Module, Body Control (BCM): Description
The Body Control Module (BCM) (1) is mounted in the dashboard, left of the steering wheel, behind a removable aesthetic cover that allows the access to fuses mounted on the component.
The BCM:
- Is the configuration master for the vehicle. As the configuration master, the BCM broadcasts configuration data over the bus whenever the ignition is in the RUN state.
- Receives hardwired input from sensors and switches.
- Provides logic and output control of certain electrical systems.
- Provides load shedding logic and control.
- Is the central gateway module for the Controller Area Network (CAN) and Local Interface Network (LIN) bus networks.
- Supports flashing (reprogramming)
Some functional advantages of the BCM include:
- CAN message optimizations
- Controls all exterior lighting outputs
- Intelligent Battery Sensor (IBS) connection on LIN to the BCM
- Interior Lighting and Dimmable "Mood" Lighting
