Troubleshooting Test Steps Values Results
1. Perform an ARD Ignition Test and Record the Enhanced Troubleshooting Indicator (ETI)
A. Establish communication between the electronic service tool and the Electronic Control Module (ECM). Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Perform an ARD Ignition Test using the electronic service tool. Refer to System Operation and Testing and Adjusting, "ARD Fuel System - Test".
C. The ETI code is located in the "Active Events" or "Logged Events" screen in the electronic service tool. Record the Enhanced Troubleshooting Indicator (ETI) code.
ETI codes are not available for (2) codes.
ETI Code
Result : There is not an ETI for the diagnostic code.
Proceed to Test Step 2.
Result : The ETI code was recorded.
Proceed to Test Step 2.
2. Check for External Leaks
A. Check for external leaks. Inspect the fuel lines from the pump to the fuel manifold. Check for pinched lines or leaking lines.
External Leaks
Result: A leak or pinched line was not found.
Proceed to Test Step 4.
Result: A leak or pinched line was found.
Repair: Repair all damaged lines or leaking lines. Perform the "ARD Ignition Test" by using the electronic service tool. Refer to System Operation and Testing and Adjusting, "ARD Fuel System - Test". If the "ARD Ignition Test" was successful, return the unit to service.
If the ARD ignition test was not successful, Proceed to Test Step 3.
3. Fuel Supply
A. Visually check the fuel level in the fuel tank. Do not rely on the fuel gauge only.
B. Ensure that the vent in the fuel cap is not filled with debris.
C. Ensure that the fuel supply valve (if equipped) is in the full OPEN position.
D. If the temperature is below 0 °C (32 °F), check for solidified fuel (wax).
E. Check the primary filter/water separator for water in the fuel.
F. Check for fuel supply lines that are restricted.
G. Check that the low-pressure fuel lines are tight and secured properly.
H. Check that the Electric Fuel Lift Pump (EFLP) is operating. If the EFLP is suspect, refer to Troubleshooting, "Fuel Transfer Pump - Test".
I. Replace the in-line fuel filter that is upstream of the primary fuel filter.
J. Replace the primary fuel filter.
K. Check the diesel fuel for contamination. Refer to Systems Operation, Testing, and Adjusting, "Fuel Quality - Test".
