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 won’t cooperate? These frustrating and seemingly random 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, managing everything from your interior lights and power locks to your instrument cluster and security features. When it starts to fail, it can create a cascade of confusing and annoying problems.
The Direct Solution: A VIN-Programmed BCM
Don’t let a faulty module keep your truck off the road or make your daily drive a hassle. This Body Control Module, part number 22846365, is the definitive solution for a wide range of 2012-2014 GM trucks and SUVs. The best part? We take the guesswork and dealership expense out of the equation. Simply provide us with your vehicle’s VIN during checkout, and we will program the module with the latest GM software specific to your exact vehicle configuration. This ensures a seamless installation process and restores your vehicle’s electronics to factory-perfect operation.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors not working correctly or at all.
- ✔ The security system or keyless entry failing to operate properly.
- ✔ Warning lights appearing on the dashboard for no apparent reason.
- ✔ Intermittent issues with the radio, climate control, or instrument cluster.
- ✔ A parasitic battery drain that leaves you with a dead battery.
Installation and Post-Install Steps for Your GM Truck Programmed BCM
This BCM is located under the steering column and is designed for a direct-fit replacement. Once you receive your VIN-specific GM Truck Programmed BCM, the physical installation is straightforward. However, due to the complexity of modern vehicle systems, a couple of post-installation procedures may be required to ensure all systems communicate correctly.
Important Post-Installation Information:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your vehicle’s airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control functionality.
We always recommend consulting a factory service manual or a qualified technician for specific guidance related to your vehicle.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security systems, and more, ensuring all these comfort and convenience features work together.
Is this BCM truly plug-and-play?
Because we program it to your specific VIN before shipping, it is as close to plug-and-play as possible. It eliminates the need for expensive dealership programming. However, as noted, some vehicles may require minor relearn procedures (like for the airbag or brake sensor) with a scan tool after installation.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot ship your part until we receive the VIN.
What happens if my airbag light is on after I install it?
This is a known possibility. It simply means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A qualified mechanic with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No. This part has no core charge, so you can keep your original module.
