Inspection Procedure

NOTE: A hand-held tester is required to conduct the following diagnostic troubleshooting procedure.

HINT:

  1. CONFIRM DTC 
    1. Turn the ignition switch off and wait for 10 seconds.
    2. Turn the ignition switch on (IG).
    3. Turn the ignition switch off and wait for 10 seconds.
    4. Connect the hand-held tester to the DLC3.
    5. Turn the ignition switch on (IG) and turn the tester on.
    6. Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES.
    7. Confirm DTCs and freeze frame data.

    If any EVAP system DTCs are set, the malfunctioning area can be determined using the table below.

    NOTE: If the 0.02 inch reference pressure difference between the first and second checks is greater than the specification, the DTCs corresponding to the reference pressure (P043E, P043F, P0441, P0455, P0456, P2401 and P2420) will be all stored.
    1. NEXT: Go to next step. 
  2. PERFORM EVAP SYSTEM CHECK (AUTO OPERATION) 
    NOTE:
    • In the EVAP SYSTEM CHECK (AUTO OPERATION), the series of 5 EVAP SYSTEM CHECK steps is performed automatically. It takes a maximum of approximately 18 minutes.
    • Do not perform the EVAP SYSTEM CHECK when the fuel tank is more than 90 % full because the cut-off valve may be closed and making the leak check of the fuel tank unavailable.
    • Do not run the engine in this step.
    • When the temperature of the fuel is 35°C (95°F) or more, a large amount of vapor forms and any check results become inaccurate. When performing the EVAP SYSTEM CHECK, keep the temperature below 35°C (95°F).
    1. Connect the hand-held tester to the DLC3.
    2. Clear DTCs (see DTC CHECK/CLEAR  ).
    3. Select the following menu items on the tester: DIAGNOSIS / ENHANCED OBD II / SYSTEM CHECK / EVAP SYS CHECK / AUTO OPERATION.
    4. After the EVAP SYSTEM CHECK is completed, check for pending DTCs by selecting the following menu items: DIAGNOSIS / ENHANCED OBD II / DTC INFO / PENDING CODES.

    HINT:

    If no pending DTC is displayed, perform the Monitor Confirmation after this repair is completed. After this confirmation, check for pending DTCs. If no DTC is displayed, the EVAP system is normal.

    1. NEXT: Go to next step. 
  3. PERFORM EVAP SYSTEM CHECK (MANUAL OPERATION)

    • Do not perform the EVAP SYSTEM CHECK when the fuel tank is more than 90 % full because the cut-off valve may be closed and making the leak check of the fuel tank unavailable.
    • Do not run the engine in this step.
    • When the temperature of the fuel is 35°C (95°F) or more, a large amount of vapor forms and any check results become inaccurate. When performing the EVAP SYSTEM CHECK, keep the temperature below 35°C (95°F).
    1. Connect the hand-held tester to the DLC3.

    • If the system has leaks, a whistling sound will be heard.
    • Disconnect the hose between the canister and the fuel tank from the canister. Close the canister hose connected to the fuel tank, and conduct an inspection. In this way, the fuel tank can be excluded as an area suspected of causing fuel leaks.

    1. NEXT: Go to step 37 
  37. PERFORM EVAP SYSTEM CHECK (AUTO OPERATION) 
    NOTE:
    • In the EVAP SYSTEM CHECK (AUTO OPERATION), the series of 5 EVAP SYSTEM CHECK steps is performed automatically. It takes a maximum of approximately 18 minutes.
    • Do not perform the EVAP SYSTEM CHECK when the fuel tank is more than 90 % full because the cut-off valve may be closed and making the leak check of the fuel tank unavailable.
    • Do not run the engine in this step.
    • When the temperature of the fuel is 35°C (95°F) or more, a large amount of vapor forms and any check results become inaccurate. When performing an EVAP SYSTEM CHECK, keep the temperature below 35°C (95°F).
    1. Clear DTCs (see DTC CHECK/CLEAR  ).
    2. Select the following menu items on the tester: DIAGNOSIS / ENHANCED OBD II / SYSTEM CHECK / EVAP SYS CHECK / AUTO OPERATION.
    3. After the SYSTEM CHECK is completed, check for pending DTCs by selecting the following menu items: DIAGNOSIS / ENHANCED OBD II / DTC INFO / PENDING CODES.

    HINT:

    If no pending DTC is found, the repair has been successfully completed.
