id0103s4891400

Troubleshooting item	Fuel filling shut off concerns
Description	• Fuel does not shut off properly.
Possible cause	• PCM DTC is stored. • Non-return valve malfunction • Check valve malfunction (Except U.S.A. and CANADA) • Fuel nozzle is not inserted correctly. • Fuel nozzle malfunction • Fuel shut-off valve malfunction Warning • The following troubleshooting flow chart contains the fuel system diagnosis and repair procedures. Read the following warnings before performing the fuel system services: ― Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel. ― Highly pressurized fuel may spray out if the fuel line is cut. Due to the following dangers occurring with a fuel spray, always complete the “Fuel Line Safety Procedure” to prevent the fuel from spraying. (See BEFORE SERVICE PRECAUTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See BEFORE SERVICE PRECAUTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].) • Fuel may cause irritation if it comes in contact with skin and eyes. • If fuel ignites and causes a fire, it may lead to serious injury or death, and damage to property and facilities. ― Fuel is highly flammable and dangerous. Fuel line spills and leakage can cause serious injury or death, and damage to equipment. Always refer to the “Quick Release Connector Removal/Installation (fuel system)” before performing the fuel hose installation, and execute the “Fuel Leakage Inspection” after installation. (See QUICK RELEASE CONNECTOR (FUEL SYSTEM) REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See QUICK RELEASE CONNECTOR (FUEL SYSTEM) REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].) (See AFTER SERVICE PRECAUTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See AFTER SERVICE PRECAUTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].) Caution • Disconnecting/connecting the quick release connector without cleaning it may possibly cause damage to the fuel pipe and quick release connector. Always clean the quick release connector joint area before disconnecting/connecting, and make sure that it is free of foreign material.

Diagnostic Procedure

Step	Inspection	Results	Action
1	VERIFY PCM DTC • Perform the DTC inspection for the PCM. (See DTC INSPECTION.) • Are any DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-G (US))].)
1		No	Go to the next step.
2	DETERMINE IF MALFUNCTION CAUSE IS NON-RETURN VALVE • Remove the fuel-filler pipe. • Make sure non-return valve is installed properly. • Inspect the non-return valve operation. • Is there any malfunction?	Yes	Replace the fuel tank and perform the repair completion verification. (See FUEL TANK REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See FUEL TANK REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
2		No	U.S.A. and CANADA: • Inspect the following: ― Improper use of fuel nozzle ― Inadequate fuel filling speed • Repair or replace the malfunctioning location and perform the repair completion verification. Except U.S.A. and CANADA: • Go to the next step.
3	DETERMINE IF MALFUNCTION CAUSE IS CHECK VALVE • Inspect the check valve. (See CHECK VALVE INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See CHECK VALVE INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].) • Is there any malfunction?	Yes	Replace the check valve and perform the repair completion verification. (See CHECK VALVE REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See CHECK VALVE REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
3		No	Inspect the following: • Improper use of fuel nozzle • Inadequate fuel filling speed Repair or replace the malfunctioning location and perform the repair completion verification.
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED • Install/connect the part removed/disconnected during the troubleshooting procedure. • Has the malfunction symptom been eliminated?	Yes	Complete the symptom troubleshooting. (Explain contents of repair to customer)
Repair completion verification 1		No	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(US)].) • If the CAN communication is normal, perform the diagnosis from Step 1. ― If the malfunction recurs, go to the next step.
Repair completion verification 2	VERIFY IF MALFUNCTION IS CAUSED BY NOT PERFORMING PCM REPROGRAMMING • Verify repair information and verify that there is a new calibration in the PCM. • Is there a new calibration in the PCM?	Yes	Perform the PCM reprogramming and verify if the malfunction symptom was corrected. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
Repair completion verification 2		No	Replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
