Inspection Procedure

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

HINT:

  1. CONFIRM DTC 
    1. Turn the ignition switch to OFF and wait for 10 seconds.
    2. Turn the ignition switch to ON.
    3. Turn the ignition switch to OFF and wait for 10 seconds.
    4. Connect a Techstream to the DLC3.
    5. Turn the ignition switch to ON.
    6. Turn the tester ON.
    7. Select the following menu items: Powertrain / Engine and ECT / Trouble Codes.
    8. 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 Malfunctioning Area Reference Chart

  2. PERFORM EVAPORATIVE SYSTEM CHECK (AUTOMATIC MODE) 
    NOTE:
    • The Evaporative System Check (Automatic Mode) consists of five steps performed automatically by a 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. If the cut-off valve is closed, the fuel tank leak check is not possible.
    • 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 DTCs (See DTC CHECK / CLEAR  ).
    2. 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 CONFIRMATION DRIVING PATTERN . 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 Graph (Manual Mode)
    G05398636Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    NOTE:
    • In the Evaporative System Check (Manual Mode), perform the series of 5 Evaporative System Check steps manually using a 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. If the cut-off valve is closed, the fuel tank leak check is not possible.
    • 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 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)

      Disconnect the hose between the canister and the fuel tank from the canister. Block the canister side and conduct an inspection. In this way, the fuel tank can be excluded as an area suspected of causing fuel leaks.

    NEXT:  Go to step  36

  29. REPLACE CANISTER ASSEMBLY 
    1. Replace the canister assembly (See REMOVAL ).
      NOTE: When replacing the canister, check the canister pump module interior and related pipes for water, fuel and other liquids. If liquids are present, check for disconnections and/or cracks in the following: 1) the pipe from the air inlet port to the canister pump module; 2) the canister filter; and 3) the fuel tank vent hose.

  31. REPAIR OR REPLACE HARNESS OR CONNECTOR 

    NEXT:  Go to step  36

  32. REPLACE PURGE LINE HOSE (INTAKE MANIFOLD - PURGE VSV) 

    NEXT:  Go to step  36

  33. INSPECT INTAKE MANIFOLD (EVAP PURGE PORT) 
    1. Check that the EVAP purge port of the intake manifold is not clogged. If necessary, replace the intake manifold.

    NEXT:  Go to step  36

  34. REPLACE ECM 
    1. Replace the ECM (See REMOVAL  ).

    NEXT:  Go to step  36

  35. REPAIR OR REPLACE PARTS AND COMPONENTS INDICATED BY OUTPUT DTCS 
    1. Repair the malfunctioning areas indicated by the DTCs that had been confirmed when the vehicle was brought in.

    NEXT: Go to step 36 

  36. PERFORM EVAPORATIVE SYSTEM CHECK (AUTOMATIC MODE) 
    NOTE:
    • The Evaporative System Check (Automatic Mode) consists of five steps performed automatically by a 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. If the cut-off valve is closed, the fuel tank leak check is not possible.
    • 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. 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 found, the repair has been successfully completed.
