Restore Your Vehicle’s Electrical System with a VIN-Programmed BCM
Are you battling frustrating electrical problems in your GM vehicle? Issues like erratic power windows, malfunctioning lights, strange instrument cluster behavior, or a persistent “Service Theft System” message often point to a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and disruptive symptoms. This replacement Body Control Module is the definitive solution to restore full functionality and peace of mind.

Installation and Post-Install Notes
Physical installation is typically a direct swap of the old module. However, depending on your specific vehicle, a couple of simple relearn procedures may be necessary after the new module is connected. These are standard procedures that ensure all related systems are properly synced.
- Airbag System Sync: If the airbag warning light is illuminated 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: Some models may require a brake pedal position sensor relearn to ensure correct brake light and traction control operation.
This Programmed GM Body Control Module is a direct replacement for a vast range of vehicles, including the Chevy Impala, GMC Acadia, Cadillac DTS, Chevy Express, and many more. Please verify your original part number against our extensive cross-reference list and consult the fitment chart to confirm compatibility.
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 a wide variety of electronic functions not related to the engine, such as power windows, locks, lights, wipers, security system, and climate controls.
How does the VIN programming work?
After you place your order, you provide us with your vehicle’s 17-digit VIN. We use this number to load the exact, factory-correct software and settings for your specific vehicle onto the BCM before we ship it to you.
Is this a true plug-and-play part?
For most vehicles, yes. Because it arrives pre-programmed, it eliminates the need for dealer-level programming. In some cases, simple relearn procedures for systems like the airbag or brake sensor may be required, as noted in the description.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What happens if my airbag light is on after installation?
This indicates the new BCM needs to be electronically introduced to the vehicle’s airbag system (SDM). A ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade diagnostic tool to complete the sync and turn off the light.
