Troubleshooting Test Step Value Result
1. Check for Codes
A. Apply electrical power to the engine.
B. Connect Cat® Electronic Technician (ET) to the service tool connector.
C. Apply electrical power to the engine.
D. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Refer to the appropriate troubleshooting story.
Result: An E1220 or a 5585–17 code is present.
Proceed to Test Step 2.
Result: An E398, E1106, 157, or a 1440 code is present.
Proceed to Test Step 3.
2. Check the Service History.
A. An E1220 or 5585-17 code can be caused by a recent service on the fuel system. If the high-pressure system was not primed after the last service, this code will log.
B. Prime the fuel system.
C. Apply electrical power to the engine.
D. Connect Cat ET.
E. Clear the fault E1220 or 5585-17 code.
F. Start the engine.
Code
Result: An E1220 or a 5585-17 code came active after clearing.
Proceed to Test Step 4.
Result: An E1220 or a 5585-17 code did not come active.
The high-pressure fuel system was not properly primed.
Proceed to Test Step 12.
3. Perform a "Fuel System Functional Test"
A. Apply electrical power to the engine.
B. Connect Cat ET.
C. Start the engine.
D. Perform the "Fuel System Functional Test".
E. Once the test has completed, remove electrical power from the engine.
F. Wait for 2 minutes to allow the pump diagnostics to run.
G. Apply electrical power to the engine.
H. Connect Cat ET.
I. Check for active diagnostic codes.
Test Successful
Result: The "Fuel System Functional Test" passed successfully and there are no active codes.
Repair Complete.
Result: There was a 1684 or 1077 code present after running the "Fuel System Functional Test".
A failed high-pressure fuel pump has been detected.
Release the pressure in the high-pressure rail by loosening the end plug on one of the last two fuel accumulators. Refer to Testing and Adjusting, "Fuel Rail Pressure - Release" for instructions on how to release the pressurized fuel.
Repair: Replace the high-pressure fuel pump.
Proceed to Test Step 12.
Result: The test failed for an E111F - Fuel Flow Too Low.
A failed high-pressure fuel pump has been detected.
Release the pressure in the high-pressure rail by loosening the end plug on one of the last two fuel accumulators. Refer to Testing and Adjusting, "Fuel Rail Pressure - Release" for instructions on how to release the pressurized fuel.
Repair: Replace the high-pressure fuel pump.
Proceed to Test Step 12.
Result: The test failed for an E111D - Fuel Rail High Pressure Decay Too High
Proceed to Test Step 4.
Result: The test failed for an E111E - Fuel Rail Low Pressure Decay Too High
Proceed to Test Step 4.
4. Verify the Fuel Rail Pressure Sensor Reading
A. Remove electrical power from the engine.
B. Release the pressure in the high-pressure rail by loosening the end plug on one of the last two fuel accumulators. Refer to Testing and Adjusting, "Fuel Rail Pressure - Release" for instructions on how to release the pressurized fuel.
C. Apply electrical power to the engine.
D. Connect Cat ET.
E. Monitor the "Fuel Rail Pressure" parameter in Cat ET.
Fuel Pressure
Result: The "Fuel Rail Pressure" is 0 8 MPa (1160 psi).
