Is Your GM Truck Experiencing Strange Electrical Problems?
If your 2012-2014 Sierra, Silverado, Tahoe, or other GM truck is acting possessed, with flickering lights, malfunctioning power windows, or a dead instrument cluster, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated issues. Don’t let a faulty module keep your truck sidelined. This is your direct-fit, VIN-programmed solution to restore full functionality and peace of mind.
This module arrives at your door ready for installation. We take your vehicle’s VIN and flash the unit with the latest, most stable software directly from GM. This critical step ensures compatibility with your truck’s specific options and systems, eliminating the need for an expensive trip to the dealership for programming. This is the most efficient way to get your vehicle back to 100% operational condition.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Instrument cluster gauges behaving erratically or not working at all.
- ✔ The security system engaging randomly or preventing the vehicle from starting.
- ✔ Radio or infotainment system malfunctions.
- ✔ HVAC (heating and air conditioning) controls not responding correctly.
- ✔ False warning lights appearing on the dashboard.
The Superior Solution: A Pre-Programmed 2012-2014 GM Truck BCM
Replacing a BCM used to be a job reserved for the dealership due to complex programming requirements. Our service changes that. By providing us with your VIN during checkout, you receive a module that is a true plug-and-play component for the core functions of your vehicle. We handle the complex part, so you can handle the installation. This module is a direct replacement for part numbers 22737275, 22846365, and 22846364, ensuring broad compatibility across a wide range of GM trucks and SUVs.
Installation and Post-Install Procedures
The BCM is typically located under the driver’s side of the dashboard, near the steering column. Installation involves disconnecting the battery, removing a few trim panels for access, and carefully swapping the electrical connectors from the old module to the new one.
Important Note on Post-Installation Steps: While our programming handles the majority of the setup, some vehicle systems require a ‘handshake’ with the new BCM. Depending on your specific model and options, you may need a professional scan tool to perform the following procedures:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required to sync the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: To ensure correct brake light operation and stability control function, a brake pedal position sensor relearn might be necessary.
These procedures are straightforward for any qualified technician with a bi-directional scan tool. Always consult a factory service manual for detailed instructions specific to your vehicle.
Frequently Asked Questions
Is this BCM truly plug-and-play?
For most vehicle functions, yes. We program it using your VIN so it communicates correctly with your truck’s main systems. However, as noted, certain safety systems like airbags or brakes may require a simple relearn procedure with a professional scan tool to finalize the installation.
How do I provide my VIN number?
You can add your 17-digit Vehicle Identification Number (VIN) to the notes section during checkout. If you forget, we will contact you via email after your purchase to request it. We cannot ship the module until we have programmed it.
What happens if I don’t perform the post-install relearn procedures?
If your vehicle requires these procedures, you may have persistent warning lights on your dash (like the airbag light) or certain features may not operate as intended. For safety and full functionality, it’s crucial to complete any necessary relearns.
Do I need to send my old BCM back?
No. This product has no core charge. You can keep your original module.
Will this fix my specific electrical problem?
This module will resolve any issue directly caused by a faulty BCM. If you are experiencing any of the common symptoms listed, there is a very high probability this will solve the problem. However, proper vehicle diagnosis is always recommended to rule out wiring or sensor issues.
