Troubleshooting Test Steps Values Results
1. Check for Associated Codes
A. Establish communication between Cat® Electronic Technician (ET) and the Electronic Control Module (ECM) . Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Check for associated codes.
Associated Codes
Result: A 5580-18 or E198 code is not active.
Proceed to Test Step 2.
Result: A 5580-18 or E198 code is active.
Repair: Refer to Troubleshooting, "Fuel Pressure Is Low" for the proper troubleshooting procedure.
Result: A 3427-5, 3427-6, 5423-5 or 5423-6 code is active.
Repair: Refer to Troubleshooting, "Solenoid Valve - Test" for the proper troubleshooting procedure.
2. Record the Enhanced Troubleshooting Indicator (ETI) Code
A. Establish communication between Cat ET and the ECM.
B. The ETI code is located in the "Active Events" or "Logged Events" screen in Cat ET. Record the ETI code.
Note: ETI codes are not available for (2) or -18 codes.
ETI Code
Result: Record the ETI code if present.
Proceed to Test Step 3.
3. Check for External Leaks
A. Check for external leaks. Inspect the fuel lines from the pump to the fuel manifold. Check for pinched lines or leaking lines.
External Leaks
Result: A leak or pinched line was not found.
Proceed to Test Step 4.
Result: A leak or pinched line was found.
Repair: Repair all damaged lines or leaking lines. Perform the "ARD Ignition Test" by using Cat ET. Refer to System Operation and Testing and Adjusting, "ARD Fuel System - Test". If the "ARD Ignition Test" was successful, return the unit to service.
If the "ARD Ignition Test" was not successful, Proceed to Test Step 4.
4. Check for Electrical Power at the Fuel Priming Pump
A. Turn the keyswitch to ON. Do not start the engine.
B. Establish communication between Cat ET and the ECM. Select "Fuel Priming Command Override" or use the manual priming switch (if equipped) to activate the ARD fuel pump. Refer to Troubleshooting, "Cat ET Service Features" for information about service features.
C. Check for voltage between pin 1 and pin 2 on the connector to the fuel priming pump. Check the voltage while the pump is in override. Voltage is not present unless the pump is priming.
D. Deactivate the override.
E. Turn the keyswitch to OFF.
F. Check the voltage at the battery.
3 VDC
Result: The voltage at the ARD fuel pump is within 3 VDC of the battery voltage.
Proceed to Test Step 5.
Result: The voltage at the ARD fuel pump is not within 3 VDC of the battery voltage.
Repair: There is a problem with the power supply circuit to the ARD fuel pump. Check the circuit protection device, the relay, and the ground for the ARD fuel pump circuit. Refer to the machine-specific wiring diagram to troubleshoot the circuit. Perform an "ARD Ignition Test" to verify the repair.

5. Check the Pump
A. Turn the keyswitch to "OFF".
B. Disconnect the ARD fuel line from the pump.
C. Install the required parts listed in Table 2 at the outlet port of the pump.
D. Start the engine.
E. Select the "Aftertreatment Fuel Pump Relay Override" in the ECM using Cat ET to activate the pump.
F. Override the pump and record the pressure from the pressure gauge.
G. Deactivate the override.
H. Turn the keyswitch to OFF.
I. The pressure must be within specifications. The pump pressure must be 1900 120 kPa (275.5 17.4 psi).
1900 120 kPa (275.5 17.4 psi)
Result: The pump is not within specifications.
Repair: Refer to Troubleshooting, "ARD Fuel Supply - Test" for troubleshooting information.
Return the unit to service.
Result: The pump is within specifications.
If you are troubleshooting a E1052 (1) or 3480-17 diagnostic code or a E1053 (1) or 4077-17 diagnostic code with an ETI of 2 or 3, proceed to Test Step 6.
Result: The pump is within specifications.
If you are troubleshooting an E1052 (2) or 3480-18 diagnostic code, proceed to Test Step 7.
If you are troubleshooting a E1053 (2) or 4077-18 diagnostic code, proceed to Test Step 8.
