(3) CIRCUIT DESCRIPTION
A. THE V5 FULL AUTOMATIC TEMPERATURE CONTROL (FATC) SYSTEM
The full automatic temperature control (FATC) uses the integrated control panel as the
driver’s interface to thesystem.
The FATC receives driver’s input signal and various input signal from sensors and
controls the actuatorsto maintain driver’s desired room temperature.
B. SELF DIAGNOSIS (ONLY FOR FATC AIR CONDITIONER)
Self Diagnosis Code
▶
The FATC controller has self diagnosis function that can diagnose the system by itself.
Before checking eachcomponent, be sure to check the default code by using self diagnosis
function.

press the OFF switch 3 times within 3 seconds after temperature setting while the
AUTO switch is pressed.
The Micro computer integrated in controller displays the defect codes in turns on the
VFD after performing self diagnosis. Below figure shows the defect code caused by
disconnecting the interior temperaturesensor/humidity temperature sensor connector.
After displaying defect code, operates again in AUTO mode.

C. SYSTEM DIAGRAM
Air Conditioner Compressor Control by Engine ECU
▶
In case of current vehicle models, the system turns ON/OFF the compressor switch
according to refrigerant pressure, ambient temperature and condenser temperature to
protect air conditioner circuits. However, for the vehicle equipped with DI engine, the
engine ECU turns off air conditioner compressor as below in addition to above conditions.
Coolant temperature: below -20°C
Coolant temperature: over 115°C
For approx. 4 seconds after starting the engine
When engine speed is below 650 rpm
When engine speed is over 4,500 rpm
During abrupt acceleration for the vehicle equipped with manual transmission
