Operation Order
1.
4WD ECU receives CAN signals from the vehicle's sensors.
2.
4WD ECU calculates the necessary amount of rear-wheel torque and sends the corresponding driving current to the actuator (electronic motor and hydraulic pump).
3.
Hydraulic pressure generated by the actuator moves the piston.
4.
Friction from the piston's movement engages the clutch.
5.
Power is delivered to the rear wheels.
