Is Your Chevrolet Traverse Suffering from Bizarre Electrical Issues?
If you’re dealing with flickering lights, a security system that randomly engages, power windows with a mind of their own, or other strange electrical gremlins in your 2009-2012 Traverse, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s electronics, and when it starts to fail, it can cause a cascade of frustrating and unpredictable problems. Don’t let these issues compromise your vehicle’s reliability and your peace of mind. This pre-programmed BCM is the definitive, hassle-free solution to restore your vehicle’s proper function.

- Interior or exterior lights not working correctly or staying on.
- Power windows, locks, or mirrors behaving erratically.
- The security or anti-theft system preventing the car from starting.

Expert Insight: The Brain of Your Vehicle’s Body
Think of the BCM as the traffic controller for all non-engine related electronics. It manages everything from your dome light and radio to your power locks and anti-theft system. Over time, factors like voltage spikes, moisture, or simple component aging can corrupt the BCM’s internal circuits or software. When this happens, it’s not just one thing that fails; you get a host of seemingly unrelated problems. Replacing it with a correctly programmed 2009-2012 Traverse Body Control Module 20839063 is not just swapping a part—it’s restoring the central command unit for your vehicle’s comfort and security features.
Important Post-Installation Information
While this module is programmed for your vehicle, certain security and safety systems may require a final synchronization step after installation. Please be aware of the following potential procedures:
- Airbag System Sync (SDM): If your 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: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about these procedures.

Frequently Asked Questions
Why do you need my VIN number?
Your Vehicle Identification Number (VIN) allows us to program the Body Control Module with the exact software and settings that your specific vehicle requires. This ensures all features work correctly and makes the installation process as simple as possible.
Is this part difficult to install?
For someone with moderate mechanical experience, the physical installation is straightforward. The BCM is typically located under the dashboard. However, as noted above, some vehicles may require post-installation procedures with a professional scan tool to sync safety systems like the airbags.
Do I need to return my old BCM?
No. This product comes with absolutely no core charge. You can keep your original module without any extra fees or need to return it.
What happens if my airbag light comes on after installation?
This is a normal security measure in many GM vehicles. The new BCM needs to be electronically ‘introduced’ to the airbag’s Supplemental Deployment Module (SDM). A qualified technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is there a warranty on this module?
Yes. This unit is backed by our one-year replacement warranty. We stand behind the quality and programming of our modules to ensure your complete satisfaction and peace of mind.
