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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      2 (TRIP) - 1

      ODO/TRIP switch on

      (pushed)

      		 Below 1 Ω
      2 (TRIP) - 1

      ODO/TRIP switch off

      (not pushed)

      		 10 kΩ or higher
      3 (DISP) - 1*1

      DISP switch on

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


    1. Disconnect the D7 combination meter assembly connector.

    2. Disconnect the D64 trip switch connector.

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

      Standard Resistance (Check for Open)
      Tester Connection Condition Specified Condition
      D7-34 (DISP) - D64-3 (DISP)*1 Always Below 1 Ω
      D7-35 (CS) - D64-8 (CS)*2 Always Below 1 Ω
      D7-36 (TRIP) - D64-2 (TRIP) Always Below 1 Ω
      Standard Resistance (Check for Short)
      Tester Connection Condition Specified Condition
      D7-34 (DISP) or D64-3 (DISP) - Body ground*1 Always 10 kΩ or higher
      D7-35 (CS) or D64-8 (CS) - Body ground*2 Always 10 kΩ or higher
      D7-36 (TRIP) or D64-2 (TRIP) - Body ground Always 10 kΩ or higher

      *1: except TFT Meter Type

      *2 : w/ km/h / MPH Switch
