Is Your GM Truck or Van Plagued by Bizarre Electrical Problems?
If you’re dealing with flickering lights, power windows with a mind of their own, a security light that won’t turn off, or a vehicle that refuses to start, a failing Body Control Module (BCM) is the likely culprit. In my 20+ years as a technician, I’ve seen these exact issues on countless Silverado, Sierra, Express, and Savana models. The BCM is the central hub for your vehicle’s body electronics, and when it fails, it creates chaos. Don’t let frustrating electrical gremlins keep you off the road. This is the reliable, straightforward solution you need.
From the Shop Floor: A Real-World Diagnosis
“Just last month, a 2006 Silverado 2500 was towed to my shop. The owner was frustrated because the power locks would cycle on their own, and the dome light would stay on, draining the battery overnight. He had already replaced the battery and checked fuses. After connecting my scan tool, I saw multiple communication loss codes with the BCM. These modules, especially in work trucks, endure constant vibration and heat cycles, which eventually cause internal solder joints to crack. This was a classic BCM failure, a diagnosis I’ve made hundreds of times. Installing a VIN-programmed module like this one resolved all his issues in under an hour.”

Easy Installation Process
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the BCM: On most Silverado and Sierra pickups, it’s under the steering column. On Express and Savana vans, it’s typically located in the center of the dash.
- Disconnect and Remove: Carefully unplug the electrical connectors and remove the mounting bolts holding the old BCM in place.
- Install the New BCM: Mount the new module and securely reconnect all electrical connectors.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Final Procedures: Follow the critical post-installation steps outlined below.
IMPORTANT: Post-Installation Steps Required
After installing your new BCM, two procedures are often necessary to ensure all vehicle systems function correctly. These steps require a professional-grade diagnostic scan tool.
- Airbag System Reset: The ‘Setup SDM Primary Key in BCM’ procedure must be performed. This re-establishes communication between the BCM and the airbag module (SDM), which will turn off the airbag warning light on your dash.
- Brake Pedal Position Sensor Relearn: Some vehicles may require a brake pedal position sensor recalibration. This ensures the brake lights and stability control systems operate correctly.
Note: If you are not comfortable performing these procedures, we strongly recommend seeking assistance from a qualified automotive technician.
