Restore Full Electronic Control to Your GM Truck or SUV
Are you battling bizarre and frustrating electrical issues in your 2012-2014 GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts on its own, or warning lights that won’t go away are all classic 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 create a cascade of problems that are difficult to diagnose. This pre-programmed Body Control Module is the definitive solution to restore your vehicle’s functionality and get you back on the road with confidence.
From the Diagnostic Bay
We had a 2013 Silverado 2500 in the shop that was driving its owner crazy. The battery would be dead every other morning. He had already replaced the battery twice and the alternator once, but the parasitic drain persisted. After hours of tracing circuits, we isolated the issue to the BCM. It wasn’t fully going to ‘sleep’ when the truck was off, slowly draining the battery overnight. Installing a new, correctly programmed BCM didn’t just fix the battery drain; it also solved a quirky issue with the passenger-side power lock he hadn’t even mentioned. It’s a perfect example of how a single faulty module can cause multiple, seemingly unrelated problems.
Is Your GM Truck or SUV Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, a faulty Body Control Module is the likely culprit:
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ The security system or keyless entry system behaving erratically.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Dashboard warning lights (like the airbag light) staying on for no reason.
- ✔ Wipers or radio turning on and off by themselves.
- ✔ A persistent battery drain that leaves you with a dead battery.
- ✔ Communication errors with other vehicle modules when using a diagnostic scan tool.

Our technicians will flash the BCM with the latest, most stable software directly from GM, ensuring it is a perfect match for your vehicle’s specific configuration and options. This means that when the part arrives, it’s ready for installation right out of the box, saving you hundreds in dealer fees and vehicle downtime.
Installation Guide for Your GM Truck Body Control Module
This BCM is located under the driver’s side of the dashboard, near the steering column. While the physical replacement is straightforward for a DIY mechanic with basic tools, there are important post-installation steps to be aware of.
- Disconnect the Battery: Before beginning any work, disconnect the negative battery terminal to prevent electrical shorts.
- Locate and Remove the Old BCM: Access the module under the dash. Carefully disconnect all electrical connectors and unbolt the module from its mounting bracket.
- Install the New BCM: Mount the new module and securely reconnect all electrical connectors.
- Reconnect the Battery: Reattach the negative battery terminal.
- Perform Post-Install Procedures: After installation, your vehicle may require one or more relearn procedures to function correctly. This is normal.
Important Post-Installation Notes:
- 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: Some models may require a brake pedal position sensor recalibration to ensure proper operation of the brake lights and stability control systems.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.
Frequently Asked Questions
How does the VIN programming service work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the official GM database and load the correct software and calibration files for your specific truck or SUV onto the BCM before it ships.
Do I need to send my old BCM back?
No. This product has no core charge. You can keep your original module, which can be helpful for reference or if you ever need to revert to the original part.
Is this a simple plug-and-play installation?
For the most part, yes. Because we program it to your VIN, it eliminates the need for dealer programming. However, as noted, you may need a professional scan tool to perform an airbag system sync or brake pedal position relearn after installation.
What tools are required for this job?
You will need basic hand tools like a socket set and screwdrivers to access and replace the module. A professional-grade diagnostic scan tool may be necessary for the post-installation relearn procedures.
This module fits multiple part numbers. How do I know it’s the right one?
This BCM is a direct replacement for part numbers 22737275, 22846365, and 22846364. As long as your vehicle is on the fitment list and your original part number is one of these, this module will work perfectly once programmed to your VIN.
