INTERIOR ROOM LAMPPFP:26410
Component Parts and Harness Connector LocationNKS003T0
System DescriptionNKS003T1
BCM (body control module) controls interior lamp, room lamp timer and interior lamp battery saver.
The following signals are input to BCM:
Door lock/unlock trunk open request signal from the Intelligent Key unit via CAN communication
Key cylinder switch status signal from power window main switch via power window serial link
Door switch signal from door switches (driver side, passenger side, rear LH and RH)
IGN power supply (signal) from PDU (power distribution unit)
ACC power supply (signal) from PDU
ROOM LAMP TIMER BASIC OPERATION
Applicable lamps
Room lamp system: map lamp, foot lamp (driver side and passenger side) and personal lamp (rear LH
and rear RH).
1. When getting on the vehicle
Lamps illuminate by timer operation when driver side door or passenger side door is unlocked.*
Lamps illuminate by timer operation after any door is open and then all doors are closed.*
Timer operation stops and lamps are OFF, when driver side door is locked or the push-button ignition
switch (push switch) is turned to ACC or ON from OFF.
*: This setting can be changed by CONSULT-II. Refer to LT- 2 8 5 , "
WORK SUPPORT (INT LAMP)" .

INTERIOR ROOM LAMP
Revision: 2006 January2006 M35/M45
2. When getting off the vehicle
Lamps illuminate by timer operation when the push-button ignition switch (push switch) is turned OFF.*
Lamps illuminate by timer operation after any door is open and then all doors are closed.*
Timer operation stops and lamps are OFF, when driver side door is locked.
*: This setting can be changed by CONSULT-II. Refer to LT- 2 8 5 , "
WORK SUPPORT (INT LAMP)" .
POWER SUPPLY AND GROUND
Power is supplied at all times
through 50A fusible link (letter F, located in fuse and fusible link block)
to BCM terminal 55,
through 10A fuse [No. 21, located in fuse block (J/B)]
to BCM (body control module) terminal 42,
through 10A fuse [No. 22, located in fuse block (J/B)]
to key slot terminal 1.
With the ignition switch in the ON or START position, power is supplied
through 15A fuse [No. 1, located in fuse block (J/B)]
to BCM terminal 38.
With the ignition switch in the ACC or ON position, power is supplied
through 10A fuse [No. 6, located in fuse block (J/B)]
to BCM terminal 11.
Ground is supplied
to BCM terminal 52
through grounds M16 and M70.
When the driver side door is opened, ground is supplied
to BCM terminal 62
through front door switch driver side terminal 2
through case ground of front door switch driver side.
When the passenger side door is opened, ground is supplied
to BCM terminal 12
through front door switch passenger side terminal 2
through case ground of front door switch passenger side.
When the rear door LH is opened, ground is supplied
to BCM terminal 63
through rear door switch LH terminal 2
through case ground of rear door switch LH.
When the rear door RH is opened, ground is supplied
to BCM terminal 13
through rear door switch RH terminal 2
through case ground of rear door switch RH.
When driver side door is unlocked by door lock and unlock switch, BCM receives a ground signal
to BCM terminal 22
through power window main switch (door lock and unlock switch) terminal 14 or power window sub-switch
(front passenger side) (door lock and unlock switch) terminal 16
through power window main switch (door lock and unlock switch) terminal 17 or power window sub-switch
(front passenger side) (door lock and unlock switch) terminal 11
through grounds M16 and M70.
When the driver side door is unlocked by the front door lock assembly (driver side) (key cylinder switch), BCM
receives a ground signal
to BCM terminal 22
through power window main switch (door lock and unlock switch) terminals 14 and 6

to vanity mirror lamp LH and RH terminals 2
through grounds M16 and M70.
And power is supplied
through BCM terminal 41
to vanity mirror lamp (LH and RH) terminals 1.
ROOM LAMP TIMER OPERATION
BCM controls applicable lamps to illuminate for 15 seconds (can be set maximum 30 seconds) by timer oper-
ation under following conditions. BCM also controls applicable lamps to brighten for 1 second (can be set max-
imum 5 seconds) when turned ON, or to dim for 3 seconds (can be set maximum 5 seconds) when turned
OFF. (Timer operating time and dimming/brightening time can be changed with CONSULT-II. Refer to LT- 2 8 5 ,
"WORK SUPPORT (INT LAMP)" .) This control operates as follows.
Applicable lamps
Room lamp system: map lamp, foot lamp (driver side and passenger side) and personal lamp (rear LH
and rear RH).
BCM controls room lamp timer operation under following condition.
Condition 1: Door lock state changes.*
BCM judges as the door lock is unlocked under either case below.
–The Intelligent Key unit sends door lock/unlock trunk open request signal (driver side unlock or passenger
side unlock) to BCM through CAN communication line by unlock operation of intelligent key, outside key
antenna and front door request switch (driver side) or outside key antenna and front door request switch
(passenger side).
–Key cylinder switch state (unlock) signal is sent to BCM through power window serial link when front door
lock assembly (driver side) (key cylinder switch) is unlocked (ON) by power window main switch unlock
operation.
And fulfills all the conditions below.
–The engine switch (push switch) is OFF.
–All the doors are closed.
*: This setting can be changed by CONSULT-II. Refer to LT-285, "
WORK SUPPORT (INT LAMP)" .
Condition 2: Any door switch state changes.*
The BCM terminal value of operated door switch is changed when any door is opened and then closed.
From that BCM judges as the door is opened and then closed.
And fulfills all the conditions below.
–The engine switch (push switch) is OFF.
–All the doors are closed.
*: This setting can be changed by CONSULT-II. Refer to LT-285, "
WORK SUPPORT (INT LAMP)" .
Condition 3: Engine switch (push switch) state changes.*
The Intelligent Key unit judges as the engine switch (push switch) is OFF and sends push-button ignition
switch (push switch) signal to PDU (power distribution unit) when push-button ignition switch (push
switch) turned OFF. Then PDU (power distribution unit) turns OFF, IGN power supply and ACC power
supply.
And fulfills the conditions below.
–All the doors are closed.
*:This setting can be changed by CONSULT-II. Refer to LT- 2 8 5 , "
WORK SUPPORT (INT LAMP)" .
NOTE:
When timer operation signal is input during former timer operation, BCM goes for latter timer operation.
