repairable as there are no circuit schematics published for them.
You'll have to replace it with either a new, remanufactured, or salvage yard unit.
Will this work for saab modules too if I need to replace them?
I don't know about non-USA vehicles, but if you review the menus in TIS2000 and the Tech2 and they look like what I've shown in the video, then it's likely the same procedure.
Can I pay you to reprogram my chevy silverado 07 ?
Sorry, not a business. But there are businesses that will do this kind of mail in service that you can google for.
Don’t wiggle it too much, or you’ll bend the driver, power, and ground pins.
So you need a power supply, an OEM Delco radio, a Tech 2 GM diagnostic PDA, a laptop, and a few wire adapters to program the engine computer yourself on a bench??? I was hoping to somehow wire my power supply to the engine computer’s power pins, jerry-rigging certain wires from the engine computer to a serial port on a laptop. And some software to program the computer???
Sounds expensive; but then again.... GM engineers are evil, and they only seek to take your money, by charging you an arm and a leg for a part; and then a separate charge for your nut-sack, for the VIN flash to the new computer!!!!
I was able to use my Sega 32X on my Sega Mega-Drive/CD console by doing just that; because I couldn’t find the original video cable for the 32X system back in the day.
