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.

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.

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.
