Restore Full Electrical Function to Your GM Truck or SUV
Are you battling a storm of strange electrical issues in your Chevrolet, GMC, or Cadillac? Intermittent power windows, flickering lights, a malfunctioning security system, or random warning messages on your dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to go, it can make your truck feel unreliable and frustrating. This VIN-programmed Body Control Module is the definitive solution to restore your vehicle’s performance and your peace of mind.
Unlike a standard replacement part that requires an expensive trip to the dealership for programming, this module arrives at your door ready for installation. We use your vehicle’s unique VIN to flash the BCM with the latest GM factory software and calibrations specific to your truck’s options. This ensures seamless integration and proper function right out of the box, saving you time, money, and hassle.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior dome lights or exterior lights staying on, flickering, or failing to activate.
- ✔ Erratic or non-functional instrument cluster gauges.
- ✔ The vehicle’s security system acting up, preventing the engine from starting.
- ✔ Horn, wipers, or radio functioning incorrectly.
- ✔ False warning lights appearing on the dashboard, such as for the airbag or traction control system.
- ✔ Communication errors with other vehicle modules when checked with a scan tool.

Installation and Post-Install Procedures
The BCM is typically located under the driver’s side of the dashboard, near the steering column. While installation is straightforward for a DIYer with mechanical experience, some vehicles may require additional calibration steps after the new module is installed. These are simple procedures that can be performed with a professional-grade bidirectional scan tool.
- Airbag System Sync: If the airbag warning light illuminates after installation, the ‘Setup SDM Primary Key in BCM’ procedure must be performed. This syncs the new BCM with the airbag system’s computer (SDM) to ensure safety system integrity.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary. This ensures the brake lights and traction control system receive accurate data from the sensor.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that controls and monitors most of your vehicle’s non-engine related electronic functions. This includes power windows, locks, lights, wipers, the security system, and the instrument cluster, among others.
How can I be sure my BCM is the problem?
While the symptoms listed are common indicators of a faulty 2012-2013 Avalanche BCM, a professional diagnosis with a high-level scan tool is the best way to confirm. A technician can check for communication error codes (U-codes) that point directly to a failing module.
Is this part truly plug-and-play?
Yes, for the most part. Because we program it to your VIN before shipping, it eliminates the need for dealer programming. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which requires a professional scan tool.
Where is my VIN located?
You can find your 17-digit Vehicle Identification Number (VIN) on your driver’s side door jamb sticker, the driver’s side dashboard viewable through the windshield, or on your vehicle’s registration and insurance documents.
What happens if the airbag light is on after installation?
This means the new BCM needs to be synced with the airbag system’s SDM. A technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool to turn off the light and ensure the system is working correctly.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep or dispose of your original module.
