"Engine Monitoring Mode"
The engine monitoring system continuously monitors the status of the following engine components:
Coolant level sensor (customer option)
Coolant temperature sensor
Engine oil pressure sensor (customer option)
Fuel level sensor (if equipped)
Intake manifold air temperature sensorThe "Engine Monitoring Mode" determines the level of action that will be taken by the Engine Control Module (ECM) in response to a condition that has the capacity of damaging the engine. As a default setting for the ECM, a check engine lamp will be illuminated when the monitoring system detects an engine condition that is abnormal. The ECM can be programmed to respond to the abnormal condition with the illumination of a warning lamp, with an engine derate, or with an engine shutdown.

Shutdown Warning "Engine Monitoring Lamps"
Note: "Option 1" is not available when the parameter for "Truck Manufacturer" is programmed to GM 530/540 or to GMT-560.The "Engine Monitoring Lamps" parameter allows the customer to configure the engine monitoring software. The parameter is lockable by the customer.If the "Engine Monitoring Lamps" parameter is programmed to "Warning Lamp", then J1/P1-28 is available to the customer for the installation of a check engine lamp circuit. The check engine lamp is used to alert the operator that one of the engine monitoring parameters is not within specifications. The ECM powers the check engine lamp circuit when the engine condition is detected. The ECM will also power this circuit when the engine is derated or when the engine is shutdown due to an abnormal condition.If the "Engine Monitoring Lamps" parameter is programmed to "Option 1", three additional analog outputs are available for engine status lamps. J1/P1-29 is configured as an output for the connection of a low oil pressure lamp and J1/P1-31 is configured for the connection of a high coolant temperature lamp. If a coolant level sensor is used, then J1/P1-30 is also available for the connection of a low coolant level indicator. If the parameter for the coolant level sensor is programmed to "No" then J1/P1-30 is configured as an output for the PTO switch on lamp.When "Engine Monitoring Lamp" is programmed to "Option 1" the engine monitoring lamps will function in the following manner:Note: J1/P1-28 is not affected by the "Option 1" setting.
J1/P1-29 low oil pressure lamp is continuously powered when 100-01 Low oil pressure warning or 100-11 Very low oil pressure is active. The lamp will flash if the engine has been derated due to the condition.
J1/P1-30 low coolant level indicator is continuously powered when 111-01 Low coolant level warning and/or 111-11 Very low coolant level are active. The lamp will flash if the engine has been derated due to the condition.
J1/P1-31 high coolant temperature lamp is continuously powered if 110-00 or 110-11 is active. The lamp will flash if the engine has been derated.
