KEYFOB ID SET UP WITH CONSULT-III
NOTE:
• If a keyfob is lost, the ID code of the lost keyfob must be erased to prevent unauthorized use. A spe-
cific ID code can be erased with CONSULT-III. However, when the ID code of a lost keyfob is not
known, all controller ID codes should be erased. After all ID codes are erased, the ID codes of all
remaining and/or new keyfobs must be re-registered.
• When registering an addi tional keyfob, the existing ID codes in memory may or may not be erased. If
five ID codes are stored in memory , when an additional code is registered, only the oldest code is
erased. If less than five ID codes are stored in memory, when an additional ID code is registered, the
new ID code is added and no ID codes are erased.
• Entry of maximum five ID codes is allowed. When more than five ID codes are entered, the oldest ID
code will be erased.
• Even if same ID code that is already in the memo ry is input, the same ID code can be entered. The
code is counted as an additional code.
1. Touch “MULTI REMOTE ENT”.
2. Touch “WORK SUPPORT”.
3. The items are shown on the figure can be set up. • “REMO CONT ID CONFIR”Use this mode to confirm if a keyfob ID code is registered or not.
• “REMO CONT ID REGIST” Use this mode to register a keyfob ID code.
NOTE:
Register the ID code when keyfob or BCM is replaced, or when additional keyfob is required.
• “REMO CONT ID ERASUR” Use this mode to erase a keyfob ID code.

INTELLIGENT KEY SYSTEM
System Description
INFOID:0000000005929328
• The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function), and start the engine (engine start func tion) by carrying around the Intelligent Key (without
some key operation), which operates based on the results of electronic ID verification using two-way com-
munications between the Intelligent Key and the vehicle (Intelligent Key unit).
• Vehicles equipped with a manual transmission include a key interlock solenoid located in the steering col- umn to prevent accidental shut-off of the ignition sw itch and locking of the steering wheel during driving con-
dition when the vehicle is moving.
CAUTION:
The driver should always carry the Intelligent Key
• Operation of the remote controller buttons on the Inte lligent Key also provides the same functions as the
remote control entry system. (Remote keyless entry functions)
• If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer
goes off to inform the driver. (Warning chime functions)
• When a door lock is locked or unlocked with request switch or remote controller button operation, the hazard
lamps flash and the buzzer (outside vehicle) sounds (Hazard and buzzer reminder function).
• Even if the Intelligent Key battery is completely discharged, the door locks can be locked and unlocked and the engine started with the mechanical key built into the Intelligent Key.
• The settings for each function can be changed with the CONSULT-III.
• If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be registered.
• It has been made possible to diagnose the system and r egister an Intelligent Key with the CONSULT-III.
DOOR LOCK/UNLOCK FUNCTION
Only when pressing the request switch, it is possible to lock and unlock the door by carrying around the Intelli-
gent Key (without some key operation).

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".
