Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect the electronic service tool to Cat® Electronic Technician (ET). 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.
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. Inspect the Fuel System
A. Inspect the fuel system and return lines. Refer to Systems Operation/Testing and Adjusting, "Fuel System - Inspect" for inspection of the high-pressure fuel lines and the fuel rail.
B. Make sure that the fuel return line is not blocked or kinked.
Fuel System Problems
Result: Problems were found with the fuel system.
Repair: Repair the components or replace the components that are damaged. Verify that the problem is resolved.
Result: Problems were not found with the fuel system.
Proceed to Test Step 3.
3. Check the Status of the Fuel Rail Pressure Sensor
A. Make sure that the engine has been shut down for at least 10 minutes. Use Cat ET to check the status of the "Fuel Rail Pressure".
Fuel Rail Pressure Sensor
Result: The "Fuel Rail Pressure (absolute)" is more than 2000 kPa (290 psi).
Repair: Replace the fuel rail pressure sensor.
