To our mind, actuators information is reference, so there is only simple search by number.

Climate sensor heater (humidity sender heater) -N340

 

The vehicle is fitted as standard with a climate sensor, which is connected to the roof node. In addition to the air humidity, the sensor also delivers other signals, such as for the window temperature. The signals are acquired and evaluated under the following conditions:

J Climate sensor fitting info set in coding

J Terminal 15 ON (no run-on when terminal 15 OFF)

J Battery management shut-off stage 0

J No undervoltage

J Overvoltage stage < stage 2

 

In measured value block 1, as the 2nd readout, the supply to the climate sensor heater can be checked.
