Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information SAS-U300362

Condition
The Steering wheel angle sensor module (SAS) is located in the lever module together with the steering wheel module (SWM) and is supplied with power by it. Only the steering wheel angle sensor module (SAS) communicates on the controller area network (CAN).
The Steering Angle Sensor (SAS) compares the voltage with a known value from the Central Electronic Module (CEM).
A diagnostic trouble code (DTC) is stored if the control module detects:
- Voltage is 2 V lower than the voltage signal from the Central electronic module (CEM) for 10 seconds.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.

Substitute value
- The control module transmits a message to other nodes on the CAN network that its information is incorrect.

Possible source
- Connector resistance or oxidation in the connector to the Steering Wheel Module (SWM).
- Internal fault in the steering wheel angle sensor module (SAS).

Fault symptom[s]
- Information lamp is on
- Anti-spin warning lamp lit
- Traction control not working
- Stability function is not working
- Four-C function not working
