Recommended Actions
Note: If the problem only occurs under certain conditions, test the engine under those conditions. Examples of certain conditions are high engine speed, full load and engine operating temperature. Troubleshooting the symptoms under other conditions can give misleading results.Selected Engine Rating Parameters
Verify that the complaint is not due to a normal operation such as a programmed parameter. Connect an Electronic Service Tool and verify the various parameters. If the following diagnostic code is active, ensure that all the various parameters are programmed.
CID 268-FMI 02, SPN1111-FMI02, Flash Code 56 Check Programmable ParametersVerify that the injector codes are programmed.Starting Aids
Air Inlet Heater
Make sure that the air inlet heater is programmed to the On position. For additional information on the Air Inlet Heater, refer to Troubleshooting, "Air Inlet Heater Circuit - Test".Ether Injection System
Make sure that the ether injection system is programmed to the On position. For additional information on the Ether Injection System, refer to Troubleshooting, "Ether Injection System - Test".Oil Grade Plugs
Make sure that the "Oil Grade" is programmed correctly. For additional information on the Oil Grade Plugs, refer to the Operation and Maintenance Manual, "Engine Oil and Filter - Change".Active Engine Derate
If an active derate occurs, the warning lamp will flash. "Engine Derate" will appear in the first engine status box on any ET status screen. Verify that the set points for "Derate" that are in the Programmable Monitoring System have been programmed to the values that are correct. An SPN-FMI code will appear for an active derate on a J1939 receiving device that will display SPN diagnostic codes.Electrical Connections to the ECM
Check the associated wiring for damage, abrasion, corrosion or incorrect attachment on the following connectors. J1/P1 and J2/P2 ECM connectors, J61/P61 Customer Connector and J403/P403 throttle position sensor connector. Refer to Troubleshooting, "Electrical Connectors-Inspect" for additional information.PTO Enable Switch
Connect an Electronic Service Tool and verify that the PTO Enable Switch is not engaged. Remove J1:56 PTO Enable Switch and cycle power to the ECM. Verify that the problem is still present. If the problem is still present reattach the wires and continue to next step. If the problem is resolved, refer to Troubleshooting, "PTO Enable Switch Circuit - Test".Intermediate Speed Switch
Connect an Electronic Service Tool and verify that the Intermediate Speed Switch is not engaged. Remove J1:45 (Intermediate Speed) and cycle power to the ECM. Verify that the problem is still present. If the problem is still present reattach the wires and continue to next step. If the problem is resolved, refer to Troubleshooting, "Intermediate Speed Switch Circuit - Test".Throttle Position Sensor
Connect an Electronic Service Tool to the service tool connector. Turn the keyswitch to the ON with the engine OFF. Verify that the following diagnostic code has not been logged recently.
CID 091-FMI 08, SPN 091-FMI 08, Flash Code 32 Throttle Position signal abnormalMonitor the throttle position from low idle to full throttle. The duty cycle should be between 5 and 10 percent at low idle. The duty cycle will increase to 90 to 95 percent at full throttle. Refer to Troubleshooting, "Throttle Position Sensor Circuit - Test" for additional information if the change in the throttle position is erratic or if the change in the throttle position is out of range.Circuit for the Electronic Unit Injector
Inspect the J2/P2 ECM connector and the J300/P300 Unit Injector connector for proper connections. Refer to Troubleshooting, " Electrical Connectors - Inspect". Connect an Electronic Service Tool and cut out each cylinder in order to isolate the misfiring cylinder or cylinders. If the results are inconclusive, shut off half of the cylinders and repeat the cylinder cutout test on the active cylinders that are remaining in order to locate those cylinders that are missing. Refer to Troubleshooting, "Injector Solenoid Circuit - Test".Electronic Unit Injector Connector
Check the Unit Injector connectors J300/P300 and associated wiring for damage, abrasion, corrosion or incorrect attachment. Refer to Troubleshooting, "Electrical Connectors-Inspect" for additional information.Low Injection Actuation Pressure
Check the engine oil level. Engine oil is used to activate the high pressure hydraulic pump.
Ensure that the engine oil meets the recommendations of the engine manufacturer. Refer to Operation and Maintenance Manual for further details.
Crank the engine and monitor the Injection Actuation Pressure and the output of the Injection Actuation Pressure Control Valve. The High Pressure Oil system is operating properly if the pressure output is a minimum of 6 MPa (870 psi).
Connect the electronic service tool and check for the following diagnostic code.
CID 164-FMI 11,SPN 164-FMI 11, Flash Code 39 Injector Actuation Press Sensor mechanical failureIf this diagnostic code has been logged recently, refer to Troubleshooting, "Injector Actuation Pressure System-Test".Fuel Supply
Check for a problem with the fuel supply and verify the fuel pressure. Verify that the fuel pressure sensor P209/J209 is installed. Refer to Troubleshooting, "Engine Has A Fuel Supply Problem". For further information, refer to Testing and Adjusting, "Fuel System".Turbocharger outlet pressure sensor (intake manifold air), Rated fuel position and/or FRC fuel position
Monitor "Fuel Position" and "Rated Fuel Limit" on the fourth ET status screen. If "Fuel Position" does not equal "Rated Fuel Limit" then check air inlet manifold pressure.
Verify that there are no active diagnostic codes that are associated with the turbocharger outlet pressure sensor (intake manifold air) or the Atmospheric Pressure Sensor.
Monitor air inlet manifold pressure on the second ET status screen and Atmospheric Pressure for normal operation. Note: Atmospheric Pressure is not a default parameter on an ET status screen. A new parameter screen must be set up in order to monitor the Atmospheric Pressure sensor.Air Inlet and Exhaust System
Check air inlet and exhaust systems for restrictions and leaks. Refer to Testing and Adjusting, "Air Inlet and Exhaust System". Look for an indication of the Warning Lamp or restriction indicators that are tripped if the filters are equipped with these devices. These indicators are associated with plugged filters. Replace the plugged air filters or clean the plugged air filters per the guidelines for operation and maintenance. Repair any leaks that are found in the system.
Note: If the problem only occurs under certain conditions, test the engine under those conditions. Examples of certain conditions are high engine speed, full load and engine operating temperature. Troubleshooting the symptoms under other conditions can give misleading results.Selected Engine Rating Parameters
