INSPECTION PROCEDURE

PROCEDURE


  1. READ VALUE USING INTELLIGENT TESTER (ODO/TRIP CHANGE SW)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the tester on.

    4. Enter the following menus: Body Electrical / Combination Meter / Data List.

    5. Check the values by referring to the table below.

      Combination Meter
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      ODO/TRIP Change SW ODO/TRIP change switch/OFF or ON OFF: ODO/TRIP change switch released -
      ON: ODO/TRIP change switch pressed
      OK
      The value displayed on the intelligent tester changes with the actual ODO/TRIP change switch operation.

  2. INSPECT TRIP SWITCH


    1. A01DPLOE01

      Disconnect the G16 trip switch connector.

    2. Inspect the ODO/TRIP switch


      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        for LHD
        Tester Connection Switch Condition Specified Condition
        4 (A/B) - 1 (E) ODO/TRIP switch on (pushed) Below 1 Ω
        ODO/TRIP switch off (Not pushed) 1 MΩ or higher
        for RHD
        Tester Connection Switch Condition Specified Condition
        1 (A/B) - 4 (E) ODO/TRIP switch on (pushed) Below 1 Ω
        ODO/TRIP switch off (Not pushed) 1 MΩ or higher

  3. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - TRIP SWITCH)


    1. Disconnect the G6 meter connector.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      for LHD
      Tester Connection Condition Specified Condition
      G6-11 (RSET) - G16-4 (A/B) Always Below 1 Ω
      G6-11 (RSET) - Body ground Always 10 kΩ or higher
      for RHD
      Tester Connection Condition Specified Condition
      G6-11 (RSET) - G16-1 (A/B) Always Below 1 Ω
      G6-11 (RSET) - Body ground Always 10 kΩ or higher
