Restore Your Truck’s Performance and Reliability
Is your Chevrolet Colorado or GMC Canyon suffering from frustrating issues like a persistent Check Engine Light, rough idling, stalling, or a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the brain of your vehicle’s engine and transmission. Don’t let a faulty computer keep your truck sidelined. This professionally programmed PCM is the definitive solution to get you back on the road with confidence and restored performance.
Common Symptoms & Your Solution
A failing engine computer can cause a wide range of problems that are often misdiagnosed. If you’re experiencing any of the following, a faulty module is the likely culprit:
- Persistent Check Engine Light (CEL) with codes like P0601, P0602, P0606, or other communication errors.
- Engine Stalling or Quitting unexpectedly while driving or at a stop.
- Rough or Erratic Idle that you can’t seem to solve with other repairs.
- Poor Fuel Economy and a noticeable drop in engine power.
- Failed Emissions Test due to module-related errors.
- No-Start Condition where the engine cranks but will not fire up.

An Expert’s Note on VIN Programming
Back in the day, you could often swap computers between similar vehicles. That’s no longer the case. On modern trucks like your Colorado, the PCM is the central hub that talks to everything—the instrument cluster, the anti-lock brakes, the body control module, and the anti-theft system. Programming it to your specific VIN isn’t just a suggestion; it’s essential. It ensures all the components work together seamlessly and that the anti-theft system recognizes the new module, allowing your truck to start and run correctly. We handle this critical step for you, so you receive a part that’s truly ready for your vehicle.
Frequently Asked Questions
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your VIN. We cannot ship your part until we receive this information, as the programming is specific to your truck.
Do I need to do anything after installing the PCM?
Yes. You will need to perform a simple security relearn procedure, which typically takes about 30 minutes and involves turning the key on and off in a specific sequence. This allows your vehicle’s anti-theft system to recognize the new computer. We provide clear instructions to guide you through this process.
Is this a brand new part?
This is a high-quality, fully functional component that has been meticulously inspected and tested to meet or exceed original equipment standards. It is then programmed with the latest GM software for your vehicle.
How can I be sure my old PCM is the problem?
While the symptoms listed are strong indicators, it’s always best to have a qualified mechanic perform a full diagnostic. Common trouble codes like P0601 (Internal Control Module Memory Check Sum Error) are a definitive sign of a failed computer. This 2004-2006 Colorado PCM is the correct fix for those codes.
Will this fit other vehicles besides the Colorado?
Yes, this computer fits a wide range of GM trucks and SUVs from this era. Please check the detailed fitment list on this page to confirm it is the correct part for your specific make, model, and engine.
