Troubleshooting Test Steps Values Results
1. Diagnostic Codes
A. Connect the electronic service tool to the diagnostic connector. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the Warranty Report and the Product Status Report 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 needed.
C. Determine if a diagnostic is active or recently logged.
Diagnostic codes
Result: A code other than the codes in Table 1 is present.
Repair: Troubleshoot the code. Refer to the applicable troubleshooting procedure.
Result: One of the codes in Table 1 is present.
Proceed to Test Step 2.
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 Dealer Solutions Network (DSN) if troubleshooting assistance is needed.
Diagnostic Codes
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. Electrical Connectors
A. Check for the correct installation of the ECM J1/P1 and the J2/P2 connectors. Check for correct installation of the connector on the Fuel Rail Pressure Sensor and on the Suction Control Valve for the High-Pressure Fuel Pump.
Connectors
Result: There are suspect connectors.
Repair: Use the electronic service tool to perform the "Wiggle Test".
Repair or replace connectors that are suspect.
Result: There are no suspect connectors.
Proceed to Test Step 4.
4. Fuel Filters
A. Replace the in-line fuel filter that is upstream of the electric fuel lift pump. Refer to the Operation and Maintenance Manual for further information.
B. Replace the primary fuel filter and the secondary fuel filters. Refer to the Operation and Maintenance Manual for further information.
C. If equipped, check the Fuel Tank Breather and replace if necessary.
Fuel filters
Result: The filters have been replaced and the fault is eliminated.
Return the unit to service.
Result: The filters have been replaced and the fault is still present.
Proceed to Test Step 5.
5. Fuel Rail Pressure Sensor
A. Make sure that the engine has been shut down for at least 10 minutes. Use the electronic service tool to check the status of the "Fuel Rail Pressure".
Pressure sensor
Result: The "Fuel Rail Pressure (absolute)" is more than 5,000 kPa (725 psi).
Repair: Test the fuel rail pressure sensor. Refer to Troubleshooting, "Sensor Signal (analog, Active) - Test".
Use the electronic service tool to perform the "Fuel Rail Pressure Test". If the test fails, replace the fuel rail. Refer to Disassembly and Assembly, "Fuel Manifold (Rail) - Remove and Install".
Confirm that the fault has been eliminated.
Result: The "Fuel Rail Pressure (absolute)" is less than 5,000 kPa (725 psi).
For a high fuel rail pressure symptom, proceed to Test Step 6.
For a low fuel rail pressure symptom, proceed to Test Step 11.
6. High Fuel Rail Pressure
A. Use the electronic service tool to perform the "High Pressure Fuel Pump Calibration".
Fuel system
Result: Fuel rail pressure is normal after performing the "High Pressure Fuel Pump Calibration".
Return the unit to service.
Result: Fuel rail pressure is still high after performing the "High Pressure Fuel Pump Calibration".
Repair: Run the engine for a minimum of 30 minutes.
Proceed to Test Step 7.
