A Mechanic’s Insight: I once worked on a ’97 Chevy S10 that had its owner stumped for weeks. It had a random misfire that only happened after it was driven for 20 minutes. The owner had replaced plugs, wires, cap, and rotor. The issue was a hairline crack on the PCM’s circuit board that would expand when hot, causing a fault. Swapping in a quality, pre-programmed computer like this 1997 GMC Safari PCM 16229684 solved the problem instantly. Sometimes the most frustrating issues have the simplest solution if you target the right component.
Frequently Asked Questions
What do I need to do after I purchase this PCM?
After placing your order, you MUST provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship your module without it. You can typically find your VIN on your vehicle’s dashboard (driver’s side), the driver’s side door jamb sticker, or on your registration and insurance documents.
Is this module difficult to install?
For most DIYers with basic tools, the installation is straightforward. It is typically located in the engine bay. The most critical step is to disconnect the vehicle’s battery before removing the old PCM and installing the new one. This prevents electrical damage. The unit is designed to be a direct, plug-in replacement.
Will this fix my check engine light?
If your check engine light is on due to an internal failure of your existing PCM (common diagnostic codes include P0601-P0606), then this replacement module will solve the problem. However, if the light is caused by another failing sensor or component on the vehicle, you will still need to address that separate issue.
Is any other programming needed after installation?
No, this module arrives fully programmed and ready to run your engine. However, on some GM vehicles of this era, a simple ‘Security Relearn Procedure’ may be necessary to sync the new PCM with your vehicle’s anti-theft system. This procedure does not require special tools and can be done in your driveway in about 30 minutes. Instructions are readily available online.
Does this fit vehicles other than the 1997 GMC Safari?
Yes, absolutely. This PCM is compatible with a wide array of 1997 GM vehicles, including the Chevy/GMC C/K 1500, 2500, and 3500 pickups, Suburban, Tahoe, Yukon, S10/Sonoma, Blazer/Jimmy, and Astro Van, among others. Please check the detailed fitment list on this page to confirm compatibility.
