Post-Installation Procedures
While this GM BCM Body Control Module is programmed for your VIN, some vehicles may require a simple relearn procedure after installation to ensure all systems communicate correctly.
- Airbag System Sync: If the airbag warning light is on after you install the BCM, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system and requires a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors body electronics. This includes power windows, locks, lights, wipers, security systems, and more. It acts as a hub, ensuring all these features work together correctly.
Is this BCM truly plug-and-play?
Yes, for the most part. We program it to your vehicle’s VIN before shipping, which handles the most critical step. This allows the vehicle to start and run. However, as noted, some vehicles may require additional minor relearn procedures for systems like the airbags or brake sensor, which can be done with a suitable scan tool.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the part to function in your vehicle.
What happens if my airbag light is on after installation?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system (SDM). A mechanic with a bi-directional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my original BCM back?
No. There is no core charge for this part. You can keep your original module.
