The Body Control Module (BCM):
- Receives hardwired input from sensors and switches
- Provides logic and output control of certain electrical systems
- Provides load shedding logic and control
- Acts as the central gateway module for the Controller Area Network (CAN) bus
- Supports flashing (reprogramming) of itself
- Is located behind the instrument panel above the left kick panel (1)
Some advantages of the BCM include:
- Elimination of Diagnostic CAN-Diagnostics (CAN-D).
- CAN message optimizations.
- Controls all exterior lighting outputs.
- Intelligent Battery Sensor (IBS) connection on Local Interface Network (LIN) to BCM.
- Interior lighting and dimmable "Mood" lighting.
- Light Rain Sensor (LRS) connection on LIN to BCM.
