BCU to harness connectors (Body control unit)

BCU outputs The BCU processes the input signals it receives and uses the information to determine the control outputs that need to be established for any given set of conditions. The BCU provides controlled outputs for the following systems: l Interior courtesy lamps. l Fuel flap release actuator. l Anti-theft status LED. l Engine Control Module. l Door lock actuators. l Direction indicators and hazard warning lamps. l Headlamps. l Alarm sounder. l Vehicle horns. l Battery backed sounder. l Starter relay. l Passive re-mobilisation exciter coil.

Simultaneous switching of outputs in different units is limited by the bus transfer time, but the skew is no longer than 100 ms for either the BCU or the IDM. When the processor is reset, all outputs are switched off until the inputs have been read for the first time to check current condition.
