Is your 2009-2012 Chevrolet Traverse suffering from bizarre electrical issues? Flickering lights, malfunctioning power windows, or a security system that has a mind of its own are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement BCM, part number 15921352, is the definitive solution to restore your vehicle’s functionality and peace of mind.
From the Diagnostic Bay
We had a 2011 Traverse come into the shop with the strangest set of symptoms. The owner said the radio would randomly turn off, the driver’s side power window wouldn’t work, and the anti-theft light was always flashing. He’d already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication loss codes with various systems. This pointed us directly to the central hub: the BCM. A faulty BCM was scrambling signals across the vehicle’s network. Installing a VIN-programmed replacement like this one cleared all the codes and fixed every single issue in one go. It’s a perfect example of how one module can cause widespread electronic chaos.
Common Symptoms of a Failing Traverse BCM
- ✔ Intermittent or non-working power windows, door locks, and mirrors.
- ✔ Erratic behavior from dashboard gauges or warning lights (like the airbag or security light).
- ✔ The security system preventing the vehicle from starting (Service Theft System message).
- ✔ Interior dome lights or exterior lights staying on or not turning on at all.
- ✔ HVAC and climate control systems not functioning correctly.
- ✔ Key fob not working to lock or unlock the doors.
- ✔ Communication error codes (U-codes) stored in the vehicle’s computer system.
Diagnosing and Replacing Your 2009-2012 Traverse Body Control Module
This isn’t just a part; it’s a complete, ready-to-install solution. We take the hassle and expense out of the repair process. When you order, simply provide us with your vehicle’s VIN. Our technicians will then program the module with the latest GM software specific to your Traverse’s configuration. This means no expensive trip to the dealership for programming is required. The module arrives at your door ready for a straightforward installation.
While the physical replacement is often simple, some vehicles may require a couple of quick post-installation procedures. For instance, if the airbag light appears, a ‘Setup SDM Primary Key in BCM’ procedure may be needed to sync the systems. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary. These can typically be performed with a high-level diagnostic scan tool. Our goal is to make the process as seamless as possible, getting you back on the road quickly and safely with a fully functional vehicle.

Frequently Asked Questions
What does the Body Control Module (BCM) do on my Traverse?
The BCM is a computer that controls and monitors most of your vehicle’s non-engine related electronic functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and aspects of the climate control system.
Is this BCM truly plug-and-play?
Yes, it comes pre-programmed to your vehicle’s VIN, making it a plug-and-play installation. In some cases, simple relearn procedures like for the brake pedal position sensor or airbag system sync may be required, which can be done with a capable scan tool.
Where is the BCM located on a 2009-2012 Chevy Traverse?
On the 2009-2012 Traverse, the Body Control Module is typically located on the left-hand (driver’s side) of the dashboard, often up under the dash near the steering column.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive your VIN, as the programming is specific to your vehicle.
Will this part fit other vehicles besides the Traverse?
Yes, this BCM is compatible with a wide range of GM vehicles from roughly 2006 to 2013, including the Acadia, Enclave, Impala, various Express/Savana vans, and more. Please check the detailed fitment list to confirm for your specific model.
