Inspection Procedure

NOTE: The Techstream is required to conduct the following diagnostic troubleshooting procedure.

HINT

  1. CONFIRM DTC 
    1. Turn the engine switch off and wait for 10 seconds
    2. Turn the engine switch on (IG)
    3. Turn the engine switch off and wait for 10 seconds
    4. Connect the Techstream to the DLC3.
    5. Turn the engine switch on (IG) and turn the Techstream ON
    6. Enter the following menus" Powertrain / Engine / 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, all 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 five 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 35C (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. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG) and turn the Techstream ON.
    3. Clear DTCs (See DTC CHECK/CLEAR )
    4. Enter the following menus Powertrain / Engine / Utility / Evaporative System Check / Automatic Mode
    5. After the Evaporative System Check is completed, check for pending DTCs by entering the following menus. Powertrain / Engine / Trouble Codes

      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 Reference Graph (Manual Mode)
    G05751762Courtesy 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 35C (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. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG) and turn the Techstream ON

    NEXT: Go to step  37

  37. PERFORM EVAPORATIVE SYSTEM CHECK (AUTOMATIC MODE) 
    NOTE:
    • The Evaporative System Check (Automatic Mode) consists of five 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 an Evaporative System Check, keep the temperature below 35°C (95°F).
    1. Clear DTCs (See DTC CHECK/CLEAR ).
    2. Enter the following menus Powertrain / Engine / Utility / Evaporative System Check / Automatic Mode
    3. After the Evaporative System Check is completed, check for pending DTCs by entering the following menus Powertrain / Engine / Trouble Codes.
