Antitheft and Alarm Systems: Description and Operation

OPERATION FLOW

SETTING THE THEFT WARNING SYSTEM
Initial condition
1. Close all doors.
2. Close hood and trunk lid.

Disarmed phase
The theft warning system is in the disarmed phase when any door(s), hood or trunk lid is opened. The security indicator lamp blinks every second.

Pre-armed phase and armed phase
The theft warning 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.)

CANCELLING 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. When the trunk lid is closed after opening the trunk lid with the key, the system returns to the armed phase.

ACTIVATING THE ALARM OPERATION OF THE THEFT WARNING 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 horns and flashes the headlamps for about 2.5 minutes. (At the same time, the system disconnects the starting system circuit.)
a. Engine hood, trunk lid 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.


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)
^ 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. [B], 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 (M62).

INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the theft warning system is controlled by the doors, hood and trunk lid.
To activate the theft warning system, the smart entrance control unit must receive signals indicating the doors, hood and trunk lid are closed and the doors are locked.
When a door is open, smart entrance control unit terminals (15), (16) or (35) receives a ground signal from each door switch.
When a door is unlocked, smart entrance control unit terminals (12), (13) or (14) receives a ground signal:
^ from terminal (4) of each door unlock sensor
^ through terminal (2) of each door unlock sensor
^ through body grounds (M2) and (M62) for the front door unlock sensors LH or RH and rear door unlock sensor RH
^ through body grounds (B13) and (B19) for the rear 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 theft warning system is in disarmed phase,
if one of the described conditions exist, the theft warning indicator will blink every second.

THEFT WARNING 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
^ from terminal (3) of the front door key cylinder switch RH
^ through terminal (2) of the front door key cylinder switch LH or RH
^ through body grounds (M2) and (M62).
If this signal or lock signal from remote controller is received by the smart entrance control unit, the theft warning system will activate automatically.

Once the theft warning system has been activated, smart entrance control unit terminal (33) supplies ground to terminal (2) of the security indicator lamp.

The security lamp will illuminate for approximately 30 seconds and then blink every 2.6 seconds. Now the theft warning system is in armed phase.

THEFT WARNING SYSTEM ALARM OPERATION
The theft warning 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 theft warning system is in armed phase, if the smart entrance control unit receives a ground signal at terminal (12), (13), (14) (door unlock sensor), (15), (16), (35) (door switch), (26) (trunk room lamp switch) or (29) (hood switch), the theft warning system will be triggered. The headlamps flash and the horns sound intermittently, and the starting system is interrupted.
With the IGN SW in ON or START position, power is supplied:
^ through 10 A fuse [No. 25, located in the fuse block (J/B)].
^ to theft warning relay terminal (1).

If the theft warning system is triggered, ground is supplied:
^ from terminal (32) of the smart entrance control unit
^ to theft warning relay terminal (2).

With power and ground supplied, power to the clutch interlock relay (M/T models) or Park/neutral position (PNP) relay (A/T models) is interrupted. The starter motor will not crank and the engine will not start. Power is supplied at all times:
^ through 10 A fuse (No. 41, located in fuse and fusible link box)
^ to theft warning lamp relay terminal (1) and
^ to theft warning horn relay terminal (1)

When the theft warning system is triggered, ground is supplied intermittently:
^ from terminal (8) of the smart entrance control unit
^ to theft warning lamp relay terminal (2) and
^ to theft warning horn relay terminal (2).
The headlamps flash and the horns sound intermittently.
The alarm automatically turns off after 2 or 3 minutes but will reactivate if the vehicle is tampered with again.

THEFT WARNING SYSTEM DEACTIVATION
To deactivate the theft warning 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, smart entrance control unit terminal (31) receives a ground signal:
^ from terminal (3) of the front door key cylinder switch LH
^ from terminal (1) of the front door key cylinder switch RH
^ through terminal (2) of the front door key cylinder switch LH or RH
^ 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 theft warning system is deactivated.(Disarmed phase)

PANIC ALARM OPERATION
Multi-remote control system may or may not operate theft warning 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 theft warning lamp relay terminal (2) and
^ to theft warning 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 from multi-remote controller.
