Is Your GM Vehicle Running Rough, Stalling, or Showing a Check Engine Light?
If you’re dealing with frustrating engine performance issues, unpredictable stalling, or a persistent check engine light, the problem may lie with the brain of your vehicle: the Powertrain Control Module (PCM). This critical component, also known as the Electronic Control Module (ECM), manages everything from fuel injection and ignition timing to transmission shifting and emissions control. When it fails, it can cause a cascade of problems that are often difficult to diagnose, leading to wasted time and money on unnecessary repairs.
Symptoms of a Failing Powertrain Control Module
A failing PCM can manifest in various ways, often mimicking other sensor or component failures. If you’re experiencing any of the following, it’s time to consider your engine computer as the potential culprit:
- ✔ Persistent Check Engine Light (CEL) with communication-related trouble codes (e.g., U-codes).
- ✔ Engine stalling or cutting out for no apparent reason.
- ✔ Rough or erratic idling.
- ✔ Noticeable decrease in fuel economy.
- ✔ Engine hesitation or misfires during acceleration.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ The vehicle won’t start at all, despite having a good battery and starter.
- ✔ Intermittent issues with cooling fans or other electronically controlled components.

Instructions for this procedure are widely available for your specific model.
Frequently Asked Questions
What exactly is a Powertrain Control Module (PCM)?
The PCM is your vehicle’s main computer, responsible for managing the engine and transmission. It takes data from dozens of sensors to control fuel delivery, spark timing, and gear shifts to ensure optimal performance, fuel efficiency, and low emissions.
Is this module ready to install when I receive it?
Yes! This module is programmed to the specific VIN you provide at checkout. This means it’s ready for installation right out of the box, with no need for additional dealership programming.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the part to function correctly.
Do I need to perform any other steps after installation?
In many cases, you will need to perform a security relearn procedure to sync the new PCM with your vehicle’s anti-theft system. This is a standard procedure for many GM vehicles and can often be done in your driveway with just the ignition key.
How can I be sure this fits my car?
This module fits a wide range of GM models. Please check the detailed fitment list on this page. The key is to match one of the compatible part numbers (12202600, 12209614, 09360210) with the part number on your original module.
