Frequently Asked Questions
What does a Body Control Module do on a Suburban?
The BCM acts as the central computer for your vehicle’s body electronics. It manages non-engine related functions like power windows, door locks, the security system, interior and exterior lights, wipers, and the HVAC system, ensuring they all work together correctly.
Is this BCM difficult to install?
No, installation is typically very straightforward. The BCM is usually located under the driver’s side dashboard, near the steering column. It’s a plug-and-play process that often takes less than 15 minutes with basic tools. Because it comes pre-programmed, no special computer tools are needed for the initial setup.
Will I need to get this programmed by a dealer?
Absolutely not. We program the module to your vehicle’s specific VIN before it ships. This means it’s ready to install right out of the box, saving you the time, hassle, and high cost of dealership programming.
What if my airbag light stays on after installation?
In some cases, particularly if you had an airbag code like B1001, the new BCM may need to be synced with the airbag system’s SDM (Sensing and Diagnostic Module). This is a simple “Setup SDM Primary Key in BCM” procedure that can be done with a professional-grade scan tool.
Does this part fit other GM trucks besides the Suburban?
Yes, this BCM is compatible with a wide range of 2007-2013 GM trucks and SUVs, including the Chevrolet Silverado, Tahoe, and Avalanche; the GMC Sierra and Yukon; and the Cadillac Escalade. We recommend verifying the part number 2007-2011 Suburban 1500 BCM 25835966 or one of its interchanges to ensure a perfect fit.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module without the hassle of needing to return it.
