3) Operation of Immobilizer
When the ignition switch is turned to the ON position with REKES key, the BCM checks the crypto code
of the inserted key using the immobilizer antenna and sends whether the engine is startable or not to the
engine ECU through the CAN communication so that the engine can be started.

REKES key
Immobilizer antenna
ECUCAN line
For the vehicle with the immobilizer, there can be a problem in starting the vehicle or the system error:
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. -

(2) Ignition status change
The ignition status is changed to OFF, ACC ON, IGN ON and engine cranking by one START/STOP
button.
The SKM cuts the power for IGN2 and ACC relays while the engine is cranking as cutting the electric
load is necessary.
The SKM monitors the brake pedal status through the hardware signals.
The ignition status change is available when the engine START/STOP button is pressed.
The SKM uses the EMS (engine condition) and ABS/ESP (FR vehicle speed) signals sent through the
P-CAN bus (High Speed CAN).
When the smart key battery is discharged and the driver inserts the smart key into the immobilizer slot
in emergency mode, the smart key verification is performed if the brake or START switch is pressed
before the ignition status is changed (ACC ON, IGN ON).

When the engine START/STOP switch is pressed for 3 sec. or more at more than 3 km/h, the
ignition status is changed from IGN to ACC.
If the engine START/STOP switch is pressed again, the ignition status is changed from ACC to
IGN.
The 4 vehicle speeds are abnormal (CAN signal timeout, abnormal signal):
If the engine START/STOP switch is pressed for 3 sec., the ignition status is changed from IGN
to ACC. If the switch is pressed again, the ignition status is changed from ACC to OFF (DTC
set). -

(4) Smart key battery discharge warning (3) Smart key verification fail warning
When the verification is requested for ignition status change or engine starting and no verified smart key
is in the vehicle, the SKM sends the [smart key verification status] signal, which indicates that the
verification has failed, for up to 10 sec. until the verification fail conditions are deactivated.
Verification fail detection and transmission conditions ▶
When the ignition status is changed after a smart key is verified by the START switch ON input, the
SKM sends the verification status for 10 sec. -Normally, the smart key verification warning is one of the smart key fail conditions. -
Ignition status change
(OFF ->ACC) / (OFF ->IGN)/(ACC ->IGN) / (IGN -> engine ON) *
If above conditions are met again, the SKM re-verifies a smart key and sends the verification status for
another 10 sec.

through the BCAN, the SKM sends the smart key verification signal and also sends the transponder
verification signal for 10 sec. -
-
If low smart key battery is detected during the verification process for ignition status change or engine
start, the SKM sends the signal for [smart key battery low voltage warning] to the BCM and instrument
cluster through the BCAN for up to 10 sec. until the warning condition is deactivated.
Smart key battery discharge confirmation and deactivation ▶
If the smart key battery low voltage is confirmed, the SKM sends the smart key battery low voltage
warning signal.
If the smart key battery is in normal condition, the SKM sends the smart key battery low voltage
warning deactivation signal.
The smart key is the last used key. -

(5) Transponder verification fail warning
If a verified smart key is not found by the key verification process, the SKM sends the information that
indicates the key is not verified to the instrument cluster through the BCAN for up to 10 sec. until the
verification fail condition is deactivated.
The SKM sends the transponder verification warning when the verification has failed with the smart key
inserted into the immobilizer holder. -

3. SUNROOF OPEN WARNING
1) Warning Sound
When removing the key and then opening the door with the sunroof open, the warning sound is heard.
Closing the door stops the warning sound.
2) Message on Instrument Cluster
The following message is displayed on the screen in the instrument cluster.
General precaution for sunroof
Even though the sunroof can be operated when the engine is not running, operating the sunroo
f
repeatedly with the engine turned off will run down the battery. Operate the sunroof while the
engine is running.
When the sunroof operation is completed, release the switch. Keeping pressing the switch can
result in malfunction.
Especially in winter, never operate the sunroof if operation areas are iced. Wait until melted.
Make sure that the sunroof is completely closed when leaving the vehicle. Leaving the vehicle with
the sunroof open result in a theft. In addition, rain or snow can get into the vehicle through the
open sunroof.
When the sunroof is fully open, wind buffeting symptom can be worse. In this case, try to adjust
the sunroof position manually or open the sunroof into 1st first step until the wind buffeting is
disappeared.
Parts of the body can be trapped in the sunroof and can be struck by passing objects. Do not stick
hands, head or anything else out of the openings.
Remove any dirt and foreign material stuck on the edge of the sunroof glass periodically.
Noise can occur due to friction when operating the sunroof. -
