U0010

Diagnostic trouble code (DTC) information SAS-U001000

Condition




The control modules transmit and receive information via a standardized communication network, CAN (Control Area Network). If the Steering Angle Sensor (SAS) registers a serious disturbance on the high speed network (CAN communication blocked) then the trouble code is set.
The Steering Angle Sensor (SAS) is located in the Steering Wheel Module (SWM) from which it is supplied with power. It is however only the Steering Angle Sensor which communicates on the Control Area Network (CAN).

Note! In the event of system communication problems, it is not possible to communicate with the control module. Therefore it will only be possible to read off the fault if it is intermittent.

Substitute value
- The control module switches itself off ("bus-off").

Possible source
- Short-circuit between the control area network (CAN) wiring.
- Open-circuit in the control area network (CAN) wiring
- Internal fault in the control module
- Internal fault in another control module in the same part of the control area network (CAN).

Fault symptom[s]
- Nothing.
