Is Your GM Truck or SUV Plagued by Electrical Gremlins?
Are you dealing with a frustrating array of electrical issues in your 2012-2014 GM vehicle? Do your power windows have a mind of their own? Do your lights flicker unexpectedly, or does your key fob refuse to work? These aren’t just random annoyances; they are classic symptoms of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from interior lighting and power locks to the security system. When it fails, it can create a cascade of confusing and unpredictable problems that can make your vehicle feel unreliable.
Ignoring a faulty BCM can lead to more than just inconvenience. A malfunctioning security system could leave you stranded, and erratic lighting can be a serious safety hazard. Instead of spending a fortune at the dealership on diagnostics, parts, and programming fees, take control of the repair with a reliable, pre-programmed solution.
Common Symptoms of a Failing BCM
A failing Body Control Module can manifest in numerous ways. If you’re experiencing several of the following issues, there’s a strong possibility your BCM is the culprit:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system acting up, displaying a “Service Theft Deterrent System” message, or preventing the engine from starting.
- ✔ Keyless entry remote (key fob) not working consistently or at all.
- ✔ Instrument cluster gauges behaving erratically or warning lights appearing for no reason.
- ✔ Radio, climate controls, or other interior accessories malfunctioning.
- ✔ Rapid battery drain while the vehicle is parked.

This module, part number 22846365, is a direct replacement for original part numbers 22737275, 22846365, and 22846364. It fits a wide range of GM trucks and SUVs, including the Chevrolet Silverado, Suburban, Tahoe, Avalanche, GMC Sierra, Yukon, and Cadillac Escalade models from 2012 to 2014. By getting a pre-programmed module, you skip the expensive trip to the dealership, avoid the risk of incompatible junkyard parts, and get your vehicle back to full functionality faster.
Installation and Post-Install Procedures
The BCM is typically located under the driver’s side dashboard, near the steering column. Installation involves disconnecting the battery, removing a few trim panels for access, and carefully swapping the electrical connectors from the old module to the new one. While the programming is done for you, some vehicles may require one or two simple relearn procedures after installation. These are standard for this type of repair and can often be performed by a local mechanic with a capable diagnostic tool.
- Airbag System Sync: If the airbag warning light is on after installation, a “Setup SDM Primary Key in BCM” procedure is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a recalibration of the brake pedal position sensor may be necessary to ensure proper brake light and traction control operation.
There is no core charge for this part. You can keep your old module without the hassle of returning it.
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, the security system, and the instrument cluster.
Do I need to program this module?
No. We handle the programming for you before shipment. You must provide your vehicle’s VIN at checkout so we can load the correct software and vehicle-specific settings for a simple installation.
Where is the BCM located on my truck?
On most 2012-2014 GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard, usually to the left of the steering column.
What is a VIN and why do you need it?
The VIN is your vehicle’s unique 17-digit serial number. It contains information about the manufacturer, model year, and specific options your vehicle was built with. We use it to load the exact software from GM for your vehicle’s configuration.
What if the airbag light comes on after I install it?
This is a normal possibility. The new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A mechanic with a professional scan tool can perform the “Setup SDM Primary Key in BCM” procedure to sync the systems and turn off the light.
Will this BCM fit vehicles other than the Suburban?
Yes. This BCM fits a wide range of GM vehicles from 2012-2014, including the Silverado, Sierra, Tahoe, Yukon, Avalanche, and Escalade. Please check the detailed fitment list on this page to confirm compatibility.
