INSPECTION

PROCEDURE

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

(a) The L position of the left/right adjustment switch: Measure the resistance according to the value(s) in the table below.

Standard Resistance (for Left Side):

Tester Connection	Condition	Specified Condition
4 (MLV) - 8 (B) 6 (M+) - 7 (E)	UP	Below 1 Ω
4 (MLV) - 8 (B) 6 (M+) - 7 (E)	OFF	10 kΩ or higher
4 (MLV) - 7 (E) 6 (M+) - 8 (B)	DOWN	Below 1 Ω
4 (MLV) - 7 (E) 6 (M+) - 8 (B)	OFF	10 kΩ or higher
5 (MLH) - 8 (B) 6 (M+) - 7 (E)	LEFT	Below 1 Ω
5 (MLH) - 8 (B) 6 (M+) - 7 (E)	OFF	10 kΩ or higher
5 (MLH) - 7 (E) 6 (M+) - 8 (B)	RIGHT	Below 1 Ω
5 (MLH) - 7 (E) 6 (M+) - 8 (B)	OFF	10 kΩ or higher

(b) The R position of the left/right adjustment switch: Measure the resistance according to the value(s) in the table below.

Standard Resistance (for Right Side):

Tester Connection	Condition	Specified Condition
3 (MRV) - 8 (B) 6 (M+) - 7 (E)	UP	Below 1 Ω
3 (MRV) - 8 (B) 6 (M+) - 7 (E)	OFF	10 kΩ or higher
3 (MRV) - 7 (E) 6 (M+) - 8 (B)	DOWN	Below 1 Ω
3 (MRV) - 7 (E) 6 (M+) - 8 (B)	OFF	10 kΩ or higher
2 (MRH) - 8 (B) 6 (M+) - 7 (E)	LEFT	Below 1 Ω
2 (MRH) - 8 (B) 6 (M+) - 7 (E)	OFF	10 kΩ or higher
2 (MRH) - 7 (E) 6 (M+) - 8 (B)	RIGHT	Below 1 Ω
2 (MRH) - 7 (E) 6 (M+) - 8 (B)	OFF	10 kΩ or higher

2. INSPECT OUTER MIRROR SWITCH ASSEMBLY (w/ Memory)

(a) Check the switch functions.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 (M+) - 2 (E)	Mirror adjust switch pressed up	90 to 110 Ω
	Mirror adjust switch pressed down	437 to 503 Ω
	Mirror adjust switch pressed left	744 to 856 Ω
	Mirror adjust switch pressed right	225 to 275 Ω
	Mirror adjust switch not pressed	10 kΩ or higher
1 (MSW) - 2 (E)	Mirror select switch R	Below 1 Ω
	Mirror select switch L	90 to 110 Ω
	Mirror select switch off	10 kΩ or higher

If the result is not as specified, replace the outer mirror switch assembly.

(b) Check the mirror retract switch.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
8 (MR) - 4 (E2)	Mirror retract switch retract position	Below 1 Ω
7 (MF) - 6 (B)	Mirror retract switch retract position	Below 1 Ω
8 (MR) - 6 (B)	Mirror retract switch return position	Below 1 Ω
7 (MF) - 4 (E2)	Mirror retract switch return position	Below 1 Ω
7 (MF) - 8 (MR)	Always	10 kΩ or higher
