Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, unresponsive power windows, a security system that acts up, or a battery that mysteriously dies overnight, the culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, controlling everything from the interior lights and power locks to the instrument cluster and keyless entry system. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues in your 2012-2014 Sierra, Silverado, Tahoe, Yukon, or Escalade.
Don’t let a faulty module keep you guessing. This is a direct-replacement Body Control Module, part number 22846364, that arrives at your door fully programmed and ready for installation. We eliminate the most difficult part of the repair: the trip to the dealership for expensive programming. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash the module with the latest, most stable software from GM, ensuring it communicates perfectly with your truck’s specific options and systems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior dome lights or exterior lamps staying on or not turning on at all.
- ✔ The security system light flashing, or the alarm sounding randomly.
- ✔ Key fob failing to lock or unlock the doors.
- ✔ Instrument panel gauges behaving erratically or warning lights appearing for no reason.
- ✔ Unexplained parasitic battery drain leading to a dead battery.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.
The Plug-and-Play Solution for Your 2012-2014 Sierra BCM
Replacing a BCM used to be a job reserved for the dealership, primarily because of the complex programming required to sync the new module to the vehicle. We’ve changed that. Our service provides a seamless repair experience. By programming the module to your VIN before shipping, we ensure that it’s ready to be installed right out of the box. This module is a reliable replacement for part numbers 22737275, 22846365, and 22846364, covering a wide range of GM trucks and SUVs from 2012 to 2014.
Installation and Post-Install Procedures
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 seasoned DIYer or any professional technician, some vehicles may require simple relearn procedures after the new module is installed.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This indicates the new BCM needs to be synced with the SDM (Sensing and Diagnostic Module). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure proper operation of the brake lights and stability control systems. This is also performed with a capable diagnostic tool.
By choosing our pre-programmed module, you are bypassing the most significant hurdle of the repair, saving you time, money, and the hassle of arranging for a tow or a trip to the dealer.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls a wide variety of electronic accessories and body functions. This includes power windows, locks, lights, wipers, keyless entry, and the anti-theft system.
Do I need to get this programmed at the dealership?
No. The main benefit of our service is that we program the BCM to your vehicle’s specific VIN before we ship it to you. This makes the unit ready for installation upon arrival, saving you a trip to the dealer and their associated programming fees.
How do I provide my VIN?
You can enter your 17-digit Vehicle Identification Number (VIN) during the checkout process. Please double-check it for accuracy, as this is critical for correct programming.
What happens if my airbag light comes on after installation?
If the airbag light is on, it means the BCM needs to be synchronized with the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a repair shop with a professional-grade scan tool.
Is a core charge required for this part?
No, there is no core charge for this module. You can keep your original part without needing to send it back to us.
Will this BCM fit models other than the Sierra?
