DTC P3119-00: Front/Rear Tire Difference Too Big or All Wheel Information Missing: General Description

The Direct Electro-Hydraulic Actuator (DEHA) AWD system is an automatic variable 4 wheel driving gear. This system distributes an optimum driving torque to front and rear wheels according to a driving condition (a road condition or driving condition). The AWD ECU receives sensor inputs through CAN communication and determines the power distribution for the front/rear wheels. Then it controls a coupling system to transfer driving torque to rear wheels.
