Is Your Chevrolet Traverse Experiencing Bizarre Electrical Problems?
If your 2009-2012 Traverse is acting possessed—with flickering lights, malfunctioning power windows, a dead instrument cluster, or random warning lights—the culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated issues. Don’t let a faulty BCM keep you off the road. This direct-replacement Body Control Module is the solution you need to restore full functionality and peace of mind.
From the Diagnostic Bay
We recently had a 2011 Traverse come into the shop with a complaint the customer described as “Christmas lights on the dash.” The security light was on, the radio would cut out, and the power locks worked intermittently. After checking the basics like the battery and grounds, our scan tool pointed to a communication failure with the BCM. Instead of sending the customer to the dealership for an expensive replacement and programming, we installed one of our pre-programmed modules. The entire process was done in the bay, and the vehicle was back to normal in under an hour, saving the customer significant time and money.
Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, locks, or mirrors not working correctly.
- ✔ The security system acting up or preventing the car from starting.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Unresponsive key fob or push-to-start system.
- ✔ False warning lights illuminating on the dashboard (e.g., ABS, Airbag).
- ✔ Rapid battery drain while the vehicle is parked.
The Plug-and-Play Solution: A Pre-Programmed 2009-2012 Traverse Body Control Module
The biggest hurdle in replacing a BCM is the need for expensive, dealer-specific programming. We eliminate that step entirely. When you order from us, you provide your vehicle’s VIN, and we program the module with the latest GM-certified software specifically for your Traverse. This ensures that the BCM communicates perfectly with your vehicle’s other computers right out of the box. This is a complete, ready-to-install solution that saves you a trip to the dealership and costly programming fees.
This module is a direct fit for part number 15299986 and is also compatible with a wide range of other GM part numbers, including: 10382479, 15093910, 15276271, 15819552, 15828601, 15837419, 15872388, 15872421, 15880684, 15921352, 15921353, 15948438, 15948439, 20815898, 20839063, 20864767, 20864768, 20921435, 20921436, 20935349, 22860591, 25826124, 25826125, 25847588, 25847589, 25892622, 25910474, 25934762, 25934763, and 95151084.
Installation and Required Procedures
Physical installation is typically straightforward, involving disconnecting the battery and swapping the old module with the new one. However, after installation, certain vehicle systems may require a relearn procedure to sync with the new BCM. While our programming handles the critical functions, you or your mechanic may need a capable scan tool to perform the following:
- 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 airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a recalibration of the brake pedal position sensor might be needed to ensure proper function of the brake lights and stability control systems.
Always consult a factory service manual for your specific vehicle for detailed instructions.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. This is the primary benefit of our service. We pre-program the module to your vehicle’s specific VIN before we ship it. This means it’s ready for installation upon arrival, saving you hundreds in dealership programming fees.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive and validate your VIN.
What if the airbag light comes on after I install it?
This is a common occurrence. The new BCM needs to be electronically introduced to the vehicle’s airbag computer (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to turn off the light.
Is this a plug-and-play part?
It is ‘plug-and-program-and-play’. We handle the programming, so you can handle the installation. While it will work immediately for most functions, some simple relearn procedures, like for the airbag or brake sensor, may be required depending on your exact model and options.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module, so you won’t have to worry about the cost or hassle of shipping it back.
