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been rectified or the fault is no longer active.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 electronic service
tools to check the active diagnostic codes.
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.
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).
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.
