INITIAL CONDITION TO ACTIVATE THE SYSTEM
Operation of theft warning system is controlled by doors.
To activate theft warning system, smart entrance control unit must receive signals indicating doors and hood are closed and doors are locked.
When a door is open, smart entrance control unit terminal 9, 24, 34 or 41 receives a ground signal from a door switch or back door latch switches.
When a door is unlocked, smart entrance control unit terminal 37, 40, 46 or 48 receives a ground signal from front door lock actuator LH or RH (door unlock sensor) terminal 4 or from back door lock actuator (door unlock sensor) terminal 4 or from sliding door lock actuator LH or RH (door unlock sensor) terminal 4.
When hood is open, smart entrance control unit terminal 31 receives a ground signal
- from hood switch terminal 1
- through body grounds E3, E30 and E50.

When back door is open, smart entrance control unit terminal 24 receives a ground signal
- from back door latch switch LH and RH terminal 1
- through body ground D204.

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

THEFT WARNING SYSTEM ACTIVATION (WITH KEY OR REMOTE CONTROLLER USED TO LOCK DOORS)
If key is used to lock doors, smart entrance control unit terminal 19 receives a ground signal
- from front door key cylinder switch LH terminal 2
- from front door key cylinder switch RH terminal 1
- through body grounds M68, M105 and M130
- from back door key cylinder switch terminal 2
- through body ground D204.

If this signal or lock signal from remote controller is received by smart entrance control unit, theft warning system will activate automatically.
Once theft warning system has been activated, smart entrance control unit terminal 45 supplies ground to security indicator lamp terminal 2.
Security lamp will illuminate for approximately 30 seconds and then blink.
Theft warning system is now in armed phase.

THEFT WARNING SYSTEM ALARM OPERATION
Theft warning system is triggered by
- opening a door without using key or remote controller
- opening hood
- unlocking door without using key or remote controller
- ACC, ON or START signal without ignition key in ignition key cylinder
- Battery is reconnected after being disconnected while system is in armed phase.

Once theft warning system is in armed phase, if smart entrance control unit receives a ground signal at terminal 37, 40, 46, 48 (door unlock sensor), 9, 24, 34, 41 (door switch), or 31 (hood switch), or power is supplied to smart entrance control unit terminal 36 or 43 without ignition key inserted signal at terminal 35, theft warning system will be triggered. Headlamps flash, horn sounds intermittently, and starting system is interrupted.

Power is supplied at all times
- through 7.5 A fuse (No. 39, located in the fuse and fusible link box)
- to theft warning relay terminal 2

If theft warning system is triggered, ground is supplied
- from smart entrance control unit terminal 28
- to theft warning relay terminal 1.

With power and ground supplied, starter motor circuit is interrupted. Starter motor will not crank and engine will not start.

Power is supplied at all times
- through 15 A fuse (No. 42, located in fuse and fusible link box)
- to horn relay terminals 2 and 3, and
- to tail lamp relay terminals 2 and 3.

When theft warning system is triggered, ground is supplied intermittently
- from smart entrance control unit terminal 21
- to horn relay terminals 1 and
- from smart entrance control unit terminal 26
- to tail lamp relay terminal 1.

At this time, alarm signal is sent from smart entrance control unit terminal 29 to headlamp control unit terminal 19.
Headlamps and exterior lamps flash and horn sounds intermittently.
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 theft warning system, a door must be unlocked with key or remote controller.
When key is used to unlock the door, smart entrance control unit terminal 27 receives a ground signal
- from front door key cylinder switch LH terminal 1
- from front door key cylinder switch RH terminal 2
- from back door key cylinder switch terminal 2.

When smart entrance control unit receives one of these signals or unlock signal from remote controller, theft warning system is deactivated (Disarmed phase).
