Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows, erratic dashboard warnings, or other strange electrical behavior in your 2012-2014 GM vehicle, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, coordinating everything from your interior lights and door locks to the security system. When it fails, it can create a cascade of frustrating and unpredictable problems.
This is a direct-fit replacement Body Control Module, part number 22737275, for a wide range of GM trucks and SUVs. To make your repair as simple as possible, we program the module to your vehicle’s specific VIN before it ships. This critical step ensures compatibility with your vehicle’s existing systems and options, saving you a costly trip to the dealership for programming. Simply provide your VIN at checkout, and we’ll handle the rest.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Dashboard warning lights (like ABS, Airbag, or Security) illuminating for no reason.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The vehicle’s security system acting erratically or preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Communication errors when a diagnostic scan tool is connected.
The Plug-and-Play Solution for Your 2012-2014 Sierra BCM
Don’t let a faulty module keep your truck off the road. Our replacement BCM is the reliable and straightforward solution you need. By programming the unit with the latest GM software updates matched to your VIN, we eliminate the guesswork and additional costs associated with dealer-only repairs. This module is a direct replacement for part numbers 22737275, 22846365, and 22846364, ensuring a perfect match for your original equipment.
Installation is straightforward for a DIY mechanic with basic tools. The BCM is typically located under the driver’s side of the dashboard, near the steering column. After swapping the module, some vehicles may require simple relearn procedures to sync the new module with other systems, such as the airbag or brake pedal position sensor.
Post-Installation Procedures
While we handle the primary programming, your vehicle may require one or more of the following procedures after the new BCM is installed:
- Airbag System Sync: If the airbag warning light is on 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’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to satisfy the traction control system.
Please consult a factory service manual or a qualified technician for detailed instructions specific to your vehicle.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and various other comfort and convenience features.
Why do you need my VIN?
Your vehicle’s 17-digit Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and calibrations for your specific model, year, and factory-installed options. This ensures the module works correctly right out of the box.
Is this BCM difficult to install?
The physical installation is relatively simple for someone with basic mechanical skills, as the BCM is usually located under the steering column. However, some post-installation electronic procedures, like an airbag system sync, may require a professional diagnostic tool.
What happens if I don’t perform the post-installation procedures?
If a required procedure is skipped, you may have persistent warning lights (like the airbag light) or certain features may not function correctly. For example, skipping a brake pedal relearn could affect brake light or traction control operation.
Is there a core charge for my old BCM?
No, there is no core charge. You can keep your original module without any additional fees.
Will this part fit my 2013 Chevy Silverado 2500?
Yes, this BCM fits a wide range of 2012-2014 GM trucks and SUVs, including the Silverado 2500/3500, Sierra 1500/2500/3500, Tahoe, Suburban, Yukon, Escalade, and Avalanche. It is a direct replacement for part numbers 22737275, 22846365, and 22846364.
