PROCEDURE


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


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

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

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


      Body Electrical > Combination Meter > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      ODO/TRIP Change SW ODO/TRIP switch OFF or ON

      OFF: Switch released

      ON: Switch pushed

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


    1. Disconnect the K3 combination meter assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      K3-4 (ODO) - K90-4 (A/B) Always Below 1 Ω
      K3-26 (SW3) - K90-5 (E) Always Below 1 Ω
      K3-4 (ODO) - Body ground Always 10 kΩ or higher
      K3-26 (SW3) - Body ground Always 10 kΩ or higher
      Result
