Expert Technician’s Note: I’ve seen countless DIYers and even professional shops waste hundreds of dollars chasing phantom sensor codes when the PCM was the root cause. A common mistake is installing a used module from a salvage yard. While it might look identical, it’s programmed for a different vehicle with different options. This creates immediate running problems or a new set of confusing codes. Our process of programming this **2003 GMC Safari PCM** specifically to your VIN isn’t just a convenience—it’s the critical step that guarantees the module communicates correctly with your engine, transmission, and security system, just as it did from the factory.
