Diagnostic Codes
Check for active diagnostic codes on the electronic
service tool. Troubleshoot any active codes before
continuing with this procedure.
ECM Software
1. 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
2. Use the electronic service tool to verify any active
diagnostic codes.
3. If diagnostic codes are present, the Electronic
Control Module (ECM) must be programmed with
the correct information.
4. If the repairs have not eliminated the fault proceed
to "Air Intake System or Exhaust System".
Air Intake System or Exhaust System
1. Check the air filter restriction indicator, if equipped.
2. Ensure that the air filter is clean and serviceable.
3. Check the air intake and the exhaust system for
the following defects:
•
Blockages
•
Restrictions
•
Damage to the air intake and exhaust lines and
hoses
4. Make all necessary repairs to the engine.
5. 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".

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.
1. Ensure that the mounting bolts for the turbocharger
are tight.
2. Check that the oil drain for the turbocharger is not
blocked or restricted.
3. Check that the compressor housing for the
turbocharger is free of dirt, debris and damage.
4. Check that the turbine housing for the turbocharger
is free of dirt, debris and damage.
5. Check that the turbine blades rotate freely in the
turbocharger.
6. Ensure that the wastegate on the turbocharger is
adjusted correctly. Refer to Systems Operation,
Testing and Adjusting, "Wastegate - Inspect".
If the wastegate actuator is faulty, replace the
turbocharger. Refer to Disassembly and Assembly,
"Turbocharger - Remove" and Disassembly and
Assembly, "Turbocharger - Install".
7. If necessary, replace the turbocharger. Refer
to Disassembly and Assembly, "Turbocharger
- Remove" and Disassembly and Assembly,
"Turbocharger - Install".
8. Check that the repairs have eliminated the fault.
9. If the repairs have not eliminated the fault proceed
to "Low Compression (Cylinder Pressure)".
Low Compression (Cylinder Pressure)
1. Perform a compression test. Refer to Systems
Operation, Testing and Adjusting, "Compression
- Test ".
2. 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 bores
•
Worn valves
•
Faulty cylinder head gasket
