An Expert’s Note on VIN Programming
“Many people think they can just grab a computer from a salvage yard and plug it in. On these GM vehicles, that simply won’t work. The PCM is the brain of the operation and is tied directly to the vehicle’s security system (Passlock/VATS). Without programming it to your specific VIN, the vehicle will not start. Our process handles all of that for you. We ensure the module is not only a physical match but a perfect digital handshake for your truck, making the installation of your 2006 GMC Envoy XL PCM replacement as simple as possible.”
Getting your trusted SUV back on the road shouldn’t be a complicated ordeal. We make it simple: provide your VIN during or after checkout, and we’ll ship a fully prepared module directly to you. This is the most reliable and straightforward 2006 GMC Envoy XL PCM replacement available.
Frequently Asked Questions
Do I need to program this module myself?
Absolutely not. This module arrives fully programmed to your vehicle’s specific VIN. It is ready for installation right out of the box. The only additional step is a simple security relearn procedure that takes about 10 minutes and requires only your key.
How do I provide my vehicle’s VIN?
You can enter your 17-digit VIN in the order notes during checkout. If you forget, don’t worry—we will contact you via email after your purchase to request the information. We cannot ship the part until we have your VIN.
Will this fix my specific problem?
This module is designed to correct all issues directly caused by a failing PCM, including common diagnostic trouble codes like P0601. However, it’s essential to ensure your vehicle has been properly diagnosed. This part will not fix problems related to other faulty components like sensors or wiring.
What is the ‘security relearn procedure’?
After installation, you will need to perform a simple key-on procedure to sync the new PCM with your vehicle’s anti-theft system. It involves turning the key to the ‘ON’ position for 10 minutes, then off, and repeating two more times. We include clear, easy-to-follow instructions with your order.
My old part has a different number on the sticker. Will this still work?
Yes. The part numbers listed (12569773, 12597776, 12606399, etc.) are often interchangeable. The critical factor is the VIN programming. As long as your vehicle is listed in the compatibility chart, our VIN-specific programming ensures this module will function correctly, regardless of the number on your original part’s sticker.
