DTC C05F5-1C: 4WD/AWD Front/Rear Range Actuator Control Circuit Performance Circuit Voltage Out of Range [12/2019 - ]: Description

The 4WD ECU assembly receives signals from each sensor to control clutch fluid pressure for limiting the center differential operation, which distributes torque according to the driving conditions.
