Restore Full Electronic Functionality to Your GM Vehicle
Is your 2007-2012 GMC Acadia experiencing bizarre electrical problems? Flickering lights, malfunctioning power windows or door locks, or a security system that acts on its own are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and unpredictable issues. This direct-fit Body Control Module, part number 15819552, is the definitive solution to restore your vehicle’s performance and reliability.
From the Diagnostic Bay
We had a 2011 Acadia come into the shop with a laundry list of complaints from the owner. The dome lights would stay on, the driver’s side power window worked intermittently, and the radio would randomly shut off. The owner had already replaced the battery and checked fuses with no luck. After connecting our diagnostic scanner, we saw multiple communication error codes pointing towards the BCM. Instead of a dozen separate problems, it was one faulty module creating all the chaos. We installed a VIN-programmed BCM, and like magic, all the gremlins were gone. It’s a perfect example of how one central component can affect so many seemingly unrelated systems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Intermittent or complete failure of the radio and infotainment system.
- ✔ False alarms from the security system or issues with the keyless entry remote.
- ✔ Warning lights appearing on the dashboard without a clear cause.
- ✔ Battery drain issues caused by the BCM not properly shutting down accessories.
- ✔ Communication errors with other vehicle modules, leading to a no-start condition in severe cases.
The Superior Solution: A Pre-Programmed Acadia Body Control Module
Replacing a BCM isn’t just a simple swap. A new module from the dealership requires expensive programming and calibration tools to sync it with your vehicle’s unique VIN and specific options. Our process eliminates that hassle and cost. When you purchase this Acadia Body Control Module, we handle the critical programming for you. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash the module with the latest official GM software updates specific to your Acadia. This ensures that when the part arrives, it’s a true plug-and-play installation, saving you a trip to the dealer and hundreds of dollars in labor and programming fees.
Installation and Post-Install Procedures
While this module is designed for a straightforward installation, some vehicle systems may require a recalibration or sync procedure after the new BCM is connected. These are standard steps that a professional technician or savvy DIYer with a capable scan tool can perform.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed. This syncs the new BCM with the airbag system’s Supplemental Deployable Module (SDM). This is only necessary if the light is on.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration. This ensures the brake lights and traction control systems function as intended with the new module.
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 the Body Control Module do on my Acadia?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and the radio. When it fails, these systems can become unreliable.
Why is VIN programming so important for a BCM?
Programming the BCM with your vehicle’s VIN is critical because it allows the module to communicate with other computers in your car (like the engine and transmission controllers) and configures it for the specific options your vehicle has (like a sunroof or premium sound system). Without proper programming, the part will not function correctly.
How do I provide my VIN for programming?
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 order until we receive this information, as the programming is a necessary part of the fulfillment process.
Is this a difficult part to install myself?
For someone with moderate mechanical experience, the physical replacement is typically straightforward. The BCM is usually located under the dashboard on the driver’s side. However, be aware of the potential need for post-installation procedures, like an airbag system sync or brake pedal position relearn, which may require a professional-grade scan tool.
Will this fix my specific electrical problem?
This module will resolve issues directly caused by a faulty BCM. While the symptoms listed are common indicators of BCM failure, we always recommend a proper diagnosis by a qualified technician to confirm the BCM is the root cause before ordering.
