Intake sensor
It is mounted to the side of
evaporator core and detects the
temperature of the evaporator
core.Water temperature
sensor
It is mounted to the heater pipe
part and detects the coolant
temperature.
3) Air Conditioner Module Layout
Temp actuator
It changes the air mix door
opening according to the
control command from the
heater and A/C control
assembly.Evaporator core
It cools the surrounding air by
passing through the low-
temperature and low-pressure
refrigerant sprayed from the
expansion valve.
Heater core
It is mounted to the left-hand of
the air conditioner module and
heats the indoor using the heat
of the engine coolant.
Mode actuator
It controls the air outlet damper
to the five directions according
to the control command from
the heater and A/C control
assembly.

Blower motor
It is mounted to the bottom of
the blower box and sends the
air inside of the vehicle. PTC heater
It is mounted to the heater air
outlet in the heater module
and warms the air from the
heater to the air vent.
Intake actuator
It changes the air source selection
mode according to the control
command from the heater and A/C
control assembly.A/C filter
It is mounted to the top of the
blower motor and filters the air
before it is discharged through
the duct.
MOS module
It controls the rotation speed of
the blower motor by receiving the
fan speed control signal from the
heater and A/C control assembly.

(2) Temperature control
The blowing air temperature is controlled by the temp actuator and the set temperature can be checked
via the LCD display.
Manual control
The discharge air temperature is controlled by the temperature control dial. The driver can select one
of the 31 levels.
Auto control
When pressing the AUTO switch, "AUTO" is shown on the display and the fan speed and air distribution
mode are adjusted automatically to keep interior temperature to the set temperature. In full AUTO mode,
the FATC receives various signals such as the indoor temperature, ambient temperature, engine coolant
temperature, sunlight, from different sensors to control the A/C compressor, mode actuator, intake
actuator, temp actuator, blower motors, etc. to keep indoor environments fresh.
Max. cooling/heating control (AUTO mode)
If the temperature is set to the lowest level (Lo) or highest level (Hi), the system will go into the maximum
cooling or maximum heating mode regardless of the sensor signals.

(4) Air source control
The air source selection is made by the intake actuator. The driver can see the air source mode through
the switch's indicator and the LCD display.
Manual control
Press the air source selection switch to control the air source selection door manually. The air source
mode is switched
between the fresh air and recirculation alternatively each time the switch is pressed.
Auto control
In auto mode, the basic setting for the air source is fresh air. When the ambient temperature is high
during cooling,
the air source is changed from fresh air to recirculation to lower the temperature.
Control by vehicle speed (heating)
The air source selection is controlled in accordance with the vehicle speed while driving. Operating
conditions and control process are as follows:
AUTO mode
When the vehicle speed is 45 km/h or lower in fresh air mode, the air source door is open 30% of its
maximum opening. If the vehicle speed is 65 km/h or more, then
the air source door is completely open. -

and the electric fan 7.5V or higher.

(7) Self-diagnosis
Diagnostic trouble code
The FATC has a self-diagnosis function that can diagnose the system by itself. If this system is
defective, the LCD display shows the diagnostic trouble code (DTC) to inform a driver of defects on the
device such as a sensor or actuator. The driver can see the each sensor data on the air conditioning
system after entering self-diagnosis mode. Before checking each component, be sure to check the
default code by using self diagnosis function.
The diagnostic trouble code (DTC)
flashes twice and is displayed
repeatedly in order as long as a
separate operation is not performed.

(4) Air source control
When pressing the air source selection switch, the air source mode is changed via the intake actuator's
operation. The air source mode is switched between the fresh air and recirculation alternatively each
time the switch is pressed. You can see the air source mode through the switch's indicator. (the indicator
comes on at recirculation mode)
Control by vehicle speed
The air source selection is controlled in accordance with the vehicle speed while driving. Operating
conditions and control process are as follows:
When the PTC heater operates at fresh air mode in winter
When the vehicle speed is 45 km/h or lower in fresh air mode, the air source door is open 30% of its
maximum opening. If the vehicle speed is 65 km/h or more, then the air source door is completely
open. -
-
However, the electronic fan should be more than 7.5 V.

(6) A/C control
The air conditioner is operated at the defroster mode and MAX air conditioner mode and when the A/C
switch is turned to "ON" position. It is controlled by the A/C compressor of the engine ECU according to
the signal from the heater and A/C control assembly. The driver can see that the A/C has been activated
when an indicator lamps at the A/C switch and MAX A/C switch comes on. If the intake sensor detects
the freezing of the evaporator core, it stops the air conditioner by turning off the compressor.
MAX A/C control
This is designed for increasing driver comfort. When the switch is pressed, the air conditioner is
operated and vent and recirculation modes are selected automatically. The discharge temperature and
fan speed are regulated depending on the driver's choice.
