(1)
An
“
X
”
indicates that the effect on engine performance may occur if the code is active.
(2)
Shut Down the Engine: Operate the engine cautiously. Get immediate service. Severe engine damage may result.
(3)
The operator should go to the nearest location that has a qualified service program.
(4)
Schedule Service: The problem should be investigated when the operator has access to a qualified service program.
(5)
These Flash Codes may affect the system under specific environmental conditions such as engine start-up at cold temperature and cold
weather operation at high altitudes.
(6)
The engine will not start.

Fault
Logging
The
system
provides
the
capability
of
Fault
Logging.
When
the
Electronic
Control
Module
(ECM)
generates
an
active
diagnostic
code,
the
code
will
be
logged
in
the
memory
of
the
ECM.
The
codes
that
have
been
logged
by
the
ECM
can
be
identified
by
the
electronic
service
tool.
The
active
codes
that
have
been
logged
will
be
cleared
when
the
fault
has
been
rectified
or
the
fault
is
no
longer
active.
The
following
logged
faults
can
not
be
cleared
from
the
memory
of
the
ECM
without
using
a
factory
password:
Overspeed,
low
engine
oil
pressure
and
high
engine
coolant
temperature.

Engine
Operation
with
Active
Diagnostic
Codes
If
a
diagnostic
lamp
illuminates
during
normal
engine
operation,
the
system
has
identified
a
situation
that
is
not
within
the
specification.
Use
the
electronic
service
tool
to
check
the
active
diagnostic
codes.
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 and power outputs may
be automatically reduced. Refer to Troubleshooting ,
“Troubleshooting with a Diagnostic Code” for more
information on the relationship between each active
diagnostic code and the possible effect on engine
performance.
i01902995
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).
