Part name Function
Electronic control coupling
(AWD solenoid)
• Based on a signal from the AWD CM, it operates the electromagnetic clutch and
transmits drive torque to the rear wheels.
Differential oil temperature
sensor
• Informs the AWD CM of the rear differential oil temperature.
AWD CM
• Controls operation of the electronic control coupling (AWD solenoid) based on signals
input from the accelerator pedal opening angle, wheel speed, differential oil temperature
and other sensors.
• Outputs coupling control condition and AWD 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 AWD system.
AWD warning light • Illuminates or flashes to alert driver of a malfunction or control failure in the AWD system.
PCM
• Sends the accelerator pedal opening angle, engine speed signal and other signals, as
CAN signals, to the AWD CM.
TCM • Sends the gear position signal and other signals, as CAN signals, to the AWD CM.
DSC/RSC HU/CM
• Sends the four-wheel speed, DSC/RSC operating condition signal, steering wheel angle
signal and other signals, as CAN signals, to the AWD CM.
• Sends the coupling torque request signal, as a CAN signal, to the AWD CM.
Instrument cluster • Sends the parking brake switch signal, as CAN signal, to the AWD CM.
