Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls many of the non-engine related electronic functions, such as power windows, locks, lights, wipers, security system, and more.
How do I provide my VIN for programming?
After you complete your purchase, we will contact you to request your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is essential for the part to work correctly.
Is this part difficult to install?
For most models, the BCM is located under the steering column or in the center dash area. The physical replacement is typically straightforward, involving disconnecting the battery and swapping the module. However, some vehicles may require post-installation procedures as noted in our documentation.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light is on after installation?
If the airbag light illuminates, it means the new BCM needs to be synced with the vehicle’s airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a professional technician with a compatible diagnostic tool.
