Diagnostic Codes
Check for active diagnostic codes on the electronic service tool. Troubleshoot any active codes before continuing with this procedure.Accessory Equipment
Check all accessory equipment for problems that may create excessive load on the engine. Repair any damaged components or replace any damaged components.If there are no problems with the accessory equipment, refer to "Power Mode Control (If Equipped)".Power Mode Control
Check whether the power mode control is using the data link or the CAN Data Link and then use the appropriate test. Refer to Troubleshooting, "Data Link Circuit - Test" or Troubleshooting, "CAN Data Link Circuit - Test".
Check the engine wiring harness for defects. Refer to Troubleshooting, "Electrical Connectors - Inspect".
If there are no apparent faults, refer to "Fuel Supply".Fuel Supply
Visually check the fuel tank for fuel. The fuel gauge may be faulty.
Ensure that the fuel supply valve (if equipped) is in the full OPEN position.
If the temperature is below 0 °C (32 °F), check for solidified fuel (wax).
Check the primary filter/water separator for water in the fuel.
Check for fuel supply lines that are restricted.
Check that the low-pressure fuel lines are tight and secured properly.
Check the fuel filters.
Check the diesel fuel for contamination. Refer to Systems Operation, Testing and Adjusting, "Fuel Quality - Test".
Check for air in the fuel system. Refer to Systems Operation, Testing and Adjusting, "Air in Fuel - Test".
Ensure that the fuel system has been primed. Refer to Systems Operation, Testing and Adjusting, "Fuel System - Prime".
Check the fuel pressure. Refer to Systems Operation, Testing and Adjusting, "Air in Fuel - Test".
If necessary, repair any faults.
If there are no apparent faults, refer to "Electronic Unit Injectors".Electronic Unit Injectors
With the engine speed at a fast idle, use the electronic service tool to isolate one cylinder at a time. Note if there is any reduction in engine speed. If a reduction in engine speed is not noted, the isolated electronic unit injector is not operating under normal conditions. If the isolation of a cylinder results in a reduction that is less than normal, the electronic unit injector may be operating below normal performance.
Remove the electronic unit injector from the suspect cylinder. Refer to Disassembly and Assembly, "Electronic Unit Injector - Remove".
Install a new electronic unit injector. Refer to Disassembly and Assembly, "Electronic Unit Injector - Install".
Repeat the test in 1. If the fault is still apparent, remove the replacement electronic unit injector and install the original electronic unit injector. Refer to Disassembly and Assembly, "Electronic Unit Injector - Remove" and Disassembly and Assembly, "Electronic Unit Injector - Install".
If the fault is not eliminated, check for active diagnostic fault codes.
