Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system. When it fails, these systems can become erratic.
Is this part truly ‘plug and play’?
Yes. We program the module to the VIN you provide during checkout. This ensures it communicates correctly with your vehicle’s other systems right out of the box, eliminating the need for expensive dealership tools. In some cases, if the airbag light persists, a simple ‘SDM key update’ may be needed with a professional scan tool, but the core programming is done.
Where is the BCM located on my truck?
On most compatible GM trucks and SUVs, including the GMC Sierra and Chevy Silverado, the BCM is located under the driver’s side dashboard, near the steering column. Installation typically takes only a few minutes with basic hand tools.
Will this fix my airbag light with code B1001?
A faulty BCM is a very common cause of DTC B1001. Replacing the module often resolves this code. However, after installation, you may need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to fully sync the new BCM with the airbag system and turn off the light.
How do I know if this is the right part for my vehicle?
