(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
1. 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.

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.
1. When the outside door handle switch is operated, the SKM verifies if a smart key is outside the
vehicle using the corresponding exterior antenna.
2. 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.
3. 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.
4. 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.
▶ Smart key search mode
1. 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.
2. The system identifies the smart keys by using the outside door handle antenna on the door
handle switch which has sent the signal.
3. Smart key search input: The last door is opened and then closed. Outside door handle switch,
Brake switch, START switch (Tailgate open request)
4.
Exceptional mode
If the door handle switch is pressed and a normal smart key is found within the door handle
antenna actuation area, the system starts to find a smart key:
- when the theft deterrent mode of BCM is deactivated.
- which function is restricted when the BCM is in theft deterrent mode.
