Frequently Asked Questions
What does a BCM do on a 2011 GMC Sierra?
The Body Control Module, or BCM, acts as the central computer for your truck’s body electronics. It manages non-engine-related functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC climate control system.
Is this BCM truly plug-and-play?
Yes. We program the module to your vehicle’s VIN before shipping. This ensures it has the correct software and configuration for your specific truck, allowing for a direct installation without requiring a trip to the dealership for additional programming.
Do I need to send my old BCM back?
No. We do not require a core return for this part. You can keep or dispose of your original module, making the process simpler and more convenient for you.
What if my airbag light stays on after installation?
In some cases, particularly if you have an active DTC B1001, the new BCM may need to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed with a professional-grade scan tool.
