INTELLIGENT KEY SYSTEM
System DescriptionBIS000WZ
The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock
function) and start the engine (engine start function) by carrying around the Intelligent Key, which operates
based on the results of electrical key-ID verification using two-way communications between the Intelli-
gent Key and the vehicle
Operation of the remote control buttons on the Intelligent Key also provides the same functions as the
remote keyless entry system. (Remote keyless entry functions)
As an ignition key warning function, when a door lock is locked or unlocked with request switch or remote
controller button operation, the hazard lamps flash and the Intelligent Key warning buzzer sounds.
Even if the Intelligent Key battery runs down, the door locks can be locked and unlocked and the engine
started with the mechanical key built into the Intelligent Key.
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, change the function setting and register an Intelligent
Key with the CONSULT-II.
DOOR LOCK/UNLOCK, TRUNK OPEN FUNCTION
Operation Description
When the driver door, passenger door, or trunk open request switch is pressed, Intelligent Key unit sends
a request signal from the outside key antenna corresponding to the pressed request switch, key-ID verifi-
cation is performed using two-way communication with Intelligent Key, and if ID is successfully verified, a
door lock/unlock request signal is sent to BCM using CAN communication to lock/unlock the door lock.
When door is locking, door is unlocked, when door is unlocking, door is locked.
When door lock is locked/unlocked by door request switch operation, hazard lamps flash and Intelligent
Key warning buzzer sounds.
With the locking operation of door request switch, door lock actuators of all door are locked.
When trunk open request switch is pushed, trunk lid is opened.

INTELLIGENT KEY SYSTEM
CHANGE SETTINGS FUNCTION
The settings for each function can be changed with the CONSULT-II or Intelligent Key operation.
Changing Settings With the Intelligent Key
Intelligent Key remote controller button and door request switch operations change the engine startup function
settings (startup enabled/disabled) for each Intelligent Key independently.
Settings Change Procedure
1. With the ignition switch is in the LOCK position (ignition knob not pressed), hold down both the LOCK and
UNLOCK remote control buttons on the Intelligent Key at the same time for at least 10 seconds (The yard-
stick is that the Intelligent Key LED flashes 20 times.)
2. Within 5 seconds of releasing the Intelligent Key remote controller buttons, press the driver door request
switch.
3. The KEY warning lamp in combination meter lights up for 3 seconds (engine starting enabled → starting
disabled: lights up red, engine starting disabled → flashes green). This completes the settings change.
Changing Settings Using CONSULT-II
The settings for the Intelligent Key system functions can be changed using CONSULT-II (WORK SUPPORT).
Refer to BL-94, "
WORK SUPPORT" .
NOTE:
Once a function setting is changed, it will remain effective even if the battery is disconnected.
INTELLIGENT KEY REGISTRATION
Intelligent Key-ID registration is performed using the CONSULT-II. Up to 4 can be registered.
CAUTION:
After a new Intelligent Key-ID is registered, be sure to check the function.
When registering an additional Intelligent Key-ID, take any Intelligent Keys already registered and
Intelligent Keys for any other vehicles out of the vehicle before starting.
CONSULT-II can be used to check and delete Intelligent Key-IDs.
For future information, see the CONSULT-II Operation Manual NATS.
