Frequently Asked Questions
What does the Body Control Module do on my Sierra?
The BCM acts as the central computer for your truck’s body electronics. It manages non-engine related functions like your interior and exterior lights, power windows and locks, wipers, security system, and HVAC climate controls.
Is this BCM truly plug-and-play?
Yes. Because we program it to your vehicle’s VIN before it ships, it is ready for immediate installation and operation. This process syncs the module with your truck’s specific features and security system, eliminating the need for further dealership programming.
My airbag light is on. Will this fix it?
This module often resolves issues causing the airbag light, particularly DTC B1001. However, in some cases after installation, a procedure called ‘Setup SDM Primary Key in BCM’ may be needed using a professional scan tool to sync the new BCM with the airbag system and turn off the light.
Where is the BCM located on my truck?
The BCM is typically located under the driver’s side of the dashboard, near the steering column. It is an accessible location that makes for a quick and straightforward replacement.
Do I need to return my old BCM?
No. We do not require a core return for this part. You can keep or dispose of your old module at your convenience, saving you time and shipping costs.
