PCM Programming (USED) - FLASHED WITH TECH 2 & TIS2000

This is a class 2 vehicle so Tech 2 works best. It can still be used with sps2. If you use J2534 you should remove all other modules using the splice pack.

Thanks William. I just program & change VIN with Tech 2 since I have it also.

The programming should change the VIN as well, but yes. You can check in module info on the Tech 2 to make sure.

Thanks William. I did few of them before but its been years now so I just wanted a professionals opinion before I jump in and damage something.

Hi Arsalan, On something like that I would recommend (if you have it, or know someone who does) using TIS2k/TIS2000. After other posts on the problems that have occurred using Techline Connect, I wouldn't even try to attempt what you're asking using the new SPS2. diag​.​net/msg/m54q41i4n5…

About 2 weeks ago, I called and spoke to GM about this problem. Yes, there were indeed some problems with the SPS2 roll out to the aftermarket. At this point the majority of these issues have been repaired.

Hi William, Is this something recently that has been rectified? I know some other GM techs that have gotten to the point that they're not doing programming on GM vehicles prior to … due to the problems with SPS2. I have a 2007 Pontiac G6 and I'm replacing the injectors on this. There's an update for the updated injectors. GM specifically has this message “Important: For Chevrolet and…

Yes, it is recent. I know Opus IVS has given a lot of input to gm recently as they perform a ton of programming. I was on the dealer side and we had some issues as well a while back. Most small shops and mobile guys shutdown when talking to ACDelco as they do no receive a lot of help as they are not using factory equipment like the MDI 2. The way it was explained to me was use wiring diagrams…

Nope. You still can't program the older stuff with used modules. Verified today.

Strange… I have not had an issue. What was the y/m/m? Was it a CAN or Class 2 module? What equipment are you using And are you removing the other modules from the Class 2 network? I only ask as others do not seem to be having the same issues, so there must be something different.

PCM on an '07 SRX. (CAN) I had flashed this car on SPS previously for a TCM. MDI on SPS2. Bricked at 30%. I used my HPT box to fix the bootloader and then flashed it with my TIS2000 VM with no issues.

Thanks. Very interesting that CAN modules are still failing. I will bring this to the attention my ACDelco contact.

Tech2 or MDI. Doesn't matter, really. It will probably fail on SPS2, though and you will need your hand held by ACD if you want to do it through the Tech2 (unless you have the proper driver setup). Easy job with TIS2000.

I use tis2000 and a tech 2 with security access , anything 07-08 you should use the mdi, dont try to program with a clone tech 2 unless you know it works, ive seen bricked ecms with the clones

I replaced a couple of pcm now non gloabal A and had good success with just j2534 box and SPS2 just when SPS pops up wrong vin detected hit the override red button and it will let u change the donor vin to the windshield vin HTH

How do you determine global from non- global? I “ programmed” a used steering module on a 2017 Corvette but VIN could not be changed and code confirms it. A call to GM’s customer service confirmed that since 2010, used modules with global architecture cannot be programmed with the VIN of vehicle it is installed in. This is a vile move by GM and a waste of perfectly good modules. Greed wins over…

Hi manny, yea GM is putting brakes on aftermarket using used modules and what does the consumer do when the module is no longer produced, GMs answer, time to tell consumer to buy a new car, I guess that’s where eeprom work comes in . At the AC Delco site they have a list of all global vehicles. In America it started in 2010 by year 2014 all Gm vehicles are global A

The term is "Global A". Any car that is not covered by Tech2 is Global A architecture. see attached
