Guided Installation to Restore Peace of Mind
Replacing your PCM is a straightforward job you can confidently tackle in your own driveway. Follow these simple steps to get your truck running perfectly again.
- Safety First: Begin by disconnecting the negative terminal on your vehicle’s battery to prevent any electrical shorts.
- Locate the Old Module: On most 2004-2006 Canyon and Colorado models, the PCM is located on the right-hand (passenger) side of the firewall in the engine bay.
- Disconnect and Remove: Carefully unplug the wiring harness connectors. They have locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket and remove it.
- Install the New PCM: Mount your new, pre-programmed module in the same location. Securely plug in the wiring harnesses, ensuring the locking tabs click into place.
- Reconnect Power: Reattach the negative battery terminal and tighten it.
- Perform Security Relearn: Your vehicle’s anti-theft system needs to sync with the new PCM. This is simple: Turn the key to the ‘ON’ position (without starting the engine) for 10-12 minutes. The ‘Security’ light should turn off. Turn the key off for 10 seconds, then start the engine. Your truck is now ready to drive!

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as each module is uniquely programmed for your specific vehicle.
Is this module truly “plug and play”?
Almost! It comes fully programmed for your engine and transmission. The only additional step required after installation is a simple security relearn procedure, which you can do yourself in about 15 minutes with just your car key. We include easy-to-follow instructions for this process.
Will this fix my exact problem?
This PCM will resolve any issue directly caused by a faulty module. If your vehicle exhibits symptoms like multiple unrelated trouble codes, communication errors (U-codes), or intermittent stalling after all other potential causes (sensors, wiring) have been checked, a failing PCM is the most likely culprit.
Where is the PCM located on my 2005 Canyon?
For the 2004-2006 GMC Canyon and Chevy Colorado, the Powertrain Control Module (PCM) is mounted to the firewall on the passenger side of the engine compartment.
Do I need to send my old PCM back?
No core charge or return is required for this part. You can recycle your old module locally at your convenience.
