B. Check for associated diagnostic trouble codes.
   
Associated Diagnostic Trouble 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.
Refer to Troubleshooting, "Fuel Pressure Is Low" for the proper troubleshooting procedure. STOP.
Result: A 3427-5, 3427-6, 5423-5 or 5423-6 code is active.
Refer to Troubleshooting, "Solenoid Valve - Test" for the proper troubleshooting procedure.
   
2. Record the Enhanced Troubleshooting Indicator (ETI) Code
A. Establish communication between Caterpillar Electronic Technician (ET) and the Electronic Control Module (ECM). Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. The ETI code is located in the "Status" screen under "Enhanced Troubleshooting Information (ETI) - ARD". Record the Enhanced Troubleshooting Indicator (ETI) code.
ETI codes are not available for (2) or -18 codes.
   
Recorded 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 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 ARD Fuel Pump
A. Turn the keyswitch to the ON position. 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) in order 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 the OFF position.
F. Check the voltage at the battery.
   
Voltage within 3 VDC of the battery voltage
   
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.
