SUNLOAD / Light Sensor
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2015 Jaguar XKR-S, 2015 Jaguar XKR, 2015 Jaguar XK, 2014 Jaguar XKR-S, and 2014 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.
The sunload/light sensor consists of 2 photoelectric cells that provide the 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 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 LED (light emitting diode).
For additional information, refer to: Exterior Lighting (Description and Operation) / Anti-Theft - Active (Description and Operation).
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.
