INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the theft warning system is controlled by the doors, hood and trunk lid.

Pattern A
To activate the theft warning system, the smart entrance control unit must receive signals indicating the doors, hood and trunk lid are closed.
When a door is open, smart entrance control unit terminal 28 or 29 receives a ground signal from each door switch.
When the hood is open, smart entrance control unit terminal 27 receives a ground signal:
- from terminal + of the hood switch
- through body grounds E7 and E37.
When the trunk lid is open, smart entrance control unit terminal 38 receives a ground signal:
- from terminal + of the trunk room lamp switch
- through body grounds B13 and B19.
When smart entrance control unit receives LOCK signal from key cylinder switch or multi-remote controller and none of the described conditions exist, the theft warning system will automatically shift to armed mode.

Pattern B
To activate the theft warning system, the smart entrance control unit must receive signal indicating any door (including hood and trunk lid) is opened.
When the front doors are locked with key, lock/unlock switch or multi-remote controller and then all doors are closed, the theft warning system will automatically shift to armed mode.

THEFT WARNING SYSTEM ACTIVATION

Pattern A
With all doors closed (including hood and trunk lid), if the key is used to lock doors, smart entrance control unit terminal 41 receives a ground signal:
- from terminal L of the key cylinder switch LH or key cylinder switch RH
- through body grounds M28 and M54.
If this signal, or lock signal from remote controller is received by the smart entrance control unit, the theft warning system will activate automatically.


NOTE: Theft warning system can be set even though all doors are not locked.

Pattern B
With any door open, if lock/unlock switch is used to lock doors, smart entrance control unit terminal 23 receives a ground signal:
- from terminal 14 of main power window and door lock/unlock switch, or
- from terminal 1 of door lock/unlock switch RH
- through body grounds M28 and M54, or
With any door open, if the key is used to lock doors, smart entrance control unit terminal 41 receives a ground signal:
- from terminal L of the key cylinder switch LH or key cylinder switch RH
- through body grounds M28 and M54.
If these signals and lock signal from remote controller are received by the smart entrance control unit and ground signals of terminals 36 and 37 are interrupted (both front doors locked), the theft warning system will activate automatically.


NOTE: Theft warning system can be set even though the rear door is not locked.

Once the theft warning system has been activated, smart entrance control unit terminal 31 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 hood or the trunk lid.
- detection of battery disconnect and connect.
Once the theft warning system is in armed phase, if the smart entrance control unit receives a ground signal at terminal 28 or 29 (door switch), 38 (trunk room lamp switch) or 27 (hood switch), the theft warning system will be triggered. The headlamps flash and the horn sounds intermittently.

Power is supplied at all times:
- through 15 A fuse (No. 39, located in fuse and fusible link box)
- to theft warning lamp relay terminal 3,
- through 15 A fuse (No. 40, located in fuse and fusible link box)
- to theft warning lamp relay terminal 6
- through 10 A fuse (No, 35 located in fuse and fusible link box)
- to theft warning lamp relay terminal 1 and
- to theft warning horn relay terminals 1 and 6
- through 10 A fuse (No. 33, located in fuse and fusible link box)
- to horn relay terminal 2.
When the theft warning system is triggered, ground is supplied intermittently:
- from smart entrance control unit terminal 4
- to theft warning horn relay terminal 2 and
- to theft warning lamp relay terminal 2.
When theft warning horn relay is energized, ground is supplied intermittently:
- to horn relay terminal 1,
- through body grounds E7 and E37.
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after about 50 seconds but will reactivate if the vehicle is tampered with again.

THEFT WARNING SYSTEM DEACTIVATION
To deactivate the theft warning system, a door or trunk lid must be unlocked with the key or remote controller.
When the key is used to unlock the door, smart entrance control unit terminal 30 receives a ground signal:
- from terminal U of front door key cylinder switch LH or front door key cylinder switch RH
When the key is used to open the trunk lid, smart entrance control unit terminal 42 receives a ground signal
from terminal + of the trunk lid key cylinder switch (unlock switch).
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
When the multi-remote control system (panic alarm) is triggered, ground is supplied intermittently:
- from smart entrance control unit terminal 4
- 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 25 seconds or when smart entrance control unit receives any signal from multi-remote controller.
