Is Your GM Truck or SUV Experiencing Strange Electrical Issues?
If your 2012-2014 Chevrolet Tahoe, Silverado, GMC Sierra, or other compatible GM vehicle is acting possessed, the Body Control Module (BCM) is a likely culprit. As the central nervous system for your vehicle’s electronics, a failing BCM can cause a cascade of frustrating and seemingly unrelated problems. From flickering lights and malfunctioning power windows to false security alerts and starting issues, these symptoms point directly to the electronic hub located under your steering column. Don’t let a faulty module compromise your vehicle’s functionality and safety. This is a direct replacement, VIN-programmed solution to get your truck back in perfect working order.
From the Diagnostic Bay
We had a 2013 Silverado 2500 in the shop that was driving the owner crazy. The dome lights would stay on, the radio would randomly shut off, and the power door locks worked only when they wanted to. He had already replaced the battery and checked all the fuses. After hooking up our diagnostic scanner, we saw multiple communication error codes across different systems, all pointing back to one central point: the BCM. A failing BCM can send confusing signals throughout the vehicle, making diagnosis a nightmare for the uninitiated. We installed a VIN-programmed BCM, and like magic, all the bizarre electrical gremlins vanished. This is a common story, and a pre-programmed module is the most efficient fix.
Symptoms of a Failing Body Control Module
- ✔ Intermittent or non-working power windows, door locks, and mirrors.
- ✔ Erratic interior or exterior lights (flickering, staying on, or not turning on at all).
- ✔ Malfunctioning windshield wipers or horn.
- ✔ The security system engaging randomly or a persistent “Service Theft Deterrent System” message.
- ✔ Instrument cluster gauges behaving erratically or warning lights appearing for no reason.
- ✔ Radio or infotainment system randomly turning on or off.
- ✔ Key fob not working correctly for locking, unlocking, or remote start.
- ✔ Vehicle failing to start or experiencing parasitic battery drain.
The Plug-and-Play Solution for Your 2012-2014 Tahoe BCM
Forget expensive dealership visits and the hassle of finding a shop capable of programming a new module. We provide a simple, effective solution. When you purchase this BCM, you provide us with your vehicle’s VIN. Our technicians then flash the module with the latest GM-certified software specific to your exact vehicle configuration. This ensures that all the options and features your truck came with from the factory will work correctly right out of the box. This BCM, part number 22846364, is a direct replacement for part numbers 22737275 and 22846365, covering a wide range of GM trucks and SUVs including the Silverado, Sierra, Suburban, Yukon, and Escalade.
Installation and Post-Install Procedures
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-savvy owner, there are a couple of potential post-installation steps to be aware of. Because the BCM communicates with nearly every other module, some systems may need to be re-synced after installation.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a “Setup SDM Primary Key in BCM” procedure is required. This must be done with a professional-grade scan tool to ensure the BCM and the airbag system (SDM) are properly communicating for safety.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary. This ensures your brake lights and traction control system function as intended.
Best of all, there is no core charge. You can keep your original module without the hassle of shipping it back.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide your vehicle’s VIN at checkout, and we will flash the module with the latest GM software for your specific vehicle.
Where is the BCM located on my 2013 GMC Sierra?
On most compatible models, including the 2013 GMC Sierra, the BCM is located under the driver’s side dashboard, typically attached to a bracket near the steering column.
What happens if I forget to provide my VIN?
We cannot program or ship your BCM without a valid VIN. The programming is essential for the module to function correctly in your vehicle. We will contact you to retrieve the VIN if it is not provided with your order.
Will this fix my “Service Airbag” light?
If the airbag light is on due to a fault within the original BCM, this replacement part will solve the root cause. However, you will still need to perform the “Setup SDM Primary Key in BCM” procedure with a capable scan tool to sync the new BCM with the airbag system and clear the light.
