Warning LightIlluminates to warn the driver of a malfunction in the 4WD system.
Speed Sensor (4)Detects the wheel speed of each 4 wheel.
Steering Angle SensorDetects the direction and angle of the steering wheel.
Yaw Rate & Deceleration SensorDetects the vehicle’s longitudinal and lateral acceleration.
Crankshaft Position SensorDetects the engine speed and outputs it to the ECM.
Accelerator Pedal Position SensorDetects the accelerator pedal position and outputs it to the ECM.
Throttle Position SensorDetects the throttle valve position and outputs it to the ECM.
Park / Neutral Position SwitchDetects the neutral position of the transaxle and outputs it to the
ECM.
Stop Light SwitchDetects the brake pedal depressing signal.
Parking Brake SwitchDetects when the parking brake lever is pulled up.
Four-wheel Drive Lock SwitchSwitches between the AUTO and LOCK modes.
4WD ECU
Controls the amperage that is applied to the electromagnetic
solenoid of the electric control coupling based on the signals
provided by the sensors in order to optimally distribute drive torque
in accordance with driving conditions.
ECMOutputs signals such as the shift position signal, throttle position
signal, and crankshaft position signal to the 4WD ECU.
Skid Control ECUOutputs signals such as the vehicle speed signal and deceleration
signal to the 4WD ECU.
Electric Control CouplingDistributes drive torque in accordance with the amperage applied
by the 4WD ECU.
