through key switch terminal 1

to BCM terminal 37.
When 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 the interior room lamp and map lamp ON for 30 seconds.
When driver door opens → closes, and the key is not inserted in the key switch (key switch OFF), BCM termi-
nal 62 changes between 0V (door open) → 12V (door closed). The BCM determines that conditions for inte-
rior room lamp and map lamp operation are met and turns the 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 interior room lamp and map lamp switch is in DOOR position, and when all conditions below are met,
