Operation Section
Engine Operation with Intermittent Diagnostic Codes
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.
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
emissions of the engine and/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.
