The electronic control system includes Engine Monitoring. The system monitors information about the following items: engine oil pressure, coolant temperature, inlet manifold air temperature and coolant level. All truck engines are shipped from the factory with the following sensors: oil pressure sensor, coolant temperature sensor and inlet manifold air temperature. The vehicle manufacturer is responsible for providing and for installing the coolant level sensor. The coolant level sensor is the only sensor that can be individually selected for Engine Monitoring. The ECM Customer Programmable Parameter enables the coolant level sensor. The default factory setting is "NO". The ECM Customer Programmable Parameters have four levels that are for Engine Monitoring:
Off Mode
Warning Mode (Factory Default)
Derate Mode
Shutdown ModeOff Mode
The ECM will ignore the oil pressure sensor and the coolant level sensor. Coolant Temperature is still used for Cold Mode. Inlet Manifold Air Temperature is used for operation in cold air regardless of the engine monitoring mode.Warning Mode
Warning mode uses the following sensors: Oil Pressure, Coolant Temperature, Inlet Manifold Temperature and Optional Coolant Level Sensor. Table 1 indicates the diagnostic codes that are available. The table also shows the effect on engine performance when the diagnostic code is active. When a diagnostic code is active, the Check Engine Lamp will flash and the Warning Lamp will come on.
