Restore Full Electrical Function to Your Chevrolet Traverse
Are you battling bizarre electrical problems in your 2009-2012 Chevrolet Traverse? Intermittent wipers, flickering interior lights, power windows with a mind of their own, or a security system that won’t cooperate are classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features. When it fails, it can cause a cascade of frustrating, hard-to-diagnose issues. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
We offer a straightforward, reliable solution. This is a replacement BCM that comes with our expert Cloning Service. This means we transfer the essential data from your original, failing module directly onto this replacement unit. The result? A true plug-and-play component that restores function without the exorbitant costs and scheduling headaches of a dealership visit. Simply send us your original BCM, and we’ll handle the rest, returning both your original and the ready-to-install replacement to you.
A Technician’s Notebook: The Case of the Haunted Acadia
A customer brought in a 2011 GMC Acadia—a vehicle that shares its core platform with the Traverse—with a list of symptoms that sounded like a poltergeist was at work. The radio would turn on by itself, the liftgate would open randomly, and the dash lights would flicker at highway speeds. They’d already replaced the battery and checked the main grounds. After connecting my scan tool, I saw a slew of U-codes (communication errors) pointing to the BCM. These modules often fail from internal corrosion on the circuit board or failing solder joints after years of thermal cycles. By installing a BCM with cloned data, we had the vehicle’s full functionality restored in under an hour, bypassing a multi-day wait and programming fee at the dealer.
Common Signs of a Failing BCM
If you’re experiencing these issues, a faulty BCM is the likely culprit. A replacement 2009-2012 Traverse Body Control Module is the definitive fix for:
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system or keyless entry acting up or failing completely.
- ✔ Wipers operating intermittently or not parking in the correct position.
- ✔ Instrument cluster warnings like “Service Theft Deterrent System.”
- ✔ Communication error codes, such as U0140, U0155, or other U-series codes.
A Straightforward Guide to Installation
Installing your new BCM is a manageable task for a DIYer with basic tools. The BCM in the 2009-2012 Traverse is typically located on the driver’s side, to the left of the steering column behind the lower dash panel.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Access the Module: Remove the lower dash panel beneath the steering wheel. This may require removing a few screws or clips.
- Locate the BCM: Identify the BCM. It’s a plastic box with several large multi-pin electrical connectors plugged into it.
- Disconnect and Remove: Carefully release the locking tabs on each electrical connector and unplug them. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount the replacement BCM in the same location, reconnect all electrical connectors securely, and reinstall the lower dash panel.
- Final Steps: Reconnect the negative battery terminal. Start the vehicle and test all functions (lights, windows, locks, etc.). Note the post-installation procedures below.
Important Post-Installation Information
Thanks to our cloning service, most vehicle-specific programming is already handled. However, some security and safety systems may require a relearn procedure after the BCM is swapped.
- Airbag System Sync: If the 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 BCM with the airbag module.
- Brake Pedal Position Relearn: On some models, the brake pedal position sensor may need to be recalibrated to ensure brake lights and stability control systems function correctly.
Disclaimer: Vehicle systems vary. Always have a factory service manual available for your specific VIN for detailed instructions and torque specs.

Frequently Asked Questions
What is the ‘Cloning Service’?
Our cloning service is a process where we transfer the specific configuration, security data, and operational parameters from your original BCM to the replacement unit. This makes the new module a perfect electronic match for your vehicle, eliminating the need for expensive and time-consuming dealership programming.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, we need your original module to extract the data. We will return your original module along with the newly prepared replacement unit. We do not keep your original part.
Is this a plug-and-play solution?
Yes, for the most part. Because we clone your vehicle’s data, the BCM will be ready to install and function immediately. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which may require a professional scan tool.
What happens if the airbag light comes on after installation?
This is a known possibility and is due to the BCM needing to re-establish a secure handshake with the airbag system’s Sensing and Diagnostic Module (SDM). A repair shop with a capable bidirectional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Will this fix my specific electrical problem?
This BCM is the solution for a wide range of common electrical failures. Please review the ‘Common Signs of a Failing BCM’ list above. If your symptoms match, this part is very likely the solution you need. Proper diagnosis is always recommended.
