WARNING: This page is about a different car, the 2020 Hyundai Santa Fe. However, it is still accessible from the selected car via links, so may be relevant.
The 4WD 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.
