Is it possible to change the vin in the rear diff module. Its a 2018 Chevy equinox. I tried reading the module with DPS but it don't read. Maybe i'm using the wrong address. Anyone have a list of gm ecu address

Possibly  ecu adress 1B

Or 1A

Check diagnostic address in GDS2.

i think gds does'n support equinox 

I'll try those addresses. I think GDS said K47 for rear diff. It never read the module using that. I'll try 1A and 1B

2018 should be a third gen already - these are definitely supported! Must use adequately fresh deliverables, of course.
Equinoxes are supported in GDS2 starting with 2nd gen 2010MY. Must use Tech2 for first gen only.
