If the charge warning lamp ( ) on the instrument cluster comes on while driving, there is a
malfunction in the charge system including the battery. Therefore, carrying out the system check
is needed.
(4) Maintenance
Make sure that the battery cables are firmly connected.
If the terminals are corroded, clean them with a wire brush or sandpapers.
Always disconnect the battery cables with the ignition key removed. When disconnecting the
battery cables with the ignition key turned to ON or ACC position, several electric units can be
damaged due to sudden voltage change.
Check the battery for crack, damage or fluid leaks. Replace it if necessary.
Wipe out the battery fluid on the battery surface using a rubber glove and a clean cloth wetted
with soapy water. -

2. OVERVIEW
The functions of the immobilizer and the rechargeable key are controlled by the immobilizer &
rechargeable unit. Both functions are used in this system. This immobilizer & rechargeable unit
starts the engine by communicating with the engine control unit and increases the life of the
existing REKES battery by charging the battery of the remote control key.

3. FUNCTIONS OF IMMOBILIZER & RECHARGEABLE KEY
The functions of the immobilizer and rechargeable key are similar to that of the normal REKES
key. But, there are the immobilizer function that permits the engine to start only after confirming
the encrypted coding and battery charging function.
The followings are common functions of the normal REKES key and the immobilizer &
rechargeable key.
Door Unlock and Panic Function
Breifly press (below 0.5 sec): Door unlock and
　　　　　　　　　　　　 theft deterrent
mode deactivated
Press and hold (over 2 sec): Panic function
1. Door unlock (Briefly press)
If you send the door unlock signal using the
remote control key, with all the doors locked,
the door will be opened and the theft
deterrent mode will be deactivated. If the
door coupled switch of front room lamp is
pressed, the lamp will come on for 30
seconds. It will turn off immediately after the
lock button of the remote control is pressed.
2. Panic function: activated in the theft deterrent mode
When pressing the door UNLOCK and PANIC button for
approx. 2 seconds or longer, the warning alarm sounds
and the hazard warning lamp blinks for approx. 27
seconds.
The function is inactivated if any button of remote control
is pressed. ·
·
Breifly press (below 0.5 sec): Door lock and theft deterrent mode is activated
Press and hold (over 0.5 sec): Escort function
1. Door unlock (Briefly press)
Pressing this button locks all doors and activates the theft deterrent mode.
2. Escort function
If you press the button for more than 0.5 seconds in theft deterrent mode, the headlamp
comes on for about 20 seconds.
This function is deactivated if you press the door lock button of the remote control key. ·

4. START FUNCTION
1) Immobilizer Function
The immobilizer system prevents the vehicle theft by allowing only the authorized key to start the
engine. The transponder inside the key communicates with the immobilizer installed in the key
box, and the system permits the engine to start after confirming the encrypted coding from the
engine ECU.
For the vehicle with the immobilizer, there can be a problem in starting the vehicle or the
system error:Immobilizer & rechargeable
unit sends encrypted code
to transponder (2)
Sends an encrypted signal to
unit as a response (3) Randomly transmitted code is changed
to an encrypted signal in immobilizer &
rechargeable unit (4)
System compares signal from
transponder and encrypted signal in
immobilizer & rechargeable unit (5)
When two or more immobilizer keys come into contact with (each) other(s).
When the key is close to any device sending or receiving electromagnetic fields or waves
other than Ssangyong products.
When the key is close to any electronic or electric devices such as lighting equipment,
security keys or security cards.
When the key is close to a magnetic or metal object or a battery. a.

2) Rechargeable Key Function (Charging)
If the communication between ECU (engine control unit), immobilizer & rechargeable unit and
transponder is establisehd successfuly (engine started), the rechargeable Li-ion battery in the
transmitter is charged.
The charging is made by creating the mutual induced electromotive force in the antenna coil and
by supplying the charging current to the battery in the key. This charging is not resulted from the
direct contact but the induced electromotive force of the coil in the transmitter according to the
change of magnetic field. For details, see the below:
Primary magnetic
induction coil Secondary magnetic
induction coil
The single coil has both immobilizer
function and recharge function.
For the immobilizer function, if the
transponder confirms the key as the
startable key by communicating with the
ECU, it induces a magnetic induction in the
primary coil by passing through the current
with a certain frequency to the immobilizer
coil. The induced electromotive force
created in this way, is stored in the
chargeable battery through the commutator
and the circuit. Primary magnetic

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. -
