4.8.3 Event History Log
The GSC400 incorporates an
event history logging system.
When engine failures, events, or
DTCs (Diagnostic Trouble Codes)
occur, an entry is created in the
GSC400 Event History Log. See
Table 24 – – Event Log Entries
below for the possible events that
are stored.
A total of 100 entries can be recorded. Entries may be viewed simply by scrolling
up or down using the “UP” and “DOWN” keys. In addition to the entry reason
information, the associated date and time of the entry will be displayed.
The 100 entries are subdivided into a maximum of 30 events, 40 failures, and 30
DTCs. This prevents one type from flushing the other types from the log.
Simply scroll through the Failure
History Log by pressing the
or keys located on the
GSC400.
The event history log can store
up to 30 events, 30 DTCs, and 40
failures entries. If these are
exceeded, the oldest entry is
replaced with the newest entry. The events, failures, and DTC entries are
displayed together in the log in reverse chronological order (i.e. newest entry
first).
Upgrading the controller firmware to revision 2.00 or above from an earlier
revision will cause the history log to be reset.
