The task of the humidity sensor (HUS) is to transmit information about the passenger compartment's humidity to the Climate control module (CCM).
The sensor is part of the optional system for air quality together with the Air quality sensor (AQS) and a particle filter.
The humidity sensor is via serial communication to the Central electronic module (CEM), which transmits the information to the Climate control module (CCM) on the CAN network.
All information processing then occurs in the Climate control module (CCM).
The sensor is in the holder for the rear view mirror and is powered and diagnosed by the Central electronic module (CEM).
