Voltage
The ECM automatically warns the operator of low system voltage. The default settings that are programmed at the factory are listed in Table 1.
Table 1
Voltage Monitoring
Parameter Default Setting
Warning setpoint 20 volts
Warning delay 10 seconds
Hysteresis 2 volts
Security level No required password If the voltage is below 20 volts for 10 seconds, a warning will occur. To deactivate the warning, the voltage must rise above 22 volts.The setpoint can be programmed to a value between 20 and 22 volts.Engine Oil Pressure
The ECM automatically performs the following functions for low engine oil pressure:
Warning
ShutdownThe strategy is based on a map of the engine oil pressure versus the engine rpm. For engines that are rated up to 1300 rpm, see Illustration 1. For engines that are rated at 1301 rpm and above, see Illustration 2. The default settings that are programmed at the factory are listed in Table 2.
Table 2

Upper oil pressure limit 175 kPa (25 psi)
Lower oil pressure limit 41 kPa (5.9 psi)
Hysteresis 40 kPa (5.8 psi)
Activation delay 10 seconds

(2) Minimum engine oil pressureIf the engine oil pressure is below the minimum pressure for four seconds, a warning will occur. To deactivate the warning, the engine oil pressure must rise above the hysteresis that is set in the map.If the engine oil pressure is below the minimum pressure for nine seconds, a shutdown will occur.The map cannot be reprogrammed.High Coolant Temperature
The ECM will automatically perform the following functions for high coolant temperature:
Warning
Derating
ShutdownThe default settings that are programmed at the factory are listed in Table 3.
Table 3
High Coolant Temperature
Parameter Default Setting
Warning setpoint 102 °C (216 °F)
Warning delay 5 seconds
Derate setpoint 107 °C (225 °F)
Derate delay 30 seconds
Maximum time of derating 480 seconds
Hysteresis 5 °C (9 °F)
Security level Required password
Maximum derating 25%
Shutdown setpoint 107 °C (225 °F)
Shutdown delay 5 seconds If the coolant temperature is above 102 °C (216 °F) for five seconds, a warning will occur. The coolant temperature must be below 97 °C (207 °F) in order to deactivate the warning.If the coolant temperature is above 107 °C (225 °F) for 30 seconds, a derating will occur. A continuous 25 percent derating is reached in 480 seconds. When the coolant temperature is less than 102 °C (216 °F), the percent of the derating decreases. The percent of the derating decreases until the capability of providing full power is restored. However, if the coolant temperature rises above the setpoint again, the derating will resume.If the coolant temperature is above 107 °C (225 °F) for five seconds, a shutdown will occur.Note: The default setting for the delay of the derating is programmed to the maximum value of 30 seconds. The delay for the shutdown is five seconds. These settings result in a shutdown that occurs before a derating. These settings are programmed because most customers prefer a shutdown for high coolant temperature. The settings can be programmed to different values.The setpoint can be programmed in the range of 90 to 102 °C (194 to 215 °F).Low Coolant Temperature
The ECM will automatically warn the operator of low coolant temperature. The default settings that are programmed at the factory are listed in Table 4.
