Bring Your Dependable GM Truck Back to Life
Is your trusty 1997 Chevy, GMC, or Isuzu truck acting up? Unexplained stalling, a persistent check engine light, or erratic shifting can be incredibly frustrating, especially when you rely on your vehicle day in and day out. Often, the root cause isn’t a bad sensor or a mechanical failure, but the very brain of your truck: the Powertrain Control Module (PCM). This isn’t just a replacement part; it’s the definitive solution to restore the reliable performance you depend on. We professionally program this module to your vehicle’s specific VIN, ensuring it works correctly right out of the box, getting you back on the road with confidence.
Common Symptoms of a Failing GM PCM & Your Solution
A failing PCM can cause a cascade of confusing problems that can be difficult to diagnose. If your truck is experiencing any of the following, a faulty module is the likely culprit:
- Check Engine Light: The light is on, but you’re getting communication error codes (U-codes) or codes for multiple, unrelated sensors.
- No-Start or Hard Starting: The engine cranks but refuses to start, or only starts intermittently.
- Poor Performance: You may notice a sudden drop in fuel economy, rough idling, stalling, or hesitation during acceleration.
- Erratic Transmission Shifting: The transmission may shift harshly, at the wrong times, or not shift at all.
This pre-programmed 1997 Chevrolet 1500 PCM 16229684 is the solution. Instead of paying for expensive diagnostic fees and a new computer at a dealership, you get a fully prepared module that’s ready for installation as soon as it arrives.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before we ship the module. The only thing you may need to do after installation is a simple security relearn procedure, which takes about 30 minutes and does not require any special tools.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this the right part for my 1997 GMC Sierra or Chevy Tahoe?
Yes, most likely. This module fits a very wide range of 1997 GM trucks, vans, and SUVs with gasoline engines, including the Chevy 1500/2500/3500, Suburban, Tahoe, S10, Blazer, and their GMC counterparts. Please check the detailed fitment list on this page to confirm compatibility with your exact model.
How do I know for sure that my original PCM is faulty?
While the symptoms listed above are strong indicators, the best way to be certain is through professional diagnosis. However, common signs of a bad PCM include multiple unrelated trouble codes, communication errors with a scan tool, and having ruled out all other potential causes (like sensors or wiring) for a persistent issue. This 1997 Chevrolet 1500 PCM 16229684 is the final step for many of these hard-to-diagnose problems.
What is the security relearn procedure?
This is a simple procedure that syncs the new PCM with your vehicle’s anti-theft system. It typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating this sequence three times. We include easy-to-follow instructions to guide you through it.
