Restore Full Electrical Function to Your GM Truck or SUV
Are you battling a host of strange and frustrating electrical issues in your 2012-2014 GM vehicle? Problems like flickering lights, malfunctioning power windows and locks, or a security system that has a mind of its own often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it starts to fail, it can create a cascade of seemingly unrelated problems. This replacement BCM, part number 22737275, is the definitive solution to restore your vehicle’s systems to factory-perfect operation.

This ensures that the BCM is ready for installation the moment it arrives at your door, integrating seamlessly with your truck’s existing systems and options. This is a direct-fit replacement for part numbers 22737275, 22846365, and 22846364.
Is Your 2012-2014 GM Truck BCM Failing?
A faulty Body Control Module can manifest in numerous ways. If you’re experiencing any of the following symptoms, a failing BCM is the likely cause:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) that stay on, flicker, or don’t work at all.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ Horn sounding randomly or not working when pressed.
- ✔ Dashboard warning lights illuminating without a clear cause.
- ✔ Wipers operating intermittently or at incorrect speeds.
- ✔ Communication issues with other vehicle modules, leading to diagnostic trouble codes.
Installation and Post-Install Procedures
This BCM is typically located under the driver’s side of the dashboard, near the steering column. While the physical installation is straightforward for a DIY mechanic, some vehicles may require additional electronic relearn procedures after the new module is installed. 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 must be performed with a professional-grade scan tool. 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 brake light and traction control functionality.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls and monitors most of your vehicle’s non-engine-related electronic functions. This includes power windows, locks, lights, wipers, security system, and more. It’s the brain for your truck’s body accessories.
Do I need to take my truck to the dealer for programming?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. This means it arrives ready to be installed, saving you the time, hassle, and expense of a dealership visit.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it. You can typically find your VIN on the driver’s side dashboard (visible through the windshield) or on your vehicle’s registration.
What if the airbag light comes on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional scan tool to resolve this.
Is this a difficult part to install myself?
The physical replacement is generally straightforward for those with some mechanical experience. The BCM is located under the steering column. The main challenge can be the potential need for post-installation electronic relearn procedures, which may require a high-end scan tool.
