Diagnostic Trouble Code (DTC) Information SAS-U300081

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 wheel angle sensor module (SAS) contains 2 x processors that operate together. he processors communicate with each other and continually check the communication that is transmitted between them.

A diagnostic trouble code (DTC) is stored if the control module detects:

• Communication fault.

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).
