Default Conditions for the Monitoring System
Table 3 contains the default conditions that cause an event code to be generated. Table 3 also contains a column that describes the system response when the conditions indicate that an abnormal operating condition exists.
Table 3
Default Conditions and System Response
Event Code Conditions which Generate this Code System Response
E004(3) Engine Overspeed Shutdown The engine rpm has exceeded the trip point for engine overspeed for the delay time. The engine will shut down. The code is logged.
E009(2) High Altitude Derate The ECM detects atmospheric pressure that is less than 92.5 kPa (13.4 psi). The ECM limits the fuel if the engine is operated above the default altitude of 762 m (2500 ft). The ECM will derate the engine in 3 percent increments for every 305 m (1000 ft) increase in elevation up to a maximum derate of 35 percent. The code is logged.
E015(2) High Engine Coolant Temperature Derate The engine coolant temperature is above the trip point temperature for five seconds. If the trip point for the derate is exceeded the derate will reduce power linearly from 0 percent to a maximum of 25 percent over a period of 480 seconds.
The code is logged.
E016(3) High Engine Coolant Temperature Shutdown The engine coolant temperature is above the trip point temperature for five seconds. The engine will shut down.
The code is logged.
E017(1) High Engine Coolant Temperature Warning The engine coolant temperature is above the trip point temperature for five seconds. The code is logged.
E038(1) Low Engine Coolant Temperature Warning The coolant temperature is below the trip point temperature for five seconds. The code is logged.
E039(2) Low Engine Oil Pressure Derate The engine oil pressure is below a map dependent value. The oil pressure is below this value for the delay time. Engine power will be reduced.
The code is logged.
E040(3) Low Engine Oil Pressure Shutdown The engine oil pressure is below a map dependent value. The oil pressure is below this value for the delay time. The engine will shut down.
The code is logged.
E100(1) Low Engine Oil Pressure Warning The engine oil pressure is below a map dependent value. The oil pressure is below this value for the delay time. The code is logged.
E173(1) High Exhaust Temperature Warning The exhaust temperature is above the trip point temperature for five seconds. The code is logged.
E190(1) Engine Overspeed Warning The engine rpm has exceeded the trip point for engine overspeed for the delay time. The code is logged.
