Get Your Dependable GM Truck Back in Action
Is your trusted 1997 Chevy, GMC, or Isuzu truck, van, or SUV suddenly unreliable? If you’re dealing with frustrating issues like a no-start condition, a persistent check engine light, rough idling, or poor fuel mileage, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it’s a problem that sidelines the vehicle you depend on. This pre-programmed PCM is the straightforward, reliable solution to restore your vehicle’s performance and get you back on the road with confidence.
Common Symptoms of a Failing PCM & Your Solution
A faulty engine computer can cause a wide range of confusing symptoms. If your vehicle is experiencing any of the following, our VIN-programmed 1997 GM PCM 16229684 is the definitive fix:
- Check Engine Light: Illumination with communication-related Diagnostic Trouble Codes (DTCs) or false sensor codes.
- No-Start or Hard-Start: The engine cranks but refuses to start, or only starts after extended cranking.
- Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, and decreased fuel economy.
- Erratic Shifting or Stalling: The transmission may shift harshly, or the engine might stall unexpectedly while driving or at idle.
- Intermittent Issues: Problems that appear randomly and are difficult to diagnose, often worsening as the engine warms up.
Instead of struggling with a vehicle that’s lost its dependability, this module provides a direct path to a lasting repair. We take care of the complex programming, so you can focus on the installation.

A Technician’s Insight: I’ve seen countless 1997 GM trucks and SUVs come into the shop with bizarre, hard-to-trace electrical gremlins. The owner has often replaced multiple sensors trying to fix a stalling or shifting problem, with no luck. In so many cases, the root cause is the original PCM finally giving out after decades of heat cycles. The key to a successful repair on these vehicles is the programming. A generic module won’t work correctly. By programming this 1997 GM PCM 16229684 to the VIN, we ensure it communicates properly with the vehicle’s security system (PassLock) and other modules, making the final installation process as smooth as possible.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
Will I need to do any other programming after installation?
In most cases, you will need to perform a simple security relearn procedure after installing the PCM. This procedure can be done without any special tools and typically involves a sequence of turning the key in the ignition. Instructions are widely available online for your specific model.
Where is the PCM located on my 1997 GM vehicle?
On most 1997 GM trucks, vans, and SUVs like the Tahoe, Suburban, and C/K pickups, the PCM is located in the engine compartment on the driver’s side, often near the battery or on the inner fender.
How can I be sure my original PCM is the problem?
While the symptoms listed are strong indicators, it’s always best to have the vehicle properly diagnosed. This includes checking for consistent power and ground at the PCM connector and ensuring there are no wiring issues. A common sign is a lack of communication with a professional scan tool.
