Restore Your Truck’s Performance and Reliability
Is your 2004-2006 GMC Canyon or Colorado suddenly stalling, running rough, or refusing to start? A failing Powertrain Control Module (PCM) is often the culprit behind these frustrating and unpredictable issues. Don’t let a faulty computer keep your dependable truck sidelined. This replacement PCM is the straightforward, reliable solution to get you back on the road and back to work with confidence. We handle the complex part by programming the module specifically to your truck’s Vehicle Identification Number (VIN), ensuring a seamless and effective repair.
Common Symptoms & Your Solution
A failing engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, this pre-programmed PCM is your definitive fix:
- Check Engine Light (CEL) with communication-related codes (U-codes) or multiple, unrelated sensor codes.
- No-Start or Hard-Start Condition: The engine cranks but won’t fire up, or takes an excessive amount of time to start.
- Engine Stalling: The engine shuts off unexpectedly while driving or idling.
- Poor Fuel Economy: A sudden and unexplained drop in your truck’s MPG.
- Erratic Transmission Shifting: The PCM controls transmission behavior, and a fault can cause harsh or incorrect shifts.
By installing our 2004-2006 GMC Canyon PCM programmed to your vehicle, you’re not just replacing a part; you’re restoring the central nervous system of your truck with the latest GM software updates for optimal performance.

Expert Mechanic’s Insight: The Critical Role of VIN Programming
As a technician, I’ve seen countless vehicle owners waste time and money on junkyard computers. Here’s the problem: a PCM isn’t just a simple box. It’s specifically coded to the original vehicle’s VIN, options, and anti-theft system (Passlock/VATS). Simply swapping a used one will almost always result in a no-start condition. Our process eliminates that entire headache. We take your VIN, access the correct GM calibration files, and flash the module so it’s a perfect electronic match for your truck. This professional programming is the key to a successful, lasting repair.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the module to function in your truck.
Is any additional programming required after installation?
No. This 2004-2006 GMC Canyon PCM programmed unit is designed to be a plug-and-drive solution. In some cases, a simple crankshaft variation relearn procedure may be needed, which can be done with a capable scan tool or by following a specific driving cycle. However, no dealership visit is required for programming.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM, then yes, this part will resolve the issue. It’s crucial to ensure you have properly diagnosed the problem and ruled out other potential causes like faulty sensors or wiring before ordering.
Where is the PCM located on my 2004-2006 Canyon/Colorado?
On the GMC Canyon, Chevrolet Colorado, and Hummer H3, the Electronic Control Module (PCM/ECM) is typically located on the right-hand (passenger) side of the firewall in the engine bay.
Does this fit other GM vehicles besides the Canyon?
Yes. This module is compatible with a wide range of 2004-2006 GM trucks and SUVs, including the Chevrolet Colorado, Hummer H3, Isuzu I-series, Trailblazer, and Envoy, among others. Please check the compatibility list in the description to confirm it fits your specific vehicle.
