Engine Operation with Intermittent Diagnostic Codes
Note: If the customer has selected "DERATE" and
there is a low oil pressure condition, engine power
will be limited 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 lower. Refer to the Troubleshooting for more
information on the relationship between these active
diagnostic codes and engine performance.
Engine Operation with
Intermittent Diagnostic Codes
For Engines with Electronic
Control Modules Only
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 in to the memory of
the Electronic Control Module (ECM).
Usually, an intermittent code will not require the
engine to be stopped. The operator should retrieve
the logged fault codes and reference the appropriate
information 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

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 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 to alter the
configuration parameters.
System Configuration Parameters
System configuration parameters affect the
i07197941
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.
