Is Your 1997 GM Vehicle Running Poorly?
If you’re experiencing frustrating issues like a persistent check engine light, erratic engine performance, harsh shifting, or even a no-start condition, the problem may lie with the heart of your vehicle’s electronics: the Powertrain Control Module (PCM). As the central computer, the PCM is responsible for managing everything from fuel injection and ignition timing to transmission shift points. When it begins to fail, it can cause a cascade of problems that are often difficult to diagnose.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh, erratic, or delayed automatic transmission shifting.
- ✔ The vehicle fails to start, even with a good battery and starter.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Failure to pass an emissions test.

Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM), often called an ECM or engine computer, is the main computer in your vehicle. It controls all aspects of the engine and transmission to ensure optimal performance, fuel efficiency, and emissions.
Do I need to get this programmed at a dealership?
No. This module comes pre-programmed to your vehicle’s specific VIN before we ship it. This saves you the time, hassle, and high cost of dealership programming. It’s ready to be installed right out of the box.
Is this a plug-and-play part?
Yes, for most vehicles, the installation is a direct swap. You disconnect the battery, remove the old module, install the new one, and reconnect the battery. Some vehicles may require a simple security relearn procedure, which can typically be done without special tools.
How do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on a metal plate on the driver’s side of the dashboard (viewable through the windshield), on the sticker in the driver’s side door jamb, and on your vehicle’s registration and insurance paperwork.
What happens if I provide the wrong VIN?
Providing the correct VIN is critical. An incorrect VIN will result in the wrong software being loaded, and the module will not function correctly in your vehicle. Please double-check your VIN before sending it to us.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM, then this part will resolve the issue. However, the check engine light can be triggered by many other components. It is always best to have the vehicle properly diagnosed to confirm the PCM is the point of failure.
