The BCM also supplies input to combination meter across the CAN communication lines. This input is pro-
cessed by unified meter control unit in combination meter, which in turn supplies ground to the left and right
turn signal indicator lamps.
With power and input supplied, BCM controls flashing of hazard warning lamps.
REMOTE KEYLESS ENTRY SYSTEM OPERATION
Power is supplied at all times

through 40A fusible link (letter g , located in fuse, fusible link and relay box)

to BCM terminal 70,

through 10A fuse [No. 13, located in fuse block (J/B)]

to combination meter terminal 27.
Ground is supplied

to BCM terminal 67 and

to combination meter terminals 21, 22 and 23

through grounds M57 and M61.
When the remote keyless entry system is triggered by input from the keyfob, the BCM supplies power

through BCM terminal 60

to front combination lamp LH terminal 4 and

to rear combination lamp LH terminal 6,

through BCM terminal 61

to front turn signal lamp RH terminal 4 and

to rear combination lamp RH terminal 6.

The BCM also supplies input to combination meter via the CAN communication lines. This input is processed
by the unified meter control unit in combination meter, which in turn supplies ground to the left and right turn
signal indicator lamps.
With power and ground supplied, BCM controls flashing of hazard warning lamps when keyfob is used to acti-
vate remote keyless entry system.

INTERIOR ROOM LAMP TIMER OPERATION
Without Intelligent Key System
When room lamp switch is in DOOR position, and when 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 key cylinder switch LH is unlocked, ground is supplied

to BCM terminal 7

through front door key cylinder switch LH terminal 3

through front door key cylinder switch LH terminal 2

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 removed, 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 front door key cylinder switch LH).

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.
