Fault/Diagnostic Trouble Code Interaction
All fault and diagnostic information is managed through the
Faults page. Interaction includes viewing fault messages,
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 Historic.
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 3-71. shows an example of the fault page
when an active fault has been generated. Notice that the fault
is present in both the active and historic lists and the malfunc-
tion indicator lamp (MIL) has been illuminated. Figure 3-72.
shows an example of the fault page with a historic fault stored
in memory.
