Electronic Engine Features
The engine 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 monitoring
• Engine speed governing
• System diagnostics
• Aftertreatment Regeneration
• NOx reduction system control on the 404F-22T
engine
For more information on electronic engine features,
refer to the Operation and Maintenance Manual,
“Features and Controls” topic (Operation Section).
Engine Diagnostics
The engine has built-in diagnostics in order to ensure
that the engine systems are functioning correctly. The
operator will be alerted to the condition by a “Stop or
Warning” lamp. Under certain conditions, the engine
horsepower and the vehicle speed may be limited.
The electronic service tool may be used to display the
diagnostic codes.
There are four types of diagnostic codes: active code,
logged code, active event and logged event.
Most of the diagnostic codes are logged and stored in
the ECM. For additional information, refer to the
Operation and Maintenance Manual, “Engine
Diagnostics” topic (Operation Section).
The ECM provides an electronic governor that
controls the injector output in order to maintain the
desired engine rpm.
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 generally predicted by the
average power that is demanded. The average power
that is demanded is based on fuel consumption of the
engine over a period of 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.
