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.

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been rectified or the fault is no longer active.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.
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).
