Restore Command Over Your Vehicle’s Electronics
Is your 2009-2012 Chevrolet Traverse experiencing a host of bizarre electrical problems? From flickering lights and malfunctioning power windows to a security system that acts on its own, the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of frustrating and unpredictable issues. This replacement Body Control Module is the definitive solution, arriving pre-programmed with the latest GM software specifically for your vehicle’s VIN. It’s designed to restore function and get you back on the road with confidence.
From the Diagnostic Bay
We recently had a 2011 Traverse come into the shop with a laundry list of complaints from the owner. The dome lights would stay on, the driver’s side power window worked intermittently, and the radio would sometimes refuse to turn off after the key was removed. The owner had already replaced the battery and checked fuses to no avail. After connecting our diagnostic tool, we saw multiple communication error codes pointing towards the BCM. Instead of a costly and time-consuming repair at the dealership, we installed a VIN-programmed Traverse Body Control Module. The installation was straightforward, and upon startup, every single one of the owner’s electrical gremlins was gone. It’s a perfect example of how one component can solve a dozen problems.
Is Your Traverse Showing Signs of a Failing BCM?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs attention:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting behavior (flickering, staying on, or not turning on).
- ✔ Malfunctioning windshield wipers or washers.
- ✔ Security system issues, including false alarms or failure to arm/disarm.
- ✔ Warning lights on the dashboard, such as the airbag or service vehicle soon light.
- ✔ Problems with the keyless entry system or remote start.
- ✔ Instrument cluster gauges behaving erratically or not working at all.
Solving Issues with Your Traverse Body Control Module
Don’t let electrical issues compromise your vehicle’s safety and convenience. This module is a direct-fit replacement, engineered to meet or exceed original equipment specifications. The most significant advantage is our programming service. When you provide your vehicle’s VIN during checkout, we flash the module with the most current GM software and vehicle-specific calibration files. This eliminates the need for expensive programming at a dealership, making the installation process as simple as possible. Simply install the module, perform any necessary relearn procedures, and enjoy restored functionality.
Installation and Post-Install Procedures
This BCM is located on the left-hand (driver’s) side of the dash in the 2009-2012 Traverse. While the physical replacement is straightforward for a skilled DIYer or technician, some post-installation steps may be required to ensure all vehicle systems communicate correctly:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible professional scan tool. 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 operation of the brake lights and stability control systems.
We always recommend consulting a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
What does a Body Control Module do on my Traverse?
The BCM acts as the brain for your vehicle’s comfort and convenience electronics. It controls functions that aren’t related to the engine, such as power windows, door locks, interior and exterior lights, the security system, and the instrument cluster.
Do I need to program this BCM?
No. We handle the programming for you before shipment. Simply provide your vehicle’s 17-digit VIN when you place your order, and the module will arrive flashed with the latest GM software and configured for your Traverse’s specific options.
What happens if I don’t provide my VIN?
Providing your VIN is essential for the programming service. Without it, we cannot program the module to match your vehicle’s configuration, and it will not function correctly. We will contact you after your purchase to obtain the VIN before we can ship the part.
Why is my airbag light on after installing the new BCM?
The BCM communicates with the airbag system’s Sensing and Diagnostic Module (SDM). After replacement, these two modules may need to be electronically ‘introduced’ to each other. This requires a ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool to turn off the light.
Is there a core charge for this part?
No, there is absolutely no core charge for this module. You can keep your original part without needing to send it back to us.
