Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle responsible for managing and controlling various electronic accessories, such as power windows, lights, security systems, wipers, and door locks. It ensures all these comfort and convenience features operate correctly.
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your vehicle’s specific options and features. This ensures the module works perfectly right out of the box and communicates correctly with your other vehicle systems.
Is this part difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. It’s often located under the dash. Since we pre-program it, you skip the most complex step. However, some vehicles may require post-installation procedures like an airbag or brake sensor relearn, which may require a professional scan tool.
What happens if my airbag light is on after installation?
If the airbag light illuminates, it means the new BCM needs to be synced with the airbag’s computer (SDM). A technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional diagnostic tool to complete the handshake between the two modules.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
