Flickering lights, malfunctioning power windows, or a car that refuses to start can often be traced back to a single component: the Body Control Module (BCM).

This replacement Body Control Module is the definitive solution, arriving pre-programmed to your car’s specific VIN for a straightforward installation.
Common Symptoms of a Failing Pontiac G8 BCM

Installation and Post-Install Considerations
Installation is typically straightforward, as the BCM is located in the center dash area on the Pontiac G8. However, after installation, some vehicles may require additional steps to ensure all systems are synchronized:
- Airbag System Sync: If the airbag warning light is on after you install the new BCM, 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: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and to satisfy the traction control system.
Frequently Asked Questions
What does the Body Control Module do on my G8?
The BCM is a computer that manages and controls many of the non-engine related electronic functions in your car. This includes power windows, locks, lights, security system, wipers, and various other comfort and convenience features.
Is this part difficult to install?
For someone with moderate mechanical skill, the physical replacement is not overly complex as it’s located in the center dash. The main benefit of our module is that it comes pre-programmed, which saves you the most difficult step of using specialized dealer tools.
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 the module until we receive your VIN, as the programming is essential for it to work in your car.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light is on after installation?
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 professional-grade diagnostic tool to resolve this.
