Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, lights, wipers, the security system, and the HVAC system.
Is this BCM ready to install right out of the box?
Yes! This module is fully programmed to your vehicle’s VIN before shipping. This makes it a plug-and-play solution, requiring no additional programming from a dealership.
What if my airbag light is on after I install the new BCM?
If the airbag light is on, it means the new BCM needs to be synchronized with the airbag’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Where is the BCM located on my 2005 Silverado?
On most 2003-2007 Silverado, Sierra, and similar GM models, the BCM is located under the driver’s side of the dashboard, typically attached to a bracket near the steering column.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your old module without any hassle or extra cost.
Will this part fit vehicles other than a Silverado?
Absolutely. This BCM is compatible with a wide range of 2002-2007 GM vehicles, including the GMC Sierra, Chevrolet Tahoe, Suburban, Avalanche, Cadillac Escalade, and Hummer H2. Please verify the part number for your specific vehicle.
