SYSTEM / Controller MC: MAIN CONTROLLER Function Outline The signals from engine control dial, sensors and switches are input to MC. Information from ECM, ICF and monitor unit are input to MC by using CAN. MC processes the input signals in the logic circuit and sends the signal equal to target engine speed to ECM (Engine Control Module) by using CAN com- munication in order to control the engine. MC drives the solenoid valve unit and pump control solenoid valve in order to control the pump and valve. MC has the controls as follows.
