Diagnostic trouble code (DTC) information SAS-E003
Condition
Steering wheel angle sensor module (SAS) is located inside, and is supplied with power by, the steering wheel module (SWM). Only the steering wheel angle sensor module (SAS) communicates on the controller area network (CAN).
The control module compares its configuration ID with the signal configuration transmitted on the control area network (CAN) by the central electronic module (CEM). If the configuration IDs do not correspond the fault code is stored. The diagnostic trouble code (DTC) is also stored if the communication between the steering wheel angle sensor module (SAS) and the central electronic module (CEM) is interrupted.
NOTE:
In the event of an open-circuit in both the control area network (CAN) cables, it is not possible to communicate with the control module. Therefore it will only be possible to read off the diagnostic trouble code (DTC) if this type of fault is intermittent. When the diagnostic trouble code (DTC) is stored, the control module responds to the diagnostic commands. However, normal control area network (CAN) communication does not work ("Expulsion mode").
Substitute Value
- None.
Possible Source
- Incorrect CAN configuration ID (the control module is not intended for this vehicle, for example it is a used control module with different software/hardware)
- Open-circuit in the control area network (CAN) wiring between the control module and the central electrical module (CEM)
- Incorrect version of software.
Fault symptom[s]
- None.
