Are you battling frustrating electrical gremlins in your Chevrolet Traverse? Seemingly random issues like flickering lights, malfunctioning power windows, or a battery that dies overnight are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s comfort and convenience features. When it fails, it can cause a cascade of confusing problems. This VIN-programmed Body Control Module is the definitive solution, designed to restore your vehicle’s electronic functions to factory specifications without a trip to the dealership.
From the Diagnostic Bay
We had a 2011 Traverse come in that was driving the owner crazy. The dome lights would randomly turn on while driving, the power locks would cycle on their own, and the battery would be dead every other morning. The owner had already replaced the battery and alternator. After hooking up our diagnostic scanner, we saw multiple communication errors pointing towards the BCM. A faulty BCM was causing a parasitic draw. We installed a VIN-programmed module just like this one, and all the bizarre electrical issues were gone instantly. It’s a common failure point, but thankfully, it’s a straightforward fix with the right part.
Common Symptoms of a Failing 2009-2012 Traverse BCM
If your vehicle is experiencing any of the following issues, a faulty BCM is the most likely culprit. Replacing it with our pre-programmed unit can resolve these problems and get your Traverse operating reliably again.
Signs of BCM Failure:
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) flickering, staying on, or failing to turn on.
- ✔ The security system acting up, causing false alarms or preventing the engine from starting.
- ✔ Instrument cluster gauges behaving strangely or warning lights (like the airbag light) illuminating without reason.
- ✔ Unexplained parasitic battery drain that leads to a dead battery, often overnight.
- ✔ Windshield wipers turning on by themselves or not responding to controls.

Important Post-Installation Information
While this module is programmed to your VIN for a simple installation, some GM vehicles may require additional steps after the part is installed. These are known as ‘relearn’ or ‘setup’ procedures and may require a professional scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure proper brake light and traction control function.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What does the Body Control Module (BCM) do on my Traverse?
The BCM is a computer that controls most of your vehicle’s non-engine related electronics. This includes power windows, locks, lights, wipers, security system, and instrument cluster functions.
Is this module difficult to install?
The physical installation is typically straightforward, often located under the driver’s side dashboard. Because we pre-program the module to your VIN, you avoid the most difficult step, which is software flashing. However, some vehicles may require a simple relearn procedure after installation as noted above.
How do I provide my vehicle’s VIN?
You can add your 17-digit VIN to the notes section during checkout or reply to your order confirmation email with the information. We cannot ship your part until we receive the VIN.
Do I need to send my old BCM back?
No. This product has no core charge. You can keep your original module.
My original part number isn’t 15276271. Will this work?
Yes. This BCM is a compatible replacement for all the part numbers listed in the description. As long as your vehicle is listed in the fitment chart, this module will work when programmed to your VIN.
