Installation and Post-Install Procedures
Replacing the Silverado 2500 Body Control Module is straightforward. It is located under the driver’s side of the dashboard, near the steering column. The physical swap typically takes just a few minutes. However, be aware of two potential post-installation steps:
- Airbag System Sync: If the airbag warning light remains on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure using a professional-grade scan tool. 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 the brake lights and traction control system function correctly.
Always consult a factory service manual or a qualified technician if you are unsure about these procedures.
Frequently Asked Questions
Will this BCM need to be programmed by a dealer?

What does a Body Control Module do on a Silverado 2500?
