1. OVERVIEW
The SKM (Smart Key Module) system is equipped to only the vehicles with smart key and is to prevent
theft and enhance the driver experience. When the driver presses a door handle switch carrying a smart
key, this system checks the smart key information and driver door status and locks/unlocks the doors
(passive function). The vehicle can be started when the driver enters the vehicle and presses the
START/STOP switch (passive start function).

(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. for up to 10
seconds. 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/STOP 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 seconds.
When the ignition status is changed by the transponder verification while the smart key status is sent
through the B-CAN, the SKM sends the smart key verification signal and also sends the transponder
verification signal for 10 seconds. -
-
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 B-CAN 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 B-CAN for up to 10 seconds until
the warning condition is deactivated.
The SKM sends the transponder verification warning when the verification has failed with the smart
key inserted into the immobilizer holder. -
Transponder verification fail detection and transmission conditions
When the ignition status is changed after the transponder is verified by the START/STOP switch ON
input, the SKM sends the transponder verification status for 10 sec. -

(10) Brake not working alert
The SKM sends the brake not working alert signal for 10 sec. every time the ignition status is changed
after the 1st cycle (OFF-ACC-IGN-ACC-OFF)
while the brake is not operated.
when the brake pedal is depressed, the system is reset and alert deactivation signal is sent.

(11) Smart key slot detection alert
The SKM sends the smart key slot detection alert signal for 10 sec. when a smart key inserted into
the slot is detected with IGN OFF and the driver's door open. -

12. SKM IMMOBILIZER SYSTEM
1) System Description
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 SKM (immobilizer slot) and EMS (ECU) through
P-CAN communication, and the system permits the engine to start after confirming the encrypted
coding.
When the START/STOP switch is pressed with the smart key inserted into the immobilizer slot because
of the smart key battery discharge, the SKM communicates with the EMS (ECU) through P-CAN, and
the ECU starts to control the engine only the signal is valid.
A valid key verification time is provided for 10 seconds and the engine can be started during this time. If
pressing the START/STOP switch again after this 10 seconds, the key verification process is performed
again.

Door lock/unlock control by door LOCK switch
When moving the driver or passenger door lock (knob) switch to LOCK from UNLOCK position, BCM
sends the LOCK signal for 0.5 seconds.
When moving the driver or passenger door lock (knob) switch to UNLOCK from LOCK position, BCM
sends the UNLOCK signal for 0.5 seconds.
The LOCK (UNLOCK) operation by the door lock (knob) switch is not available when sending the
LOCK (UNLOCK) signal by any other method such as remote control key.
When reconnecting the battery, the door lock (knob) switch is not operational regardless of the door
lock switch positions.
All doors stay unlocked when receiving the door lock signal in 0.5 seconds after closing the doors. 1.

The UNLOCK by the air bag deployment signal takes priority over the LOCK/UNLOCK control from
other functions.
The LOCK/UNLOCK requests from other functions during or after the UNLOCK output by the air
bag signal are ignored. However, the LOCK control is carried out when the ignition switch is turned
to the "OFF" position.
The same request during the LOCK/UNLOCK output is ignored. However, the UNLOCK by the air
bag deployment signal or operation by the smart key is carried out.

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. -
