Restore Control and End Electrical Chaos in Your GM Vehicle
Is your 2009-2012 Chevrolet Traverse acting possessed? Flickering dash lights, power windows with a mind of their own, intermittent starting issues, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating and unpredictable problems. This isn’t just an annoyance; it can affect vehicle security and safety systems. Stop chasing electrical gremlins and get the definitive, reliable solution.
This replacement Body Control Module, part number 15921352, arrives at your door fully programmed to your vehicle’s specific VIN. We load the latest, most stable software from GM, ensuring optimal performance and compatibility right out of the box. This eliminates the need for expensive dealership programming or specialized scan tools, saving you significant time and money. It’s the most direct path to restoring your vehicle’s proper function and your peace of mind.
Case Study: The Ghost in the Traverse
A customer brought in their 2011 Traverse with a list of bizarre symptoms. The radio would turn on and off, the driver’s side power window worked only when it wanted to, and the anti-theft system would occasionally prevent the car from starting. They had already replaced the battery and checked fuses, but the problems persisted. After connecting my diagnostic tool, I saw multiple communication error codes (U-codes) pointing to the BCM. Instead of a costly and time-consuming repair at the dealer, we ordered a VIN-programmed module. The installation was straightforward, and once connected, all the strange electrical issues vanished. It’s a common failure I’ve seen dozens of times on these GM platforms, and a pre-programmed 2009-2012 Traverse BCM is the most efficient fix.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays on, sometimes causing a no-start condition.
- ✔ Dashboard warning lights flicker or appear randomly.
- ✔ Communication error codes stored, such as U0140, U0155, or other U-series codes.
- ✔ Horn, wipers, or other accessories operate intermittently or not at all.
- ✔ Issues with the keyless entry system not responding.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to power down completely.
- ✔ Locate the BCM: On the 2009-2012 Chevrolet 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 in by clips or a few screws.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be pressed to release. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors, ensuring they click into place.
- ✔ Reconnect and Test: Reinstall any trim panels you removed. Reconnect the negative battery terminal. Turn the key to the ‘ON’ position (without starting) and test all body functions—windows, locks, lights, wipers, etc.—to confirm proper operation.
Important Post-Installation Steps
While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure brake lights and traction control function correctly. This also typically requires a capable diagnostic tool.

Frequently Asked Questions
Frequently Asked Questions
Do I need to do any programming myself?
No. We program the BCM to the VIN you provide during checkout. It will arrive ready to be installed, eliminating the need for a trip to the dealership for programming.
Is this a difficult part to install for a DIYer?
For someone with basic mechanical skills, this is a very manageable job. Accessing the module behind the dash is typically the most time-consuming part. Basic hand tools are all that’s required for the physical swap.
What is a core charge?
A core charge is a deposit that is refunded when you return your old part. We do not have a core charge on this item, so you can keep or dispose of your old module as you see fit.
What if the airbag light comes on after I install it?
This is a known possibility. The new BCM needs to be electronically introduced to the airbag module (SDM). This requires a bi-directional scan tool to perform the ‘Setup SDM Primary Key’ function. A local repair shop can typically perform this service for you.
Will this 2009-2012 Traverse BCM fix my no-start problem?
It can. A faulty BCM can activate the anti-theft system (Passlock/VATS) incorrectly, preventing the engine from starting. If your no-start issue is accompanied by a flashing security light, a failing BCM is a very likely cause.
What VIN do I need to provide?
Please provide the 17-digit Vehicle Identification Number from your vehicle’s dashboard (visible through the windshield) or driver’s side door jamb sticker. This ensures we load the exact correct software for your vehicle’s options.
