Have you tried re-programming the VID?

>>
P0602 - Control Module Programming Error

This Diagnostic Trouble Code (DTC) indicates programming error within Vehicle ID block (VID).

VID data corrupted by the scan tool during VID reprogramming

Using the scan tool, reprogram the VID block. If PCM does not allow reprogramming of the VID block, reflashing PCM will be required.
