5. AIR QUALITY SYSTEM (AQS)
1) Components of AQS
Air Quality System (AQS) changes the air source selection to recirculation mode when polluted
air is detected through AQS sensor. The air source selection returns back to fresh air intake
mode after a specified period or the polluted air is disappeared.

AQS and air source selection switch
The AQS switch is integrated with the air source selection switch.
AUTO Mode
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 recirculation mode 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 air source selection switch.
Manual Mode
To change the AQS mode to Manual mode from AUTO mode,
use the MODE switch or the fan speed control dial. In Manual
mode, the “AUTO” symbol on the display is disappeared.
When pressing the AQS and air source selection switch, the
mode is changed in order of AQS LED ON, AQS LED OFF
(fresh air), and air source LED ON (recirculation).
The figure shows that the mode has been changed to the
recirculation mode from fresh air mode under AQS mode (AQS
LED ON) after detecting the polluted outside air.

2) AQS Operation
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 ai
r
conditioner switch panel is not pressed in.)
Self diagnosis and preheating process during initial operation of A/C controller
(AUTO mode)
1.
AQS operation (AQS switch is pressed in): detecting the polluted outside air
2.
When the air conditioner controller is operated
in AUTO mode during its initial operation, the
air source is changed to the recirculation
mode and AQS LED comes on.
(This is the self diagnosis and preheating
process for AQS.)
1.
After completing the above process, the
AQS
LED is turned off and the air source is
automatically changed to the fresh air mode.
2.
If the AQS switch is pressed in, the AQS
function works regardless of air conditioner
controller operation.
When pressing the AQS switch, the LED on
the AQS switch is turned on and the
AQS
function is activated.
When the polluted outside air is detected, the
AQS operates and converts the air source to
recirculation mode automatically. At this
moment, the recirculation mode indicato
r
comes on in the display.

4) Inflator
The inflator is a type of the direct gas generated device.
The inflator with initial low pressure provides negative restraint effect regarding passengers
moving and time.
On the contrary, the inflator with initial high pressure allows other components of the airbag
to make a excessive impact resulting in any personal injury.
Thus, the inflator output must be optimized according to the characteristic of the vehicle and
passenger moving.
The discharge gas has no toxicity or inflammability and also it is the important parameter to
control the high temperature for gas firing. ·

5) SDM (Sensing and Diagnostic Module)
The airbag system consists of the module section (driver, passenger and side), seat belt
section and SDM.
The SDM has no user-serviceable parts and monitors the system components continuously.
The SDM also records any faults which are discovered.
The SDM allows the fault codes to be retrieved with a scan tool and illuminates a warning
lamp that alerts the driver to any faults. 1.
2.
3.
The SDM located on floor beneath the floor console assembly. The SDM performs the
following functions:
Impact decision processor function.
Determine the airbag deployment through the impact signal of the accelerometer sensor and
the safety sensor. ·
·
Malfunction detection and recording any faults that are detected.
Monitor the supplemental restrain system electrical components and set a diagnostic trouble
code when malfunction is detected.
Display airbag fault codes Display airbag fault codes and system status information when
connected to a scan tool.
Self-diagnosis function Illuminate the AIRBAG indicator to alert the driver to any fault.
Power supply function Provide a reserve power source to deploy the airbags and
pretensioners if an accident has disabled the normal power source. ·
