  2. INSPECT TRIP SWITCH


    1. A001FF0E02
      *1 ODO/TRIP Switch
      *2 TRIP RESET Switch
      *3 Trip Switch
      *4 Component without harness connected: (Trip Switch)

      Standard resistance
      Tester Connection Switch Condition Specified Condition
      5 (RSET) - 6 (E) RESET switch ON (Pushed) Below 1 Ω
      RESET switch OFF (Not pushed) 10 kΩ or higher
      7 (A/B) - 6 (E) ODO/TRIP switch ON (Pushed) Below 1 Ω
      ODO/TRIP switch OFF (Not pushed) 10 kΩ or higher

    NG

    OK

  3. CHECK HARNESS AND CONNECTOR (NO. 1 METER ECU - TRIP SWITCH AND BODY GROUND)


    1. A001FO1E01
      *1 Rear view of wire harness connector: (to No. 1 Meter ECU)
      *2 Rear view of wire harness connector: (to Trip Switch)

      Disconnect the L10 meter connector.

      Standard resistance
      Tester Connection Condition Specified Condition
      L10-4 (A/B) - L45-7 (A/B) Always Below 1 Ω
      L10-5 (RSET) - L45-5 (RSET)
      L45-6 (E) - Body ground
      L10-4 (A/B) or L45-7 (A/B) - Body ground Always 10 kΩ or higher
      L10-5 (RSET) or L45-5 (RSET) - Body ground

    OK

    REPLACE NO. 1 METER ECU

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR
