Frequently Asked Questions
What does a Body Control Module (BCM) actually do?
The BCM is a computer in your vehicle that controls and monitors most of the non-engine-related electronic functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system. When it fails, you experience the strange electrical issues this part is designed to fix.
Is this module truly plug-and-play?
Yes. Because we pre-program the module to your vehicle’s VIN, it is ready for installation upon arrival. In most cases, you simply disconnect the battery, swap the old module with the new one, and reconnect the battery. No dealership visit for programming is required.
What if my airbag light is on after installation?
In some vehicles, the new BCM needs to be synced with the airbag system’s computer (SDM). If the airbag light stays on after installation, a procedure called “Setup SDM Primary Key in BCM” will need to be performed using a professional-grade scan tool. This is a quick procedure for any qualified repair shop.
Do I need to send my old BCM back?
No. There is no core charge or requirement to return your original module. This simplifies the process for you and saves you money on shipping.
