PROCEDURE


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


    1. Using the GTS, read the Data List Click here.

      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 GTS changes with the actual ODO/TRIP change switch operation.

    OK

  2. INSPECT TRIP SWITCH


    1. A01XH0KE01

      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

    NG

    OK

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


    1. Disconnect the G6 combination meter assembly connector.

    2. Disconnect the G16 trip switch connector.

    3. 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

    OK
