Post-Installation Information
While this module is designed for a simple installation, some vehicles may require additional steps to ensure all systems communicate correctly. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light illuminates after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your vehicle’s airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure your brake lights and traction control system function as intended.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls many of your vehicle’s non-engine related functions. This includes power windows, locks, interior and exterior lighting, the security system, wipers, and more. It’s the brain for your vehicle’s body electronics.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as we program each module specifically for the intended vehicle.
Is this BCM difficult to install?
The BCM is typically located under the driver’s side of the dashboard. Installation involves disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors from the old module to swap in the new one. For most DIY mechanics with basic tools, it is a manageable job.
What happens if my airbag light is on after I install this?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a bi-directional scan tool to resolve this and turn off the light.
Do I need to send my old part back?
No. There is no core charge for this part. You can keep your original module.
