Engine Electronics
For the safety of yourself and of others, and to prevent damage to the engine control module (ECM), understand the
hazards associated with engine electronics.
WARNING
Tampering with the electronic system or the original equipment manufacturer (OEM) wiring installation is dangerous
and could result in injury to people, death, or damage to the equipment.
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 touch the harness connector for the electronic unit injectors while the
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 certain conditions exceed their allowable range, the ECM will initiate immediate action.
The engine monitoring system can initiate the following actions:
•
Warning
•
Derate
•
Shut down
Abnormalities in the following monitored conditions can limit engine speed and/or engine power:
•
Engine coolant temperature
•
Engine oil pressure
•
Engine speed
•
Intake manifold air temperature
•
Diesel exhaust fluid (DEF) system performance
•
Aftertreatment system performance
