Module Controlled Functions - Overview

Body Control Module (BCM) 

The BCM controls various systems by monitoring inputs from switches, sensors and network messaging from other modules. Based on the received inputs, the BCM activates outputs. For example, the BCM monitors the headlamp switch position and based on this input, the BCM will provide power to turn the exterior lamps on. The BCM controls the following (if equipped):

• Battery load shed function
• Battery saver function
