SUNLOAD/Light Sensor
The sunload/light sensor consists of 2 photoelectric cells that provide the automatic temperature control (ATC) module with inputs of light intensity; one as sensed coming from the left of the vehicle and one as sensed coming from the right. The inputs are a measure of the solar heating effect on vehicle occupants, and are used by the automatic temperature control (ATC) module to adjust blower speed, temperature and distribution to improve comfort.
NOTE:
The solar sensor is also used as part of the Autolamp feature and also contains the active anti-theft alarm indicator light emitting diode (LED). Refer to Exterior Lighting
and Anti-Theft - Active
article.
The sensor is installed in the center of the instrument panel upper surface and is powered by a 5 V feed from the instrument cluster.
