Expert Technician’s Note: The Power of Pre-Programming
Many owners of GM trucks and vans from this era learn the hard way that just swapping a BCM isn’t enough.

This results in a vehicle that still won’t start or has persistent error codes.

Frequently Asked Questions
What does a Body Control Module do?
The Body Control Module, or BCM, acts as the central computer for your vehicle’s non-engine related functions. It manages systems like your interior and exterior lights, power windows, door locks, security system, wipers, and HVAC controls.
Is this BCM difficult to install?
Installation is typically straightforward. The BCM on an Express van is located in the center dash area. The process usually takes less than 15 minutes and involves disconnecting the battery and swapping the electrical connectors. Because our unit comes pre-programmed, no special tools are required for the installation itself.
Will this module fix my airbag light?
This module can resolve BCM-related airbag codes like B1001. However, if the airbag warning light remains on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure may need to be performed with a professional scan tool to sync the new BCM with the airbag system.
