Operation Description
• When the Intelligent Key unit detects that each request sw
itch is pressed, it starts the outside key antenna
and inside key antenna corresponding to the pressed request switch and sends the request signal to the
Intelligent Key. And then, make sure that the Intelligent Key is near door.
• If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and sends the key ID signal to the Intelligent Key unit.
• Intelligent Key unit receives the key ID signal and compares it with the registered key ID.
• If the key ID check result is OK, the Intelligent Ke y unit sends the door lock/unlock request signal to BCM
(Body control module) via CAN communication line.
• Intelligent Key unit sends the door lock/unlock signal and sounds Intelligent Key warning buzzer (lock: 2 times, unlock: 1 time) at the same time.
• When BCM receives the door lock/unlock signal, it oper ates door lock actuator and flashes the hazard warn-
ing lamp (lock: 2 times, unlock: 1 time) at the same time as reminder.
Operation Condition
If the following conditions are not satisfied, door lock/unlock operations are not performed even if the request
switch is operated.
*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be unlocked from outside of the vehicle with a spare
Intelligent Key as long as Key IDs are different.
Outside Key Antenna Detection Area
The outside key antenna detection area of door lock/unloc k function is in the range of approximately 80 cm
(31.50 in) surrounding the request switch (driver side, passenger side and back door or trunk area).
Hazard and Buzzer Reminder
When all doors and trunk (sedan) are locked or unlocked by each request switch, Intelligent Key\
unit sends
hazard request signal to BCM via CAN communication line.
BCM flashes hazard warning lamps as a reminder and Intelligent Key unit sounds Intelligent Key warning
buzzer(s) as a reminder.
Operating function of hazard and buzzer reminder
* : Sedan only
Auto Door Lock Function
When all doors and trunk (sedan) are locked, ignition knob sw itch is OFF (when ignition switch is not pressed)
and key switch is OFF (when mechanical key is out of ignition key cylinder), all doors are unlocked with each
request switch.
When Intelligent Key unit does not receive the following signals within 1 minute, all doors are locked.
• Door switch is ON (door is opened)
• Trunk lamp switch (sedan) is ON (trunk is opened)
• Door lock signal from Intelligent Key button
• Ignition knob switch is ON (ignition switch is pressed)
• Key switch is ON (mechanical key is inserted in ignition key cylinder)
Auto door lock mode can be changed by “AUTO RELOCK TIMER” mode in “WORK SUPPORT”. Refer to BL-
117, "CONSULT-III Application Item".

INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors and trunk (sedan).
To activate the vehicle security system, BCM must receive signals indicating the ignition switch is OFF, doors
and trunk (sedan) are closed and locked.
When a door or trunk (sedan) is open, BCM terminal 12, 13, 42, 43, 47 or 48 receives a ground signal from
each door or trunk switch. In addition to BCM, when back door is open, the Intelligent Key unit terminal 23
receives a ground signal from back door or trunk (sedan) through BCM terminal 30.
When front door LH is unlocked, BCM terminal 46 receives a signal from terminal 6 of main power window and
door lock/unlock switch.
When front door RH is unlocked, BCM terminal 46 receives a signal from terminal 2 of power window and door
lock/unlock switch RH.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
• Opening a door without using the key, keyfob or Intelligent Key.
• Opening trunk without using the key, keyfob or Intelligent Key (sedan).
The vehicle security system will be triggered once the system is in armed phase,
• when BCM receives a ground signal at terminals 12, 13, 47, 48 (front or rear door switch), terminal 42 (sedan, trunk switch) or terminal 43 (hatchback, back door switch).
When the vehicle security system is triggered, ground is supplied intermittently
• from IPDM E/R terminal 45
• to horn relay terminal 1.
The headlamps flash and the hor n sounds intermittently.
The alarm automatically turns off after 50 seconds, but will reactivate if the vehicle is tampered with again.
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door or trunk (sedan) must be unlocked with the key, keyfob or
Intelligent Key.
When the key is used to unlock the driver door, BCM terminal 7 receives signal
• from terminal 3 of the front door lock assembly LH (key cylinder switch).
When the key is used to open the trunk (sedan), BCM terminal 41 receives signal
• from terminal 1 of the trunk key cylinder switch.
When the BCM receives an unlock signal from keyfob, Intelligent Key, front door key cylinder switch LH or
trunk key cylinder switch (sedan), the vehicle security system is deactivated (Disarmed phase).
PANIC ALARM OPERATION
Intelligent Key and remote keyless entry system may or may not operate vehicle security system (horn and
headlamps) as required.
When the vehicle security system is triggered, ground is supplied intermittently
