Is your GM truck or SUV experiencing bizarre electrical problems?
If your 2002-2004 Chevrolet S10, GMC Sonoma, or other compatible GM vehicle is suffering from flickering lights, malfunctioning power windows and locks, a persistent security light, or even a no-start condition, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose issues. Don’t let electrical gremlins keep you off the road. This is the reliable, straightforward solution you need.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights
- ✔ Power windows, door locks, or mirrors not working correctly
- ✔ The security or anti-theft light stays on, preventing the engine from starting
- ✔ Intermittent issues with the radio or instrument cluster gauges
- ✔ A/C and heater controls behaving unpredictably
- ✔ False warning messages on the driver information center

Important Post-Installation Steps
While this module is designed for a straightforward installation, some vehicles may require a simple relearn procedure. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician will need to perform the “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: In some cases, a brake pedal position sensor recalibration may be needed to ensure your brake lights and traction control system function as intended.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation or post-installation process.
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 accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will use this to program the module with the correct software and vehicle-specific options before we ship it to you.
Is this a plug-and-play part?
Yes, for most vehicles. Because we program it to your VIN, it should be a direct installation without needing a trip to the dealer. However, as noted, some vehicles may require minor relearn procedures for the airbag or brake systems.
What if my airbag light is on after installation?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag’s computer (SDM). A repair shop with a capable bi-directional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No. This product has no core charge, so you can keep your original part.
