Restore Full Electronic Function to Your GM Vehicle
Is your Pontiac G8, Chevy Impala, or GMC Acadia suffering from strange and unpredictable electrical problems? Flickering lights, malfunctioning power windows, a security system that acts on its own, or random warning indicators on your dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a host of frustrating issues. This replacement Body Control Module, part number 10382479, is the reliable, straightforward solution to get your car back to normal.
From the Diagnostic Bay
We once had a 2009 Pontiac G8 come into the shop with what the owner called ‘ghosts in the machine.’ The interior lights would fade in and out while driving, the horn would chirp randomly when locking the doors, and the radio would sometimes refuse to turn off after the key was removed. After checking all the usual suspects like wiring and grounds, we pinpointed the BCM. Instead of a costly and time-consuming trip to the dealer, we installed a VIN-programmed module just like this one. The ‘ghosts’ were gone, and the car’s electronics behaved perfectly. It’s a common story for this platform, and a pre-programmed module is the most efficient fix.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Vehicle security system faults or alarm sounding unexpectedly.
- ✔ The engine won’t start, or the starter doesn’t engage (security-related).
- ✔ False warning lights on the instrument cluster (e.g., ABS, Airbag, Traction Control).
- ✔ Wipers or radio behaving erratically.
- ✔ Rapid battery drain when the vehicle is off.
The Plug-and-Play Solution: A Programmed 2008-2009 G8 Body Control Module
Forget about expensive dealership programming fees and additional labor costs. We take the hassle out of the repair. When you purchase this BCM, you simply provide us with your vehicle’s 17-digit VIN. Our technicians will then program the module with the latest GM-certified software specific to your car’s exact configuration. This ensures that when the part arrives, it’s ready for installation, making the process as simple as swapping the component. This is not just a replacement; it’s a fully integrated solution for your vehicle.
Installation and Post-Install Considerations
While installation is typically a direct swap, some modern vehicles require a ‘handshake’ between new modules. After installing your new BCM, you may need to perform one of the following procedures if you notice a related warning light:
- Airbag System Sync: If the airbag light is on after installation, 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: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be necessary on certain models.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s comfort and convenience features. It controls non-engine related functions like power windows, lights, security systems, wipers, and door locks.
Do I need to get this module programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide your vehicle’s 17-digit VIN at checkout, and it will arrive ready to install.
How do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side of the dashboard, visible through the windshield.
Is this the correct part for my 2008-2009 G8 Body Control Module replacement?
Yes, this is the correct module for the 2008-2009 Pontiac G8. It also fits a wide variety of other GM vehicles listed in the description. Matching your original part number to our list ensures compatibility.
What if my airbag light comes on after installation?
This is a normal possibility. It means the new BCM needs to be electronically synced with the airbag module (SDM). This requires a ‘Setup SDM Primary Key’ procedure, which can be done by a repair shop with a professional diagnostic tool.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module.
