Breakdown of compressor shut-off conditions
0 Compressor on (no shut-off condition detected.)
1 Compressor off (pressure in refrigerant circuit was or is too high.)
2 Compressoroff (basic setting not performed or not performed without error.)
3 Compressor off (pressure in refrigerant circuit is too low.)
4 Compressor off (engine nor running or has been running for less than 2 sec.)
5 Compressor off (engine speed is below 300/ min.)
6 Compressor off (compressor switched off by ECON118°C.)

12 Compressor off (request from the engine control unit, via data bus.)

13 Compressor off (faulty signal from refrigerant pressure and temperature sender
-G395.)
14 Compressor off (fault in data bus system.)
15 Compressor off (the pressure in the refrigerant circuit in this driving period was at least 30 times too
high.)
16 Compressor off (the measured temperature downstream of the evaporator has for over a minute been below
0°C.)
17 Compressor off (measured temperature downstream of evaporator below -5°C.)
18 Compressor off (there is no valid measured value for theambient temperature, possibly both
ambient temperature sensors -G17 and fresh air blower intake duct -G89 defective.)
19 Compressor off (-Climatronic control unit -J255
was switched on via the "auxiliary heater" function.)
20 Compressor off (readout currently vacant)
21 Compressor off (measured ambient temperature wasbelow -8°C and is still below
-5°C, there is no request for automatic recirculated air mode or the measuredambient temperature
was below +2°C and is still below +5°Cand the "automatic recirculated air mode" function is not
active.)
22 Compressor off (measured passenger compartment temperature below +8°C. The measured
ambient temperaturewas below -8°C and isstill below -5°C. Arequest for
recirculated air mode has been received.)
23 Compressor off (via the data bus system a fault message for activation of the
radiator fans was sent, e.g. by therelevant engine control unit,and received bythe
Climatronic control unit -J255.)
24 Compressor off (readout currently not used.)
25 Compressor off (readout currently not used.)
