Installation & Post-Install Procedures
Installation is straightforward for the average DIYer. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the negative battery terminal, unplug the electrical connectors from the old module, remove it, and install the new one in its place. While programming is done for you, some vehicles may require a simple relearn procedure.
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure proper brake light and traction control operation.
- No Core Charge: You are not required to return your old, faulty module. There is no core charge, saving you time and hassle.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the main computer for your vehicle’s non-engine related electronics. It controls functions like power windows, door locks, interior and exterior lighting, wipers, the security system, and the HVAC system.
Do I need to take my vehicle to a dealer after installing this part?
No. This BCM comes pre-programmed to your vehicle’s VIN. This means you can install it yourself and it will work immediately, saving you a trip to the dealership for programming.
Is this part difficult to install?
Installation is generally simple and can be done in under 15 minutes with basic tools. The BCM is located under the driver’s side dash. You simply disconnect the battery, unplug the old module, and plug in the new one.
What if my airbag light is on after installation?
If the airbag light appears, it means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key’ procedure, which can be done with a professional scan tool.
Will this fix my specific electrical problem?
This module is the solution for a vast majority of the symptoms listed, such as failing lights, locks, and HVAC controls. If you’ve ruled out fuses and wiring, a faulty BCM is the most likely cause.
