Frequently Asked Questions
What does a Body Control Module do on a GMC Sierra?
The BCM acts as the central hub for your truck’s body electronics. It controls non-engine related functions like power windows, door locks, interior/exterior lighting, the security system, wipers, and the HVAC system.
Do I need to have this BCM programmed by a dealer?
No. This module comes pre-programmed to your vehicle’s VIN. This makes it a plug-and-play installation, saving you the time and expense of a dealership visit for programming.
My airbag light is on. Will this fix it?
A faulty BCM is a common cause of an airbag light with DTC B1001. Replacing it often resolves the issue. However, in some cases, a ‘Setup SDM Primary Key in BCM’ procedure is required using a professional scan tool to sync the new BCM with the airbag system.

The BCM is typically located under the driver’s side of the dashboard, near the steering column. Installation usually takes only a few minutes with basic hand tools.
What happens if I don’t replace a failing BCM?
Ignoring a failing BCM can lead to worsening electrical problems, potential security system issues that could leave you stranded, and the failure of critical safety features like exterior lighting.
Is this compatible with my Chevy Silverado or Tahoe?
