1. CAUTIONS FOR AIR BAG OPERATION
When there is any deployed air bag (including seat belt pretensioner), the air bag unit should
be replaced. Any DTC (Diagnostic Trouble Code) in the air bag unit should not be cleared
since the unit has data for status when the air bag was deployed as well as information
related to the air bag deployment.
Note that the used components related to the air bag, especially the air bag unit, should be
packaged in an air tight container to prevent any damage.
Do not connect a tester to any connector or component to check supply voltage or
resistance of air bag related components. The detonator may explode due to a sudden extra
power supplied by the tester.
Before removing or installing any air bag related components, disconnect the negative battery
cable. 1.

Collision sensors, a kind of impact G (acceleration) sensor, detect the lateral and longitudinal
collisions and determine whether or not to deploy air bags. The roles of each collision sensor are
as follows:
Front G sensors (inside the air bag unit)
Send signals to the front air bags (driver and passenger air bags) and the driver's and front
passenger's seat belt pretensioners. When the front collision G sensor sends out only the air
bag deployment signal, the signal deploys the two front air bags and activates their seat belt
pretensioners.
Once an air bag deploys, its repair parts vary according to the deployment situation and damage
to the vehicle from collision. Needed repairs also slightly vary between the front air bags and the
curtain air bags. The following are the differences:
Replacement parts when the front air bags deploy:
Air bag unit and its wiring (including connector), seat belt pretensioner and its wiring
(including connector), whole front air bags, instrument panel (IP)

2. OPERATING RANGE
In the event of the collision, the air bag will be deployed when the G value detected by the G
sensor in the SDM is beyond the impact limit. ▶
Seat Belt Status Air Bag OperationSeat Belt Pretensioner Operation
Fastened Over reference speed Below reference speed
Unfastened Below reference speed Inoperative
Failure, during initial
diagnosisBelow reference speed Below reference speed
No sensor Below reference speed Below reference speed
This is based on frontal collision and reference speed is between approx. 4 and 24 km/h. *
The air bag is deployed in the event of frontal collisions while drving.
But, there are exceptional cases as follows: ▶
Situation Condition
May operate or not
Never operate
Seldom oeprate
Underbody impact from the road surface, impact against the
curb at a very high speed, or dropping impact onto the road
surface with a large angle occurs.
The vehicle rolls over or tips over sideward by severe impact. -
-
A collision with oblique impact to the front seat direction or a front
collision to the diagonal direction occurs.
A front/rear collision occurs.
The vehicle rolls over or tips over sideward with minor impact.
The air bag warning lamp is on. -

-
-The vehicle is stationary or a front collision occurs with low speed.
A rear collision occurs.

1. OVERVIEW
Collision sensors, a kind of impact G (acceleration) sensor, detect the lateral and longitudinal
collisions and determine whether or not to deploy air bags. The roles of each collision sensor are
as follows:
Front G sensors (inside the air bag unit))
Send signals to the front air bags (driver and passenger air bags) and the driver's and front
passenger's seat belt pretensioners. When the front collision G sensor sends out only the air
bag deployment signal, the signal deploys the two front air bags and activates their seat belt
pretensioners.
Once an air bag deploys, its repair parts vary according to the deployment situation and damage
to the vehicle from collision. Needed repairs also slightly vary between the front air bags and the
curtain air bags. The following are the differences:
Replacement parts when the front air bags deploy:
Air bag unit and its wiring (including connector), seat belt pretensioner and its wiring
(including connector), whole front air bags, instrument panel (for vehicle with passenger air
bag)
For the air bag system in KORANDO SPORTS, the seat belt pretensioners on both sides as well
as the driver/passenter air bags are deplyed when the front air bag is deployed like as they did.

Passenger Air Bag

Passenger pretensioner
Air Bag Unit (SDM)
The collision G sensor is installed
inside this. And it sends out signals to
deploy the front air bags (driver and
passenger air bags) and/or the driver
and passenger seat belt retensioners.
When the front collision G sensor
sends out only the air bag deployment
signal, the signal deploys the two front
air bags and activates their seat belt
pretensioners.

4. DEPLOYMENT
According to the collision deceleration rate that each collision G sensor reads, the air bag unit
sends out about 2~4 or higher Amp current. This current generates some heat, which fires the
detonator in the inflator.
The table shows the basic inner resistance of the air bag related module and the basic instant
current necessary for firing.
1) Air Bag System Deployment (Firing Loop)
2) Air Bag Deployment Signal Output (Crash Out)
When the air bag deploys, the signal is sent to STICS to perform the basic security operation
which is the automatic door unlock function that release the automatic door lock mode.
Deployment signal
output (crash out)200ms
Automatic Door Unlock (Crash unlock: unlock when colliding) ▶
The air bag collision signal input cannot be accepted within 7 seconds after turning the ignition
key to "ON" position.
After this period, the door lock system outputs "UNLOCK" for all doors for 5 seconds from 40
ms after receiving the air bag collision signal.
Even though the key is turned to "OFF" position during the output of "UNLOCK", the output
continues on for remaining period.
The function is erased when turning "OFF" the ignition switch. 1.

Please do not connect a tester to any air bag connector or single item to measure the
supplied power or resistance. The detonator may explode due to a sudden extra power
supplied by the tester.
Before removing or installing any air bag related components, disconnect the negative
battery cable. -
