Electronic Engine Features
The engine is designed for electronic controls. The
integral on board computer controls the operation of
the engine. Current operating conditions are
monitored. The Electronic Control Module (ECM)
controls the response of the engine to these
conditions and to the demands of the operator. These
conditions and operator demands determine the
precise control of fuel injection by the ECM. The
electronic engine control system provides the
following features:
• Engine speed governor
• Automatic air/fuel ratio control

Extra Features
The following extra features provide increased
engine fuel economy and serviceability:
• Cold starting capability
• Tampering detection
• Diagnostics
Engine Diagnostics
The engine has built-in diagnostics to ensure that all
the components are functioning properly. Under
certain conditions, the engine horsepower and the
vehicle speed may be limited. An electronic service
tool may be used to display the diagnostic code.
There are two categories of codes: diagnostic code
and event code. These two categories of codes may
be in two different states: active and logged.
Most of the diagnostic codes are logged and stored in
the ECM. For additional information, refer to
theOperation and Maintenance Manual, Engine
Diagnostictopic (Operation Section).
Engine Service Life
Engine efficiency and maximum utilization of engine
performance depend on the adherence to proper
operation and maintenance recommendations. In
addition, use recommended fuels, coolants, and
lubricants. Use the Operation and Maintenance
Manual as a guide for required engine maintenance.
Expected engine life is predicted by the average
power that is demanded. The average power that is
demanded is based on fuel consumption of the
engine over a time. Reduced hours of operation at
full throttle and/or operating at reduced throttle
settings result in a lower average power demand.
Reduced hours of operation will increase the length
of operating time before an engine overhaul is
required. For more information, refer to the Operation
and Maintenance Manual, "Overhaul Considerations"
topic.
