• to combination meter terminal 8.
Ground is supplied
• to BCM terminal 67 and
• to combination meter terminal 17
• through grounds M57, M61 and M79.
When the remote keyless entry system is triggered by input from the keyfob, the BCM, interpreting it as turn
signal is ON, outputs turn signal from BCM terminals 60 and 61.
The BCM supplies power
• through BCM terminals 60 and 61
• to front turn/fog lamp LH and RH terminal 2
• through front turn/fog lamp LH and RH terminal 3
• to grounds E9, E15 and E24,
• to door mirror LH and RH terminal 15
• through door mirror LH and RH terminal 11
• to grounds M57, M61 and M79,
• to rear turn signal lamp LH terminal 1
• through rear turn signal lamp LH terminal 3
• to grounds B7 and B19, and
• to rear turn signal lamp RH terminal 4
• through rear turn signal lamp RH terminal 6
• to grounds B117 and B132.
BCM sends signal to combination meter through CAN communication lines, and turns on turn signal indicator
lamps within combination meter.
With power and input supplied, the BCM controls the flashing of the hazard warning lamps when keyfob is
used to activate the remote keyless entry system.

ROOM LAMP TIMER OPERATION
When lamp switch is in DOOR position and all conditions below are met, BCM performs timer control (maxi-
mum 30 seconds) for interior room lamp and map lamp ON/OFF.
Power is supplied
• through 10A fuse [No. 19, located in the fuse block (J/B)]
• to key switch and key lock solenoid terminal 3.
Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 37.
Serial data is supplied
• to BCM terminal 22
• through main power window and door lock/unlock switch terminal 14.
At the time that front door LH is opened, BCM detects that front door LH is unlocked. It determines that interior
room lamp and map lamp timer operation conditions are met, and turns the interior room lamps ON for 30 sec-
onds.
Key is in ignition key cylinder (key switch ON), power is supplied
• through key switch and key lock solenoid terminal 4
• to BCM terminal 37.
When key is removed from key switch and key lock solenoid (key switch OFF), power supply to BCM terminal
37 is terminated. BCM detects that key has been removed, determines that interior room lamp and map lamp
timer conditions are met, and turns the interior room lamps 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), BCM terminal 47 changes between 0V (door open) → 12V (door closed). The BCM determines
that conditions for interior room lamp operation are met and turns the interior room lamp ON for 30 seconds.
Timer control is canceled under the following conditions.
• Front door LH is locked [when locked by keyfob, main power window and door lock/unlock switch, or front
door lock assembly LH (key cylinder switch)]
• Front door LH is opened (front door switch LH turns ON)
• Ignition switch ON.
INTERIOR LAMP BATTERY SAVER CONTROL

LT-104
< SERVICE INFORMATION >
INTERIOR ROOM LAMP
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:
• Vanity lamp
• Room/map lamp
• Cargo lamp
• Personal lamp
• Step lamps
• Puddle lamps
• Foot lamps
• Ignition keyhole illumination
After lamps turn OFF by the battery saver system, the lamps illuminate again when
• signal received from keyfob, or main power window and door lock/unlock switch or front door lock assembly
LH (key cylinder switch) is locked or unlocked
• door is opened or closed
• key is removed from ignition key cylinder (key switch OFF) or inserted in ignition key cylinder (key switch
ON).
Interior lamp battery saver control period can be changed by the function setting of CONSULT-II.

the order of priority.
*: In conjunction with sliding the seat, the door mirrors are positioned.Function Description
Memory operation The front seat LH, steering wheel, pedals (accelerator, brake) and door mirrors move
to the stored driving position by pushing seat memory switch (1 or 2).
