C1623 CAN Time-out Steering Angle Sensor

General Information

Component Location





General Description

The Steering angle sensor (SAS) is joined to the multi function switch and using a CAN communication.
The SAS is composed of main gear, serve gear1 and serve gear2 to determine the turning direction
If main gear is rotated according to the rotation of steering wheel serve gear1 and serve gear2, which is contact with main gear, will be rotated.
The HECU detects the absolute angle by using magnetic MR effect and the difference gear ratio of each serve gear and then send to the CAN communication line.
The HECU detects the steering wheel's operating speed and operating angle by using absolute angle, and this signal is used as a input signal of anti-roll control.

DTC Description

The HECU checks the CAN communication lines for normal ESC control, and sets this code if an SAS message is not received within predefined time.
