E. AIR QUALITY SYSTEM (AQS)
▶AQS operation
To change the AQS mode to Manual mode from AUTO mode, use the MODE switch o
r
the The AQS operates under air conditioner AUTO mode or when the AQS switch is
pressed under manual mode.It requires preheating time (for seconds) for operation and
the module and sensor are integrated. (However, it operates only when the DEF
(defroster) switch on the air conditioner switch panel is not pressed in.)
▶When driving out of polluted area
Remove the sensor and measure the resistance between terminal No. 5 and 6 on the
sensor connector. (standard: approx. 25°C, 2.2 kW)In addition, if the resistance
is extremely high or low, replace the sensor.
If the measured value is out of the specified range, replace the ambient temperature
sensor. If themeasured value is within the specified range, check as below.
Turn the ignition switch to ON position and measure the voltage to ambient
temperature sensor from theFATC controller connector. (standard: approx. 2 V at
25°C)
If the voltage value cannot be measured, check the circuit for open. If the measured
value is within thespecified range, replace the FATC controller.

▶AQS and air source selection switch
The AQS switch is integrated with the air source selection switch.
▶AUTO Mod
The air source is not changed when pressing the AQS and air source selection switch in
“AUTO” mode. However,the indicator on the switch turned ON/OFF. In other words,
the air source cannot be changed to recirculationmode in AUTO mode by just pressing the
switch.To change the air source to recirculation mode in AUTO mode, get into Manual
mode first, then press the airsource selection switch.
▶Manual Mode
To change the AQS mode to Manual mode from AUTO mode, use the MODE switch o
r
the fan speed controldial. In Manual mode, the “AUTO” symbol on the display is
disappeared. When pressing the AQS and air sourceselection switch, the mode is
changed in order of AQS LED ON, AQS LED OFF (fresh air), and air source LEDON
(recirculation). The figure shows that the mode has been changed to the recirculation
mode from fresh air mode under AQSmode (AQS LED ON) after detecting the polluted
outside air.
Self diagnosis and preheating process during initial operation of A/C controlle
r
(AUTO mode)
-
When the air conditioner controller is operated in AUTO mode during its initial
operation, the air sourceis changed to the recirculation mode and AQS LED comes
on.(This is the self diagnosis and preheating process for AQS.)
After completing the above process, the AQS LED is turned off and the air source is
automaticallychanged to the fresh air mode.

▶Components of AQS
Air Quality System (AQS) changes the air source selection to recirculation mode when
polluted air is detectedthrough AQS sensor. The air source selection returns back to fresh
air intake mode after a specified period orthe polluted air is disappeared.
▶AQS operation (AQS switch is pressed in): detecting the polluted outside air
When pressing the AQS switch, the LED on the AQS switch is turned on and the
A
QS
function is activated.
When the polluted outside air is detected, the AQS operates and converts the ai
r
source to recirculationmode automatically. At this moment, the recirculation mode
indicator comes on in the display.

F. AQS OPERATION CIRCUIT
▶Ambient temperature sensor
If the polluted air is disappeared, the air source is automatically changed to the fresh
air mode and AQSLED stays on.
The air source is not changed when pressing the AQS and air source selection switch
in “AUTO” mode. To change the air source to recirculation mode in
A
UTO
mode, get into Manual mode first, then pressthe air source selection switch.

Measure the voltage value of AQS. (between connector terminal No. 3 and 4.)
If the measured voltage is out of 0.1 to 4.8 V, replace the AQS.
If the measured voltage is out of the specified range, replace the AQS. If it is within
the specified range, check as below.
Turn the ignition key to “ON” position.
Measure the voltage between terminal B9 and B15 on the air conditioner controller.
If the voltage value cannot be measured, check the circuit for open. If the measured
value is within thespecified range, replace the FATC controller.
