(1) Passive entry actuation area
Passive entry actuation area ▶Searching for a smart key signal from the outside the vehicle is prioritized in theft deterrent mode.
Searching for a smart key signal from the inside is prioritized when the theft deterrent mode is
deactivated.
The smart key verification is performed only for the driver's or passenger's door which has received
the input from the corresponding door handle switch. If a verified smart key is found, the passive entry
function is performed.
A maximum of 3 keys can be registered. -
-
- The passive LOCK/UNLOCK is performed by the input from the outside door handle switch.
(For driver's door LOCK/UNLOCK)

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) 1.

3.Smart key search mode ▶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. 1.

(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. 1.
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. 1.

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.
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)

(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. 1.
2.
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. 1.
2.
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) 1.
