From the Technician’s Bench: The Importance of the Security Relearn
As a veteran tech, I’ve seen countless DIY jobs go sideways because of one missed step. On these GM SUVs (Envoy, Trailblazer, etc.), the vehicle’s anti-theft system (Passlock/Passkey) is tied to the PCM. After installing your new 2004 2005 GMC Envoy XUV PCM, the vehicle won’t start until you perform a simple ‘Security Relearn’ procedure. It doesn’t require any special tools—just your ignition key and about 30 minutes of patience. This procedure syncs the new module with your vehicle’s security system. We include clear instructions to make this final step straightforward, ensuring your repair is a complete success.
Stop guessing and start driving. By providing us with your VIN upon purchase, you are ensuring that the heart of your vehicle’s electronics is perfectly matched and ready to restore the performance you’ve been missing. This is the most reliable way to fix your faulty 2004 2005 GMC Envoy XUV PCM and regain peace of mind on the road.
Frequently Asked Questions
Do I need to get this PCM programmed?
No. The main benefit of our service is that we program the module for you before it ships. Simply provide your vehicle’s 17-digit VIN during or after checkout, and it will arrive ready to be installed.
Is a security or anti-theft relearn procedure required?
Yes, in nearly all cases. After installation, you will need to perform a simple security relearn procedure which pairs the new computer to your vehicle’s anti-theft system. This process typically takes about 30 minutes and does not require any special tools. We provide easy-to-follow instructions.
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 failing PCM itself. However, it is essential to ensure your vehicle’s issues have been properly diagnosed, as this part will not fix problems caused by other faulty sensors or mechanical components.
Where do I find my VIN?
Your Vehicle Identification Number (VIN) can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
