ID Code Entry Procedure

AIS002G2

KEY FOB ID SET UP WITH CONSULT-II

CAUTION:

If CONVERTER is not connected with CONSULT-II, vehicle occur the “FAIL-SAFE MODE” which is
“LIGHT UP THE HEADLAMP” and/or “COOLING FAN ROTATING” when CONSULT-II is started.

NOTE:

●

When registering an additional key fob, the existing ID codes in memory may or may not be
erased. If five 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 five 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.

Turn ignition switch “OFF”.

Connect “CONSULT-II” and “CONSULT-II CONVERTER” to
data link connector.

Turn ignition switch ON.

Touch “START (NISSAN BASED VHCL)”.

Touch “BCM”.
If “BCM” is not indicated, go to

Revision: 2005 August

2005 Murano

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.
To erase all ID codes in memory, register one ID code (key fob) five times. 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 five
ID codes are stored in memory, when an additional code is registered, only the oldest 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.

●

If you need to activate more than two additional new key fobs, repeat the procedure “Additional ID code
entry” for each new key fob.

●

Entry of maximum five ID codes is allowed. When more than five 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.

INTELLIGENT KEY SYSTEM

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.

INTELLIGENT KEY SYSTEM

Revision: 2005 August

2005 Murano

Operation Condition

If the following conditions are not satisfied, door lock/unlock operation is not performed even if the request
switch is operated.

Outside Key Antenna Detection Area

The outside key antenna detection area of door lock/unlock function
is in the range of approximately 80 cm (31.50 in) surrounding the
front door request switch (driver side, passenger side) (1) and the
back door request switch (2). However, this operating range
depends on the ambient conditions.

Key Reminder Function

Key reminder functions have the following 2 functions.

CAUTION:

●

The above function operates when the Intelligent Key is inside the vehicle. However, there may be
times when the Intelligent Key cannot be detected, and this function will not operate when the
Intelligent Key is on the instrument panel, or in the glove box. Also, this system sometimes does
not operate if the Intelligent Key is in the door pocket for the open door.

Selective Unlock Function for Driver Side

When an LOCK signal is sent from door request switch (driver side), all doors will be locked.
When an UNLOCK signal is sent from door request switch (driver side) once, driver's door will be unlocked.
Then, if an UNLOCK signal is sent from door request switch (driver side) again within 5 seconds, all other door
will be unlocked.

Selective Unlock Function for Passenger Side

When an LOCK signal is sent from request switch (passenger side), all doors will be locked.
When an UNLOCK signal is sent from request switch (passenger side) once, Intelligent Key unit turns on pas-
senger side select unlock relay. And then passenger's door will be unlocked.
If an UNLOCK signal is sent from request switch (passenger side) again within 5 seconds, all other door will
be unlocked.
