Troubleshooting Test Steps Values Results
1. Determine the Code
A. Connect Cat® Electronic Technician (ET) to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
Codes
Result: An E198 or 5580 code is present.
Proceed to Test Step 2.
Result: An associated code is present.
Repair: Troubleshoot the associated code. Refer to the proper troubleshooting procedure.
2. Check the Fuel Level in the Tank
A. Visually inspect the fuel level in the fuel tank. Ensure that the fuel tank contains enough fuel to operate the engine.
B. Ensure that the fuel supply valve (if equipped) is in the full OPEN position.
Fuel Level
Result: The fuel level is OK.
Proceed to Test Step 3.
Result: The fuel level is not OK.
Repair: Fill the tank. Verify that the problem has been resolved.
If the problem is not resolved, proceed to Test Step 3.
3. Inspect the Fuel System for Leaks
A. Perform a visual inspection of the fuel system. Verify that there are no fuel leaks. Inspect the fuel lines from the fuel transfer pump to the secondary fuel filter base for restrictions. Refer to Systems Operation/Testing and Adjusting, "Fuel System - Inspect" for additional information.
Leaks in the Fuel System
Result: No leaks were found.
Proceed to Test Step 4.
Result: Leaks were found in the fuel system.
Repair: Repair the leaks. Verify that the problem is resolved.
If the problem is not resolved, proceed to Test Step 4.
4. Replace the Fuel Filters
A. Replace the primary filter, the secondary filter, and the tertiary fuel filters.
B. Reset all active codes by cycling the keyswitch to the Off position for 2 minutes.
C. Prime the fuel system. Make sure the fuel system is primed.
Fuel Filters
Result: The problem has been resolved.
Return the engine to service.
Result: The problem has not been resolved.
Proceed to Test Step 5.
5. Check for Air in the Fuel System
A. Check for air in the fuel. Refer to Systems Operation/Testing and Adjusting, "Air in Fuel - Test" for the proper procedure
Air in the System
Result: Air is in the system.
Repair: Refer to Systems Operation/Testing and Adjusting, "Air in Fuel - Test" for the proper repairs.
Result: Air is not in the system.
Proceed to Test Step 6.
6. Check Fuel Pressure Sensor (1)
A. Record the fuel pressure from Cat ET. Record the value in Table 4.
B. Remove fuel pressure sensor (1).
C. Install a 8t-7860 Connector into the port of the pressure sensor .
D. Install the 110-6349 Fitting As onto the 8t-7860 Connector.
E. Install a 8t-0855 Pressure Gauge onto a 6v-3990 Coupler.
F. Install the 6v-3990 Coupler onto the 110-6349 Fitting As.
G. Record the fuel pressure from Cat ET and on the pressure gauge. Record the data in Table 4.
Pressure Sensor
Result: The gauge value of the fuel pressure is within 69 kPa (10 psi) of the fuel pressure reading shown in ET.
Proceed to Test Step 5.
Result: The gauge value of the fuel pressure is not within 69 kPa (10 psi) of the fuel pressure reading shown in ET.
Repair: Replace the pressure sensor. Verify that the problem has been resolved.
If the problem is not resolved, proceed to Test Step 7.
7. Replace the Transfer Pump
A. Replace the transfer pump.
For information about testing the transfer pump, Refer to Testing and Adjusting, "Fuel System Pressure - Test".
Transfer Pump
Result: The transfer pump was replaced.
Repair: Reset all active codes and clear all logged codes by using Cat® ET.
Verify that the problem has been resolved.
