Restore Full Functionality to Your GM Vehicle
Is your 2007-2012 GMC Acadia, or another compatible GM vehicle, suffering from baffling electrical issues? Problems like flickering lights, malfunctioning power windows and locks, erratic dash warnings, or a security system that won’t cooperate are often symptoms of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and unpredictable problems. Don’t let a faulty module compromise your vehicle’s safety and convenience. This direct-replacement Body Control Module, part number 15948438, is the reliable, plug-and-play solution you need.
From the Diagnostic Bay
We once had a 2011 GMC Acadia come into the shop with a classic ‘parasitic draw’ issue. The owner had replaced the battery twice in six months, but it would still be dead every few mornings. Standard tests on the alternator and battery checked out fine. After hours of tracing circuits, we isolated the draw to the BCM. It wasn’t fully going to ‘sleep’ when the vehicle was off, causing a slow but steady drain. Replacing the BCM solved the problem completely. It’s a reminder that what seems like a simple battery issue can often be a deeper electronic problem originating from a faulty control module.
Is Your Vehicle Exhibiting These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Warning lights (like the airbag or ABS light) appearing on the dashboard for no reason.
- ✔ Wipers behaving erratically or not parking in the correct position.
- ✔ HVAC (heating and air conditioning) controls not responding.

Post-Installation Procedures
While this module is programmed for your vehicle, some GM platforms require simple relearn procedures after installation to ensure all systems communicate correctly. These are standard procedures for this type of repair.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This is because the new BCM needs to be electronically ‘introduced’ to the airbag’s SDM (Sensing and Diagnostic Module). A professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure to sync the modules and clear the light.
- Brake Pedal Position Relearn: To ensure proper function of your brake lights and traction control system, a brake pedal position sensor recalibration might be necessary. This can often be done with a high-end diagnostic tool.
Please Note: Specific procedures can vary by vehicle. We always recommend consulting a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to send you my old BCM?
No. This purchase has no core charge. You can keep your original module, which can be helpful for diagnostic reference if needed.
Why do you need my VIN?
Your vehicle’s VIN is essential for us to program the Body Control Module correctly. It allows us to load the specific software and settings that match your vehicle’s factory-installed options, ensuring seamless integration and functionality.
Is this a plug-and-play part?
Yes, this module is programmed to be as close to plug-and-play as possible. However, as noted above, some vehicles may require additional relearn procedures (like for the airbag or brake pedal sensor) with a professional scan tool to finalize the installation and clear any warning lights.
Will this fix my specific electrical problem?
This BCM will correct issues directly caused by a faulty Body Control Module. While the symptoms listed are very common indicators of BCM failure, we always recommend a proper diagnosis by a qualified technician to rule out other potential causes like wiring faults or sensor failures.
Where is the BCM located on a 2007-2012 GMC Acadia?
On the 2007-2012 GMC Acadia, the Body Control Module is typically located on the left-hand (driver’s) side of the dashboard, often up under the dash near the steering column or behind the instrument panel cluster.
