Inspection Procedure

NOTE: The Techstream 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 to the ON position.
    3. Turn the ignition switch off and wait for 10 seconds.
    4. Connect the Techstream to the DLC3.
    5. Turn the ignition switch to the ON position and turn the Techstream on.
    6. Select the following menu items: Powertrain/Engine and ECT/Trouble 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 reference pressure difference between the first and second checks is greater than the specification, ail the DTCs relating to the reference pressure (P043E, P043F, P2401, P2402 and P2419) are stored.

  2. PERFORM EVAPORATIVE SYSTEM CHECK (AUTOMATIC MODE) 
    NOTE:
    • The Evaporative System Check (Automatic Mode) consists of 5 steps performed automatically by the Techstream. It takes a maximum of approximately 18 minutes.
    • Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the cut-off valve may be closed, making the fuel tank leak check unavailable.
    • Do not run the engine during this operation.
    • 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 Evaporative System Check, keep the temperature below 35°C (95°F).
    1. Clear the DTCs (See DTC CHECK/CLEAR  ).
    2. On the tester, select the following menu items: Powertrain/Engine and ECT/Utility/Evaporative System Check/Automatic Mode.
    3. After the Evaporative System Check is completed, check for pending DTCs by selecting the following menu items: Powertrain/Engine and ECT/Trouble Codes/Pending.

      HINT:

      If no pending DTCs are displayed, perform the MONITOR CONFIRMATION (see "Diagnostic Help" menu). After this confirmation, check for pending DTCs. If no DTCs are displayed, the EVAP system is normal.

  3. PERFORM EVAPORATIVE SYSTEM CHECK (MANUAL MODE) 
    Fig 2: EVAP Pressure Malfunction Chart - Manual Mode
    G06276424Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    NOTE:
    • In the Evaporative System Check (Manual Mode), perform the series of 5 Evaporative System Check steps manually using the Techstream.
    • Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the cut-off valve may be closed, making the fuel tank leak check unavailable.
    • Do not run the engine during this operation.
    • 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 Evaporative System Check, keep the temperature below 35°C (95°F).
    1. Clear the DTCs (See DTC CHECK/CLEAR  ).
    2. Select the following menu items: Powertrain/Engine and ECT/Utility/Evaporative System Check/Manual Mode.
  4. PERFORM EVAPORATIVE SYSTEM CHECK (STEP 1/5) 
    1. Check the EVAP pressure in step 1/5.

    NEXT: Go to step 36 

  36. PERFORM EVAPORATIVE SYSTEM CHECK (AUTOMATIC MODE) 
    NOTE:
    • The Evaporative System Check (Automatic Mode) consists of 5 steps performed automatically by the Techstream. It takes a maximum of approximately 18 minutes.
    • Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the cut-off valve may be closed, making the fuel tank leak check 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 Evaporative System Check, keep the temperature below 35°C (95°F).
    • Clear the DTCs (See DTC CHECK/CLEAR  ).
    • On the Techstream, select the following menu items: Powertrain/Engine and ECT/Utility/Evaporative System Check/Automatic Mode.
    • After the Evaporative System Check is completed, check for pending DTCs by selecting the following menu items: Powertrain/Engine and ECT/Trouble Codes/Pending.

      HINT:

      If no pending DTCs are found, the repair has been successfully completed.
