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 3-74.
From this interface the user can interpret a diagnostic trouble
code (DTC) message, identify whether or not the fault
occurred during the current key cycle, identify if the fault
caused the engine to shutdown, 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 3-12
outlines the options displayed in the Historic
Fault Information screen. Historic faults are not overwritten if
the same fault becomes active, storing data from the original
active fault.
Figure 3-75. is an example of a fault snapshot after View Fault
Snapshot is selected. Data is presented in two columns, 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 3-76. 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 graphical post-processing software capa-
ble 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 3-77. will be displayed.
Choosing YES deletes all fault information from the ECM.
