Restore Full Functionality to Your GM Vehicle with a VIN-Programmed BCM
If your 2009-2012 Chevrolet Traverse is suffering from a plague of bizarre electrical issues—like power windows with a mind of their own, a security light that won’t turn off, or interior lights that flicker randomly—the root cause is very likely a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can make driving frustrating and unpredictable. This isn’t just an inconvenience; it can affect safety systems and leave you stranded. This replacement BCM is your reliable, direct-fit solution, arriving pre-programmed with the latest GM software for your specific vehicle.
A Technician’s Notebook: The Case of the Confused Crossover
I remember a 2011 Traverse that rolled into my bay with a laundry list of complaints from the owner. The key fob worked intermittently, the radio would shut off randomly, and the “Service StabiliTrak” message kept popping up. A scan showed a slew of communication codes (U-codes) pointing to a network issue. After checking the main power and ground connections, all signs pointed to an internal BCM failure. In the past, this meant a new module plus a tow to the dealership for expensive programming. With this VIN-programmed module, we had the customer back on the road the same afternoon, saving them time, money, and a major headache. It’s the most efficient fix for these common GM platform issues.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s time to consider a replacement:
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The anti-theft or security light stays on, preventing the engine from starting.
- ✔ Key fobs are not recognized or work sporadically.
- ✔ The instrument cluster displays incorrect information or warning lights (e.g., Service Airbag, StabiliTrak).
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0100, U0140, or other U-series codes.
- ✔ Wipers, horn, or radio functions are intermittent or have failed completely.
A Straightforward Guide to Installation
Installing your new BCM is a manageable task for a confident DIYer. Our pre-programming service eliminates the need for dealer-specific tools for software flashing, which is often the biggest hurdle. For a 2009-2012 Traverse, the BCM is typically located on the left-hand (driver’s) side of the dash.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to discharge completely.
- Locate the BCM: On the Traverse, Acadia, and Enclave, you’ll usually find the BCM under the driver’s side dashboard, often near the steering column or kick panel.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old module. They have locking tabs that must be depressed to be released. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely plug in all the electrical connectors. Ensure they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position (without starting the engine) and test all body functions: lights, locks, windows, radio, etc.
- Perform Relearn Procedures: As noted below, you may need to perform a couple of simple relearn procedures. If the airbag light is on, a professional scan tool is required to sync the SDM.
Important Post-Installation Steps
While our programming handles the heavy lifting, some GM vehicles require a final handshake between modules after installation. Depending on your specific model and options, you may need to address the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible professional scan tool. This ensures the new BCM and the airbag system are correctly communicating.
- Brake Pedal Position Relearn: To ensure accurate brake light operation and proper function of the traction/stability control systems, a brake pedal position sensor relearn may be required.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any part of the process.

Do I need to send my old BCM back?
Do I need to send my old BCM back?
No, there is absolutely no core charge for this part. You can keep your original module, which can be helpful for reference or if you ever need to revert to the original part for any reason.
Is this a plug-and-play part?
Yes, for the most part. We program the module to your vehicle’s VIN before shipping, which handles the most complex part of the replacement. However, as mentioned, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor after installation.
How do I provide my VIN?
After you complete your purchase, we will contact you to request your vehicle’s 17-digit VIN. We cannot program and ship your BCM without this information, so please have it ready.
Will this fix my ‘Service Airbag’ light?
If the airbag light is caused by a faulty BCM, this part will resolve the root cause. However, after installation, the light will likely remain on until the ‘Setup SDM Primary Key in BCM’ procedure is performed with a professional-grade scan tool to sync the modules.
What if my original part number isn’t 15921353?
This module is a direct replacement for a long list of GM part numbers. Please check the fitment list on this page to see if your original part number is included. As long as it’s on the list, this module will work perfectly.
