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.

Configuration
Parameters
The
engine
electronic
control
module
(ECM)
has
two
types
of
configuration
parameters.
The
system
configuration
parameters
and
the
customer
specified
parameters.
The
electronic
service
tool
is
required
in
order
to
alter
the
configuration
parameters.
System
Configuration
Parameters
System
configuration
parameters
affect
the
emissions
of
the
engine
or
the
power
of
the
engine.
System
configuration
parameters
are
programmed
at
the
factory.
Normally,
system
configuration
parameters
would
never
require
changing
through
the
life
of
the
engine.
System
configuration
parameters
must
be
reprogrammed
if
an
ECM
is
replaced.
System
configuration
parameters
do
not
require
reprogrammed
if
the
ECM
software
is
changed.
Factory
passwords
are
required
to
change
these
parameters.
