SYSTEM / Controller CAN: CONTROLLER AREA NETWORK (NETWORK PROVIDED FOR MACHINE) MC, ECM, ICF and the monitor unit are connected by using CAN bus line and communicate the signal and data each other. CAN bus line consists of two harnesses, CAN High and CAN Low. Each controller judges the CAN bus line level due to potential difference between CAN High and CAN Low. Each Controller arranges the CAN bus line level and sends the signal and data to other controllers.
