An Expert’s Note on Programming
“Many owners try to save a few dollars by grabbing a used computer from a salvage yard, only to find their truck still won’t start. That’s because on these GM vehicles, the PCM is electronically tied to the original truck’s anti-theft system (VATS/Passlock). Without proper VIN programming, the module won’t recognize your keys and will prevent the engine from running. Our service eliminates that entire headache. We program the module to your specific VIN, so it communicates perfectly with your truck’s existing components right out of the box.”
Getting your truck back to peak condition is simple. After purchase, just send us your vehicle’s VIN, and our technicians will handle the rest. We’ll meticulously program the module, verify its function, and ship you a part that’s ready for installation. This is the ideal 2004-2006 GMC Canyon PCM replacement for both seasoned DIY mechanics and first-timers.
Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM arrives fully programmed to the VIN you provide after your purchase. The only step you may need to perform is a simple security relearn procedure, which involves a few cycles of the ignition key and takes about 30 minutes. We include clear instructions for this process.
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 in your vehicle.
How do I know if this is the right part for my truck?
This module fits 2004-2006 GMC Canyon, Chevy Colorado, and several other GM models listed in the fitment guide. The best way to confirm is to match the part number on your existing module to one of the numbers in our list. If you’re unsure, contact us with your VIN, and we’ll be happy to verify compatibility for you.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM (common codes include P0601-P0606), then this 2004-2006 GMC Canyon PCM replacement will solve the problem. However, it’s crucial to ensure your vehicle has been properly diagnosed, as a check engine light can be caused by many other components like sensors or wiring.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. This covers any issues related to the function of the module itself. If the unit fails within one year of the purchase date, we will provide a replacement.
