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 manages non-engine related functions like lights, windows, locks, wipers, security systems, and climate controls, ensuring everything works as intended.
Is this BCM ready to install when I receive it?
Yes! We program the module to your vehicle’s VIN before it ships. This makes it a true plug-and-play solution, requiring no additional dealership programming for standard operation.
My airbag light is on after installation. What should I do?
This is a common security feature. You will need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your vehicle’s airbag system (SDM) and will turn off the light.
Where is the BCM located on my 2011 Sierra Denali?
The BCM is located under the driver’s side dashboard, to the left of the steering column. It is a black box with multiple large electrical connectors.
Do I need to return my old BCM?

Will this part fix my specific problem?
This module is a direct solution for failures within the BCM itself. If your vehicle exhibits the symptoms listed, and you’ve ruled out wiring or grounding issues, this part is very likely the solution. Proper vehicle diagnosis is always recommended.
