AUTO LIGHT SENSOR FUNCTION
id091800102200
!
The auto light sensor contains upward and forward illumination sensors which detect the level of illumination
above and in front of the vehicle respectively.
!
If the forward illumination level sensor detects a bright level of illumination in front of the vehicle and the upward
illumination level sensor detects a dark level when the headlights are on, the microcomputer in the auto light
sensor prepares for turning off the lights. If both illumination level sensors detect that is necessary to turn off
the headlights, they are turned off with optimal timing.
