Restore Full Electrical Function to Your GM Truck or SUV
Is your 2012-2014 Suburban, Silverado, Sierra, or other GM vehicle plagued by bizarre electrical problems? Inconsistent power windows, malfunctioning door locks, erratic interior lights, or a dead battery are 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 cause a cascade of frustrating issues. This direct-fit replacement BCM, part number 22846364, is the definitive solution to restore your vehicle’s functionality and reliability.
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 wouldn’t turn off with the door open, and the power locks worked only when they wanted to. The owner had already replaced the driver’s door switch and checked countless fuses. After hooking up our scanner, we saw communication faults pointing directly to the BCM. Instead of a complex diagnostic chase, the root cause was a faulty central module. Installing a VIN-programmed BCM like this one resolved all the issues in under an hour, saving the customer from further guesswork and expense.
Common Symptoms of a Failing BCM
- ✔ Power windows, mirrors, or seats operating intermittently or not at all.
- ✔ Interior or exterior lights staying on or not turning on correctly.
- ✔ Malfunctioning keyless entry and power door locks.
- ✔ Security system faults or alarm sounding unexpectedly.
- ✔ Dashboard warning lights appearing without a clear cause.
- ✔ Unexplained battery drain, leading to a no-start condition.
- ✔ Radio or infotainment system behaving erratically.
Solving Your 2012-2014 Suburban BCM Issues
Don’t let a faulty BCM disrupt your driving experience. Our process is designed to be simple, effective, and get you back on the road quickly. Unlike the dealership, which requires costly programming and multiple appointments, our BCM arrives at your door ready for installation. We flash the module with the latest GM software updates using the VIN you provide at checkout. This ensures perfect compatibility with your vehicle’s specific options and systems. This is a true plug-and-play solution for the savvy DIYer or professional technician.
Installation and Post-Install Considerations
The BCM is typically located under the driver’s side of the dashboard, near the steering column. Installation involves disconnecting the battery, removing a few trim panels for access, and swapping the electrical connectors from the old module to the new one.
Important: While this module is pre-programmed, certain vehicle systems may require a relearn or synchronization procedure after installation. Please note 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 operation.
We make the process easier with a No Core Charge policy, so you can keep your original module without the hassle of returning a core.
This module is a direct replacement for part numbers 22737275, 22846365, and 22846364, and fits a wide range of GM trucks and SUVs from 2012-2014, including the Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche, and Escalade. Please verify your part number and check the fitment list to ensure compatibility.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related functions. This includes power windows, locks, lights, security system, wipers, and other interior electronic features.
Is this module difficult to install?
For someone with basic mechanical skills, the installation is straightforward. The BCM is located under the driver’s side dashboard. The main challenge is accessing it. The key benefit of our product is that the difficult programming step is already done for you.
Do I need to have this BCM programmed?
No. This is the primary benefit of our service. You provide us with your vehicle’s VIN during checkout, and we program the module specifically for your vehicle before shipping it. It arrives ready to install.
What if my airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag’s Sensing and Diagnostic Module (SDM). A professional technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
How do I provide my VIN?
You will be prompted to enter your vehicle’s 17-digit VIN during the checkout process. Please double-check it for accuracy, as the programming is based entirely on this number.
Does this part fit models other than the Suburban?
Yes, absolutely. This BCM fits a wide array of 2012-2014 GM trucks and SUVs, including the Silverado, Sierra 1500/2500/3500, Tahoe, Yukon, Escalade, and Avalanche. Please refer to the detailed fitment list on this page.
