Restore Your Traverse’s Electrical System with a Hassle-Free Solution
Is your 2009-2012 Chevrolet Traverse suffering from bizarre electrical problems? Flickering lights, malfunctioning power windows or locks, a security system that acts up, or even a frustrating no-start condition can often be traced back to a single culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s comfort and convenience features, a faulty BCM can turn your reliable SUV into a source of daily frustration. In my 20 years of experience, I’ve seen how a failing BCM can mimic a dozen other problems, leading to expensive and incorrect diagnoses.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We offer a professional Cloning Service for this BCM, part number 15828601. This means we transfer the exact data from your original module to this replacement unit. The result? A true plug-and-play component that requires no expensive trip to the dealership for programming. You get your vehicle’s functions back to normal without the typical hassle and high cost.
A Technician’s Notebook: The Case of the Haunted Acadia
A customer brought in a 2011 GMC Acadia (which shares the same platform and BCM as the Traverse) with a list of strange symptoms. The dome lights would stay on, the radio would shut off randomly, and the liftgate wouldn’t open. They had already replaced the battery and checked fuses with no luck. After connecting my scan tool, I found multiple ‘loss of communication’ codes (U-codes) pointing to the BCM. A visual inspection revealed the problem: water intrusion from a leaky windshield cowl seal had dripped directly onto the BCM, causing corrosion on the connectors. By replacing the BCM with a cloned unit and fixing the leak, we restored all functions perfectly, saving the customer from a costly and confusing diagnostic journey at the dealer.
Common Signs of BCM Failure
If you’re experiencing any of the following, a failing BCM is a likely cause. A professional diagnosis is always recommended, but these are classic symptoms I see in the shop:
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft system light is on, preventing the engine from starting.
- ✔ The horn sounds randomly or doesn’t work at all.
- ✔ Warning lights on the dashboard appear without a clear cause.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0140, U0155, or other U-codes.
- ✔ Wipers or climate control fans behaving unpredictably.
A Straightforward Guide to Your BCM Installation
Installing your cloned 2009-2012 Traverse BCM is a manageable job for a confident DIYer. The key is our cloning service, which eliminates the need for advanced programming tools.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electrical components.
- Locate the BCM: On the 2009-2012 Traverse, the BCM is typically located on the left-hand (driver’s) side of the dashboard, often behind the lower dash panel near the steering column.
- Remove Trim Panels: You may need to carefully remove the lower dash panel or knee bolster to gain access. These are usually held by clips and a few screws.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, cloned BCM in the same location. Securely reconnect all the electrical connectors.
- Reassemble and Reconnect: Reinstall any trim panels you removed and, finally, reconnect the negative battery terminal.
- Post-Installation Checks: Start the vehicle and test all functions: lights, locks, windows, wipers, etc. Note that some vehicles may require a post-installation relearn procedure for the brake pedal position sensor or airbag system, as detailed in our FAQs below.

Frequently Asked Questions
Frequently Asked Questions
How does the Cloning Service work?
After you place your order, you will send us your original BCM. We use specialized equipment to read the unique vehicle data (including VIN, mileage, and key information) from your module and write it directly onto the replacement unit. This makes the new module an exact electronic copy of your old one, ensuring seamless integration with your vehicle.
Do I need to provide my VIN?
Yes, while we clone the data from your original module, we also use your VIN to verify the correct hardware and to load the latest GM software updates onto your replacement BCM before cloning. This ensures optimal performance and reliability.
What happens to my old BCM?
Your original module is always returned to you along with the programmed replacement unit. We do not keep your original part.
Will I need to perform any procedures after installation?
In most cases, no. However, on some models, you may need to perform additional relearn procedures. If your airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. A ‘Brake Pedal Position Relearn’ may also be required for proper brake light and traction control operation. Always consult a factory service manual for specifics.
Is this a guaranteed fix for my vehicle’s problems?
This BCM will resolve issues directly caused by a faulty module. However, vehicle electronics are complex. It’s crucial to ensure the problem has been properly diagnosed. Issues like bad wiring, faulty sensors, or poor grounds can mimic BCM failure. We guarantee the function of our module, but cannot guarantee it will fix problems unrelated to the BCM itself.
