Tester Connection	Condition	Specified Condition
z5-14 (MIST) -z5-5 (E)	MIST position	Below 1 Ω
z5-14 (MIST) -z5-5 (E)	Except MIST position	10 kΩ or higher
z5-10 (W_OFF) - z5-5 (E)	OFF position	Below 1 Ω
z5-10 (W_OFF) - z5-5 (E)	Except OFF position	10 kΩ or higher
z5-13 (+S) - z5-5 (E)	AUTO position	Below 1 Ω
z5-13 (+S) - z5-5 (E)	Except AUTO position	10 kΩ or higher
z5-11 (+1) - z5-5 (E)	LO position	Below 1 Ω
z5-11 (+1) - z5-5 (E)	Except LO position	10 kΩ or higher
z5-12 (+2) - z5-5 (E)	HI position	Below 1 Ω
z5-12 (+2) - z5-5 (E)	Except HI position	10 kΩ or higher

Front Washer Switch

Tester Connection	Condition	Specified Condition
z5-15 (WF) - z5-5 (E)	ON position	Below 1 Ω
z5-15 (WF) - z5-5 (E)	OFF position	10 kΩ or higher

Auto Sensitivity Adjustment Switch

Tester Connection	Condition	Specified Condition
z5-4 (VR) - z5-5 (E)	P1 position	1102 to 1218 Ω
z5-4 (VR) - z5-5 (E)	P2 position	570 to 630 Ω
z5-4 (VR) - z5-5 (E)	P3 position	256.5 to 283.5 Ω
