Engine Monitoring
The electronic control system includes Engine Monitoring. The system monitors 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 OEM is responsible for providing and 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 enabled. The ECM Customer Programmable Parameters have four modes 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 Coolant Level. 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.

105-00 High Air Inlet Temperature Warning SOLID NONE
105-11 Very High Air Inlet Temperature Warning SOLID NONE
110-00 High Coolant Temperature Warning SOLID NONE
110-11 Very High Coolant Temperature SOLID NONE
111-01 Low Coolant Level Warning SOLID NONE
111-11 Very Low Coolant Level SOLID NONE Derate Mode and Shutdown Mode
Derate mode and Shutdown mode allows the ECM to alter engine performance. Derate mode and Shutdown mode helps the engine avoid damage. The engine should return to normal conditions. When the engine is derated, the Check Engine Lamp and the Warning Lamp will flash. Refer to Table 2. In the Derate column, MPH indicates that the vehicle speed is derated. The maximum derate is 45 mph. HP indicates that the engine horsepower is limited. The maximum derate is 160 hp. RPM indicates that the engine speed is limited. The maximum derate is 1350 rpm. For the operating conditions that cause these codes, refer to the appropriate section for the sensor.

HP Time to Shutdown
Table 3 indicates the active diagnostic codes that are capable of shutting down the engine when the ECM is programmed to Shutdown. The "Time To Shutdown" column indicates the length of time until engine shutdown will occur. The engine must have been running for at least thirty seconds. "Start/Restart Time" is the amount of operation time before shutdown after the engine monitoring has just caused a shutdown. "NO" in the column indicates that the code will not cause engine shutdown.
