How to change VIN & PIN in GM ECM/ECU Modules Using The DPS Tool

Great video Troy as always… your tutorial mentions PIN too… does the calibration you’re loading just do away with pin change b/c I didn’t see anything extra for pin changing? 

Hi, thanks. The ECM PIN change process is different from the ECM VIN change process. In the past it was possible to change the VIN and PIN in the other modules except for the ECM via DPS.

You can find more info on the PIN change process for the modules in the video and link below. The PIN change process for the ECM is the same as the other modules, just different DPS codes for the ECM.

This will be great. So 5 byte is only for USA? I have an 2014 Malibu I'm working on for a friend and we're trying to program a used pcm through techline connect and I just found out it's blocked by gm now. I used to be able to program used pcm a while back. Also the techline connect software is total shit man. Everytime they update it breaks the program bad. Currently I'm sitting inside the car and can't even get the program to start because it says it's missing updates and it refuses to download them. I'm just tired of gm with this stupid stuff. They can't even get their programming tools correct. I'll have to tell my friend to order a program ecm. I wish I would've seen this before paying gm for a subscription I can't use. Just want to clarify if this works for USA Malibu or just UK?

It works on both the USA and UK Malibu. At the moment, it only works for 2-Byte seed ECM, and not for 5-Byte ECM. I find when TLC has issues, I use the control panel to uninstall all the GM and bosh applications and then reinstall TLC.

ok ill give your files a go very soon to try out. but man everytime that tlc program updates it breaks something. this on on the latest windows 10 with only tlc installed and nothing else. i was fooling with it in the heat and fighting mosquitos and weird bugs outside. i had gave up because i love to give my children time everyday and just told my friend to order a programmed pcm. he just wantes the car to be able to move since someone stole his pcm. i had gm to refund me my money for wasted time. im always programming malibus so ill be purchasing from you very soon.

Yep, here in England, in a place called Birmingham, a lot of people are getting their car bonnets and front bumpers stolen. One lady went to a concert, and on returning, her car bonnet and bumper were gone. It's kind of weird what's going on. They blame it on the Corona virus🙂

@Troy thanks. Is there any software you have that can do this?

No, I don't have a solution.
