Restore Full Electronic Functionality to Your GM Vehicle
Are you experiencing frustrating electrical issues in your GMC Acadia, Chevy Traverse, or other compatible GM vehicle? A faulty Body Control Module (BCM) is often the culprit behind problems like erratic power windows and locks, malfunctioning interior lights, or false security system alerts. The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing symptoms. This replacement Body Control Module, part number 15299986, is the reliable, straightforward solution to get your vehicle back in perfect working order.
We had a 2011 GMC Acadia come in with a classic case of “automotive poltergeist.” The radio would turn on and off by itself, the dome lights would flicker, and occasionally the power liftgate would refuse to open. The owner had already replaced the battery and checked the main fuses. After hooking up our diagnostic tool, we saw multiple communication error codes (U-codes) pointing to a network disruption. Instead of chasing individual components, we went straight to the central hub: the BCM. A quick inspection revealed signs of water intrusion on the old module’s casing—a common failure point. By installing a VIN-programmed BCM like this one, we resolved all the issues in a single repair, saving the customer time and the expense of replacing other perfectly good parts.
Common Symptoms of a Failing 2007-2012 Acadia BCM
If your vehicle is exhibiting any of the following signs, a failing BCM is the likely cause. This module is designed to correct these problems and restore your vehicle’s factory operations.
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Malfunctioning interior or exterior lighting (dome lights, headlights, taillights).
- ✔ Instrument cluster gauges behaving erratically or not working at all.
- ✔ The security system engaging randomly or preventing the car from starting.
- ✔ HVAC (heating and air conditioning) controls not responding.
- ✔ Communication errors with other vehicle modules, often resulting in multiple warning lights.
- ✔ Key fobs not working correctly.
Plug-and-Play Solution with VIN Programming
Don’t waste time and money at the dealership. We take the hassle out of the replacement process. When you purchase this BCM, simply provide us with your vehicle’s VIN during or after checkout. Our technicians will program the module with the latest GM software specific to your vehicle’s configuration. This ensures that when the part arrives, it’s ready for installation without the need for an expensive trip to a mechanic for programming. It’s a true plug-and-play solution.
Important Post-Installation Information
While this module is programmed for a straightforward installation, some vehicle systems may require a simple relearn procedure to sync with the new BCM. This is standard for many modern electronic repairs.
- Airbag System Sync: If your airbag warning light is illuminated 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: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control functionality.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and climate controls. It’s the command center for passenger comfort and convenience features.
How do I know if my BCM is failing?
Common symptoms include multiple, unrelated electrical issues happening at once. This can be flickering lights, malfunctioning power accessories, random warning lights on the dash, or key fob problems. A diagnostic scan showing communication codes (U-codes) is also a strong indicator.
Is this BCM difficult to install?
The physical installation is typically straightforward for someone with basic mechanical skills, often involving removing a few dash panels and unplugging the old module to plug in the new one. Since we program it to your VIN, you avoid the complex software setup, making it a much simpler job.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings your vehicle had when it left the factory. This ensures all features work correctly and that the module communicates properly with other computers in your car.
What happens if the airbag light comes on after installation?
This is a normal security measure. The new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A qualified technician with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync them and turn off the light.
Is there a core charge for this part?
No, there is no core charge. You can keep your old BCM without needing to send it back to us.
