INTELLIGENT KEY SYSTEM

Revision: 2006 August

2006 Murano

System Description

NIS0017D

●

The Intelligent Key system is a system that makes it possible to lock and unlock the all doors lock (door
lock/unlock function), and start the engine (engine start function) by carrying around the Intelligent Key
(without some key operation), which operates based on the results of electronic 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 or unlocked with request switch or remote controller button operation, the haz-
ard lamps flash and the buzzer (outside vehicle) sounds (Hazard and horn reminder function).

●

Even if the Intelligent Key battery is completely discharged, the door locks can be locked and unlocked
and the engine started with the mechanical key built into the Intelligent Key.

●

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.

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 the CONSULT-II Operation Manual NATS.

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 a portable unit in the vehicle so that it
can be turned, and confirm that it cannot be turned even when ignition switch is pressed without a
portable unit in the vehicle.

For future information, see the CONSULT-II Operation Manual NATS.

CAN Communication System Description

NIS0017E

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.
