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.

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.
