Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer in your vehicle that manages and controls electronic accessories related to the vehicle’s body. This includes power windows, locks, interior/exterior lighting, wipers, the security system, and the HVAC climate control system. When it fails, any of these systems can malfunction.
Is this module truly ‘plug-and-play’?
Yes. We pre-program the module to your vehicle’s unique VIN before shipping. This ensures it communicates correctly with your truck’s other electronic systems right out of the box, eliminating the need for additional programming at a dealership.
What if my airbag light is on after installation?
In some cases, a persistent airbag light after installation requires a simple sync procedure. A professional scan tool must be used to perform the ‘Setup SDM Primary Key in BCM’ function. This re-establishes communication between the new BCM and the airbag system, turning off the light.
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 old module without any core charge or hassle.
How can I be sure the BCM is my problem?
While professional diagnosis is always best, a failing BCM is a very common cause for multiple, seemingly unrelated electrical issues like the ones listed above (e.g., windows and radio not working simultaneously). If you’re experiencing several of these symptoms, the BCM is the most likely culprit.
