Restore Your Traverse’s Electrical System with a Hassle-Free Solution
Is your 2009-2012 Chevrolet Traverse suffering from bizarre electrical issues? Flickering dash lights, power windows with a mind of their own, or a security system that randomly acts up 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 falters, it can make your daily drive frustrating and unpredictable. Instead of facing a costly trip to the dealership for a new module and expensive programming, we offer a streamlined, reliable alternative.
This replacement Body Control Module comes with our professional Cloning Service. This isn’t just basic programming; we perform a direct data transfer from your original BCM to this replacement unit. This process ensures that all your vehicle’s specific settings, key information, and factory options are perfectly preserved. The result is a truly plug-and-play module that is ready for installation right out of the box, saving you time, money, and the headache of post-install programming appointments. Simply send us your original module, and we’ll send it back along with your ready-to-install replacement.
A Technician’s Notebook: The Phantom Drain Mystery
A customer brought in a 2011 Traverse with a classic dead-battery-every-morning complaint. They’d already replaced the battery and alternator. After hooking up my ammeter, I saw a significant parasitic draw. The culprit? The BCM wasn’t properly putting other modules to ‘sleep’ after the key was off. It was keeping the radio and instrument cluster partially active all night, slowly draining the battery. A visual inspection of the old BCM showed minor corrosion on one of the pins, likely from a past windshield leak. By cloning his original data to a new 2009-2012 Traverse BCM, we solved the drain and got him back on the road without needing to re-program keys or other systems. It’s a common failure point I’ve seen dozens of times.
Is Your Vehicle Showing These Symptoms?
A faulty BCM can cause a wide range of issues that may seem unrelated. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting (e.g., dome lights staying on, headlights not turning off).
- ✔ The security or anti-theft system preventing the car from starting.
- ✔ False warnings on the instrument cluster (e.g., ‘Service StabiliTrak’, ‘Service Airbag’).
- ✔ Communication error codes, most commonly U0140 (Lost Communication With Body Control Module).
- ✔ A parasitic battery drain that kills your battery overnight.
A Straightforward Guide to Installation
Installing your cloned 2009-2012 Traverse BCM is a manageable job for a DIY enthusiast. For the Traverse, the BCM is typically located on the left (driver’s) side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Access the Module: You will likely need to remove the lower dash panel beneath the steering column to gain access to the BCM. It’s usually held in place by a few screws or clips.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be pressed to release. 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 reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Final Steps & Relearns: Re-install the dash panel and reconnect the negative battery terminal. Follow the post-installation procedures below if necessary.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some GM vehicles may require a simple relearn procedure to ensure all systems communicate correctly.
- ✔ Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the modules and clear the light.
- ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure proper brake light operation and to keep the traction control system happy.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
What is a BCM cloning service?
What is a BCM cloning service?
Our cloning service is a process where we transfer the exact software and vehicle-specific data (like mileage and key information) from your original BCM to the replacement unit. This makes the new module a perfect electronic match for your vehicle, eliminating the need for 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. After you place your order, you will ship your BCM to us. We then clone it to the replacement unit and ship both modules back to you.
Will this fix my ‘Service StabiliTrak’ message?
It can. The BCM communicates with the traction control system. If the BCM is faulty and causing communication errors, replacing it can resolve StabiliTrak warnings. However, this message can also be caused by other issues like a bad wheel speed sensor, so proper diagnosis is key.
Is this part difficult to install myself?
For someone with basic mechanical skills, it’s a very manageable job. It typically involves removing a lower dash panel and swapping the modules. Our cloning service removes the most difficult part of the job: the computer programming.
What if my airbag light comes on after installation?
This is a known possibility on some GM vehicles. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). This is a quick procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any shop with a professional-level scan tool.
