Component Location
General Description

The Steering angle sensor(SAS) is joined to the multi function switch and uses a CAN communication.

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.

DTC Description

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

DTC Detecting Condition

Item

Detecting Condition

Possible cause

DTC Strategy

● CAN massage monitoring

● Faulty SAS

● Faulty HECU

● Open circuit in SAS line

Monitoring Period

● Continuous

Enable Conditions

● Faults are detected if SAS message was not received on time by the CAN controller of HECU.

Fail Safe

● Inhibit the ESP control and allow the ABS/EBD control.

Meanwhile, stop checking the ESP switch failure under the ESP control.
