INSPECTION PROCEDURE

PROCEDURE


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


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    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 LIGHT CONTROL RHEOSTAT


    1. for RHD


      1. Remove the light control rheostat.

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

        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        2 (A/B) - 5 (E) ODO/TRIP change switch pressed Below 1 Ω
        2 (A/B) - 5 (E) ODO/TRIP change switch not pressed 10 kΩ or higher

    2. for LHD

        Remove the light control rheostat.

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

        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        2 (A/B) - 5 (E) ODO/TRIP change switch pressed Below 1 Ω
        2 (A/B) - 5 (E) ODO/TRIP change switch not pressed 10 kΩ or higher

      Disconnect the F16 connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      F16-9 (A/B) - F6-2 (A/B) Always Below 1 Ω
      F16-9 (A/B) - Body ground Always 10 kΩ or higher
