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 3 ,
"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- 2 8 3 , "
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- 2 8 3 , "
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 3 , "
WORK SUPPORT (INT LAMP)" .
NOTE:
When timer operation signal is input during former timer operation, BCM goes for latter timer operation.
