Diagnostic Codes
Use one of the following methods to check for active diagnostic codes:
The electronic service tool
The display on the control panelElectronic Service Tool
Connect the electronic service tool to the diagnostic connector.
Check for active diagnostic codes on the electronic service tool.
Investigate any active codes before continuing with this procedure. Refer to Troubleshooting, "Troubleshooting with a Diagnostic Code".Display on the Control Panel
Check the display on the control panel for active diagnostic codes.
Troubleshoot any active codes before continuing with this procedure. Refer to Troubleshooting, "Troubleshooting with a Diagnostic Code".Use the electronic service tool to check the setup of the throttle.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 repairs have not eliminated the fault, proceed to "Air Intake System or Exhaust System".Air Intake System or 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
Ensure that the valve lash is correct. Refer to Systems Operation, Testing and Adjusting, "Engine Valve Lash - Inspect".If the fault is not eliminated, proceed to "Turbocharger".Turbocharger
Note: The turbocharger that is installed on this engine is a nonserviceable item. If any mechanical fault exists, then the turbocharger must be replaced.
Ensure that the mounting bolts for the turbocharger are tight.
Check that the oil feed for the turbocharger is not blocked or restricted.
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, debris, and damage.
Check that the turbine housing for the turbocharger is free of dirt, debris, damage, and oil deposits.
Check that the turbine wheel rotates freely in the turbocharger. Make sure that the compressor wheel rotates with the turbine wheel.
Ensure that the wastegate on the turbocharger is operating correctly. Refer to Systems Operation, Testing and Adjusting, "Turbocharger - Inspect". If the wastegate actuator is faulty, replace the turbocharger. Refer to Disassembly and Assembly, "Turbocharger - Remove" and Disassembly and Assembly, "Turbocharger - Install".
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 repairs have not eliminated the fault, proceed 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 the cause.Possible causes of low compression are shown in the following list:
Loose glow plugs
Faulty piston
Faulty piston rings
Worn cylinder
