ROOM LAMP TIMER OPERATION
Without 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 seconds ) 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 infuse block (J/B)]
 through key switch terminal 2.
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 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),
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 s witch (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 wi ndow main switch (door lock and unlock switch), door
