Diagnostic trouble code (DTC) information SWM-E003
Condition
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 control module and the central electronic module (CEM) is interrupted.
NOTE:
In the event of 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 command, however normal control area network (CAN) communication does not work. ("Expulsion mode")
Substitute Value
- None.
Possible Source
- Faulty Control area network (CAN) configuration ID. (The node is not intended for this car, for example 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).
Fault symptom[s]
- Windshield wipers only operate at lowest speed
- Front windshield washing does not work
- Rear windshield washing does not work
- The turn signal lamp switch does not work
- Cruise control does not work at all
- The turn signal lamps do not work.
