INSPECTION

PROCEDURE

1. INSPECT AUTO HIGH BEAM SWITCH

*a	Component without harness connected (Auto High Beam Switch)

(a) Check the resistance.

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

Standard Resistance:

Tester Connection	Switch Condition	Specified Condition
If the result is not as specified, replace the auto high beam switch.
4 (+B) - 1 (E)	Auto high beam switch ON	Below 1 Ω
4 (+B) - 1 (E)	Auto high beam switch OFF	10 kΩ or higher

(b) Check the illumination.

(1) Apply battery voltage to the connector and check the illumination condition.

OK:
