End Your Truck’s Electrical Gremlins for Good
Are you chasing frustrating electrical issues in your GM truck or SUV? Flickering lights, power windows with a mind of their own, a security system that won’t cooperate, or a dashboard lit up with random warnings? These are classic signs of a failing Body Control Module (BCM). Instead of facing a costly trip to the dealership for diagnostics and programming, get the definitive solution delivered to your door. This BCM is professionally programmed to your vehicle’s specific VIN, ensuring it’s ready for installation right out of the box.
Common Symptoms & Your Solution
A faulty BCM can cause a wide range of confusing problems that disrupt your vehicle’s operation and your peace of mind. If you’re experiencing any of the following, this module is the reliable fix you need:
- Intermittent or non-working power windows, door locks, and interior lights.
- Erratic instrument cluster behavior or warning lights (e.g., Service StabiliTrak, security light).
- Remote keyless entry (RKE) failure.
- HVAC controls not responding correctly.
- Communication issues that prevent the vehicle from starting.
This pre-programmed 2012-2014 Sierra 2500 BCM restores full functionality, putting an end to the guesswork and getting your truck back to work.

Expert Insight: The BCM Domino Effect
As a technician with over 20 years of experience, I’ve seen how a failing BCM can create a frustrating domino effect. It’s the central computer for all the ‘body’ electronicsโwindows, locks, lights, security, and more. When it starts to fail, it can send corrupt data to other modules. Suddenly, your radio acts up, or you get a false airbag light, and you start thinking you have multiple, unrelated problems. In reality, it’s often the single BCM at the root of it all. Replacing a faulty 2012-2014 Sierra 2500 BCM doesn’t just fix one problem; it often resolves a whole host of confusing secondary issues, restoring stability to the entire vehicle network.
Important Post-Installation Steps
While this module is programmed for a simple installation, some vehicles may require one or two final calibration steps to sync with other onboard systems. These procedures require a professional-grade bidirectional scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be required on certain models to ensure correct brake light and traction control operation.
Disclaimer: Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to access the exact factory build data for your truck or SUV. We use this information to program the BCM with the correct software and settings for all of your specific options, ensuring a seamless installation and proper function.
Is this part difficult to install?
The physical installation is typically straightforward for someone with basic mechanical skills. The BCM is located under the steering column. The main challenge is not the physical swap but the programming, which we handle for you. Some vehicles may require the post-installation relearn procedures mentioned above, which require a professional scan tool.
Will this fix my specific electrical problem?
This module is the solution for a wide array of issues directly controlled by the BCM, such as power windows, locks, interior lighting, and security systems. While it solves the most common electrical problems, we always recommend a proper diagnosis by a qualified technician to confirm the BCM is the source of your issue before ordering.
What if the airbag light comes on after I install it?
This is a normal possibility. It simply means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module (SDM). A repair shop with a high-end scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to sync the systems and turn off the light.
How do I know if this is the right part for my vehicle?
This module replaces part numbers 22737275, 22846365, and 22846364. You can check the part number on your original BCM to confirm a match. Our fitment list covers many compatible models, but providing your VIN is the best way to guarantee you receive the correct, programmed 2012-2014 Sierra 2500 BCM for your truck.
