CAUTION / NOTICE / HINT

Note

When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.

PROCEDURE


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


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

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

    5. Read the Data List according to the display on the GTS.

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


    1. Disconnect the K20 combination meter assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      K111-3 (A/B) - K20-1 (ODO) Always Below 1 Ω
      K111-1 (E) - K20-5 (SW3) Always Below 1 Ω
      K111-3 (A/B) or K20-1 (ODO) - Body ground Always 10 kΩ or higher
