Hyundai Palisade: 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...

Replacement
•
When removing with a flat-tip screwdriver or remover, wrap protective
tape around the tools to prevent damage to components...
Adjustment
Description
The friction material inside the coupling will degrade over time. Therefore,
corresponding compensation values must be referenced and entered after replacing
the controller or the coupling.

Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger's seat.
An inflating air bag can forcefully
strike a child or child restraint resulting
in serious or fatal injury.
