Table 1
Troubleshooting Test Steps Values Results
1. Check for Active or Logged Diagnostic Codes
A. Check for logged diagnostic codes or active diagnostic codes. If a diagnostic code is logged or active refer to Troubleshooting, Diagnostic Trouble Codes, for more information.
Codes
Result: There are logged or active diagnostic codes.
Troubleshoot any logged or active diagnostic codes before continuing with this procedure. Refer to Troubleshooting, Diagnostic Trouble Codes for more information.
Result: There are no logged or active diagnostic codes.
Proceed to Test Step 2.
2. Check the Engine Oil Level and Obtain an Oil Sample
A. Check oil level and obtain an oil sample. If the oil level is high, then take an oil sample to check for fuel dilution. Refer to Troubleshooting, Oil Contains Fuel if fuel is present.
Oil
Result: The engine oil sample shows moitor or action required, then skip to Step 5.
Make necessary repairs.
Result: The engine oil sample and oil level are OK.
Proceed to Test Step 3.
Result: The engine oil level is not at the correct level.
Determine root cause of why the oil level was high or low.
3. Excessive Idle or High Load
A. Use Cat Electronic Technician (ET) to check the Current Totals for excessive idle time and/or for a high load factor. These factors would be indicative of poor operating habits.
Idle time or load
Result:The idle times or load was excessive.
Reduce idle times or load.
Result:The idle times or load was not excessive.
Proceed to Test Step 4.
4. Check the Fuel System
Refer to Systems Operation/Testing and Adjusting, Fuel System, for additional information.
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. Inspect the fuel system for external leaks.
D. Check that there is no air in the clear primary fuel filter. Refer to Systems Operation/Testing and Adjusting, Low Fuel Pressure System- Test.
E. Change the primary fuel filter and the in-line filter for the fuel transfer pump.
F. Check fuel quality. Refer to Systems Operation/Testing and Adjusting, Fuel Quality - Test, for the proper procedure. Check the fuel tank for debris or foreign objects which may block the fuel supply.
G. Check for the proper operation of the fuel transfer pump. Replace the pre-filter if excessive contamination or if the maintenance interval is exceeded. Refer to Systems Operation/Testing and Adjusting, Low Fuel Pressure System-Test, for test information.
Fuel system
Result:The fuel system is OK.
Proceed to Test Step 5.
Result:The fuel system is not OK.
Make necessary repairs.
5. Fuel Injectors
A. If service has been performed on the engine fuel system recently, verify that the injector trim codes in the Engine ECM match the injector for each cylinder. If injectors were moved between cylinders or if an injector was replaced and the injector trim codes were not updated in the Engine ECM, this can cause an engine miss.
B. Access the "Cylinder Cutout Test"
