Restore Your Truck’s Performance and Reliability
Is your GMC Canyon, Chevy Colorado, or Hummer H3 suffering from frustrating issues like a persistent check engine light, rough idling, stalling, or a complete no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your engine’s performance. Instead of dealing with the high costs and programming hassles at a dealership, get the definitive, plug-and-play solution. This module arrives at your door fully programmed to your vehicle’s specific VIN with the latest GM software updates, ready for a straightforward installation that gets you back on the road fast.
Common Symptoms of a Failing PCM & Your Solution
A faulty PCM can cause a wide range of drivability problems that can be difficult to diagnose. If you’re experiencing any of the following, this module is your solution:
- Check Engine Light: Persistent illumination with codes like P0601, P0602, P0606, or other communication errors.
- Engine Performance Issues: Stalling, hesitation, poor acceleration, and a noticeable drop in fuel economy.
- No-Start Condition: The engine cranks but refuses to start, often due to a lack of fuel or spark command from the PCM.
- Harsh or Erratic Shifting: The PCM also controls transmission functions, and failure can lead to incorrect gear changes.
- Communication Errors: Your scan tool is unable to communicate with the PCM.
This pre-programmed 2004-2006 GMC Canyon PCM is the reliable fix for these issues, restoring your vehicle’s factory performance and dependability.

Expert Insight: The End of a Diagnostic Nightmare
We recently worked with a customer whose 2005 Chevy Colorado had an intermittent no-start condition that had stumped two different repair shops. They had replaced the fuel pump and crank sensor, but the problem persisted. The culprit was a P0601 ‘Internal Control Module Memory Check Sum Error’ that only appeared when the truck was warm. This is a tell-tale sign of an internal PCM failure that heat can exacerbate. Instead of chasing phantom wiring issues, they installed our VIN-programmed module. The truck fired up instantly, the code was gone for good, and the owner finally had a reliable vehicle again. Don’t waste time and money on guesswork; the solution is often simpler than you think.
Frequently Asked Questions
Do I need to do any programming myself?
No. This module is a complete plug-and-play solution. We program it using the VIN you provide during checkout, so it’s ready for installation right out of the box. You will, however, need to perform a simple Crankshaft Variation (CASE) relearn procedure after installation, which can be done with most professional-grade scan tools.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will receive an email with simple instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for the programming process.
Is this the correct 2004-2006 GMC Canyon PCM for my truck?
This unit is compatible with the 2004-2006 GMC Canyon and a wide range of other GM trucks and SUVs. Please cross-reference your original part number with the extensive list provided in this listing to confirm an exact match for your vehicle.
What is a CASE Relearn and is it difficult?
A CASE (Crankshaft Angle Sensor Error) Relearn is a procedure that synchronizes the new PCM with your engine’s crankshaft position sensor. This is required to prevent a P1336 trouble code. It is a simple, 5-minute procedure that must be performed with a compatible bi-directional scan tool. Most local repair shops can perform this for a minimal charge if you do not have the required tool.
How does the warranty work?
This unit is backed by our one-year replacement warranty. In the unlikely event of a failure within one year of the purchase date, we will provide a replacement unit. Please contact us for instructions on how to initiate a warranty claim.
