DESCRIPTION

The meter CPU receives ODO/TRIP change switch signal from the light control rheostat via the direct line.

Tech Tips

The whole light control rheostat should be replaced if the ODO/TRIP switch is malfunctioning.

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.

  2. INSPECT TRIP SWITCH


    1. B001HVME03

      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

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


    1. Disconnect the G304*1, G6 *2combination meter assembly connector.


      • *1: except 5L-E

      • *2: for 5L-E

    2. Disconnect the G16 trip switch connector.

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

      Standard Resistance (except 5L-E)
      for LHD
      Tester Connection Condition Specified Condition
      G304-14 (RSET) - G16-4 (A/B) Always Below 1 Ω
      G304-14 (RSET) - Body ground Always 10 kΩ or higher
      for RHD
      Tester Connection Condition Specified Condition
      G304-14 (RSET) - G16-1 (A/B) Always Below 1 Ω
      G304-14 (RSET) - Body ground Always 10 kΩ or higher
      Standard Resistance (for 5L-E)
      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
