Description of the Indication
When the keyswitch is switched on,
the lamps come on for a period of
2 seconds and the lamps will then
go off.
With the engine in operation, there
are no active warnings, diagnostic
codes or event codes.
If the warning lamp comes on
during engine operation, and the
diagnostic lamp is flashing , the
lamps indicate that one or more of
the warning values for the engine
protection strategy have been
exceeded and that there is an
active event code. However, the
value has not been exceeded to a
level that will cause a derate or a
shutdown.
If both the warning lamp and the
derate lamp come on during engine
operation, and the diagnostic lamp
is flashing, the lamps indicate that
one or more of the values for the
engine protection strategy have
been exceeded beyond the level
that will cause an engine derate.
If both the warning lamp and
the shutdown lamp come on
during engine operation, and the
diagnostic lamp is flashing, the
lamps indicate that one or more
of the shutdown values for the
engine protection strategy has
been exceeded and there is an
active event code.
When the diagnostic lamp flashes
during operation of the engine,
the lamp indicates that an active
diagnostic code (an electrical fault)
is present. However, the diagnostic
code is not serious enough to
cause a derate or a shutdown.
