Are you battling frustrating electrical problems in your GM truck or van? Issues like flickering lights, malfunctioning power windows, or a security system that has a mind of its own are often caused by a failing Body Control Module (BCM).

Post-Installation Requirements
While this BCM is pre-programmed for your vehicle, some models may require simple relearn procedures after installation to sync with other systems. These are standard procedures for this type of repair.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to satisfy the traction control system.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN allows us to program the BCM with the exact software and settings for your specific model, year, and factory options. This ensures seamless integration and proper function of all electronic features without requiring a trip to the dealership for expensive programming.
Is this part difficult to install?
The physical installation is typically straightforward. On most trucks like the Silverado and Sierra, the BCM is located under the steering column. On Express and Savana vans, it’s usually behind the center dash. The main challenge is the electronic syncing, which is why our pre-programming service is so valuable.
Is this a plug-and-play part?
It is as close to plug-and-play as possible. Because we program it to your VIN, it eliminates the need for initial dealer-level programming. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake systems after installation, which may require a professional scan tool.
What happens if I install a BCM that isn’t programmed?
An unprogrammed BCM will not work correctly. Your vehicle may not start, or critical features like lights, wipers, and power locks will be inoperative. It would then need to be towed to a facility with the proper tools for programming, adding significant cost and inconvenience.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
