VEHICLE SECURITY SYSTEM

• When the vehicle security system is in the disarmed phase, the security indicator lamp blinks every 2.4 sec-

onds.

Pre-armed Phase and Armed Phase

When the following operation is performed, the vehicle security system turns into the “pre-armed” phase. (The
security indicator lamp illuminates.)

BCM receives LOCK signal from front door request switch, Intelligent Key or door key cylinder, after back
door and all doors are closed.

Security indicator lamp illuminates for 30 seconds. Then, the system automatically shifts into the “armed”
phase.

CANCELING THE SET VEHICLE SECURITY SYSTEM

When one of the following operations is performed, the armed phase is canceled.

Unlock the all doors with the door request switch, Intelligent Key or door key cylinder.

Turn ignition switch “ON” or “ACC” position.

CANCELING THE ALARM OPERATION OF THE VEHICLE SECURITY SYSTEM

When unlocking the all doors with the door request switch, Intelligent Key or door key cylinder switch the alarm
operation is canceled.

ACTIVATING THE ALARM OPERATION OF THE VEHICLE SECURITY SYSTEM

Check that the system is in the armed phase. (The security indicator lamp blinks every 2.4 seconds.)
When the following operation 1 or 2 is performed, the system sounds the horns and flashes the headlamps for
about 50 seconds.

Back door or any door is opened during armed phase.

vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN H-line, CAN L-line) allowing a high rate of information transmission with less
