Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors a wide variety of electronic accessories not related to the engine. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system.
Why do I need a VIN-programmed BCM?
The BCM is specific to the features and options of your vehicle. Programming it with your Vehicle Identification Number (VIN) ensures that it communicates correctly with all other modules and that all functions work as intended. A non-programmed module will not work correctly, if at all.
Is this part difficult to install?
No, the physical installation is typically very straightforward. The BCM is usually located under the driver’s side dashboard near the steering column. It can often be replaced in under 10 minutes with basic hand tools. Since our module comes pre-programmed, the most difficult part of the job is already done for you.
My airbag light is on. Will this BCM fix it?
This module can resolve airbag lights caused by BCM communication errors, such as DTC B1001. However, after installation, some vehicles may require an ‘SDM Key Relearn’ procedure using a professional scan tool to sync the new BCM with the airbag system and clear the light.
What if this doesn’t fix my problem?
While this 2007-2011 Tahoe Body Control Module is the solution for the vast majority of the symptoms listed, complex electrical issues can sometimes have other causes, like a bad ground or wiring problem. We recommend confirming your diagnosis before ordering. This part is backed by a one-year warranty for any issues with the module itself.
