Description And Operation: Description
The Body Control Module (BCM), produced by Delphi, is an electronic control unit that manages and controls the following systems:
- Exterior lighting
- Internal lighting
- Electric windows.
- Door locking and unlocking
- Tailgate locking/unlocking
- Wipers and screen washer system
- Fuel level gauge
- Outside temperature
- Immobilizer function
- Brake fluid level
- brake switch
- Vehicle configuration
- Diesel heater on Filter Relay Control
- Hazard warning lights control
- Gateway functions between the high-speed (CAN-C1) and medium-speed (CAN-BH) CANs and LIN
The BCM also constitutes an interconnection unit that ensures a protected supply for many electrical loads via fuses.
The BCM comprises two main boards:
- the power board, which contains the fuses, internal relays and power connections.
- the logic board which contains the microprocessor.
The BCM is positioned under the dashboard lining to the left of the steering wheel behind a plastic cover which is removable for access to the fuses.
