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   Compressor off (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 (because of a request from the engine control unit, via data bus.)

 13   Compressor off (because of a faulty signal from refrigerant pressure and temperature sender

        -G395.)

 14   Compressor off (because of a fault in the 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 the ambient temperature, possibly both

ambient temperature sensors -G17 and fresh air intake duct temperature sensor -G89

        defective.)

 19   Compressor off (-Climatronic control unit -J255       

        was switched on via the "auxiliary heater" function.)

    20   Compressor off (readout currently not used.)

 21   Compressor off (measured ambient temperature was below -8°C and is still below

-5°C, there is no request for automatic recirculated air mode or the measured ambient temperature

        was below +2°C and is still below +5°C and the "automatic recirculated air mode" function is not

        active.)

 22    Compressor off (measured passenger compartment temperature is below 8°C. The measured         

        ambient temperature was below -8°C and is still below -5°C. There is a  request

        recirculated air mode).

 23   Compressor off (via the data bus system a fault message for activation of the

radiator fans was sent,  e.g. by the relevant engine control unit, and received by the

       Climatronic control unit -J255.)

 24   Compressor off (readout currently vacant.)

 25   Compressor off (readout currently vacant.)
