Is Your GM Truck or SUV Plagued by Electrical Gremlins?
Are you dealing with flickering lights, power windows that have a mind of their own, or a security system that randomly goes off? These frustrating and unpredictable electrical issues often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of bizarre problems that are difficult to diagnose. Don’t let a faulty module keep you guessing. This VIN-programmed BCM is the direct, reliable solution to restore your vehicle’s functionality and your peace of mind.
We had a 2013 Silverado 2500 come into the shop with a complaint that was driving the owner crazy. The radio would turn on and off by itself, the dome lights would flicker while driving, and occasionally, the truck would refuse to start, showing a ‘Service Theft Deterrent System’ message. We checked the battery, alternator, and all the main grounds, but everything tested fine. After connecting our diagnostic scanner, we saw multiple communication loss codes with various modules, all pointing back to the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed a VIN-programmed unit just like this one. The installation took less than an hour, and all the strange electrical issues were gone instantly. It was a straightforward fix that saved the customer hundreds of dollars and a lot of frustration.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system or keyless entry malfunctioning.
- ✔ Warning lights on the dashboard appearing for no reason.
- ✔ Radio or climate control systems acting erratically.
- ✔ A ‘no-start’ condition due to the anti-theft system not recognizing the key.
- ✔ Inaccurate gauge readings on the instrument cluster.
The Direct Solution for Your 2012-2013 Yukon XL 2500 BCM

Simply provide us with your Vehicle Identification Number (VIN) during checkout, and our technicians will flash the unit with the latest GM-certified software and calibrations that match your truck’s exact options. This ensures a seamless installation process. This module is a direct replacement for part numbers 22846365, 22737275, and 22846364, covering a wide range of GM trucks and SUVs.
Installation and Post-Install Procedures
The BCM is typically located under the driver’s side of the dashboard, near the steering column. While the physical replacement is straightforward for a DIYer with basic tools, some post-installation steps may be necessary depending on your vehicle’s specific configuration.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure proper operation of the brake lights and stability control systems.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, security system, and climate controls.
Do I need to program this BCM?
No. This BCM comes pre-programmed to your vehicle’s VIN. You must provide your VIN at the time of purchase so we can load the correct software and calibrations before shipping it to you. This makes the installation process much simpler.
Where is the BCM located on my 2012-2014 GM truck or SUV?
The BCM is generally located under the driver’s side dashboard, attached to or near the steering column. It’s a black plastic box with multiple large electrical connectors.
What happens if I don’t provide my VIN?
We cannot ship the module without your vehicle’s VIN. The programming is essential for the BCM to function correctly with your specific truck or SUV’s features and security system. Your order will be held until a VIN is provided.
Is any other setup required after installation?
In most cases, the module is ready to go. However, as noted, some vehicles may require an airbag system sync or a brake pedal position relearn if specific warning lights appear after installation. These procedures require a professional-grade diagnostic tool.
