Revision: 2005 August
2005 Murano
System Description
AIS006BY
●
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.

DOOR LOCK/UNLOCK FUNCTION
Only when pressing the request switch, it is possible to lock and unlock the all doors by carrying around the
Intelligent Key (without some key operation).
System Diagram
Operation Description
●
When the Intelligent Key unit detects that each request switch is pressed, it starts the outside antenna cor-
responding to the pressed 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 antenna detection area, it receives the request signal and sends
the key ID signal to the Intelligent Key unit.
●
Intelligent Key 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 the Intelligent Key warning buzzer
(engine room) (lock: 1 time, unlock: 2 times) at the same time.
●
When BCM receives the door lock/unlock signal, it operates door lock actuator and flashes the hazard
lamp (lock: 1 time, unlock: 2 times) at the same time as an operation check.
