ID Code Entry ProcedureINFOID:0000000001327833
KEY FOB ID SET UP WITH CONSULT-III
NOTE:
If a key fob is lost, the ID code of the lost key fo b must be erased to prevent unauthorized use. A spe-
cific ID code can be erased with CONSULT-III. Ho wever, when the ID code of a lost key fob is not
known, all controller ID codes sh ould be erased. After all ID codes are erased, the ID codes of all
remaining and/or new key fobs must be re-registered.
1. Touch “WORK SUPPORT”.
2. The items are shown on the figure can be set up.  “REMO CONT ID REGIST”Use this mode to register a key fob ID code.
NOTE:
Register the ID code when key fob or BCM is replaced, or when additional key fob is required.
 “REMO CONT ID ERASUR” Use this mode to erase a key fob ID code.
 “REMO CONT ID CONFIR” Use this mode to confirm if a key fob ID code is registered or not.

INTELLIGENT KEY SYSTEM
System Description
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.
Driver side door request switch operation
 When door request switch (driver side) is pushed (unlock), driver side door lock actuator is unlocked. (Selec-
tive door unlock function)
 When door request switch (driver side) is pushed (unlock) for the second time within 5 seconds after the first
operation, door lock actuators on pass enger's and other's doors are unlocked.
