Information:
Recommended Actions
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
Diagnostic Codes
Check for active diagnostic codes on the electronic service tool. Troubleshoot any active codes before continuing with this procedure.ECM Parameters
Use the electronic service tool to make sure that the FLS and FTS parameters have been correctly entered.
Use the electronic service tool to ensure that the correct mode was selected.
Use the electronic service tool to verify that the correct engine rating has been provided.
Use the electronic service tool to verify the maximum engine speed limit.
Ensure that the repairs have eliminated the performance problems.
If the repairs have not eliminated the fault, proceed to "Electrical Connectors".Electrical Connectors
Turn the start switch to the ON position.
Use the electronic service tool to verify that the intake manifold pressure is 0 0.5 kPa (00 0.070 psi). Check the 5 Volt sensor supply for the intake manifold pressure. Refer to Troubleshooting, "5 Volt Sensor Supply Circuit - Test".
Use the electronic service tool to verify the throttle position status.
Run the engine until the speed is equal to the maximum no-load speed.
Use the electronic service tool to make sure that the throttle is set to reach the maximum no-load speed.
If the maximum no-load speed cannot be obtained refer to the troubleshooting guide for the machine.
If the fault has not been eliminated, proceed to "Air Intake and Exhaust System".Air Intake and Exhaust System
Ensure that the air filter is clean and serviceable.
Check the air intake and the exhaust system for the following defects:
Blockages
Restrictions
Damage to the air intake and exhaust lines and hoses
Make all necessary repairs to the engine.
If the fault has not been eliminated, proceed to "Valve Lash".Valve Lash
Check the valve lash and reset the valve lash, if necessary. Refer to Systems Operation, Testing and Adjusting, "Engine Valve lash - Inspect and Adjust".
If the repair does not eliminate the fault, proceed to "Turbocharger".Turbocharger
Note: The turbocharger that is installed on this engine is a nonserviceable item. If any mechanical fault exists, except for the wastegate actuator, then the turbocharger must be replaced. The wastegate actuator can be replaced.
Ensure that the mounting bolts for the turbocharger are tight.
Check that the oil drain for the turbocharger is not blocked or restricted.
Check that the compressor housing for the turbocharger is free of dirt and debris.
Check that the turbine housing for the turbocharger is free of dirt and debris.
Check that the turbine blades rotate freely in the turbocharger.
Ensure that the wastegate on the turbocharger is adjusted correctly. Refer to Systems Operation, Testing and Adjusting, "Turbocharger - Inspect". If the wastegate actuator is faulty, replace the wastegate actuator. Refer to Disassembly and Assembly, "Turbocharger - Disassemble" and Disassembly and Assembly, "Turbocharger - Assemble".
If necessary, replace the turbocharger. Refer to Disassembly and Assembly, "Turbocharger - Remove" and Disassembly and Assembly, "Turbocharger - Install".
Check that the repairs have eliminated the faults.
If the fault has not been eliminated, proceed to "Fuel Supply".Fuel Supply
Visually check the fuel tank for fuel. The fuel gauge may be faulty.
Ensure that the fuel supply valve (if equipped) is in the full OPEN position.
If the temperature is below 0 °C (32 °F), check for solidified fuel (wax).
Check the primary filter/water separator for water in the fuel.
Check for fuel supply lines that are restricted.
Check that the low-pressure fuel lines are tight and secured properly.
Check the fuel filters.
Check the diesel fuel for contamination. Refer to Systems Operation, Testing and Adjusting, "Fuel Quality - Test".
Check for air in the fuel system. Refer to Systems Operation, Testing and Adjusting, "Air in Fuel - Test".
Ensure that the fuel system has been primed. Refer to Systems Operation, Testing and Adjusting, "Fuel System - Prime".
Check the fuel pressure. Refer to Systems Operation, Testing and Adjusting, "Air in Fuel - Test".
If the repair does not eliminate the fault, refer to "Low Compression (Cylinder Pressure)".Low Compression (Cylinder Pressure)
Perform a compression test. Refer to Systems Operation, Testing and Adjusting, "Compression - Test ".
If low compression is noted on any cylinders, investigate the cause and rectify any faults.Possible causes of low compression are shown in the following list:
Loose glow plugs
Faulty piston
Faulty piston rings
Worn cylinder bores
Worn valves
Faulty cylinder head gasket
Damaged cylinder head
Perform all necessary repairs.
Ensure that the repairs have eliminated the faults.
If the repair does not eliminate the fault, refer to "Individual Malfunctioning Cylinders".Individual Malfunctioning Cylinders
Use the electronic service tool to perform the "Cylinder Cut-out Test". Note if there is any reduction in engine speed. If a reduction in engine speed is not noted, the isolated cylinder is not operating under normal conditions. If the isolation of a cylinder results in a reduction that is less than normal, the cylinder may be operating below normal performance. Investigate the cause of the fault on any cylinder that is not operating. Investigate the cause of the fault on any cylinder that is operating below normal performance.
If all cylinders have been checked and no faults were detected, proceed to "Electronic Unit Injectors".Electronic Unit Injectors
Use the electronic service tool to perform the "Cylinder Cut-out Test". Note if there is any reduction in engine speed. If a reduction in engine speed is not noted, the isolated electronic unit injector is not operating under normal conditions. If the isolation of a cylinder results in a reduction that is less than normal, the electronic unit injector may be operating below normal performance.
Remove the electronic unit injector from the suspect cylinder. Refer to Disassembly and Assembly, "Electronic Unit Injector - Remove".
Install a new electronic unit injector. Refer to Disassembly and Assembly, "Electronic Unit Injector - Install".
Repeat the test in 1. If the fault is still apparent, remove the replacement electronic unit injector and install the original electronic unit injector. Refer to Disassembly and Assembly, "Electronic Unit Injector - Remove" and Disassembly and Assembly, "Electronic U
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
