INSPECTION

PROCEDURE

1. INSPECT OUTER MIRROR SWITCH ASSEMBLY (w/o Retract Mirror)

(a) Check the resistance.

(1) Select "L" on the left/right adjustment switch.

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

Standard Resistance:

Tester Connection	Condition		Specified Condition
4 (VL) - 8 (B) 6 (M+) - 7 (E)	UP	Pressed	Below 1 Ω
4 (VL) - 8 (B) 6 (M+) - 7 (E)	UP	Not pressed	10 kΩ or higher
4 (VL) - 7 (E) 6 (M+) - 8 (B)	DOWN	Pressed	Below 1 Ω
4 (VL) - 7 (E) 6 (M+) - 8 (B)	DOWN	Not pressed	10 kΩ or higher
5 (HL) - 8 (B) 6 (M+) - 7 (E)	LEFT	Pressed	Below 1 Ω
5 (HL) - 8 (B) 6 (M+) - 7 (E)	LEFT	Not pressed	10 kΩ or higher
