Component Location
General Description

Steering Wheel Angle Sensor installed in steering wheel prevents a state of TCB(Tight Corner Braking) by sensing the rotating direction & straight driving of vehicle and is used for EMC duty control. In case of ESP system applied 4WD ECU receives this signal through CAN line, If it is not the case 4WD ECU receives this signal from Steering Wheel Angle Sensor directly.

DTC Description

This code related to Steering Angle Sensor Signal( #2) is set when voltage of signal is above 4.5V or loss of signal is occurred for more than 1sec. In case of ESP system applied this code is set when CAN bus off or ECU internal error occur.

If failure is detected, vehicle is controled with 2WD by intercepting EMC current.
