Restore Peak Performance to Your 1997 GM Vehicle
Is your 1997 Chevrolet, GMC, or Isuzu truck, van, or SUV running rough, stalling, or refusing to start? Are you battling a persistent Check Engine Light with confusing error codes? The issue often points to a failing Powertrain Control Module (PCM), the central computer of your vehicle. This replacement Engine Control Module, part number 16229684, is the definitive solution to get your vehicle back on the road, running smoothly and reliably. It’s not just a part; it’s a complete, programmed solution tailored specifically for your vehicle.
The PCM is the brain of your engine and transmission, controlling critical functions like fuel mixture, ignition timing, and transmission shift points. When it fails, it can cause a wide array of frustrating and difficult-to-diagnose problems. Our service eliminates the guesswork and the expensive trip to the dealership. We flash this module with the latest official GM software updates using the Vehicle Identification Number (VIN) you provide. This ensures perfect compatibility and optimal performance, just as the manufacturer intended.
From the Diagnostic Bay
We had a 1997 Chevy C1500 towed in that had its owner chasing his tail for weeks. The truck would start fine cold, but after 15 minutes of driving, it would start to sputter, misfire, and eventually stall. The owner had already replaced the fuel pump, filter, plugs, and wires. He was convinced it was a fuel pressure issue. When we hooked up our scanner, we noticed the fuel injector pulse width was erratic as the engine warmed up. Instead of a mechanical fault, the PCM’s internal driver for the injectors was failing under heat. We installed a VIN-programmed module just like this one, and the truck ran perfectly. It’s a classic case where the root cause is electronic, not mechanical, saving the customer from replacing more unnecessary parts.
Diagnosing a Faulty 1997 GM Truck PCM
A failing engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a faulty PCM could be the culprit. This replacement module is designed to correct these issues and restore your vehicle’s factory operation.
- ✔ Check Engine Light: The light is on, and you may have codes related to sensors, misfires, or internal module failure.
- ✔ No-Start or Hard-Start: The engine cranks but won’t start, or takes an excessive amount of time to fire up.
- ✔ Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, or rough idling.
- ✔ Reduced Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG.
- ✔ Erratic Shifting: The automatic transmission may shift harshly, late, or not at all.
- ✔ Intermittent Stalling: The engine dies for no apparent reason, either while driving or at a stop.
- ✔ Failed Emissions Test: Inability to pass state emissions testing due to engine performance or communication errors.

Our technicians then program this PCM with the exact software and calibrations for your specific make, model, and engine. This makes installation a direct, plug-and-play process for you or your mechanic. This specific 1997 GM Truck PCM is a direct replacement for part number 16229684 and alternate part number 8162296840.

Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the module to function in your vehicle.
Is any additional programming required after installation?
In most cases, no. This 1997 GM Truck PCM comes fully programmed and ready for installation. However, some vehicles may require a security relearn procedure (often called a CASE relearn or Passlock relearn), which can typically be done without special tools. Instructions for this simple procedure are widely available online or in service manuals.
Where is this module located on my vehicle?
For the majority of the compatible models, the PCM is located in the engine bay, on the driver’s side, near the battery or firewall. It is a silver metal box with multiple large electrical connectors.
What if my original part number is slightly different?
This module is a direct replacement for part number 16229684 and its alternative, 8162296840. If your original module has a different number, please contact us with your VIN to verify compatibility before ordering to ensure you receive the correct part.
Do I need to send my old PCM back?
This listing does not require you to return your original module (core). You can keep your old part or dispose of it responsibly.
