Hyundai Palisade (LX2): Coupling Assembly / Pressure Sensor
Description and operation
The AWD ECU makes a Motor Pump(Actuator) turn round for generating an oil pressure.
And then it presses a multiple disk clutch and transfers the generated torque
into rear wheels. Its torque value varies according to a pressure status.

Description and operation
Description
The AWD ECM controls the Pump Motor Pump (Actuator) to generating an oil pressure.
The pressure engages a multiple disk clutch to transfer torque to the rear wheels.
Description and operation
Description
When the pressure inside the coupling exceeds the set pressure value, this valve
maintains the pressure under the set value by discharging the partial or whole
amount.
