Is Your Traverse Experiencing Strange Electrical Issues?
If your 2009-2012 Chevrolet Traverse is suddenly acting possessedโwith flickering dashboard lights, power windows and locks that have a mind of their own, a security system that won’t cooperate, or even a frustrating no-start conditionโa failing Body Control Module (BCM) is the most likely culprit.

Expert Insight: The BCM’s Domino Effect
As a veteran technician, I’ve seen firsthand how a failing BCM can baffle vehicle owners. A customer once brought in a GMC Acadia where the radio would turn on by itself and the power liftgate would open randomly. They had already replaced the battery and checked fuses, but the gremlins persisted. The issue was a failing BCM sending erratic signals across the vehicle’s network. Once we installed a VIN-programmed module like this one, all the strange issues vanished instantly. It’s a powerful reminder that this single component is crucial for the proper operation of dozens of systems you rely on every day.
Installation & Post-Install Notes
While installation is straightforward, please be aware of a few potential post-installation procedures that may be required for your specific vehicle:
- 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: In some cases, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control function.
We always recommend consulting a factory service manual or a qualified technician for specific guidance related to your vehicle.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide variety of non-engine-related functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and more.
How do I know if my BCM is failing?
Common signs include erratic behavior of electronic components, such as lights flickering, horn honking randomly, key fob not working, security light staying on, or the vehicle not starting. A professional diagnosis is the best way to be certain.
What happens after I place my order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. We use this to program the BCM with the correct, most up-to-date software from GM before we ship it to you.
Is this part difficult to install?
The physical replacement of the BCM is typically straightforward for someone with moderate mechanical skill. On a 2009-2012 Traverse, it is located on the left-hand (driver’s) side of the dash. The main benefit of our service is that the complex programming is already done for you.
Will I need to do any additional programming after installation?
The main vehicle programming is complete. However, as noted above, some vehicles may require a simple relearn procedure for the airbag system or brake pedal position sensor, which requires a professional scan tool.
My original part has a different number. Will this still work?
Yes. This BCM is a direct replacement for all the part numbers listed in the description. GM often consolidates multiple part numbers into a single, updated replacement part over time.
