An Expert’s Note on GM Electronics
As a technician, I’ve seen countless GMT360 platform vehicles like the Envoy and Trailblazer come in with bizarre electrical gremlins. Often, the root cause is a failing PCM. Many people try to save a few dollars with a junkyard unit, only to find it won’t communicate with the Body Control Module (BCM) or anti-theft system because it’s not programmed correctly. This creates a bigger headache than they started with. A pre-programmed 2006 GMC Envoy PCM that’s matched to your VIN is the only way to guarantee a successful, hassle-free repair and avoid these frustrating compatibility roadblocks.
Frequently Asked Questions
Do I need to do any programming myself?
No. This module arrives fully programmed to the VIN you provide. The only thing you will need to do is a simple security relearn procedure, which involves turning the key in the ignition. We include easy-to-follow instructions for this process.
How 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.
Will this fix my check engine light?
This module will correct any check engine light and diagnostic trouble codes (DTCs) that are caused by a faulty PCM itself (like code P0601). It is important to ensure your vehicle has been properly diagnosed, as the check engine light can be triggered by other failing sensors or components.
What is the security relearn procedure?
It’s a simple process that syncs the new PCM with your vehicle’s anti-theft system (GM Passlock/VATS). It typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating this two more times. This allows the systems to recognize each other. Detailed instructions are included with your order.
Is this compatible with other part numbers?
Yes, this 2006 GMC Envoy PCM is a direct replacement for a wide range of part numbers, including 12569773, 12588650, 12593531, 12600818, and many others listed in the full description. It is designed to be a comprehensive solution for the specified vehicles.
