When the room lamp and personal lamp switch is in DOOR position, room lamp and personal lamp ON/OFF is
controlled by timer according to signals from switches including key switch, front door switch driver side,
unlock signal from key fob, door lock and unlock switch, key cylinder lock and unlock switch, ignition switch.
When the room lamp and personal lamp turns ON, there is a gradual brightening over 1 second. When room
lamp and personal lamp turns OFF, there is a gradual dimming over 1 second.
The room lamp and personal lamp timer is controlled by the BCM (body control module).
Room lamp and personal lamp timer control settings can be changed with CONSULT-II.
Ignition key hole illumination turns ON at time when driver door is opened (door switch ON) or removed key
fob from key cylinder. Illumination turns OFF when driver door is closed (door switch OFF).
Step lamp turns ON at time when driver door or passenger door is opened (door switch ON). Lamp turns OFF
when driver, passenger doors are closed (all door switches OFF).

ROOM LAMP TIMER OPERATION
Without Intelligent Key System

When room lamp and personal lamp switch is in DOOR position, and when all conditions below are met, BCM
performs timer control (maximum 30 seconds) for room lamp and personal lamp ON/OFF.
In addition, when spot turns ON or OFF there is gradual brightening or dimming over 1 second.
Power is supplied

through 10A fuse [No. 21, located in the fuse block (J/B)]

to key switch terminal 3.

Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 37.
Ground is supplied

from BCM terminal 22

to power window main switch (door lock and unlock switch) terminal 14.

At this time, BCM detects that driver door is unlocked. It determines that room lamp and personal lamp timer
operation conditions are met, and turns the room lamp and personal lamp ON for 30 seconds.
Key is in ignition key cylinder (key switch ON),
Power is supplied

through key switch terminal 4

to BCM terminal 37.

When key is removed from key switch (key switch OFF), power supply to BCM terminal 37 is terminated. BCM
detects that key has been removed, determines that room lamp and personal lamp timer conditions are met,
and turns the room lamp and personal lamp ON for 30 seconds.
When driver door opens 

 closes, and the key is not inserted in the key switch and key lock solenoid (key

switch OFF), BCM terminal 62 changes between 0V (door open) 

 12V (door closed). The BCM determines

that conditions for room lamp and personal lamp operation are met and turns the interior lamp ON for 30 sec-
onds.
Timer control is canceled under the following conditions.

Driver door is locked [when locked key fob or power window main switch (door lock and unlock switch),
door key cylinder switch]

Driver door is opened (driver door switch turns ON)

Ignition switch ON.

INTERIOR ROOM LAMP

Revision: 2006 August

2006 Murano

With Intelligent Key System

When the room lamp and personal lamp switch is in DOOR position, and when all conditions below are met,
BCM performs timer control (maximum 30 second) for room lamp and personal lamp ON/OFF.
In addition, when spot turns ON or OFF there is gradual brightening or dimming over 1 second.
Power is supplied

to 10A fuse [No. 22, located in fuse and fuse block (J/B)]

through key switch and ignition knob switch terminals 1 and 3.

Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 37. 
And not turned ignition knob switch, power will not be supplied to Intelligent Key unit.
Ground is supplied

from BCM terminal 22

to power window main switch (door lock and unlock switch) terminal 14.

At the time that driver door are opened, BCM detects that driver door is unlocked. It determines that room
lamp and personal lamp timer operation conditions are met, and turns room lamp and personal lamp ON for
30 seconds.
Key is in ignition key cylinder (key switch ON), or turned ignition knob switch,
Power is supplied

through key switch terminal 4

to BCM terminal 37,

through key switch terminal 2

to intelligent key unit terminal 27.

When the key is removed from key switch (key switch OFF), power supply to BCM terminal 37 is terminated.
And turned ignition knob switch, power supply to Intelligent Key unit is terminated. BCM detects that key has
been removed, determines that room lamp and personal lamp timer conditions are met, and turns room lamp
and personal lamp ON for 30 seconds.
When driver door opens 

 closes, and key is not inserted in key switch (or not turned ignition knob switch),

BCM terminal 62 changes between 0V (door open) 

 12V (door closed). BCM determines that conditions for

room lamp and personal lamp operation are met and turns the room lamp ON for 30 seconds. 
Timer control is canceled under the following conditions.

Driver door is locked [when locked key fob, power window main switch (door lock and unlock switch) or
door key cylinder switch].

Driver door is opened (driver door switch terns ON).

Ignition switch ON.

INTERIOR LAMP BATTERY SAVER CONTROL

If interior lamp is left “ON”, it will not be turned out even when door is closed.
BCM turns off interior lamp automatically to save battery 30 minutes after ignition switch is turned off.
BCM controls interior lamps listed below:

Luggage room lamp

Vanity mirror lamp

Room lamp

Personal lamp

After lamps turn OFF by battery saver system, lamps illuminate again when

signal from key fob, or power window main switch (door lock and unlock switch) or key cylinder is locked
or unlocked,

door is opened or closed,

key is removed from ignition key cylinder or inserted in ignition key cylinder, or turned ignition knob switch.

Interior lamp battery saver control period can be changed by the function setting of CONSULT-II.
