DESCRIPTION
The solar sensor (automatic light control sensor) is installed on the upper side of the instrument panel. It detects
sunlight to control air conditioning AUTO mode. The output voltage from the solar sensor (automatic light
control sensor) varies in accordance with the amount of sunlight. When the amount of sunlight increases, the
output voltage increases. As the sunlight decreases, the output voltage decreases. The A/C amplifier detects
changes in the output voltage from the solar sensor (automatic light control sensor).
