A Note From Our Technicians: Why VIN-Programming is Non-Negotiable
For these ’97 GM vehicles, simply grabbing a used computer from a salvage yard is a recipe for frustration. The PCM is not just a simple component; it’s programmed with specific data for the original vehicle’s engine, transmission, and options. Using a non-programmed unit can lead to incorrect shift points, poor fuel management, and security system conflicts (like GM’s VATS) that can prevent the vehicle from starting at all. Our process of programming this 1997 GMC 1500 PCM 16229684 to your exact VIN ensures all systems communicate correctly, just as the factory intended.
Frequently Asked Questions
What information do you need from me after I order?

How do I know if my PCM is definitely the problem?
Common signs include a check engine light with communication error codes, intermittent stalling, harsh shifting, and unexplained poor engine performance. While these are strong indicators, we always recommend a proper diagnosis by a qualified technician to confirm the PCM is the point of failure before ordering.
