And power is supplied

●

from BCM terminal 24

●

ROOM LAMP TIMER OPERATION

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 and key lock solenoid terminal 3.

Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 62.
Ground is supplied

●

from BCM terminal 74

●

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 and key lock solenoid terminal 4

●

to BCM terminal 62.

When key is removed from key switch and key lock solenoid (key switch OFF), power supply to BCM terminal
62 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 14 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 keyfob 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 LAMP BATTERY SAVER CONTROL

If the room lamp remains illuminated by the door switch open signal, or if the room lamp switch is in the ON
position for more than 30 minutes after the ignition switch is turned to the OFF position, the BCM will automat-
ically turn off the map lamp, step lamp, and/or personal lamp and vanity mirror lamp.
After lamps turn OFF by the battery saver system, the lamps illuminate again when

●

signal from keyfob, 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.

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