Is Your GM Truck Plagued by Electrical Gremlins?
If your 2012-2014 Silverado, Sierra, or other compatible GM vehicle is experiencing bizarre electrical issues, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and unpredictable problems. From flickering lights and malfunctioning power windows to a vehicle that won’t start, a faulty BCM can bring your daily driver to a standstill. This replacement BCM, part number 22737275, is the definitive solution to restore full functionality and reliability to your truck or SUV.
Symptoms of a Failing 2012-2014 Silverado BCM
A failing BCM doesn’t always trigger a check engine light, making diagnosis tricky. Instead, you’ll notice problems with the systems it controls. If you’re experiencing several of the following issues, it’s a strong indicator that your BCM needs replacement:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Headlights, taillights, or interior lights behaving erratically (staying on, not turning on, or flickering).
- ✔ The security system acting up, causing random alarm triggers or no-start conditions.
- ✔ Wipers operating at the wrong speed or not working at all.
- ✔ Inaccurate or dead gauges on your instrument cluster.
- ✔ Radio or infotainment system malfunctions.
- ✔ Remote keyless entry (RKE) failure.

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 swap is straightforward, some post-installation steps may be required to ensure all systems communicate correctly.
Important: Depending on your vehicle’s specific configuration, one or more of the following procedures may be necessary using a professional-grade diagnostic scan tool:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: To ensure accurate brake light operation and proper function of the traction control/stability control systems, a brake pedal position sensor recalibration might be required.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about performing these procedures.
Frequently Asked Questions
Is this BCM truly plug-and-play?
Yes, for the most part. We program it to your VIN so the vehicle will start and run. However, as with any BCM replacement on these vehicles, you may need a scan tool for post-install procedures like an airbag sync or brake pedal position relearn to clear warning lights and ensure 100% system functionality.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is essential.
Do I need to return my old BCM?
No. This product comes with no core charge. You can keep your original module.
What happens if the airbag light comes on after I install it?
This is a normal possibility. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A technician with a bi-directional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fit my 2013 GMC Sierra 2500?
Yes, this BCM fits a wide range of 2012-2014 GM trucks and SUVs, including the Silverado and Sierra 1500/2500/3500, Tahoe, Suburban, Yukon, and Escalade. It directly replaces part numbers 22737275, 22846365, and 22846364.
