When the driver side door is unlocked by door key cylinder switch, The BCM receives information by commu-
nicating with power window main switch
through grounds M30 and M66
to door key cylinder switch terminal 2
through door key cylinder switch terminal 1
to power window main (door lock and unlock switch) switch terminal 7
through power window main switch (door lock and unlock switch) terminal 12

When a signal, or combination of signals is received by BCM, ground is supplied
through BCM terminal 48
to map lamp terminal 2 (Coupe models)

With power and ground are supplied, map lamp illuminates.
SWITCH OPERATION
When map lamp switch is ON, ground is supplied
to map lamp terminal 1 (Coupe models)
to map lamp terminal 1 (Roadster models)
through grounds M30 and M66.
And power is supplied
through BCM terminal 41
to ignition key hole illumination terminal 1
to map lamp terminal 3 (Coupe models)
to map lamp terminal 2 (Roadster models).
When vanity mirror lamp LH and RH is ON, ground is supplied
to vanity mirror lamp LH and RH terminals 2
through grounds M30 and M66.
And power is supplied
through BCM terminal 41
to vanity mirror lamp terminal 1.
MAP LAMP TIMER OPERATION
When the map lamp switch is in the DOOR position, and when all conditions below are met, BCM performs
timer control (maximum 30 seconds) for map lamp ON/OFF.
In addition, when map lamp turns ON or OFF there is gradual brightening or dimming over 1 second.
Power is supplied at all times
to 10A fuse [No. 21 located in fuse block (J/B)]
through key switch terminal 2.
When all doors are closed (all door switches OFF) and key is removed from key cylinder (key switch OFF),
power will not be supplied to BCM terminal 37.
Ground is supplied
through BCM terminal 22
to power window main switch (door lock and unlock switch) terminal 12.
At this time, BCM detects that driver door is unlocked. It determines that map lamp timer operation conditions
are met, and turns map lamp ON for 30 seconds.
When all doors are closed (all door switches OFF) and key is in 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.

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.
