[WITH INTELLIGENT KEY SYSTEM]

VEHICLE SECURITY SYSTEM

BCM shifts the phase as follows and the phase information is sent to siren control unit via communication line.

Disarmed Phase

When the vehicle is being driven or when doors are open, the theft warning system is set in the disarmed
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 when ignition switch is in OFF position, all doors
are closed and locked (using Intelligent Key, door request switch or auto relock function). 10 seconds after the
lock operation, the system automatically shifts into the armed phase.

Condition of Activating The System

When the following condition is performed in armed phase, the system sounds the horns/siren and flashes the
head lamps for about 30 seconds.
• Hood or any door is opened.
• Ultra sonic sensor is triggered.
• Ignition switch goes ON with invalid transponder ID.

Condition of Deactivating The System

When one of the following operations is performed, the armed phase is canceled.
• Unlock the doors with Intelligent Key or door request switch.
• Ignition switch goes ON with transponder ID verified.

SIREN CONTROL UNIT

Siren control unit manages siren. The siren control unit does not shift to armed phase in the same way as
BCM. The siren control unit goes to armed phase after about 10 seconds from lock command. If door is
opened or closed within about 20 seconds, only the siren will be activated.
Siren control unit has battery inside. If disconnect or connect battery terminal before canceling armed phase,
siren will be activated.

CAUTION:

When replace siren control unit (new one and used one), Perform “C/U INITALIZATION” with CON-
SULT-III.

Ultra Sonic Sensor Function

The ultra sonic sensor consist of two separate units, a transmitter on the left and receiver on the right mounted
on room mirror. The LH transmitter sensor sends an ultra sonic pulse of sound, and RH receiver sensor
receives the returning echo pulse.
It is possible to exclude the ultrasonic sensors.
To exclude the ultra sonic sensors:
1.

Turn the ignition switch from the OFF to the ON position.

2.

Turn the ignition switch from OFF to ON 3 times within 7 seconds.

3.

Close the doors, bonnet and press the lock button on the Intelligent Key to lock all doors.

The ultra sonic sensors are now excluded from the alarm system. All other functions of the system remain acti-
vated until the alarm system is disarmed again.
