Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information SAS-U300049

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).
A diagnostic trouble code (DTC) is stored if the control module detects:
- The Steering wheel angle sensor module (SAS) registers incorrect internal reference voltage to the AC/DC converter.
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
- 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
