When driver door opens → closes, and key is not inserted in key switch (key switch OFF), BCM terminal 62
changes between 0V (door open) → 5V (door closed). BCM determines that conditions for spot lamp opera-
tion are met and turns interior lamp ON for 30 seconds.
Timer control is canceled under the following conditions.
Driver door is locked (When locked key fob 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 door switch open signal, or if room lamp switch is in the ON position
for more than 30 minutes after the ignition switch is turned to the OFF position, BCM will automatically turn off
map lamp, luggage room lamp (Coupe models), trunk room lamp (Roadster models) and vanity mirror lamp.
After lamps turn OFF by battery saver system, the lamps illuminate again when
signal from key fob, 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-III.
