Restore Full Functionality to Your GM Vehicle
Are you battling persistent and frustrating electrical issues in your GMC Acadia, Chevy Traverse, or Buick Enclave? Flickering lights, malfunctioning power windows, a security system that acts on its own, or warning lights that won’t turn off are common signs of 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 wide range of unpredictable problems. This replacement BCM, part number 22915542 (also compatible with 22820314), is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
We had a 2015 Chevy Traverse come in with the strangest set of symptoms. The customer said the radio would randomly change stations, the interior dome lights would flicker while driving, and the power locks would cycle on their own. They had already replaced the battery and checked the alternator, but the issues continued. A deep scan showed multiple communication errors pointing back to the BCM. Instead of a complex and costly wiring chase, we installed a VIN-programmed BCM. The moment it was connected and the relearn procedures were done, every single phantom electrical issue vanished. It’s a classic case where the central controller was the root cause of what seemed like a dozen unrelated problems.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Malfunctioning windshield wipers or washers.
- ✔ False alarms from the vehicle’s security system or keyless entry failure.
- ✔ Inoperative radio or climate control functions.
- ✔ Warning lights on the dashboard, such as the airbag or ABS light, with no apparent mechanical cause.
- ✔ Communication errors with other vehicle modules when scanned with a diagnostic tool.
Why Choose Our Programmed 2013-2017 Acadia BCM?
Replacing a BCM isn’t as simple as swapping out a fuse. A new module from the dealership requires expensive and time-consuming programming with specialized tools. Our solution eliminates that hassle. We take your vehicle’s Vehicle Identification Number (VIN) at the time of purchase and flash this module with the latest, most stable software directly from GM. This ensures the BCM is perfectly matched to your vehicle’s specific options and configuration. It arrives at your door ready for installation, saving you a trip to the dealer and hundreds of dollars in programming fees.
Installation and Post-Install Procedures
While this module is pre-programmed for your vehicle, some simple post-installation relearn procedures may be necessary to ensure all systems communicate correctly. This is a normal part of replacing a major electronic module. Specific requirements can vary by model, but common procedures include:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool must be used to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: To ensure accurate brake light operation and proper function of the traction control and stability systems, a brake pedal position sensor recalibration might be required.
We provide a plug-and-play solution that gets you 95% of the way there. These final sync procedures are standard for this type of repair and can be performed by any competent automotive shop or a DIYer with an advanced diagnostic tool. Always consult a factory service manual for your specific vehicle for detailed instructions.
Frequently Asked Questions
What does a Body Control Module (BCM) actually do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and climate controls, ensuring they all work together seamlessly.
Why is providing my VIN so important?
Your VIN allows us to program the BCM with the exact software and configuration for your vehicle’s specific features (like keyless entry, sunroof, specific lighting, etc.). This step is critical for ensuring the part works correctly right out of the box and avoids a trip to the dealership.
Is this part truly plug-and-play?
It is pre-programmed to your VIN, which handles the most complex part of the installation. However, as with any major module replacement, some vehicle systems may require a simple ‘relearn’ or ‘sync’ procedure with a diagnostic tool to fully integrate the new BCM. This is standard for this type of repair.
What if the airbag light comes on after I install it?
This is a common occurrence. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to sync the components and turn off the light.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
