Function requirements 

Function 

The air quality sensor (1) is a NOx sensor that measures the nitrogen oxide and oxygen concentration in the exhaust gas and sends the signal to the front signal acquisition and actuation module control unit.

The front signal acquisition and actuation module control unit forwards the signal to the upper or lower control panel control unit depending on the model and equipment installed.

The upper or lower control panel control unit is finally connected to the control for climate control via LIN.

The control for climate control regulates the pollutant-controlled air-recirculation mode based on this.
