Description and Operation

Description

The photo sensor is located in the center of the defroster nozzles.

The photo sensor contains a photovoltaic (sunlight-sensitive) diode. Solar radiation received by its light-receiving part generates an electromotive force proportional to the amount of radiation received, which is then transmitted to the automatic temperature control module so that solar radiation compensation can be performed.

  2. Connect the KDS/GDS.

  3. Direct intense light onto the photo sensor using a lamp, and check the change in output voltage.
