(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
1. The SKM receives the tailgate open switch signal from the BCM through the BCAN
communication.
2. 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.
1. 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.
2. 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.
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.
▶ 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. 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.
3. 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.
4. Smart key search input: The last door is opened and then closed. Outside door handle switch,
Brake switch, START switch (Tailgate open request)
