System DescriptionEIS009AY
DESCRIPTION
Operation Flow

Setting the vehicle security system
Initial condition

Ignition switch is in OFF position.
Disarmed phase

When the vehicle is being driven or when any door is open, the vehicle security system is set in the dis-
armed phase on the assumption that the owner is inside or near the vehicle.
Pre-armed phase and armed phase

The vehicle security system turns into the "pre-armed" phase (security lamp illuminates) when the BCM
receives LOCK signal from front door key cylinder switch, keyfob or Intelligent Key after all doors are
closed.

All doors are closed after front doors are locked by key or door lock and unlock switch.
The security indicator lamp illuminates for 30 seconds. then, the system automatically shifts into the "armed"
phase.
Canceling the set vehicle security system
The armed phase is canceled when the driver unlocks the doors with the key, keyfob or Intelligent Key.
Activating the alarm operation of the vehicle security system
Make sure the system is in the armed phase.
When one of the following operations is performed, the system sounds the horns and flashes the headlamps
for about 50 seconds.
1. Any door is opened before unlocking door with key, keyfob or Intelligent Key.
2. Door is unlocked without using key, keyfob or Intelligent Key.

to IPDM E/R internal CPU.

through 20A fuse (No. 53, located in the IPDM E/R)

to IPDM E/R internal CPU.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 20, located in the fuse block (J/B)]

to BCM terminal 11.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 6, located in the fuse block (J/B)]

to BCM terminal 38.
Ground is supplied

to BCM terminal 67

through body grounds M57 and M61.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors.
To activate the vehicle security system, BCM must receive signals indicating the ignition switch is OFF, doors
are closed and locked.
When a door is open, BCM terminal 12, 13, 43, 47 or 48 receives a ground signal from each door switch. In
addition to BCM, when back door is open, the Intelligent Key unit terminal 23 receives a ground signal from
back door through BCM terminal 30.
When front door LH is unlocked, BCM terminal 46 receives a signal from terminal 6 of main power window and
door lock/unlock switch.
When front door RH is unlocked, BCM terminal 46 receives a signal from terminal 2 of power window and door
lock/unlock switch RH.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by

opening a door

unlocking door without using the key, keyfob or Intelligent Key.
The vehicle security system will be triggered once the system is in armed phase,

when BCM receives a ground signal at terminals 12, 13, 47, 48 (front or rear door switch), or terminal 43
(back door switch).
When the vehicle security system is triggered, ground is supplied intermittently

from IPDM E/R terminal 45

to horn relay terminal 1.
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 50 seconds, but will reactivate if the vehicle is tampered with again.
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door must be unlocked with the key, keyfob or Intelligent Key.
When the key is used to unlock the driver door, BCM terminal 7 receives signal

from terminal 3 of the front door key cylinder switch LH.
When the BCM receives this signal or unlock signal from keyfob or Intelligent Key or front door key cylinder
switch LH, the vehicle security system is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
Intelligent Key and remote keyless entry system may or may not operate vehicle security system (horn and
headlamps) as required.
When the remote keyless entry system is triggered, ground is supplied intermittently

from IPDM E/R terminal 45

to horn relay terminal 1.
The headlamp flashes and the horn sounds intermittently.

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,

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.
Ground is supplied

through grounds E15 and E24,

to rear combination lamp LH terminal 1

through grounds B7 and B19,

to rear combination lamp RH terminal 1

through grounds B117, B132 and D402.
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.

System DescriptionEKS00HZK
When room lamp switch is in DOOR position, room lamp ON/OFF is controlled by timer according to signals
from switches including key switch, front door switch LH, unlock signal from keyfob, door lock and unlock
switch, key cylinder lock and unlock switch, ignition switch.
When room lamp turns ON, there is a gradual brightening over 1 second.
When room lamp turns OFF, there is a gradual dimming over 1 second.
Interior room lamp timer is controlled by BCM (body control module).
Interior room lamp timer control settings can be changed with CONSULT-II.
POWER SUPPLY AND GROUND
Power is supplied at all times (without Intelligent Key system)

through 10A fuse [No. 14, located in fuse block (J/B)]

to key switch and key lock solenoid terminal 2,

through 10A fuse [No. 8, located in fuse block (J/B)]

to BCM terminal 57,

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

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 will not be supplied to Intelligent Key unit terminal 27.
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 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 or front door key cylinder switch LH).

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 30 minutes after ignition switch is turned off.
After lamps are turned OFF by the battery saver system, the lamps illuminate again when

front door key cylinder switch LH 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-II.
