NUT 0T0030 - Caterpillar

PID 0100 FMI 01Conditions Which Generate This Code:The Engine Control Module (ECM) detects the following conditions:
The C15 engine oil pressure is below the trip line in Illustration 1 for more than 8 seconds.
The C13 engine oil pressure is below the trip line in Illustration 2 for more than 4 seconds.
Illustration 1 g00997505
C15 low oil pressure
Illustration 2 g03885813
C13 low oil pressure
System Response:The Caterpillar Electronic Technician (ET) will display "LOW OIL PRESSURE" and "DIAG" next to the status for "Engine Oil Pressure". The check engine lamp and the warning lamp will illuminate.Customer passwords are required to clear this diagnostic code.Possible Performance Effect:NoneTroubleshooting: Test Step 1. Check the Engine Oil Level
Check the engine oil level. Expected Result:The engine oil level is OK.Results:
OK - The engine oil level is OK. Proceed to Test Step 2.
Not OK - The engine oil level is low.Repair: Add engine oil to the proper level. Refer to the Operation and Maintenance Manual for more information.STOPTest Step 2. Verify Proper Sensor Installation
Check the installation of the engine oil pressure sensor.
Check the wiring of the engine oil pressure sensor. Refer to the Electrical Schematic for the proper wiring. Ensure that all of the wires and connectors are properly connected. Expected Result:The sensor is properly installed and the wiring is correct.Results:
OK - The sensor is properly installed. Proceed to Test Step 3.
Not OK - The sensor is not installed properly.Repair: Install the engine oil pressure sensor properly. Repair the wiring and/or the connectors to the sensor.Verify that the repair eliminates the problem.STOPTest Step 3. Check for Active Diagnostic Codes
Connect Cat ET to the data link connector.
Check for active diagnostic codes that are related to the barometric pressure sensor (atmospheric pressure) or to the boost pressure sensor. Expected Result:There are no diagnostic codes that are related to the barometric pressure sensor (atmospheric pressure) or to the boost pressure sensor.Results:
OK - There are no diagnostic codes. Proceed to Test Step 4.
Not OK - There is a diagnostic code that is related to the barometric pressure sensor (atmospheric pressure) and/or to the boost pressure sensor.Repair: Troubleshoot the diagnostic code before continuing with this procedure.STOPTest Step 4. Check the Status Screen
Turn the keyswitch to the ON position. The engine should be off.
Monitor the status for "Boost Pressure" and "Engine Oil Pressure" on Cat ET. Expected Result:"Boost Pressure" and "Engine Oil Pressure" are less than 10 kPa (2 psi).Results:
OK - The boost pressure
