Troubleshooting Test Steps Values Results
1. Download Information Using the Electronic Service Tool
A. Use the electronic service tool to download the "Product Status Report" (PSR) with histograms before performing any troubleshooting or clearing any diagnostic codes.
Note: The downloaded information will be required by the Dealer Solutions Network (DSN) if troubleshooting assistance is required.
Downloaded information
Result: The information was successfully saved.
Proceed to Test Step 2.
Result: The electronic service tool information was not successfully saved.
Contact the Dealer Solutions Network (DSN) for guidance.
2. Create an Electronic Service Tool Snapshot
A. Select "Snapshot Viewer" on the electronic service tool, using menus: Information -> Snapshot -> Viewer
B. Select the event code and then click "View Graph".
C. Select the following parameter and then click OK.
Engine Speed
D. Select Save to "File to save" a Snapshot File (*.xml). This file will contain all the data in the snapshot and not only the data shown on the graph.
Note: The downloaded information will be required by the DSN if troubleshooting assistance is required.
Snapshot saved
Result: The electronic service tool snapshot was successfully saved.
Proceed to Test Step 3.
Result: The electronic service tool snapshot was not successfully saved.
Contact the DSN for guidance.
3. Boost Leaks
A. Check all clamps and pipes from the outlet of the turbocharger compressor to the inlet manifold for damage/leaks.
Intake air
Result: There is a leak in the intake air system.
Repair: Repair the leak.
Result: No leak is found in the intake air system.
Proceed to Test Step 4.
4. Intake Air Filter
A. Check the air filter restriction indicator, if equipped.
B. Check for ECM codes for inlet air restriction:
107-15: Engine Air Filter 1 Differential Pressure high - least severe (1)
107-16: Engine Air Filter 1 Differential Pressure high - moderate severity (2)
C. Ensure that the air filter is clean and serviceable.
Air filter
Result: The air filter is blocked.
Repair: Replace the air filter element. Refer to the Operation and Maintenance Manual, "Engine Air Cleaner Element - Replace".
Result: A 107-15 or 107-16 code is active
Repair: Refer to Troubleshooting, Inlet Air is Restricted.
Result: The air filter is OK.
Proceed to Test Step 5.
5. Air Intake System
A. Check the air intake system for the following defects:
Blockages
Restrictions
Damage to the air intake ducts and hoses
Loose connections and air leaks
Air intake
Result: The air intake system is blocked, restricted, damaged, or loose.
Repair: Make all necessary repairs to the air intake system.
Result: The air intake system is OK.
Proceed to Test Step 6.
6. Check the Engine Intake Throttle Valve
A. Check the engine intake throttle valve for correct operation. Use the electronic service tool to perform the "Air System Motor Valves Verification Test". If the "Air System Motor Valves Verification Test" indicates a fault, refer to Troubleshooting, "Motorized Valve - Test" for the correct troubleshooting procedure.
Engine intake throttle valve
Result: The engine intake throttle valve has failed.
Repair: Repair or replace the valve.
Refer to Disassembly and Assembly, Throttle Valve (Intake Air) - Remove and Install.
If a new valve is fitted, use the electronic service tool to run the "Engine Throttle Valve Replacement Reset" and then use the electronic service tool to run the "Air System Motor Valves Verification Test".
If the valve is repaired, use the electronic service tool to perform the "Air System Motor Valves Verification Test" and verify that the repair eliminates the fault.
Result: The engine intake throttle valve has not failed.
Proceed to Test Step 7.
7. Inspect Electrical Connections
A. Inspect the electrical connections between the sensor and ECM for loose wires, breaks, or dirt ingress.
Electrical Connections
Result: A connection point has damaged wires or pins.
Repair: Repair the damaged wires or pins.
Result: A wire is loose.
Repair: Resecure wire into correct port.
Result: A connection point has excessive dirt/dust.
Repair: Thoroughly clean the connection point and wire ports in the back of the connector with an air gun or similar. Ensure they are free of dirt and/or dust.
Result: Electrical connections have no loose wires, breaks, or dirt ingress.
Proceed to Test Step 8.
8. Turbocharger
Note: The turbocharger that is installed on the engine is a nonserviceable item. If any mechanical fault exists, then the faulty turbocharger must be replaced.
A. Check that the compressor housing for the turbocharger is free of dirt and debris.
B. Check that the turbine housing for the turbocharger is free of dirt and debris.
C. Check that the turbine blades rotate freely in the turbocharger.
Turbocharger
Result: There is a fault in the turbocharger.
Repair: Replace the turbocharger. Refer to Disassembly and Assembly, "Turbocharger - Remove" and Disassembly and Assembly, "Turbocharger - Install".
Result: The turbocharger is OK.
Proceed to Test Step 9.
9. Check the Aftercooler and Aftercooler Hoses for Leaks
A. Check the Air to Air Aftercooler (ATAAC) for leaks or damage.
B. Check the Air to Air Aftercooler (ATAAC) hoses for leaks or damage.
ATAAC
Result: The ATAAC and hoses are OK.
Proceed to Test Step 9.
Result: The ATAAC and/or hoses are leaking or damaged.
Repair: Repair or replace the damaged ATAAC and/or piping.
If the problem is not resolved, proceed to Test Step 10.
10. Check Joints between Intake Manifold and Head for Leaks
A. Check for signs of leaks between the intake manifold and the cylinder head.
Result: The joints between the intake manifold and the cylinder head are leaking.
Repair: Repair the leaks and verify that the issue is resolved.
If the issue is not resolved, contact the Dealer Solutions Network (DSN).
Result: The joints between the intake manifold and the cylinder head are OK.
