Is Your GM Truck or SUV Experiencing Electrical Gremlins?
If your 2012-2014 Yukon, Sierra, Silverado, or other compatible GM vehicle is suffering from strange and unpredictable electrical problems, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central hub for your vehicle’s body electronics, managing everything from your power windows and door locks to your interior lighting and security system. When it starts to fail, it can cause a cascade of frustrating issues that can be difficult to diagnose.
The Simple Solution for a Complex Problem
Instead of a costly trip to the dealership for diagnostics and programming, we offer a direct, effective solution. This BCM, part number 22846364 (also compatible with 22737275 and 22846365), arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We flash it with the latest GM software updates, ensuring optimal performance and compatibility. This means no expensive programming tools or dealer appointments are required—it’s prepared for installation right out of the box.
From the Diagnostic Bay
We had a 2013 Sierra 2500 in the shop that was driving the owner crazy. The dome lights would flicker randomly, the driver’s side power window would only work intermittently, and the radio would sometimes refuse to turn off after the key was removed. The owner had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication errors pointing towards the BCM. We installed one of our pre-programmed modules, and instantly, all the electrical gremlins vanished. It’s a classic case where the central computer just gets tired, and a direct replacement is the only true fix.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, not turning on, or flickering.
- ✔ The security system or keyless entry malfunctioning.
- ✔ Dashboard warning lights appearing for no reason (e.g., ABS, Airbag, Traction Control).
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Wipers behaving erratically or not parking in the correct position.
- ✔ Communication issues with other vehicle modules.
Installation and Post-Install Considerations for your 2012-2014 Yukon Body Control Module
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, there are a couple of potential post-installation procedures to be aware of. Because this module communicates with nearly every system in your vehicle, some systems may require a ‘handshake’ with the new BCM.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: In some cases, the brake pedal position sensor may need to be recalibrated to ensure proper brake light operation and to satisfy the traction control system.
We handle the most critical step—the programming—before we ship. Just provide your VIN during checkout, and we’ll take care of the rest, saving you hundreds of dollars and significant hassle. Restore your vehicle’s electronic functions and drive with confidence again.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before shipping it to you. It arrives ready for installation, saving you the time and expense of a dealership visit.
Where is the BCM located on my 2013 GMC Sierra?
The Body Control Module is located under the driver’s side dashboard, typically attached to a bracket near the steering column.
What information do you need from me?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. This allows us to flash the module with the correct software and vehicle-specific options.
What happens if my airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Is this part compatible with part number 22737275?
Yes, this BCM (22846364) is a direct replacement for part numbers 22737275 and 22846365, covering a wide range of GM trucks and SUVs from 2012 to 2014.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
