DTC P0602-41: ECU Internal Error - SW: General Description

The ATC (Active Transfer Case) AWD system distributes the optimal operational torque to the front and rear wheels according to the driving conditions (road surface, etc.) with the auto variable 4-wheel drive device. The AWD ECU determines the torque distribution condition based on the signals it received from sensors through CAN communication and calculate the torque based on the driving conditions. Then it delivers the torque to the wheels by controlling the 4WD system.
