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.

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.
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.
