This controller is equipped with a failure system monitor. When any failure to
the air system occurs, the display will show a message according to the table
below:
Pressure Switch failure
Temperature sensor open
Temperature sensor in shock
Alternator failure
FAILURE
DESCRIPTION
1) If any failures occurs to the Pressure Switch, the display will show the
message (HÁ) and the system will shut the compressor off. The system will
wait for 3 minutes to turn the compressor on again, once the failure is
corrected.
2) As the system operates according to the internal temperature, the
controller possesses two failure codes to monitor the temperature sensor:
a) If the temperature sensor is open, the display will show (OP)
b) If the temperature sensor is in shock, the display will show (SC)
3) This controller possesses a parameter to monitor the alternator. In case of
failure or in case the alternator is not recharging, the display will show (AL).
Important:
Whenever a failure to the air conditioner system is identified, the
vehicle must be sent to a Spheros authorized service station.
