Electronic control coupling (4WD solenoid) | • Based on a signal from the 4WD CM, it operates the electromagnetic clutch and transmits drive torque to the rear wheels.
Differential oil temperature sensor | • Informs the 4WD CM of the rear differential oil temperature.
4WD CM | • Controls operation of the electronic control coupling (4WD solenoid) based on signals input from the accelerator pedal opening angle, wheel speed, differential oil temperature and other sensors. • Outputs coupling control condition and 4WD warning control information as a CAN signal. • Controls the on-board diagnostic system and the fail-safe system if there is a malfunction in the 4WD system.
4WD warning light | • Illuminates or flashes to alert driver of a malfunction or control failure in the 4WD system.
PCM | • Sends the accelerator pedal opening angle, engine speed signal and gear position signal and other signals, as CAN signals, to the 4WD CM.
DSC HU/CM | • Sends the four-wheel speed, DSC operating condition signal, steering wheel angle signal and other signals, as CAN signals, to the 4WD CM. • Sends the coupling torque request signal, as a CAN signal, to the 4WD CM.
