"Engine Monitoring Mode"
This parameter determines the level of action that will be taken by the ECM in response to a condition that has the capability to damage the engine. The ECM reads the Caterpillar coolant temperature sensor and the coolant level sensor, if equipped. If the ECM has been programmed to monitor the OEM installed coolant level sensor, the ECM will read that sensor.

| "Shutdown", "Derate" | "Warning" |
"Engine Monitoring Lamps"
This parameter determines the lamp requirements for the Engine Monitoring System. This parameter is lockable. If this parameter is programmed to the Warning Lamp Option, J1/P1:29 is available for the connection of a red Warning Lamp. The Warning Lamp is used to alert the operator that an engine problem is occurring. The Warning Lamp also indicates when the engine is being derated or the lamp will indicate that shutdown will take place.
If this parameter is programmed to Option 1, there will be up to three discrete lamp outputs that are available for use to indicate specific engine problems. "Option 1" configures J1/P1:29 for the connection of a Low Oil Pressure Lamp and "Option 1" also configures J1/P1:31 for the connection of a High Coolant Temperature Lamp. If a coolant level sensor is used, then J1/P1:30 will also be available for the connection of a Low Coolant Level Warning Lamp. If the parameter for the Coolant Level Sensor is programmed to No, then J1/P1:30 can be used to connect a PTO Switch On Lamp.
When "Engine Monitoring Lamp" is programmed to "Option 1" the engine monitoring lamps will function in the following manner:
- J1P1:29 Low Oil Pressure Lamp will be ON if 100-01 or 100-11 are active. The lamp will flash if the engine has been derated.
- J1/P1:30 Low Coolant Level Warning Lamp will be ON when 111-01 and/or 111-11 are active. The lamp will flash if the engine has been derated.
- J1/P1:31 High Coolant Temperature Lamp will be ON if 110-01 or 110-11 are active. The lamp will flash if the engine has been derated.

"Coolant Level Sensor"
This parameter determines if the ECM monitors the input signal of the coolant level sensor. This feature requires the "Engine Monitoring Mode" to be programmed to "Warning", "Derate", or "Shutdown". An OEM installed coolant level sensor must be connected to the ECM in order to use this parameter.
| Alternatives | Default |
| "4-pin" "2-wire Float" |
"None" |
"Oil Pressure Sensor"
An optional oil pressure sensor is sometimes installed on applications with an instrument cluster that requires an engine oil pressure gauge. The engine does not require an engine oil pressure indicator for engine protection. The HEUI fuel system will not allow the engine to run if no engine oil pressure is present.
If the oil pressure sensor is installed in the engine, the "Oil Pressure Sensor" parameter must be set to "Installed". The engine oil pressure signal will be communicated over the ATA Data link.
| Alternative | Default |
| "Installed" | "Not Installed" |
