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.

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.
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.
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
• Is there any malfunction?
Yes
Replace the check valve and perform the repair completion verification.
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)
No
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
• 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.
No
Replace the PCM.
