      Tester Connection Switch Position Specified Condition
      7 (SS1) - 5 (GND) Not pushed 10 kΩ or higher
      2 (SS2) - 5 (GND) Not pushed 10 kΩ or higher
      7 (SS1) - 5 (GND) Pushed Below 1 Ω
      2 (SS2) - 5 (GND) Pushed Below 1 Ω

      If the result is not as specified, replace the engine switch.

    2. Apply battery voltage between the terminals of the switch, and check the illumination condition of the switch.

      HINT:

      • If the positive (+) lead and the negative (-) lead are incorrectly connected, the engine switch indicator will not illuminate.
      • If the voltage is too low, the indicator will not illuminate.

      OK
