Headlamp Dimmer Switch: Testing and Inspection
The headlight beams can be turned to high and low alternately by pulling the switch lever up to the limit. Also, the passing light can be flashed by
operating the switch lever within the range before the dimmer switch has been changed over. The switch lever returns automatically to its original
position.
Check the continuity between the terminals of the dimmer passing switch.
Repair or replace the switch when the result of inspection is found abnormal.
