Is your 2009-2012 Chevrolet Traverse suffering from bizarre electrical issues? The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating problems. This replacement Body Control Module, part number 25826125, is the definitive solution to restore your vehicle’s functionality and peace of mind. We take the guesswork out of the repair by pre-programming the module to your vehicle’s specific VIN, ensuring it arrives ready for installation with the latest software updates from GM.
From the Diagnostic Bay
We had a 2011 Traverse in the shop that was driving the owner crazy. The dome lights would stay on, the driver’s side power window worked intermittently, and the remote key fob would only lock the doors, not unlock them. The customer had already replaced the window switch and a dozen fuses. After hooking up our scanner, we saw multiple communication loss codes pointing to the BCM. Instead of a complex wiring chase, a new VIN-programmed BCM was the answer. After a straightforward installation, all the strange electrical gremlins vanished. It’s a perfect example of how one failing module can create multiple, seemingly unrelated symptoms.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating incorrectly.
- ✔ The security system or keyless entry failing to work as expected.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Intermittent starting problems or a ‘Service Theft System’ message.
- ✔ Communication failures with other vehicle modules.
Why Choose Our Pre-Programmed 2009-2012 Traverse BCM?
Replacing a BCM isn’t just a simple swap. A new module from a dealership requires expensive programming and calibration tools. We eliminate that hassle. By providing your VIN during checkout, you receive a module that is loaded with your vehicle’s specific configuration and the most current GM software. This ensures a smoother installation process and optimal performance. This module is a direct replacement for a wide range of original part numbers, including 15826125, 22860591, 20935349, and many more listed in our fitment guide.
Installation and Post-Install Steps
Physically replacing the BCM is typically straightforward, often located under the driver’s side dashboard. Once installed, most functions should be immediately restored. However, in some cases, additional steps may be needed:
- 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: 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 for vehicle-specific instructions.
