Post-Installation Procedures
In most cases, this module is a plug-and-play solution. However, depending on your vehicle’s specific configuration, a couple of simple relearn procedures may be necessary:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be required.

Frequently Asked Questions
What does the Body Control Module do on my Pontiac G8?
The BCM is a computer that manages and controls many of your car’s non-engine-related functions, such as power windows, locks, lights, security system, wipers, and the radio. It’s the command center for passenger comfort and convenience electronics.
Do I need to get this BCM programmed by a dealer?
No. We program the module to your car’s specific VIN before we ship it to you. This makes the unit ready for installation right out of the box, saving you a trip to the dealership and additional programming fees.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your order until we receive this information to ensure correct programming.
What if the airbag light comes on after I install it?
This can happen occasionally. 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 professional-grade diagnostic tool to resolve this.
Is there a core charge for my old BCM?
No, there is no core charge. You are not required to send your original BCM back to us, which saves you time and return shipping costs.
