ECU FAIL Caution
An ECU FAIL caution is caused by various types
of malfunctions. These include internal ECU
problems, sensor failure or insufficient
performance of air-, fuel- or electrical supply
system (e.g. air filter icing).
Depending on the type of failure, the ECU
failure cautions are either
‘
non latched
’, i.e. the caution message disappears
after the cause of the caution is no longer present or
‘
latched
’, i.e. the caution massage remains until
cleared through maintenance action, and Austro
Engine has to be informed.
Clearing of ‘
non-latched
’ caution:
on the active ECU: clears by itself
on the passive ECU: by switching to that ECU with the
voter switch.
