Frequently Asked Questions
Do I need to do any programming or flashing myself?
Absolutely not. This module is sold as a fully plug-and-play solution. We handle all the programming before it ships. All you need to do is provide us with your vehicle’s VIN during or after checkout.
Where is the PCM located on my 2005 GMC Canyon?
On the 2004-2006 GMC Canyon, Chevrolet Colorado, and Hummer H3, the PCM (or ECM) is typically located on the right-hand (passenger) side of the firewall in the engine bay.
What information do you need from me to program the module?
We only need your 17-digit Vehicle Identification Number (VIN). You can usually find this on your driver’s side dashboard (visible through the windshield), on your door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my specific check engine light codes?
This PCM is the direct solution for internal module failure codes like P0601 (Internal Control Module Memory Check Sum Error) and P0606 (ECM/PCM Processor Fault). While it can resolve other issues, it’s important to properly diagnose your vehicle, as other faulty sensors or wiring could cause different codes.
Is this compatible with vehicles other than the Canyon?
Yes. This module fits a range of 2006 GM models, including the Trailblazer, Envoy, Rainier, Isuzu Ascender, and Saab 9-7X, typically with the 4.2L engine. Please check the detailed fitment list on this page to confirm compatibility with your exact vehicle.
