 Passenger Air Bag   
Upper side Lower side
 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.

3. OPERATION PROCESS
The overall air bag operation  process  and its functions  and roles are broadly  explained  in this 
block diagram. This diagram summarizes and highlights  the functions  adopted  by Ssangyoung 
Motors.

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.

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. -

The "Unlock" control by air bag signal prevails over any "LOCK" or "UNLOCK" control by other 
functions.
The "LOCK/UNLOCK" request by other functions will be ignored after/during the output of 
"UNLOCK" by the air bag.
However, the door lock is controlled by other functions when the ignition switch is "OFF".
"LOCK" (or "UNLOCK") output is ignored if "LOCK" (or "UNLOCK") output is required while 
performing the output of "LOCK" (or "UNLOCK").
However, UNLOCK by air bag signal and operation by the remote control key are valid.
If the door lock system outputs "LOCK" and "UNLOCK" simultaneously, only the "LOCK" 
output can be activated. 1.

5. AIR BAG WARNING LAMP OPERATIONAL CONDITIONS
The air bag warning lamp on the instrument panel has a few operational conditions. The following 
are the conditions:
When Turning the Ignition Switch to ON Position Initially ▶
The air bag unit performs a turn-on test when the ignition is turned on initially. The air bag unit 
flashes the air bag warning lamp 6 times at 1 Hz interval. After that, the air bag warning lamp will 
go off if no malfunction have been detected.
When the Air Bag Unit Detects Any Malfunctions in Unit ▶
When the Air Bag Unit Detects Any Intermittent Failure ▶ When it is recorded as a system failure in the air bag unit, the air bag warning lamp on the 
instrument panel comes on for about 6 seconds and goes off for 1 second. Then the waning 
lamp stays on.
When, due to an error from outside the system, the intermittent failure signal is received 5 times or 
less, the air bag warning lamp comes on for about 6 seconds and then, goes off.
