Expert Insight: The Critical Role of VIN Programming
Many people wonder why they can’t just swap a used PCM from another vehicle. On modern vehicles like your Cadillac, the PCM is the central hub of a complex network. It’s tied directly to your vehicle’s anti-theft system (VATS/Passlock) and calibrated for the specific options your car came with. Simply installing a non-programmed unit will result in a no-start condition. Our VIN programming service handles this critical step for you, synchronizing the module to your exact vehicle before it even leaves our facility. This is the secret to a successful, hassle-free repair.
