INTERIOR ROOM LAMP
When the map lamp, personal lamp and ignition keyhole illumination are turned ON by the interior room lamp
timer, power is supplied
through 10A fuse [No. 21, located in fuse block (J/B)]
to map lamp terminal 3
to personal lamp RH and LH terminals 2, and
to ignition keyhole illumination terminal 1.
Ground is supplied
to map lamp terminal 2
to personal lamp RH and LH terminals 1, and
to ignition keyhole illumination terminal 2
through BCM terminal 48
With power and ground supplied, the map lamp, personal lamp and ignition keyhole illumination illuminate.
Timer Operation Condition
When BCM detects driver door is unlocked, the key is not inserted in the ignition key cylinder (key switch
OFF), and ignition knob switch is OFF (with Intelligent Key system), it determines that conditions for inte-
rior room lamp timer operation are met, and turns the room lamp ON for 30 seconds.
When BCM detects key is removed from ignition key cylinder (key switch OFF), it determines that condi-
tions for interior room lamp timer operation are met, and turns the room lamp ON for 30 seconds.
When BCM detects driver door is closed, and the key is not inserted in the ignition key cylinder (key switch
OFF), and ignition knob switch is OFF (with Intelligent Key system), it determines that conditions for inte-
rior room lamp timer operation are met, and turns the room lamp ON for 30 seconds.
When ignition knob turns to OFF from ON, Intelligent Key unit sends ignition knob switch signal
(ON→OFF) through CAN communication. When BCM detect ignition knob switch is turned to OFF by igni-
tion knob switch signal (ON→OFF), and the key is not inserted in the ignition key cylinder (key switch
OFF), it determines that conditions for interior room lamp timer operation are met, and turns the room
lamp ON for 30 seconds.
BCM does not activate the timer even a door other than the driver door is opened.
*: Setting can be changed by CONSULT-II. Refer to LT- 2 3 3 , "
WORK SUPPORT (INT LAMP)" .
Conditions for Canceling Timer
Timer operation is cancelled in any of the following conditions.
Driver door is locked.
Driver door is opened.
Ignition key switch or ignition knob is ON.
INTERIOR ROOM LAMP BATTERY SAVER CONTROL
If the interior room lamp switch is in DOOR position and the lamps left illuminated due to incompletely closed
door, BCM turns OFF the room lamp and ignition keyhole illumination in 30 or 60 minutes to prevent run down
of the battery. (Timer setting can be changed by CONSULT-II. Refer to LT- 2 3 4 , "
WORK SUPPORT (BATTERY
SAVER)" .)
When the ignition key switch or ignition knob is turned from ON to OFF, the timer is activated.
When any of the following door switch signal condition is changed with the ignition key switch in OFF posi-
tion, the timer is activated when the change is occurred.
Door switch signals: front door switch (driver side and passenger side) signal, rear door switch (LH and RH)
signal, front door lock assembly signal, key switch signal, ignition knob switch signal, central door unlock
switch signal and remote control unlock signal.
