In case of EPS equipped vehicle, the Steering angle sensor(SAS) is installed in MDPS assembly.
The SAS is used to determine turning direction and speed of the steering wheel.
The HECU uses the signals from the SAS when performing ESP-related calculations.
The steering angle sensor in the ESP system is an absolute angle sensor type. For this reason, the steering angle sensor needs the zero setting(Calibration) by the GDS. If the calibration of this sensor is undone, this DTC is set.
