Note:
If the customer has selected
“
DERATE
”
and if
there is a low oil pressure condition, the Electronic
Control Module (ECM) will limit the engine power
until the problem is corrected. If the oil pressure is
within the normal range, the engine may be operated
at the rated speed and load. However, maintenance
should be performed as soon as possible.
The active diagnostic code should be investigated.
The cause of the problem should be corrected as
soon as possible. If the cause of the active diagnostic
code is repaired and there is only one active
diagnostic code, the diagnostic lamp will turn off.
Operation of the engine and performance of the
engine can be limited as a result of the active
diagnostic code that is generated. Acceleration rates
may be significantly slower. Refer to the
Troubleshooting Guide for more information on the
relationship between these active diagnostic codes
and engine performance.

Engine
Operation
with
Intermittent
Diagnostic
Codes
If
a
diagnostic
lamp
illuminates
during
normal
engine
operation
and
the
diagnostic
lamp
shuts
off,
an
intermittent
fault
may
have
occurred.
If
a
fault
has
occurred,
the
fault
will
be
logged
into
the
memory
of
the
Electronic
Control
Module
(ECM).
In
most
cases,
it
is
not
necessary
to
stop
the
engine
because
of
an
intermittent
code.
However,
the
operator
should
retrieve
the
logged
fault
codes
and
the
operator
should
reference
the
appropriate
information
in
order
to
identify
the
nature
of
the
event.
The
operator
should
log
any
observation
that
could
have
caused
the
lamp
to
light.
• Low power
• Limits of the engine speed
• Excessive smoke, etc
This information can be useful to help troubleshoot
the situation. The information can also be used for
future reference. For more information on diagnostic
codes, refer to the Troubleshooting Guide for this
engine.
