Restore Full Electrical Control to Your GM Truck or SUV
Is your 2012-2014 GMC Sierra, Chevy Silverado, or other GM vehicle acting possessed? Flickering lights, malfunctioning power windows, random security alerts, or a dead battery can often be traced back to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and unpredictable issues. Don’t let electrical gremlins sideline your truck. This direct-replacement BCM is the definitive solution to restore order and functionality.
This isn’t just a part in a box; it’s a complete, ready-to-install solution. We take the hassle and high cost of dealership programming out of the equation. Simply provide your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM software specific to your exact build. This ensures seamless integration and proper function of all your vehicle’s features, right out of the box. This module is a direct replacement for part numbers 22737275, 22846365, and 22846364, guaranteeing a perfect fit and function.
From the Diagnostic Bay
We had a 2013 Silverado 2500 in the shop that was driving its owner crazy. The radio would turn on by itself, the door locks would cycle while driving, and the interior lights would flicker intermittently. The owner had already replaced the battery and checked all the fuses. A full diagnostic scan showed multiple U-codes (communication errors) pointing to a network failure. After isolating the modules, we pinpointed the BCM as the source of the network interference. Installing a VIN-programmed 2012-2014 Sierra BCM was the fix. All the strange electrical issues vanished immediately, and the truck was back to being the reliable workhorse it was meant to be.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security system engaging randomly or preventing the vehicle from starting.
- ✔ Dashboard warning lights illuminating for no apparent reason (e.g., ABS, Airbag, Check Engine).
- ✔ Intermittent no-start conditions or stalling.
- ✔ Problems with the heating and air conditioning controls.
- ✔ Rapid battery drain when the vehicle is off.
Installation and Post-Install Procedures
Physically installing the BCM is straightforward for those with mechanical experience, as it is typically located under the steering column. Once the new module is connected, most functions will be immediately restored. However, depending on your specific vehicle, a couple of additional steps may be required:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and traction control function.
Please note: Specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to send my original BCM in?
No, there is no core charge for this part. You can keep your original module.
Is this BCM truly plug-and-play?
Yes, for the vast majority of vehicles. We program it to your VIN so it’s ready for installation. In some cases, as noted above, minor relearn procedures like an airbag sync or brake pedal position relearn may be needed with a professional scan tool.
Where do I provide my VIN?
You can enter your vehicle’s 17-digit VIN during the checkout process or send it to us with your order number after purchase. We cannot ship the module until we receive your VIN.
What if I install it and still have problems?
While a faulty BCM is a very common cause of widespread electrical issues, it’s important to ensure your vehicle’s wiring, grounds, and battery are in good condition. If you’ve confirmed the rest of the system is healthy, contact our support team for assistance.
Will this fix my check engine light?
It depends on the cause. If the check engine light is on due to communication error codes (U-codes) originating from the BCM, then yes, this will likely resolve it. However, it will not fix codes related to engine or transmission mechanical issues.
