Power is supplied

through key switch terminal 1

to BCM terminal 37.
When the 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 interior room lamp and map lamp timer conditions
are met, and turns interior room lamp and map lamp ON for 30 seconds.
When driver door opens → closes, and key is not inserted in key switch (key switch OFF), BCM terminal 62
changes between 0V (door open) → 12V (door closed). BCM determines that conditions for interior room lamp
and map lamp operation are met and turns interior room lamp ON for 30 seconds.
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.
With Intelligent Key System
When the interior room lamp and map lamp switch is in DOOR position, and when all conditions below are
met, BCM performs timer control (maximum 30 second) for interior room lamp and map lamp ON/OFF.
In addition, when spot turns ON or OFF there is gradual brightening or dimming over 1 second.
Power is supplied

to 15A fuse [No. 22, located in fuse and fuse block (J/B)]

through key switch and ignition knob switch terminal 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 interior
room lamp and map lamp timer operation conditions are met, and turns interior room lamp and map 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 and ignition knob switch terminal 4

to BCM terminal 37,

through key switch and ignition knob 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 interior room lamp and map lamp timer conditions are met, and turns interior
room lamp and map 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
interior room lamp and map lamp operation are met and turns interior room lamp ON for 30 seconds.
