SsangYong Korando III (2010 year). Manual - part 162

04-12

The system first identifies the last smart key used, and then identifies all the other registered smart 

keys until a normal smart key is verified.

The system identifies the smart keys by using the outside door handle antenna on the door handle 

switch which has sent the signal.

Smart key search input: The last door is opened and then closed. Outside door handle switch, Brake 

switch, START switch (Tailgate open request)

Searching for other keys

▶

When the ignition status is IGN ON or ACC ON, the SKM starts to verify the smart key if any door is 

opened and then closed. If one or more smart keys are verified as being in the vehicle, the smart key 

verification procedure is stopped. If no verified smart key is identified as being in the vehicle, the SKM 

sends the signal which identifies that there is no verified key inside the vehicle to the BCM and instrument 

cluster through the BCAN (Smart key not identified warning).

Interruption of door LOCK & Smart key function by outside door handle switch

▶

When the door LOCK signal is received from the driver/passenger door handle switch with the ignition 

status OFF or ACC ON, the SKM identifies the verified smart key and sends the passive LOCK signal 

to the BCM through the BCAN if the ignition is turned to OFF.

The SKM receives the theft deterrent mode information signal from the BCM through the BCAN.

If there is any verified smart key in the vehicle, the function of the verified smart key is interrupted.

(3) Passive UNLOCK

When the system searches for a smart key by the input from the outside door handle switch, the SKM 

sends the passive UNLOCK signal to the BCM if all the doors are closed and a normal smart key is 

found outside the vehicle.

Passive UNLOCK hardware control

▶

The SKM sends the door LOCK/UNLOCK signal to the BCM through the BCAN network when a 

smart key is verified after the signal from the driver/passenger outside door handle switch is received 

through the hardware.

Passive UNLOCK by outside door handle switch

▶

When the ignition status is OFF, ACC ON or IGN ON, the SKM starts to verify the smart key if below 

conditions are met.

When the driver or passenger door handle switch is operated, the SKM verifies if a smart key is outside 

the vehicle using the corresponding antenna.

When the outside door handle switch is operated, the SKM verifies if a smart key is outside the 

vehicle using the corresponding exterior antenna.

The SKM sends the signal for [Passive UNLOCK command] to the BCM through the BCAN if a 

smart key is identified as being outside the vehicle.

If no smart key is identified as being outside the vehicle, this process is stopped and restarted when 

the next signal is received from the outside door handle switch.

When the driver's door is locked with the ignition status ACC ON or IGN ON, the SKM sends the 

signal for [Passive UNLOCK command] to the BCM through the BCAN to unlock the door without 

changing the ignition status to OFF.

Exceptional mode

When operating the door handle switch, the system changes the smart key searching conditions in 

vehicle inside and outside according to the theft deterrent mode.

- Searching sequence when disarmed by BCM: Inside > Outside

- which function is restricted when the BCM is in theft deterrent mode.

(4) Passive tailgate open

When a normal smart key is found by the signal from the tailgate open switch, the system sends the 

tailgate open control signal to the BCM.

Passive tailgate open hardware input/output control

▶

The SKM receives the tailgate open switch signal from the BCM through the BCAN communication.

The SKM sends the tailgate open output signal to the BCM through the BCAN communication.

Tailgate open switch control

▶

Tailgate closed -> open

When the ignition status is OFF, ACC ON or IGN ON, the SKM starts to verify the smart key in the 

tailgate open actuation area after receiving the tailgate open signal for [tailgate open request] from the 

BCM through the BCAN.

The SKM sends the signal for [Passive tailgate open] to the BCM through the BCAN to open the 

tailgate and deactivate the theft deterrent mode if a smart key is identified as being outside the vehicle.

If no smart key is identified as being outside the vehicle, this process is stopped and restarted when 

the next tailgate open request signal is received.

Smart key search mode

▶

The system first identifies the last smart key used, and then identifies all the other registered smart 

keys until a normal smart key is verified.

If the tailgate antenna identifies a normal smart key, the system searches for a smart key in inside 

area of the tailgate and inside the vehicle.

The tailgate is opened only when a valid smart key is found within the tailgate antenna range, and the 

tailgate is not operated by a smart key in inside area of the tailgate.

Smart key search input: The last door is opened and then closed. Outside door handle switch, Brake 

switch, START switch (Tailgate open request)

Tailgate open -> closed

When the tailgate is closed with all the other doors are closed, the SKM sends the signal for [smart 

key inside the vehicle] through the BCAN if there is a verified smart key inside the vehicle.

When the tailgate is opened and then closed in theft deterrent mode, the signals for [external buzzer] 

and [smart key detect warning] are sent for 10 sec. through the BCAN if there is a verified smart key 

inside the vehicle.

(5) Puddle (approach) lamp control

Operating condition

▶

When the driver approaches the vehicle in theft deterrent mode (within 1 m), the SKM sends the 

puddle lamp operation signal through the BCAN if a smart key is identified.

The SKM starts to search for a smart key 30 sec. after the vehicle has entered the theft deterrent 

mode.

Continuous operation

▶

Reset conditions

▶

Standby mode operation

▶

When a smart key is identified within 1 m from the vehicle in theft deterrent mode, the SKM sends the 

puddle lamp operation signal (10 min. timer activated) through the BCAN. If a smart key is 

continuously found within 10 min. the SKM sends the puddle lamp signal again for continuous 

operation (up to 2 times within 10 min.)

The SKM starts to search for a smart key 30 sec. after sending the 1st puddle lamp operation signal. 

If a smart key is found, the SKM sends the 2nd operation signal.

The SKM sends the signals for [AUTO approach], [REKES UNLOCK] and [Passive UNLOCK] through 

the BCAN to control the puddle (approach) lamp by AUTO puddle (approach) lamp ON, REKES 

UNLOCK and Passive entry UNLOCK.

Default setting is AUTO approach.
