Restore Full Functionality to Your Chevrolet Traverse
Are you dealing with bizarre electrical issues in your 2009-2012 Chevrolet Traverse? Intermittent power windows, flickering dash lights, a security system that acts up, or even a no-start condition can all point to a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can turn your reliable SUV into a source of constant frustration. This isn’t just an inconvenience; it can be a serious safety concern when lights or security systems fail unexpectedly.
This is a direct-fit replacement Body Control Module for your vehicle, but with a critical service that saves you hundreds of dollars and a trip to the dealership. We offer a professional cloning service. Simply send us your original BCM, and we will transfer all the vital, vehicle-specific data—including key programming and security information—to this replacement unit. The result is a truly plug-and-play module. No expensive dealer programming, no special scan tools required. Just install it, and you’re back on the road.
A Technician’s Notebook
I remember a 2011 Traverse that came into my bay with a laundry list of complaints from the owner. The radio would turn on and off by itself, the driver’s side power window worked only when it wanted to, and the anti-theft light would flash randomly, sometimes preventing the car from starting. The owner had already replaced the battery and checked fuses. After connecting my scan tool, I found multiple ‘U’ codes, indicating a loss of communication between various modules. This is a classic sign. The issue wasn’t the individual components; it was the central BCM failing to manage them. We swapped in a cloned 2009-2012 Traverse BCM, and every single electrical gremlin vanished instantly. It’s a repair that brings immense relief to the vehicle owner.
Is Your Traverse Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely culprit:
- ✔ Erratic or non-functional power windows, locks, and mirrors.
- ✔ Interior dome lights or dashboard lights flickering or staying on.
- ✔ The security or anti-theft system engaging incorrectly, causing no-start situations.
- ✔ Horn honking randomly or not working at all.
- ✔ Inconsistent operation of windshield wipers.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or other U-codes.
A Straightforward Guide to Installation
Installing your cloned 2009-2012 Traverse BCM is a manageable job for a confident DIYer. The BCM is typically located on the driver’s side, under the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On the Traverse, you’ll find the BCM mounted to the left of the steering column, often behind a lower dash panel. You may need to remove this trim panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, cloned BCM in the same location and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair was successful.
Important Post-Installation Information
While our cloning service makes this a near plug-and-play process, some GM vehicles may require simple relearn procedures:
- ✔ Airbag System Sync: If the airbag light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the airbag system with the new BCM and requires a professional-grade scan tool. This is only necessary if the light appears.
- ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
- ✔ Disclaimer: Always refer to a factory service manual for procedures specific to your vehicle’s year and model.

Frequently Asked Questions
Q: What exactly is a ‘Cloning Service’?
A: Cloning is the process of transferring the exact software, VIN, key codes, and security settings from your original BCM to this replacement unit. This makes the new module a perfect electronic match for your vehicle, eliminating the need for expensive and time-consuming dealership programming.
Q: Do I need to send my original BCM to you?
A: Yes. For the cloning service to work, we need your original module to extract the data. Once the service is complete, we ship both your original module and the newly programmed replacement unit back to you.
Q: Is this a difficult part to install myself?
A: For someone with basic mechanical skills, it’s very manageable. The BCM is usually located under the driver’s side dashboard and held in by a few bolts or clips. The main challenge is accessing it. Once installed, our cloning service ensures it’s ready to go without further programming.
Q: What happens if my airbag light comes on after installation?
A: This is uncommon, but if it happens, it means the BCM needs to be electronically synced with the airbag’s Supplemental Deployment Module (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any professional mechanic with a compatible scan tool.
Q: Do you keep my old BCM?
A: No, we do not require your old module as a core. Your original BCM is always returned to you along with the programmed replacement unit for your records or as a backup.
