Recommended Actions
Diagnostic Codes
Check for active diagnostic codes on the electronic service tool. Troubleshoot any active codes before continuing with this procedure.ECM Software
Connect the electronic service tool to the diagnostic connector and check for the following conditions:
Check for the correct engine serial number
Check for the correct arrangement number
Check for the correct software
Use the electronic service tool to verify any active diagnostic codes.
If diagnostic codes are present, the ECM must be programmed with the correct information.
If the fault has not been eliminated, proceed to "Air Intake System or Exhaust System". Air Intake System or Exhaust System
Check the air filter restriction indicator, if equipped.
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
Ensure that the valve lash is correct. Reset the valve lash if it is not correct. Refer to Systems Operation, Testing and Adjusting, "Engine Valve Lash - Inspect/Adjust".If the repair does not eliminate the fault, proceed to "Turbocharger (if equipped)".Turbocharger (if equipped)
Note: The turbochargers that are used on 3054E and 3056E engines are nonserviceable items. If any mechanical fault exists then the turbocharger must be replaced.
Ensure that the mounting bolts for the turbocharger are tight.
Check that the turbocharger drain is not blocked or restricted.
Check that the turbocharger housing is free of dirt and debris.
Check the turbocharger for worn bearings.
Check that the turbine blades rotate freely on the turbocharger.
Ensure that the wastegate on the turbocharger is adjusted correctly. Refer to Systems Operation, Testing and Adjusting, "Turbocharger - Inspect".
Make all necessary repairs to the engine.
Ensure that the repairs have eliminated the faults.
If the repairs have not eliminated the fault proceed to "Low Compression (cylinder pressure)". Low Compression (cylinder pressure)
Examples of low compression are shown in the following list:
Loose glow plugs (if equipped)
Mechanical problem
Faulty piston rings
Worn cylinder bores
Worn valves
Faulty cylinder head gasket
Damaged cylinder head
Remove the fuel injection nozzles and perform a compression test. Refer to Systems Operation, Testing and Adjusting, "Compression - Test "data.
Make all necessary repairs to the engine.
Ensure that the repairs have eliminated the faults.
If the repair does not eliminate the fault proceed to "Individual Malfunctioning Cylinder". Individual Malfunctioning Cylinder
With the engine speed at a fast idle, loosen the high pressure fuel line to the fuel injection nozzle of number 1 cylinder. Note if there is any reduction in engine speed. Tighten the high pressure fuel line to the fuel injection nozzle.
Repeat this procedure for each of the remaining fuel injection nozzles. If there is no reduction in the engine speed proceed to "Fuel Injection Nozzles". Fuel Injection Nozzles
Remove the fuel injection nozzles from the cylinder head. Refer to Disassembly and Assembly, "Fuel Injection Nozzles - Remove".
Visually inspect the fuel injection nozzles. If any fuel injection nozzle has a suspected fault, replace the fuel injection nozzle.
Install the fuel injection nozzles into the cylinder head. Refer to Disassembly and Assembly, "Fuel Injection Nozzles - Install".
Ensure that the repairs have eliminated the fault.
