(2) Passive LOCK
When the system searches for a smart key by the input from the outside door handle switch, the SKM
sends the passive LOCK signal to the BCM if all the doors are closed and a normal smart key is found
outside the vehicle.
Passive LOCK 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.
The SKM sends the signal to the BCM and instrument cluster when the warning and indicator
display conditions are met. 1.
2.
Passive LOCK by outside door handle switch ▶
When the ignition status is OFF, ACC ON or IGN ON, the SKM performs the verification procedure if the
LOCK signal is received from the driver/passenger door handle switch.
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 LOCK command] to the BCM through the BCAN if a smart
key is identified as being outside the vehicle.
If no smart key is verified 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 unlocked with the ignition status ACC ON, the SKM changes the ignition
status to OFF and sends the signal for [Passive LOCK command] to the BCM through the BCAN to
lock the door. The BCM ignores the signal if the ignition status is IGN ON.
The SKM recovers the deactivated smart key function inside the vehicle when it receives the theft
deterrent deactivation signal from the BCM through the BCAN communication. 1.

(6) Limitations/Interruption of smart key function
The SKM searches for a smart key inside the vehicle when it receives the information on entering the
theft deterrent mode from the BCM. If a normal smart key is identified, the SKM memorizes this as a
function-limited key (Silent Smart Key) or a function interrupted key (Deactivation Smart Key) according
to the conditions.
If a smart key, which outputs the door LOCK signal, is found inside the vehicle, the SKM memorizes
all the smart keys inside the vehicle as function limited keys (Silent Smart Key).
The function limited smart key provides the passive START, ignition status change and REKES
functions except the passive UNLOCK function. -
