Is your 2002 Chevy Tahoe or other GM truck suffering from bizarre electrical problems? Flickering lights, malfunctioning power windows and locks, or a persistent security light are all classic signs of a failing Body Control Module (BCM).

This replacement BCM is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
We take the guesswork and high cost out of the repair process.

Installation and Post-Install Procedures
Physically installing the BCM is typically a simple process, as it’s located under the steering column or in the center dash area. Once installed, the vehicle will start and run. However, depending on your vehicle’s specific configuration, a couple of additional steps might be needed:
- Airbag System Sync: If your airbag warning light illuminates after installation, a technician will need to perform a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure your brake lights and traction control system function correctly.
These procedures are straightforward for any qualified mechanic with a modern diagnostic tool.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these functions.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as we program the module specifically for your truck.
Is this part truly plug-and-play?
For the core functions, yes. It comes programmed to your VIN, so your vehicle will start and run. 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.
What if my airbag light is on after installation?
This is a known possibility. It simply means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module. A repair shop can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old BCM?
No. This part has no core charge. You can keep your original module, which saves you the time and expense of a return shipment.
