SWITCH OPERATION
When front map lamp switch is ON, ground is supplied
lto front map lamp terminal 2
lthrough grounds M21, M80 and M83.
When room lamp switch is ON, ground is supplied through room lamp case ground.
ROOM LAMP TIMER OPERATION
When 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.
Power is supplied
lthrough 10A fuse [No. 22, located in fuse block (J/B)]
lto key switch terminal 2.
Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 5.
At the time that driver's door is opened, BCM detects that driver's door is unlocked. It determines that room
lamp timer operation conditions are met, and turns the interior room lamps ON for 30 seconds.
Key is in ignition key cylinder (key switch ON), power is supplied
lthrough key switch terminal 1
lto BCM terminal 5.
When key is removed from key switch (key switch OFF), power supply to BCM terminal 5 is terminated. BCM
detects that key has been removed, determines that room lamp timer conditions are met, and turns the interior
room lamps ON for 30 seconds.
When driver's door opens®closes, and the key is not inserted in the key switch (key switch OFF), BCM ter-
minal 15 changes between 0V (door open)®12V (door closed). The BCM determines that conditions for
room lamp operation are met and turns the room lamp ON for 30 seconds.
Timer control is canceled under the following conditions.
lDriver's door is opened [front door switch (driver side)].
lIgnition switch ON.
lKeyfob
INTERIOR LAMP BATTERY SAVER CONTROL
If interior lamp is left ON, it will not be turned off even when door is closed.
BCM turns off interior lamp automatically to save battery 30 minutes after ignition switch is turned off.
BCM controls interior lamps listed below:
lFront map lamp
lRoom lamp
lKey ring lamp
After lamps turn OFF by the battery saver system, the lamps illuminate again when
lsignal received from keyfob or key cylinder is locked or unlocked,
ldoor is opened or closed,
lkey 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-II. Refer toLT-
158, "WORK SUPPORT".
