Mercedes-Benz ML320. Service manual - part 690

 

 

MODEL 163 up to 31.8.01 with CODE (580) Air conditioning or Tempmatic for USA  

MODEL 163 as of 1.9.01 with CODE (580a) Automatic air conditioning  

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.

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 high level of control accuracy is guaranteed.

In-car 
temperature 
sensor, task

The in-car temperature sensor (B10/4) with suction jet nozzle records 
the interior temperature and conveys this to the AAC push-button 
control module. The suction jet nozzle ensures air from the vehicle 
interior flows evenly around the in-car temperature sensor (B10/4).

In-car temperature 
sensor, location

The in-car temperature sensor (N22b1) is located below in the temperature selector 
wheel of the AAC push-button control module.

 

 

In-car temperature 
sensor, task

The in-car temperature sensor (N22b1) records the in-car temperature and sends it 
to the AAC push-button control module (N22).

 

 

In-car temperature 
sensor, function

The recorded in-car temperature value is compared by the AAC push-button control 
module with the setting in the temperature selector wheel whereupon it authorizes a 
corresponding adjustment to the blending air flap to be made depending upon the 
result.

Center nozzle vent air 
temperature sensor, 
location

The center nozzle vent air temperature sensor (B10/24) is located to the left of 
the air duct's center nozzle below the instrument panel.

 

 

Center nozzle vent air 
temperature sensor, 
task

The center nozzle vent air temperature sensor (B10/24) records the temperature 
of the air flowing out of the center nozzle and sends it to the AAC push-button 
control module (N22).

 

 

Center nozzle vent air 
temperature sensor, 
function

The vent air's recorded temperature value is compared by the AAC push-button 
control module (N22) with the setting in the temperature selector wheel 
whereupon it authorizes a corresponding adjustment to the blending air flap to 
be made depending upon the result.

temperature sensor, 
location

The front footwell vent air temperature sensor (B10/25) is located to the left of 
the automatic air conditioning box below the instrument panel.

 

 

Front footwell vent air 
temperature sensor, 
task

The front footwell vent air temperature sensor (B10/25) records the temperature 
of the air flowing in the front footwell and sends it to the AAC push-button 
control module (N22).
