Is your 2008-2009 Hummer H2 experiencing a host of frustrating electrical problems? From power windows that won’t budge to interior lights that have a mind of their own, a failing Body Control Module (BCM) is often the culprit. The BCM acts as the central nervous system for your vehicle’s electronic accessories, and when it malfunctions, it can cause widespread, seemingly unrelated issues. This replacement BCM is your direct-fit, reliable solution to restore full functionality and get your vehicle back to operating as it should.
We take the guesswork out of the repair. Unlike a generic part from a salvage yard, this BCM is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This crucial step ensures that the module communicates correctly with your H2’s existing systems and options package, saving you a costly trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest, sending you a part that’s ready for installation.

Post-Installation Information
While our VIN programming makes installation much simpler, some vehicles may require additional steps. If your airbag warning light illuminates after installing the new BCM, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the airbag system (SDM) with the new BCM and can be performed by a qualified technician with a professional scan tool. Additionally, a Brake Pedal Position Relearn may be necessary on some models to ensure proper brake light and traction control operation.
Frequently Asked Questions
What does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and interior accessories.
Is this BCM ready to install when I receive it?
Yes, it is. We program the module with the latest GM software using the VIN you provide, so it’s ready to be installed without needing a trip to the dealer for initial programming. Some minor relearn procedures may be required after installation.
Where do I find my vehicle’s VIN?
Your 17-digit VIN can be found on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
What if my airbag light is on after installation?
This is a common security measure. A technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a compatible scan tool to sync the airbag module to the new BCM and turn off the light.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
