1.9.2 Engine Electronics
WARNING
Tampering with electronic system installation or original equipment manufacturer (OEM) wiring
installation can be dangerous and could result in personal injury or death and/or engine damage.
WARNING
Electrical Shock Hazard. The electronic unit injectors use DC voltage. The engine control module (ECM)
sends this voltage to the electronic unit injectors. Do NOT come in contact with the harness connector for
the electronic unit injectors while engine is operating. Failure to follow this instruction could result in
personal injury or death.
This engine has a comprehensive, programmable engine monitoring system. The ECM has the ability to monitor
engine operating conditions. If conditions exceed the allowable range, the ECM will initiate immediate action.
The following actions are available for engine monitoring control:
• Warning
• Derate
• Shut down
The following monitored engine operating conditions have the ability to limit engine speed and/or engine power:
• Engine coolant temperature
• Engine oil pressure
• Engine speed
• Intake manifold air temperature
The engine monitoring package can vary for different engine models and different engine applications. However,
monitoring system and engine monitoring control will be similar for all engines. Together, two controls provide
engine monitoring function for specific engine application.
