I wonder what hex numbers change in the DPS display when you try to program a different VIN.  I also wonder what hex numbers are programed into the module at the factory before the module is installed.  I doubt there is an easy way to dump the flash memory contents to check differences before and after programing. 

I suspect "new" units go through an initial paring routine where the car's VIN in the ECU is written to the module.  I suspect at that point the module flash memory is blank or at least the portion where vin is written is all blank (hex = 00) that causes the ECU vin to be written there for initial paring. 

I am slowly experimenting with these types of things in my spare time.  I find it very interesting how it all works.

The TCM module does not store a VIN number.

Do you know if this will edit Vin on USA Global A Silverado's,

but got donor module to work.

Hi, it’s hard to tell which models it works on as I only have a 2015 insignia/Buick regal car, that’s what I do all my experiments on. 
From members feedback it also works on chevrolet spark LV7 1.4

This is a 3byte seed key file so it may work on cars that has an electric power steering from 2014 to 2017. 
It won’t work on newer cars that has the 5byte seed key. 
However, if it does not work on your car and you can provide the utility file

, I can create the file needed to change the vin in all power steering modules including the newer 5byte versions.

Hi, that car’s power steering is using a different algo. 
Can you private message me a screenshot of the DPS “get controller info” “read info” screen. The ecu id for power steering is 31, and send me the utility file for your power steering. 
Use this tutorial below for getting the utility file for the power steering. 
 

I will need to create a special file for your  steering module

You can use any OBD diagnostic interface that's compatible with GM's SPS service, example Drew tech mongoose pro 2 GM, GM official MDI, or a cheap VXdiag NANO GM.

Many people uses the cheap VXdiag nano GM interface with DPS without any issues, you can find them reasonable priced on Ebay.
