Inspection Procedure

NOTE: The intelligent 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.
    3. Turn the ignition switch OFF and wait for 10 seconds.
    4. Connect the intelligent tester to the DLC3.
    5. Turn the ignition switch ON and press the intelligent tester switch ON.
    6. Enter the following menus: 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.

      Fig 1: DTC Reference Chart

      NOTE: If the 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 all be stored.
  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 by the intelligent tester. 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. Clear the DTCs (See DTC CHECK / CLEAR  ).
    2. On the intelligent tester, select the following menu items: DIAGNOSIS / ENHANCED OBD II / SYSTEM CHECK / EVAP SYS CHECK / AUTO OPERATION.
    3. 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 the repair is completed. After this confirmation, check for pending DTCs. If no DTC is displayed, the EVAP system is normal.

  3. PERFORM EVAP SYSTEM CHECK (MANUAL OPERATION) 
    Fig 2: EVAP Pressure Graph (Manual Operation)
    G04828299Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    NOTE:
    • In the EVAP SYSTEM CHECK (MANUAL OPERATION), the series of 5 EVAP SYSTEM CHECK steps is performed manually by the intelligent tester.
    • Do not perform the EVAP SYSTEM CHECK when the fuel tank is more than 90% full because the cut-off valve may be closed, 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. Clear the DTCs (See DTC CHECK / CLEAR  ).
    2. On the intelligent tester, select the following menu items: DIAGNOSIS / ENHANCED OBD II / SYSTEM CHECK / EVAP SYS CHECK / MANUAL OPERATION.
  4. PERFORM EVAP SYSTEM CHECK (STEP 1/5)

  36. PERFORM EVAP SYSTEM CHECK (AUTO OPERATION) 
    NOTE:
    • In the EVAP SYSTEM CHECK (AUTO OPERATION), the series of 5 EVAP SYSTEM CHECK steps are performed automatically by the intelligent tester. 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, 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 the DTCs (See DTC CHECK / CLEAR  ).
    2. On the intelligent tester, select the following menu items: 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.
