Accessing fault information is accomplished through a
double left-click of the fault LED in the historic fault list.
This produces the Historic Fault Information interface
shown in Figure 3-89. From this interface the user can
interpret a diagnostic trouble code (DTC) message, iden-
tify whether or not the fault occurred during the current
key cycle, identify if the fault caused the engine to shut-
down, determine how many key cycles have occurred
since the fault was last active, clear selected or all historic
faults, and view snapshot and flight data. Table 3-16
out-
lines the options displayed in the Historic Fault Informa-
tion screen. Historic faults are not overwritten if the same
fault becomes active, storing data from the original active
fault.
Figure 3-90. is an example of a fault snapshot after View
Fault Snapshot is selected. Data is presented in two col-
umns, base and custom variables. Once retrieved, the
FSS data may be saved to the PC in text format with an
.fss extension. A FSS saved to a PC may be reviewed in
any ASCII based software program.
Figure 3-91. shows the Flight Data Recorder interface after
View Flight Data Recorder is selected. The FDR captures a
ten second (eight seconds prior and two seconds after
generating the fault) strip of data for base and custom
variables. FDR data is presented in an interface similar to
the Plot interface for a quick graphical presentation. From
this interface, the FDR data may be saved to the PC in
text, tab-delimited format with an .fdr file extension. Once
saved to PC, FDR data may be reviewed using any graph-
ical post-processing software capable of handling tab-
delimited formatting.
Fault information may be manually erased using the
“Clear” button functions. Once a “Clear” function has
been selected, the dialog prompt shown in
Figure 3-92.
will be displayed. Choosing YES deletes all fault informa-
tion from the ECM.
