INFOID:0000000001327837
 The Intelligent Key system is a system which can lock and unlock the doors (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 comm unications between the Intelligent Key and the vehicle
 Operation of the remote control buttons on the Intelli gent Key also provides the same functions as the
remote control entry system. (Remote control entry functions)
 As an ignition key warning function, when a door is lock ed or unlocked with entry switch or remote controller
button operation, the hazard lamps flash and the Intelligent Key warning buzzer sounds.
 Even if the vehicle or Intelligent Key battery r uns down, the door can be locked and unlocked and the engine
started with the mechanical key built into the Intelligent Key.
 If an Intelligent Key was 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, c hange the function setting and register an Intelligent
Key with the CONSULT-III.
DOOR LOCK FUNCTION
Operation Description
 When the driver door, passenger door, or back door request switch is pressed, Intelligent Key unit sends a request signal from the transmission antenna corresponding to the pressed door request switch, key-ID ver-
ification is performed using two-way communication with In telligent Key, and if ID is successfully verified, a
door lock/unlock request signal is sent to BCM (Body Control Module) 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 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.

to unlock all doors to prevent Intelligent Key from becoming locked in vehicle.
CAUTION:
The above function operates when the Intelligent Key is inside the vehicle. However, there are cases
that Intelligent Key cannot be detect ed and this function will not operate when Intelligent Key is on the
instrument panel, rear parcel shelf, or in the gl ove box. Also, this system sometimes does not operate
if the Intelligent Key is in th e door pocket for the open door.
REMOTE CONTROL ENTRY FUNCTIONS
Door Lock Function
 Operating a remote controller button on the Intelligent Ke y sends the Intelligent Key-ID to the Intelligent Key
unit. Intelligent Key unit conducts a verification of the received key-ID, and if the verification is accepted, a
door lock or door unlock request signal is sent to BCM via CAN communication to lock/unlock the door.
 When door lock/unlock is performed using Intelligent Ke y remote controller button operation, operation con-
firmation is conducted by making hazard lamps flash and Intelligent Key warning buzzer sound.
OPERATION CONDITION

ler button operation, hazard lamps flash and horn sounds.
ENGINE STARTUP FUNCTION
Operation Description
 When ignition knob is pressed, Intelligent Key unit sends request signal from inside key antenna, key-ID ver- ification is conducted with Intelligent Key using two-wa y communication, and if verification is successful, an
ignition rotation prohibition latch release signal is sent to steering lock unit. Steering lock unit releases igni-
tion knob rotation prohibition latch. (Ignition knob can now be turned.)
 When it becomes possible to rotate the ignition knob, “KEY” warning lamp in combination meter lights up green to notify driver that ignition knob can be turned.
NOTE:
When it becomes impossible to rotate the ignition knob, “KEY” warning lamp in combination meter lights up
red.
 When key-ID verification is successful and ignition knob switch is in the ON state, Intelligent Key unit uses CAN communication to send engine start permission signal to BCM.
 When BCM receives engine start permission signal, it uses CAN communication to sent starter request sig-
nal to IPDM E/R so that the engine will start when ignition knob is rotated to START position.
Operation Range
Engine can be started when Intelligent Key is in the v ehicle. However, sometimes engine might not start when
Intelligent Key is on instrument panel, rear parcel shelf, or in glove box.
NOTE:
