Is Your 1997 GM Vehicle Running Poorly?
If your 1997 Camaro, Firebird, Grand Prix, or another GM vehicle from that era is experiencing frustrating issues like a persistent check engine light, erratic shifting, stalling, or a no-start condition, a failing Powertrain Control Module (PCM) is often the culprit. The PCM is the central computer of your vehicle, managing everything from fuel injection and spark timing to transmission shift points. When it begins to fail, it can cause a cascade of problems that are difficult to diagnose. Don’t let a faulty computer keep you off the road. This direct-fit replacement module is the reliable solution to restore your vehicle’s performance and drivability.
From the Diagnostic Bay
We had a 1997 Pontiac Bonneville SSEi with the supercharged 3.8L come into the shop with a complaint of intermittent stalling at stoplights and a hard-start condition when warm. The owner had already replaced the plugs, wires, and fuel filter with no success. We connected our scanner and found no hard fault codes, only a history of random communication errors with the transmission module. After running a full diagnostic, we monitored the data stream from the PCM and noticed the injector pulse width would randomly drop out for a split second, just enough to cause a stumble or stall. We traced the issue to a failing driver circuit inside the original PCM. We installed one of our VIN-programmed modules, performed the security relearn, and the car ran perfectly. It’s a classic example of how a failing computer can create ghost-like symptoms that frustrate even seasoned mechanics.
Why Choose Our Pre-Programmed 1997 Camaro PCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and high cost out of the equation. When you order, you provide us with your vehicle’s Vehicle Identification Number (VIN). Our technicians then flash the module with the latest, most stable GM-certified software specific to your car’s exact build. This ensures perfect compatibility and optimal performance, right out of the box. You get a fully functional brain for your car without the need for an expensive trip to the dealership for programming.

Simple Installation Process
Installation is straightforward for anyone with basic mechanical skills. After receiving your VIN-programmed module, simply disconnect the battery, locate and remove your old PCM, and install the new one. Once connected and the battery is reconnected, you may need to perform a simple security relearn procedure (often called a CASE relearn). This procedure syncs the new module with your vehicle’s anti-theft system and can typically be done without any special tools. Instructions for this procedure are widely available online or in your vehicle’s service manual.
Frequently Asked Questions
Do I need to have this programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide your vehicle’s VIN during or after checkout, and we will flash the module with the correct GM software for your specific vehicle.
What is a VIN and where can I find it?
The VIN is your Vehicle Identification Number, a unique 17-digit code for your car. You can find it 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 a simple plug-and-play installation?
Yes, for the most part. The module will plug directly into your vehicle’s wiring harness. However, after installation, you will likely need to perform a security relearn procedure to sync the new PCM with your car’s anti-theft system. This can usually be done without special tools by following a specific sequence of key turns.
How can I be sure my PCM is the actual problem?
While the symptoms listed are very common for PCM failure, they can also be caused by other issues. We always recommend a thorough diagnosis by a qualified mechanic to confirm the PCM is the root cause before ordering. Check for consistent power and ground at the PCM connector and rule out sensor or wiring issues first.
What part numbers does this module replace?
This module is a direct replacement for OEM part numbers 16227797 and 19109047.
