Is Your GM Vehicle Acting Possessed?
Are you dealing with flickering lights, power windows with a mind of their own, a security system that won’t cooperate, or random warning lights on your dash? These aren’t just annoyances; they are classic symptoms of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from your interior lights and power locks to your anti-theft system. When it starts to fail, it can create a cascade of confusing and frustrating electrical problems.
Don’t let electrical gremlins take over your vehicle. This is a direct-replacement Body Control Module, part number 22915542 (also interchangeable with 22820314), for a wide range of 2013-2019 GM vehicles. The best part? We handle the programming for you. Simply provide your vehicle’s VIN at checkout, and we will flash the module with the latest GM software specific to your car, truck, or van. This critical step ensures a smoother installation process, getting you back on the road with confidence.
From the Diagnostic Bay
We had a 2015 Chevy Traverse come in that was driving the owner crazy. The radio would turn off randomly, the dome lights would stay on, and the key fob worked only intermittently. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication errors all pointing back to one component: the BCM. Instead of a complex and costly wiring chase, we installed a VIN-programmed BCM. In under an hour, all the strange electrical issues were gone. It’s a perfect example of how this single module can restore order to a vehicle’s entire electronic ecosystem.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, and mirrors.
- ✔ Erratic instrument cluster behavior, including gauges that don’t work or warning lights that stay on.
- ✔ Headlights, taillights, or interior lights that flicker, stay on, or won’t turn on at all.
- ✔ Malfunctioning keyless entry and security system.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Communication errors with other vehicle modules, leading to a no-start condition in some cases.

Installation and Post-Install Procedures
While this module is designed for a straightforward installation, some vehicles may require additional steps after the part is physically installed. These are known as relearn or synchronization procedures. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade diagnostic tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Specific procedures can vary by vehicle. We always recommend consulting a factory service manual or a qualified automotive technician for guidance.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors most of the non-engine related electronic functions. This includes power windows, locks, lights, wipers, security systems, and more. It acts as a central hub for these systems.
How do I know for sure that my BCM is the problem?
While the symptoms listed are strong indicators, a definitive diagnosis often requires a professional scan tool to check for specific BCM-related trouble codes (DTCs). Common signs are multiple, unrelated electrical issues occurring simultaneously.
Is this part difficult to install?
The physical replacement is typically straightforward, often located under the dashboard on the driver’s side. However, some vehicles may require post-installation procedures like an airbag system sync or brake pedal relearn, which need a professional diagnostic tool.
What information do you need from me to program the module?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN). Please provide it during checkout to ensure we can program the BCM with the correct software and calibrations for your specific vehicle.
What happens if my airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the vehicle’s airbag module (SDM). A qualified technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
