2) DUMP (ESP is working) Mode
The pressure decreases just before the wheel speed drops and the wheels are locked.
The inlet valve closes and the outlet valve opens as in the ABS HECU and the oil is gathered at the low
pressure chamber while no additional oil is being supplied. Then the pump operates to allow fast oil
drainage. The shuttle valve and the separation valve do not operate while decompression.

11-26
4) RISE (ESP is working) Mode
The shuttle valve and inlet valve will be open and the separation valve and outlet valve will be closed.
Then, the pump is operated. When ESP operates while the ABS is operating, the pressure will be
increased continuously until just before the corresponding wheel gets locked.

5) Hydraulic Circuit of HBA
The above figure shows one front and one rear wheel and the same hydraulic circuit forms as in the
ESP operation. When HECU recognizes that it is an emergency and it is required for hard braking,
depending on the pressure value of the brake pressure sensor and pressure changes caused by the
pressure sensor timing, it operates the pump immediately to apply the brake pressure at the wheels.
Then, the pressure in the pump increases until just before the corresponding wheel gets locked. The
motor still keeps rotating and the outlet valve and the separation valve will stay closed. When the wheel
starts to lock, the HBA function cancels and switches to ABS operation.

Preload is the term used in mechanical engineering to describe the load applied to a fastener merely as
a result of being fastened (and before any external loads are applied)
5. INSPECTION AND MAINTENANCE
Place the wheels at straight ahead direction.
Lift up the vehicle with a lift.
Unscrew the adjusting plug lock nut.
Measure the torque of the adjusting plug. 1.

If the torque is excessive or too low, adjust to
the specified torque. 5.
Place the rack gear to the center position.
Tighten the adjusting plug to 10.2 Nm.
Turn the pinion gear so that the rack gear is
turned to lock to lock 5 times.
Unscrew the adjusting plug.
Tighten the adjusting plug to 4.6 to 5.6 Nm.
Unscrew the adjusting plug to 67.5°. -

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.
