|
Yes
|
Repair or replace the fuel filler cap and perform the repair completion verification.
|
No
|
U.S.A. and CANADA:
• Go to the next step.
Except (U.S.A. and CANADA):
• Go to Step 3.
|

2
|
INSPECT EVAPORATIVE HOSE CONNECTION
• Inspect the evaporative hose between the fuel tank, pressure control valve, charcoal canister main, purge solenoid valve, and the intake manifold. (See EMISSION SYSTEM LOCATION INDEX [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See EMISSION SYSTEM LOCATION INDEX [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
• Is there disconnection in the evaporative hose or damage?
|
Yes
|
Repair or replace the malfunctioning location and perform the repair completion verification.
|
No
|
Go to Step 4.
|
||
3
|
INSPECT EVAPORATIVE HOSE CONNECTION
• Inspect the evaporative hose between the fuel tank, charcoal canister, purge solenoid valve, and the intake manifold. (See EMISSION SYSTEM LOCATION INDEX [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See EMISSION SYSTEM LOCATION INDEX [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
• Is there disconnection in the evaporative hose or damage?
|
Yes
|
Repair or replace the malfunctioning location and perform the repair completion verification.
|
No
|
Go to the next step.
|
||
4
|
INSPECT FUEL SYSTEM FOR FUEL LEAKAGE
• Visually inspect the fuel leakage at the fuel line.
• Is there any leakage?
|
Yes
|
Repair or replace the malfunctioning location and perform the repair completion verification.
|
No
|
Go to the next step.
|
||
5
|
INSPECT PURGE SOLENOID VALVE
• Inspect the airflow of purge solenoid valve. (See PURGE SOLENOID VALVE INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See PURGE SOLENOID VALVE INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
• Is the purge solenoid airflow properly?
|
Yes
|
U.S.A. and CANADA:
• Go to the next step.
Except (U.S.A. and CANADA):
• Go to Step 8.
|
No
|
Repair or replace the malfunctioning location and perform the repair completion verification.
|
||
6
|
INSPECT CHARCOAL CANISTER MAIN
• Inspect the charcoal canister main. (See CHARCOAL CANISTER INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See CHARCOAL CANISTER INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
• Is there cracking or damage in the charcoal canister main?
|
Yes
|
Repair or replace the malfunctioning location and perform the repair completion verification.
|
No
|
Go to the next step.
|
||
7
|
INSPECT CHARCOAL CANISTER SUB
• Inspect the charcoal canister sub. (See CHARCOAL CANISTER INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See CHARCOAL CANISTER INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
• Is there cracking or damage in the charcoal canister sub?
|
Yes
|
Repair or replace the malfunctioning location and perform the repair completion verification.
|
No
|
Remove the fuel injector and visually inspect fuel injector or leakage.
• If there is any malfunction:
|
||
8
|
INSPECT CHARCOAL CANISTER
• Inspect the charcoal canister. (See CHARCOAL CANISTER INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See CHARCOAL CANISTER INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
• Is there cracking or damage in the charcoal canister?
|
Yes
|
Repair or replace the malfunctioning location and perform the repair completion verification.
|
No
|
Remove the fuel injector and visually inspect fuel injector or leakage.
• If there is any malfunction:
|
||
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.
|
||
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))].)
