Vehicle Security (Theft Warning) System

System Description

DESCRIPTION
1. Setting the theft warning system Disarmed phase
When the vehicle is being driven or when doors or trunk lid is open, the vehicle security 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 hood, trunk lid and all doors are closed and locked by key or multi-remote controller. (The security indicator lamp illuminates for 30 seconds.) After about 30 seconds, the system automatically shifts into the "armed" phase (the system is set).

2. Canceling the set theft warning system
When the following (a) or (b) operation is performed, the armed phase is canceled.
a. Unlock the doors with the key or multi-remote controller.
b. Open the trunk lid with the key or multi-remote controller. When the trunk lid is closed after opening the trunk lid with the key or multi-remote controller, the system returns to the armed phase.

3. Activating the alarm operation of the vehicle security system
Make sure the system is in the armed phase.
When the following operation (a), (b) or (c) is performed, the system sounds the horns and flashes the head- lamps for about 50 seconds.
a. Engine hood or any door is opened before unlocking door with key or multi-remote controller.
b. Door is unlocked without using key or multi-remote controller.
c. Trunk lid is opened without using key or multi-remote controller.

POWER SUPPLY
Power is supplied at all times
- through 10 A fuse [No. [28], located in the fuse block (J/B)]
- to security indicator lamp terminal (1).

Power is supplied at all times
- through 7.5 A fuse [No. [14], located in the fuse block (J/B)]
- to BCM terminal (105).

With the ignition switch in the ACC or ON position, power is supplied
- through 7.5 A fuse [No. [23], located in the fuse block (J/B)]
- to BCM terminal ((60).

With the ignition switch in the ON position, power is supplied
- through 7.5 A fuse [No. [32], located in the fuse block (J/B)]
- to BCM terminal (68).

BCM is connected to LCU01, LCU02, LCU03 and LCU04 as DATA LINE A-1 or A-2.

INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors, hood and trunk lid.
To activate the vehicle security system, BCM must receive signals indicating the doors, hood and trunk lid are closed and the doors are locked.
When a door is open, BCM terminal (28), (32), (33) or (37) receives a ground signal from each door switch. When a door is unlocked, each door LCU terminal (5) receives a ground signal from terminal 02 of each door unlock sensor.

When the hood is open, BCM terminal (2) receives a ground signal
- from terminal (1) of the hood switch
- through body grounds (E22) and (E36).

When the trunk lid is open, BCM terminal (20) receives a ground signal
- from terminal (1) of the trunk room lamp switch
- through body grounds (T12), (B22) and (B35).

When the doors are locked with key or multi-remote controller and none of the described conditions exist, the vehicle security system will automatically shift to armed phase.

VEHICLE SECURITY SYSTEM ACTIVATION (With key or remote controller used to lock doors)
If the key is used to lock doors, LCU01 or LCU02 terminal (1) receives a ground signal
- from terminal (3) of the front door key cylinder switch (Driver side) or
- from terminal (1) of the front door key cylinder switch (Passenger side)
- through body grounds (M14) and (M47)

If this signal or lock signal from remote controller is received by BCM, the vehicle security system will activate automatically.
Once the vehicle security system has been activated, BCM terminal (65) supplies ground to terminal (2) of the security indicator lamp.
The security lamp will illuminate for approximately 30 seconds and then blink. Now the vehicle security system is in armed phase.

VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
- opening a door
- opening the trunk lid
- opening the hood
- unlocking door without using the key or multi-remote controller.

Once the vehicle security system is in armed phase, if BCM receives a ground signal at terminal (28), (32), (33), (37) (door switch), (19) (trunk room lamp switch) or (20) (hood switch), or LCU receives a ground signal at terminal (5) (door unlock sensor) the vehicle security system will be triggered. The headlamps flash and the horn sounds intermittently.

Power is supplied at all times
- through 7.5 A fuse (No. [14] , located in fuse and fusible link box)
- to vehicle security lamp relay terminal (1) and
- to vehicle security horn relay terminal (1).

When the vehicle security system is triggered, ground is supplied intermittently
- from terminal (15) of BCM
- to vehicle security lamp relay terminal (2) and
- to vehicle security horn relay terminal (2).

The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 2 or 3 minutes but will reactivate if the vehicle is tampered with again.

VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door or the trunk lid must be unlocked with the key or remote controller.
When the key is used to unlock a door, BCM terminal (31) or (27) receives a ground signal
- from terminal (1) of the front door key cylinder switch (Driver side) or
- from terminal (3) of the front door key cylinder switch (Passenger side).

When the key is used to unlock the trunk lid, BCM terminal (29) receives a ground signal from terminal (1) of the trunk lid key cylinder switch.
When the BCM receives either one of these signals or unlock signal from remote controller, the vehicle security system is deactivated. (Disarmed phase)

PANIC ALARM OPERATION
Multi-remote control system may or may not operate vehicle security system (horn and headlamps) as required.
When the multi-remote control system is triggered, ground is supplied intermittently.
- from BCM terminal (15)
- to vehicle security lamp relay terminal (2) and
- to vehicle security horn relay terminal (2).

The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off after 30 seconds or when smart entrance control unit receives any signal
