Fault/Diagnostic Trouble Code Interaction
All fault and diagnostic information is managed through
the Faults page. Interaction includes viewing fault mes-
sages, downloading fault data (fault snapshot and flight
data recorder), erasing faults from memory, and defining
variables for fault data logging.
Faults are separated into two categories, Active and His-
toric. Active faults are active in real-time and historic faults
have been generated at some instance in time that may or
may not be active in real-time. Once a fault has become
active, it is immediately logged as historic and a snapshot
and flight data log is saved. Figure 3-86. shows an exam-
ple of the fault page when an active fault has been gener-
ated. Notice that the fault is present in both the active and
historic lists and the malfunction indicator lamp (MIL) has
been illuminated. Figure 3-87. shows an example of the
fault page with a historic fault stored in memory.
