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 controls non-engine related functions like power windows, door locks, interior and exterior lighting, the security system, climate controls, and windshield wipers.
Is this part truly plug-and-play?
Yes. We program the module to your vehicle’s VIN before shipping. This ensures it communicates correctly with your truck’s other computers right out of the box, eliminating the need for any additional programming from a dealer or mechanic.
Where is the BCM located on my 2004 GMC Yukon?
On most 2003-2006 GMC Yukons, Tahoes, and similar models, the BCM is located under the driver’s side of the dashboard, near the steering column. It is a black box with several large electrical connectors.
My airbag light is on. Will this fix it?
A failing BCM can cause a false airbag light. While this module will fix the underlying BCM issue, you may need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure after installation to sync the systems and turn off the light.
Do I need any special tools for installation?
Basic hand tools are typically all that’s needed to access and replace the module. The most important step is to disconnect the vehicle’s battery before you begin to prevent any electrical shorts and to help reset the system.
