Restore Peak Performance to Your 1997 GM Truck or Van
Is your trusty 1997 GMC, Chevrolet, or Isuzu suffering from perplexing issues like a persistent check engine light, rough idling, poor fuel economy, or even a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your vehicle’s engine and transmission. Don’t let a faulty module keep you off the road. This direct-replacement PCM, part number 16229684, is the definitive solution to get your vehicle running reliably again.
This isn’t just a component off a shelf; it’s a fully integrated solution for your vehicle. Before we ship it, we program the module with the latest GM software updates using the unique Vehicle Identification Number (VIN) from your truck or van. This critical step ensures that the PCM communicates perfectly with your specific engine, transmission, and all related sensors, restoring its original factory performance and efficiency.
From the Diagnostic Bay
We had a ’97 Chevy S10 in the shop that was driving the owner crazy. It had an intermittent stalling problem and a random misfire code (P0300) that no one could solve. They had already replaced the plugs, wires, distributor cap, rotor, and even the fuel pump. The truck would run fine for days, then suddenly die at a stoplight. After hours of diagnostics, we traced the fault to a failing ignition control driver inside the original PCM. It would overheat and momentarily cut spark. Installing a correctly programmed PCM like this one solved the problem instantly. It’s a reminder that sometimes the most elusive issues lead back to the vehicle’s brain.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) illumination
- ✔ Engine stalling or stumbling for no apparent reason
- ✔ Noticeable decrease in fuel mileage
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Failure to pass state emissions testing
- ✔ Engine cranks but refuses to start
- ✔ Communication errors with diagnostic scan tools
Why Choose Our Programmed 1997 GMC 1500 PCM?
The PCM is the heart of your vehicle’s electronic system. It precisely controls fuel injection, ignition timing, transmission shift points, and emissions systems. When it fails, the entire powertrain is affected. Our process eliminates the guesswork and costly dealership programming fees. By providing your VIN during checkout, you receive a module that is ready for installation. This ensures all parameters specific to your vehicle’s original build sheet are loaded, from engine size and transmission type to emissions equipment. It’s the most effective way to ensure a lasting repair.
Installation Note
While this module is a direct physical replacement, your vehicle’s anti-theft system (PassLock/VATS) will require a simple “relearn” procedure after installation to recognize the new PCM. This can typically be done without special tools and involves a series of key cycles. A common procedure is the 30-minute relearn, and instructions are readily available online or in service manuals.

Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s 17-digit VIN when you place your order, and the module will arrive ready for installation and the security relearn procedure.
Where can I find my vehicle’s VIN?
Your VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this part difficult to install?
The physical installation is straightforward for someone with basic mechanical skills. It’s typically located in the engine compartment. The most important step after installation is performing the security relearn procedure, which allows your vehicle’s anti-theft system to sync with the new PCM.
Will this fix my check engine light?
If the check engine light and associated diagnostic codes are caused by a faulty PCM, then this replacement part is the correct solution. It’s always recommended to have the codes read by a scanner to help confirm the diagnosis before ordering.
What part numbers does this module replace?
This module is a direct replacement for original GM part numbers 16229684 and 8162296840. Verifying your original part number is a great way to ensure compatibility.
