Is Your Chevrolet Traverse Experiencing Strange Electrical Problems?
If your 2009-2012 Chevrolet Traverse is suffering from baffling electrical issues, a failing Body Control Module (BCM) is often the culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, controlling everything from your power windows and locks to the interior lights and security system. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems, making your vehicle unreliable and difficult to use.
From the Diagnostic Bay
We had a 2011 Traverse come into the shop with a complaint that was driving the owner crazy. The interior dome lights would randomly turn on while driving, the key fob worked intermittently, and sometimes the radio would just shut off. They had already replaced the battery, thinking it was a power supply issue. After running diagnostics, we traced the communication errors back to a faulty BCM. Replacing the original module with a correctly programmed unit solved every single one of the ghost-like electrical problems. This is a classic failure scenario for this platform.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The anti-theft or security system acting up, preventing the car from starting.
- ✔ Keyless entry remote failing to work consistently.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ False warning lights or messages appearing on the instrument cluster.

Post-Installation Information
While our VIN programming makes installation straightforward, some vehicles may require additional steps to sync all systems perfectly. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated 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: On some models, a brake pedal position sensor relearn may be necessary to ensure correct operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
