Frequently Asked Questions
Do I need to do any programming or flashing myself?
No. This module is completely plug-and-play. We handle all the programming before it ships. Simply provide your vehicle’s VIN during or after checkout, and it will arrive ready for installation.
Will I need to perform a security relearn procedure?
Yes, on most GM vehicles of this era, a simple security relearn (often called a key-cycle procedure) is required after installation. This process syncs the new PCM with your vehicle’s anti-theft system and typically takes 10-30 minutes to complete with just your ignition key. Instructions are readily available online and are easy to follow.
Is this compatible with other GM trucks and SUVs?
Absolutely. While this listing focuses on the programmed 2006 Hummer H3 PCM, this module also fits a wide range of other GM models like the Chevy Colorado, GMC Canyon, Trailblazer, and Envoy from 2004-2006. Please check the detailed fitment list to confirm compatibility with your specific vehicle.
How do I provide my VIN?
You can add your 17-digit Vehicle Identification Number (VIN) in the notes section during checkout or send it to us in a message after you place your order. We cannot ship the module until we receive your VIN, as the programming is specific to your vehicle.
Will this fix my specific check engine light codes?
If your diagnostic trouble codes (DTCs) point to an internal module failure (like P0601) or a communication error, this part is the correct solution. It’s the central command unit, and its proper function is essential for clearing a wide variety of engine and transmission codes.
