An Expert’s Note on VIN Programming
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used, non-programmed computer. It almost never ends well. On these late-90s GM vehicles, the PCM is tied directly to the anti-theft system (VATS/Passlock). A mismatched module will prevent the car from starting, period. Our VIN programming service not only matches the security information but also loads the correct calibration files for your specific engine, transmission, and emissions equipment. This is the only way to guarantee a proper, lasting fix for a faulty 1998-1999 Oldsmobile Cutlass PCM and similar models.
