INTELLIGENT KEY SYSTEM
Revision: 2006 January2006 M35/M45
System DescriptionNIS001X8
The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function), open the trunk (trunk open function), and start the engine (engine start function) by carry-
ing around the Intelligent Key (without some key operation), which operates based on the results of elec-
tronic ID verification using two-way communications between the Intelligent Key and the vehicle
(Intelligent Key unit).
CAUTION:
The driver should always carry the Intelligent Key
Operation of the remote controller buttons on the Intelligent Key also provides the same functions as the
remote controller 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, unlocked or trunk open with request switch or remote controller button opera-
tion, the hazard lamps flash and the Intelligent Key warning buzzer or horn sounds (Hazard and buzzer/
horn reminder function).
Even if the Intelligent Key battery is completely discharged, the door locks can be locked and unlocked
with the mechanical key built into the Intelligent Key, and then initiates engine by inserting Intelligent Key
into key slot.
The settings for each function can be changed with the CONSULT-II.
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 register an Intelligent Key with the CONSULT-II.
DOOR LOCK/UNLOCK/TRUNK OPEN FUNCTION
Only when pressing the request switch, it is possible to lock and unlock the door and open the trunk by carry-
ing around the Intelligent Key (without some key operation).
System Diagram
Operation Description/Door Lock/Unlock
When the Intelligent Key unit detects that each door request switch is pressed, it starts the outside key
antenna and inside key antenna corresponding to the pressed door request switch and sends the request
signal to the Intelligent Key. And then, make sure that the Intelligent Key is near the 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 via remote keyless entry receiver.
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 Key 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 buzzer warning (lock: 1
time, unlock: 2 times) at the same time.

CHANGE SETTINGS FUNCTION
The settings for each function can be changed with the CONSULT-II.
Changing Settings Using CONSULT-II
The settings for the Intelligent Key system functions can be changed using CONSULT-II (WORK SUPPORT).
Refer to BL-83, "
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.
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 Technical Bulletin.
STEERING LOCK UNIT REGISTRATION
Steering Lock Unit ID Registration
CAUTION:
The method for registering a steering lock unit ID depends on the status of the steering lock unit
and Intelligent Key unit (new or old unit).
After registration is completed, press ignition switch with an Intelligent Key in the vehicle so that it
can be turned, and confirm that it cannot be turned even when ignition switch is pressed without
an Intelligent Key in the vehicle.
For future information, see Technical Bulletin.
CAN Communication System DescriptionNIS001X9
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNIS001XA
Refer to LAN-34, "CAN Communication Unit" .
