Diagnostic event and event text
The fault can be identified by means of the diagnostic event. The event text helps you by
providing information on the fault.

Status signal Event number Event text

Example F 042 Sensor corroded
3-digit number
If two or more diagnostic events are pending simultaneously, only the diagnostic message
with the highest priority is shown. Additional pending diagnostic messages are shown in
the Diagnostic list submenu →  85
. The status signal dictates the priority in which
the diagnostic messages are displayed. The following order of priority applies: F, C, S, M. If
two or more diagnostic events with the same status signal are active simultaneously, the
numerical order of the event number dictates the order of priority in which the events are
displayed, e.g.: F042 appears before F044 and before S044.
Past diagnostic messages that are no longer pending are shown in the Event logbook
submenu→  86.

The relevant sensor input for these diagnostic events can be identified with the
Actual diag channel parameter or on the display.
