Custom Fault Variable Interface - Kubota WG1605-E3 Diagnostic Manual

WG1605-G-E3,WG1605-L-E3,WG1605-GL-E3, DM
Once an active fault has occurred two sets of data
are recorded, fault snapshot and flight data recorder.
The fault snapshot (FSS) is a sample of data taken at the
instance the fault triggered. Variables included in the
FSS are defined in the Snapshot Base and Snapshot
Custom Definition fields found on the Faults Page. A
FSS is saved with each of the first eight (8) faults for the
first time the fault becomes active. Conversely, the flight
data recorder (FDR) is a ten-second stream of data that
includes eight-seconds prior and two-seconds after
triggering the fault. An FDR is saved for each of the first
two (2) faults for the first time the fault becomes active.
Variables included in the FDR are defined in the Flight
Data Base and Flight Data Custom Definition fields
found on the Faults Page.

Custom Fault Variable Interface

The memory location of the FDR is RAM, therefore
this data is only available if the ECM has not lost battery
power. In addition, if there is a "Dirty Flash Page" in the
ECM, the FDR data will not be available. The memory
location of the FSS data is EEPROM and is retained
when the ECM loses battery power.
Both sets of data are accessed from the Historic
Fault Information interface and can be saved to the PC
upon retrieval. Base variables for FSS and FDR are
generally defined by the Kubota to include variables
most often referenced during fault diagnosis. The base
definitions are not fault dependent. Additional variables
may be selected for capture during a fault occurrence
through a single, left-click of the custom table and
selecting the desired variables from a list. An example of
custom fault variable definitions is shown in Figure 3.
