Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, HVAC system, and the security system. It’s the command center for passenger comfort and convenience features.
Is this module ready to install right out of the box?
Yes! This BCM is pre-programmed to your vehicle’s specific VIN before shipping. This ensures it communicates correctly with your vehicle’s other systems for a true plug-and-play installation, with no need for additional dealer programming.
Where is the BCM located on my 2008 Sierra 2500?
On most compatible GM trucks and SUVs, including the 2007-2011 Sierra 2500, the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column. Installation usually takes only a few minutes.
What if my airbag light is still on after installing the new BCM?
If the airbag light remains on, it’s typically due to a loss of communication between the new BCM and the airbag’s SDM. A professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ relearn procedure to sync the modules and clear the light.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep or dispose of your old module without any hassle.
Will this 2007-2011 Sierra 2500 BCM fit other vehicles?
Absolutely. While it’s a perfect fit for the Sierra, it’s also compatible with a wide range of 2007-2013 GM models, including the Chevrolet Silverado, Suburban, Tahoe, Avalanche, and the Cadillac Escalade. Please verify the part number for your specific vehicle.
