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.

Option 1 Warning Lamp "Coolant Level Sensor"
The "Coolant Level Sensor" parameter determines if the ECM will monitor the input signal of the coolant level sensor. A coolant level sensor that is installed by the Original Equipment Manufacturer (OEM) must be connected to the ECM in order to use this parameter.

GM 530/540 4 Pin No
GMT-560 No 2 Pin Switch
Other 2-Wire Float Sensor No "Engine Oil Pressure Sensor"
An optional engine oil pressure sensor is sometimes installed on applications with an instrument cluster that requires an engine oil pressure gauge. These engines do not require an engine oil pressure sensor for engine protection.Note: The HEUI fuel system will not allow the engine to run if no oil pressure is present. The oil pressure is measured at the injection actuation pressure sensor.If an engine oil pressure sensor is installed in the engine, the "Engine Oil Pressure Sensor" parameter must be set to "Installed". The engine oil pressure signal will be communicated over the ATA data link.

The "Fuel Pressure Sensor" parameter determines if the ECM will monitor the input signal of the fuel pressure sensor. A fuel pressure sensor must be connected to the ECM in order to use this parameter.If a fuel pressure sensor is installed in the engine, the "Fuel Pressure Sensor" parameter must be set to "Installed". The ECM will monitor the low pressure fuel system for a condition of low fuel pressure. The ECM monitors the fuel pressure while the engine is cranked and also while the engine is running.This parameter is used to program the ECM for a fuel pressure sensor that is installed.

Alternatives Default
Not Installed Installed Note: The status of the "Fuel Pressure Sensor" parameter is read at powerup of the ECM. If the parameter is changed, the ECM must be cycled in order for the ECM to recognize the change."Oil Level Switch Installation Status"
Note: This feature is only available when the parameter for "Truck Manufacturer" is programmed to GMT-560. A normally open switch that is installed in the oil pan is used to detect the condition of a low oil level in the engine. The switch circuit is wired to the J2 ECM connector. During the installation of the switch into the oil pan, the switch is oriented so that an engine oil level that is normal will cause the switch to remain closed, and a low engine oil level will allow the switch to open. If the ECM detects an open switch on three sequential starts, low oil level will be indicated.This parameter is used to program the ECM for an oil level sensor that is installed.
