6810-00
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.

temperature.
AUTO switch
When pressing this 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.
ON/OFF switch
Pressing the switch turns the FATC on/off. When
the FATC is turned on, it memorizes the previous
status before becoming off.
Defroster mode switch
This is used to remove the condensation from the
windshield. When you press the switch, the
indicator comes on and the air distribution is
changed to the windshield at the same time, then
the air conditioner starts to operate. When you
press the switch again, the indicator goes off and
the air distribution returns to the previous status.

Indoor temperature sensing part
The incar sensor is mounted to the rear of the
FATC and detects the interior air temperature
drawn through the air inlet.
Air source selection switch
When the switch is pressed, the indicator comes
on and the mode is switched to the recirculation
mode at the same time. When pressed again, the
indicator goes out and switched to the fresh air
mode at the same time.
Fan speed dial
Turn the dial to the left or right to adjust the fan
speed in 8 steps and the fan speed can be
checked through the LCD display.
A/C switch
When the switch is pressed, the indicator comes
on and the air conditioner starts at the same time.

(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.

(6) A/C control
The air conditioner 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 the air conditioner operation through the LCD
display and the indicator of the A/C switch.
Manual control
Pressing the A/C switch or selecting defrost mode turns on the A/C.
Auto control
The A/C is controlled in accordance with the indoor temperature and ambient temperature.
or below) in winter, the compressor is turned off to protect the A/C compressor.

(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.
