Installation Notes for the 2003-2007 Silverado 3500 Body Control Module
Installation is typically a quick process. The BCM is located under the driver’s side dashboard, near the steering column. After disconnecting the battery, simply unplug the electrical connectors from the old module, remove it, and install the new one in its place. While this 2003-2007 Silverado 3500 Body Control Module is designed for direct installation, some vehicles may require a post-installation procedure:
- Airbag System Sync: If the airbag light remains on after installation, a technician will need to use a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
By replacing your failing BCM, you’re not just fixing a few annoying glitches; you’re restoring the central nervous system of your truck’s electronics. This module is the correct choice for a lasting repair on your Silverado, Sierra, Tahoe, Suburban, and other compatible GM vehicles.
