Troubleshooting Test Steps Values Results
1. Check for Codes
A. Apply electrical power to the engine.
B. Connect Cat® Electronic Technician (ET) to the service tool connector.
C. Determine if a code is active or logged.
Codes
Result: An 18–7, 18–11, 18–12, 1076–7, 1076–11 or 1076-12 code is present.
Repair: A failed FCV has been detected.
Note: If the pressure is not less than 5000 kPa (725 psi) (gauge) after 10 minutes, vent the pressure from the fuel system. Refer to Systems Operation/Testing and Adjusting, Fuel Rail Pressure - Release, for information.
Replace the FCV.
Proceed to Test Step 9.
Result: An 18–8 or 1076-8 code is present.
Proceed to Test Step 2.
Result: A 1028–6 or 3597-6 code is active.
