Standard Resistance:

Tester Connection	Switch Condition	Specified Condition
5 (SS1) - 6 (GND)	Not pushed	10 kΩ or higher
1 (SS2) - 6 (GND)	Not pushed	10 kΩ or higher
5 (SS1) - 6 (GND)	Pushed	Below 1 Ω
1 (SS2) - 6 (GND)	Pushed	Below 1 Ω

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

(b) Apply battery voltage between the terminals of the switch, and check the illumination condition of the engine switch.
