Engine Operation with Intermittent Diagnostic Codes
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 in order to alter
the configuration parameters.

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.
