A Mechanic’s Perspective: I’ve seen countless 90s-era GM trucks and vans sidelined by a bad computer. The owners often think it’s a major mechanical failure. A customer brought in his ’97 Savana work van that two other shops couldn’t diagnoseโit would randomly stall in traffic. We identified the faulty computer, and instead of a costly dealer part, we installed one of our pre-programmed units. The van was back in service the same afternoon, running more smoothly than it had in years. This 1997 GM PCM 16229684 is the key to getting these dependable workhorses back on the job.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
Simply enter your 17-digit Vehicle Identification Number (VIN) in the notes section during checkout. If you forget, we will contact you via email after your purchase to retrieve it. We cannot ship your module until we have your VIN to program it correctly.
Is this a simple plug-and-play installation?
Yes, for most vehicles. Because the module comes programmed to your VIN, you can typically install it and start your vehicle. On some models, a straightforward security relearn procedure (often called a CASE relearn) may be necessary, which can be done without special tools. Instructions are widely available online for this simple process.
Do I need to send my old PCM (core) back?
No. There is no core charge or requirement to return your old module, saving you time and return shipping costs.
How do I know for sure that my PCM is the problem?
While the symptoms listed are strong indicators of a failing PCM, we always recommend a proper diagnosis by a qualified mechanic. Common signs include internal fault codes (like P0601-P0606), no communication with scan tools, or having ruled out all other possible causes like sensors or wiring.
Will this fix my check engine light?
If your check engine light is caused by an internal failure of the original PCM, this replacement module will resolve the issue. After installation, it’s always a good practice to clear all codes with a standard OBDII scanner to allow the system to reset.
Which vehicles is this 1997 GM PCM 16229684 compatible with?
This module fits a wide range of 1997 GM vehicles, including the Chevrolet Express, Savana, Suburban, Tahoe, S10, and various pickups, as well as the GMC Yukon, Safari, Jimmy, and Sonoma. Please refer to the full fitment list on this page to confirm compatibility with your specific model and engine.
