ID Code Entry ProcedureAIS004MT
KEY FOB ID SET UP WITH CONSULT-II
NOTE:

If a key fob is lost, the ID code of the lost key fob must be erased to prevent unauthorized use. A
specific ID code can be erased with CONSULT-II. However, when the ID code of a lost key fob 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 key fobs must be re-registered.

When registering an additional key fob, the existing ID codes in memory may or may not be
erased. If four ID codes are stored in memory, when an additional code is registered, only the old-
est 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 four ID codes are entered, the oldest
ID code will be erased.

Even if same ID code that is already in the memory is input, the same ID code can be entered. The
code is counted as an additional code.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Turn ignition switch “OFF”.
2. Connect “CONSULT-II” and “CONSULT-II CONVERTER” to the
data link connector.
3. Turn ignition switch ON.

INTELLIGENT KEY SYSTEM
Revision: 2004 November 2004 FX35/FX45
System DescriptionAIS004MW

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 communications between the Intelligent Key and the
vehicle

Operation of the remote control buttons on the Intelligent 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 locked or unlocked with entry switch or remote control-
ler button operation, the hazard lamps flash and the Intelligent Key warning buzzer sounds.

Even if the vehicle or Intelligent Key battery runs 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, change the function setting and register an Intelligent
Key with the CONSULT-II.
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
verification is performed using two-way communication with Intelligent Key, and if ID is successfully veri-
fied, 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.
