IN-CAR TEMPERATURE SENSOR, LOCATION - GF83.57-P-2115-01GH
The in-car temperature sensor (B10/4) with suction jet nozzle is located on the left of the center console next to
the radio.

-Car Temperature Sensor
IN-CAR TEMPERATURE SENSOR, FUNCTION - GF83.57-P-2115-02GH
Function
When the blower is running, air is constantly drawn out of the vehicle interior by a suction jet nozzle for the in-
car temperature sensor (B10/4) to measure the temperature when the ignition is. ON .
The in-car temperature sensor (B10/4) records the interior temperature and conveys it to the AAC push-button
control module, where a comparison is made with the setting on the temperature selector. The blend air flap is
repositioned depending on the result of this.
It is connected to the AAC push-button control module via a separate electric cable.
Constant circulation of interior air at the in-car temperature sensor (B10/4) is achieved by this ventilation and
therefore a hi
gh level of control accuracy is guaranteed.
