General Information

Component Location





General Description

The Steering angle sensor (SAS) is installed in MDPS (Motor Driven Power Steering) and it sends messages to HECU through CAN communication line.
The SAS is used to determine turning direction and speed of the steering wheel.
The HECU uses the signals from the SAS when performing ESC-related calculations.

DTC Description

The SAS used for ESC control needs 0 set because the SAS measures a absolute angle.
0 set is done by using the scantool device. If abnormal 0 set is detected or no information in SAS is detected, a failure is reconized.
