INTERIOR ROOM LAMP TIMER OPERATION
Without Intelligent Key System
When room lamp switch is in DOOR position, and w hen all conditions below are met, BCM performs timer
control (maximum 30 seconds) for room lamp ON/OFF.
In addition, when the interior room lamp turns ON or OFF there is gradual brightening or dimming over 1 sec-
ond.
Power is supplied
• through 10A fuse [No. 14, located in fuse block (J/B)]
• to key switch and key lock solenoid terminal 2.
When the key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM termi-
nal 37.
When front door lock assembly LH (key cyli nder switch) is unlocked, ground is supplied
• to BCM terminal 7
• through front door lock assembly LH (key cylinder switch) terminal 5
• through front door lock assembly LH (key cylinder switch) terminal 4
• through grounds M57 and M61.
At the time that front door LH is opened, BCM detects that front door LH is unlocked. It determines that interior
room lamp timer operation condition is met, and turns the room lamp ON for 30 seconds.
When key is in ignition key cylinder (key switch ON),
Power is supplied
• through key switch and key lock solenoid terminal 1
• to BCM terminal 37.
When key is removed from key switch and key lock solenoid (key switch OFF), the power supply to BCM ter-
minal 37 is terminated. BCM detects that key has been re moved, determines that interior room lamp timer
conditions are met, and turns the room lamp ON for 30 seconds.
When front door LH opens → closes, and the key is not inserted in the key switch and key lock solenoid (key
switch OFF), voltage at BCM terminal 47 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.
Interior room lamp timer control is canceled under the following conditions:
• Front door LH is locked (locked by front door lock assembly LH (key cylinder switch), keyfob or door lock/
unlock switch).
• Front door LH is opened (front door switch LH).
• Ignition switch ON.
With Intelligent Key System
When the room lamp switch is in DOOR position, and when all conditions below are met, BCM performs timer
control (maximum 30 second) for room lamp ON/OFF.
In addition, when interior room lamp turns ON or OFF there is gradual brightening or dimming over 1 second.
Power is supplied
• through 10A fuse (No. 31, located in fuse and fusible link box)
• to key switch and ignition knob switch terminals 2 and 4.
When key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal
37.
When the ignition knob switch is released, power wil l not be supplied to Intelligent Key unit terminal 27.
When front door lock assembly LH (key cyli nder switch) is unlocked, ground is supplied

INTERIOR ROOM LAMP
• to BCM terminal 7
• through front door lock assembly LH (key cylinder switch) terminal 5
• through front door lock assembly LH (key cylinder switch) terminal 4
• through grounds M57 and M61.
At the time the front door LH is opened, the BCM detects the front door LH is unlocked. It determines that the
interior room lamp timer operation conditions are met, and interior room lamp ON for 30 seconds.
When the key is in ignition key cylinder (key switch ON ), or ignition knob switch is pushed, power is supplied
• through key switch and ignition knob switch terminal 1
• to BCM terminal 37, or
• through key switch and ignition knob switch terminal 3
• to Intelligent Key unit terminal 27.
When the key is removed from key switch (key switch OFF), power supply to BCM terminal 37 is terminated.
When the ignition knob switch is released, power supply to intelligent key unit is terminated. The BCM detects
that the key has been removed, determines that interior room lamp timer conditions are met, and turns room
lamp ON for 30 seconds.
When the front door LH opens → closes, and key is not inserted in key switch (or ignition knob switch is
released), BCM terminal 47 changes between 0V (door open) → 12V (door closed). BCM determines that
conditions for room lamp operation are met, and turns room lamp ON for 30 seconds.
Interior room lamp timer control is canceled under the following conditions:
• Front door LH is locked (with keyfob, front door lock assembly LH (key cylinder switch) or door lock/unlock switch).
• Front door LH is opened (front door switch LH).
• Ignition switch ON.
INTERIOR LAMP BATTERY SAVER CONTROL
If an interior room lamp is left ON, it will not be turned OFF even when door is closed.
BCM turns off interior lamp automatically to save battery 15 minutes after ignition switch is turned off.
After lamps are turned OFF by the battery saver system, the lamps illuminate again when
• front door lock assembly LH (key cylinder switch) is locked or unlocked
• door is opened or closed
• key is removed from ignition key cylinder or inserted in ignition key cylinder, or the ignition knob switch is pushed or released.
Interior lamp battery saver control time period can be changed by the function setting of CONSULT-III.
