Troubleshooting Test Steps Values Results
1. 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 tank to the fuel transfer pump 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 2.
Result: Leaks were found in the fuel system.
Repair: Repair the leaks.
Verify that the problem is resolved.
2. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Check for an active associated code.
Codes
Result: An associated code is active.
Repair: Troubleshoot the associated code.
Result: There are no associated codes.
Proceed to Test Step 3.
3. Check for Event Codes
A. Connect Cat ET.
C. Look for active codes that are associated with the system for the event code.
Event Codes
Result: An E1569, 1381, or 5417 code is present.
Proceed to Test Step 4.
Result: Both an E1569 or 5417 AND an E2172 or 1381 are present together.
Proceed to Test Step 4.
Result: An E2172 or 1381 is present.
Proceed to Test Step 9.
4. Check for Power to the Clean Fuel Module Pump
A. Turn the keyswitch to the OFF position.
B. Disconnect the wiring harness from the clean fuel module pump.
C. Turn the keyswitch to the ON position.
D. Connect Cat ET.
E. Use the "Electric Fuel Transfer Pump Relay Override" to energize the clean fuel module fuel pump.
F. Measure the voltage between pin 2 and pin 3 on the connector for the clean fuel module pump.
G. Measure the voltage between pin 2 and pin 4 on the connector for the clean fuel module pump.
System Voltage
Result: The voltage at the clean fuel pump module connector is equal to system voltage.
Proceed to Test Step 5.
Result: The voltage at the clean fuel pump module connector is NOT equal to system voltage.
There is a problem with the power supply circuit between the clean fuel module pump connector and the battery supply. Check the circuit protection device, clean fuel module (CFM) relay, and the ground for the clean fuel module pump circuit. Refer to the appropriate wiring diagram to troubleshoot the circuit.
5. Inspect the Fuel Supply Lines for Restrictions
A. Visually inspect the fuel lines between the fuel tank and the inlet to the clean fuel module. Inspect the lines for restrictions, pinching, and swelling. Refer to Systems Operation/Testing and Adjusting, "Fuel System - Inspect", for additional information.
B. Check for plugged fuel tank vent lines or a plugged fuel tank suction screen.
Dirt and Debris or Damage
Result: The fuel lines, tank vent, and suction screen are OK.
Proceed to Test Step 6.
Result: The fuel lines, tank vent, and suction screen are NOT OK.
Repair: Replace damaged fuel lines.
Verify that the problem has been resolved.
6. Prime the Fuel System
A. Remove the air in the fuel system by performing a priming cycle.
B. Refer to the Operation and Maintenance Manual for instructions.
Priming
Result: The fuel system is primed.
Proceed to Test Step 7.
7. Check the Clean Fuel Module Pump Pressure
A. Turn the keyswitch to the OFF position.
B. Remove the clean fuel module outlet pressure sensor.
C. Connect a fuel pressure gauge to the port where the sensor was removed from the clean fuel module.
D. Turn the keyswitch to the ON position.
E. Connect Cat ET.
F. Use the "Electric Fuel Transfer Pump Relay Override" to turn on the clean fuel module fuel pump.
G. Monitor the fuel pressure on the gauge.
30 kpa – 150 kpa (4 PSI – 21.5 PSI)
Result: The clean fuel module pump pressure is within specification.
Proceed to Test Step 8.
Result: The clean fuel module pump pressure is NOT within specification.
A failed clean fuel module pump has been detected.
Repair: Replace the clean fuel module pump.
Proceed to Test Step 12.
8. Check for Proper Clean Fuel Module Pump Operation
A. Turn the keyswitch to t
