Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central computer for your vehicle’s body-related electronics. It manages functions that aren’t related to the engine, such as power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC climate control system.
Is this module truly ‘plug-and-play’?
Yes. Because we pre-program the module to your vehicle’s VIN, it is ready for installation right out of the box. In most cases, you simply disconnect the old module and connect the new one. However, please see our installation tips regarding a potential airbag system sync if the warning light remains on.
What if my airbag light is on after installation?
If the airbag warning light is illuminated (often with code B1001), it means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). This requires a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync, not a full reprogramming, and can be done by most competent repair shops.
Where is the BCM located on my truck?
On most compatible GM trucks and SUVs, including the Sierra and Silverado, the BCM is located under the driver’s side of the dashboard, near the steering column. Installation typically takes only a few minutes with basic tools.
How do I know if this is the right part for my vehicle?
This 2007-2011 Sierra 1500 Body Control Module fits a wide range of GM models. The best way to confirm is to match your original part number to one of the many interchangeable numbers listed, such as 15878753 or 25844480. You can also use the vehicle fitment guide on this page to ensure compatibility.
