I have a 2014 Caprice that I did a 6.2 swap into. The car was a roller and ended up using the PCM from the Escalade the 6.2 came from as the car didn?t have one. As of now, I?m getting a service anti theft message and have a no crank issue. Once I flash the PCM with the correct vin, would that fix the issue or will I have to change something else in the PCM?
