Vehicle Security (Theft Warning) System

System Description




OPERATION FLOW

SETTING THE VEHICLE SECURITY SYSTEM

Initial Condition
1. Close all doors.
2. Close hood and trunk lid.

Disarmed Phase
When the vehicle security system is in the disarmed phase, the security indicator lamp blinks every 2.6 seconds.

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.) After about 30 seconds, the system automatically shifts into the "armed" phase (the system is set). (The security indicator lamp blinks every 2.6 seconds.)

CANCELING THE SET VEHICLE SECURITY 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.

ACTIVATING THE ALARM OPERATION OF THE VEHICLE SECURITY SYSTEM
Make sure the system is in the armed phase. (The security indicator lamp blinks every 2.6 seconds.) When the following operation (a) or (b) is performed, the system sounds the horn and flashes the headlamps for about 2.5 minutes.
a. Engine hood, trunk lid or any door is opened before unlocking door with key or multi-remote controller.
b. Driver's door is unlocked without using key or multi-remote controller.

POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times:
- through 10 A fuse [No. [24], located in the fuse block (J/B)]
- to security indicator lamp terminal (1) and
- to key switch terminal (2).

When the key switch is ON (ignition key is inserted in key cylinder), power is supplied:
- through key switch terminal (1)
- to smart entrance control unit terminal (24).

Power is supplied at all times:
- through 40 A fusible link (letter [d], located in the fuse and fusible link box)
- to circuit breaker-1 terminal (1)
- through circuit breaker-1 terminal (2)
- to smart entrance control unit terminal (1).

With the ignition switch in the ACC or ON position, power is supplied:
- through 10 A fuse [No. [10], located in the fuse block (J/B)]
- to smart entrance control unit terminal (17).

With the ignition switch in the ON or START position, power is supplied:
- through 10 A fuse [No. [8], located in the fuse block (J/B)]
- to smart entrance control unit terminal (11).

Ground is supplied:
- to smart entrance control unit terminal (10)
- through body grounds (M2) and (M61).

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, the smart entrance control unit must receive signals indicating the doors, hood and trunk lid are closed and the driver's door is locked.
When a door is open, smart entrance control unit terminals (15) or (16) receives a ground signal from each door switch.

When a door is unlocked, smart entrance control unit terminal (14) receives a ground signal:
- from terminal (4) of front door door unlock sensor LH
- through terminal (2) of front door door unlock sensor LH
- through body grounds (M2) and (M61) for the front door unlock sensor LH.

When the hood is open, smart entrance control unit terminal (29) receives a ground signal:
- from terminal (1) of the hood switch
- through terminal (2) of the hood switch
- through body grounds (E34) and (E10).

When the trunk lid is open, smart entrance control unit terminal (26) receives a ground signal:
- from terminal (1) of the trunk room lamp switch
- through terminal (2) of the trunk room lamp switch
- through body grounds (T6) and (T9).

When the vehicle security system is in disarmed phase, if one of the described conditions exist, the security indicator lamp will blink every 2.6 seconds.

VEHICLE SECURITY SYSTEM ACTIVATION (With key or remote controller used to lock doors)
If the key is used to lock doors, smart entrance control unit terminal (30) receives a ground signal:
- from terminal (1) of the front door key cylinder switch LH
- through terminal (2) of the front door key cylinder switch LH
- through body grounds (M2) and (M61).

If this signal or lock signal from remote controller is received by the smart entrance control unit, the vehicle security system will activate automatically.

Once the vehicle security system has been activated, smart entrance control unit terminal (33) supplies ground to terminal (2) of the security indicator lamp.
The security indicator lamp will illuminate for approximately 30 seconds and then blink every 2.6 seconds. 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 driver's door without using the key or multi-remote controller.

Once the vehicle security system is in armed phase, if the smart entrance control unit receives a ground signal at terminal (14) (door unlock sensor LH), (15), (16) (door switch), (26) (trunk room lamp switch) or (hood switch), the vehicle security system will be triggered. The headlamps flash and the horns sound intermittently.

Power is supplied at all times:
- through 10 A fuse (No. [41], located in fuse and fusible link box)
- to vehicle security lamp relay terminal (1).

When the vehicle security system is triggered, ground is supplied intermittently:
- from terminal (8) of the smart entrance control unit
- to vehicle security lamp relay terminal (2) and
- to horn relay terminal (1).

The headlamps flash and the horn sound 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, small entrance control unit terminal (31) receives a ground signal:
- from terminal (3) of the front door key cylinder switch LH
- through terminal (2) of the front door key cylinder switch LH
- through body grounds (M2) and (M61).

When the key is used to unlock the trunk lid, smart entrance control unit terminal (27) receives a ground signal:
- from terminal (1) of the trunk lid key cylinder switch
- through terminal (2) of the trunk lid key cylinder switch
- through body grounds (T6) and (T9).

When the smart entrance control unit 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 smart entrance control unit terminal (8)
- to vehicle security lamp relay terminal (2) and
- to horn relay terminal (1).

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 from multi-remote controller.
