Hi Troy

 

Which file do i need for BCM vin relearn 3 byte or 5 byte for usa GM?

Thanks

I’ll make a photo showing how to identify 2 byte and 5 byte seed later when I get home. The files I call 3 byte seed is actually 2 byte. This was my mistake in naming files.

I think all GM USA cars it should be 2 byte? when i have a chance i will check and let you know

Thanks

I think the seed byte depends on the age of the car.

Older cars from 2014-2017 uses 2 byte seed. Most 2020 and 2021 cars uses 5 byte seed and some global B cars uses 32 byte seed.
