Antitheft and Alarm Systems: Description and Operation

How the Circuit Works

The security system control unit has a 3 position switch: Manual, Auto, and Auto Lock. Here's what happens when you arm the system, regardless of the switch position:
- The parking lights will flash once.
- The security indicator will flash once per second after the system is armed.

Arming the Security System
With the switch in the Manual position, the security system can only be armed by using the remote control transmitter. After you remove the key from the ignition and close all doors, the hood (if equipped with the optional hood switch), the hatch or trunk, press the lock button on the transmitter and the system will arm (if the system is in the beep sound mode, the horn will sound once). The doors will automatically lock when the system is armed.

With the switch in the Auto position, the security system will arm itself within about 20 seconds after you turn the engine off, remove the key from the ignition, and close the hatch or trunk, the hood (if equipped with the optional hood switch), or last door. If a door is opened during the 20 seconds exit delay time, the timer will reset itself. The remote control transmitter can still be used to arm the system with the switch in Auto position (see manual for details).

With the switch in Auto Lock position, the security system will arm itself and lock the doors about 20 seconds after you turn the engine off, remove the key from the ignition, and close the hatch or trunk, the hood (if equipped with the optional hood switch), or last door. If a door is opened during the 20 seconds exit delay time, the timer will reset. The remote control transmitter can still be used to arm the system in the Auto Lock position.

Triggering the Alarm
After the security system is armed, the sound of breaking glass or the opening of a door, hood, hatch or trunk will trigger the alarm, and cause the following:
- The horn will sound for 30 seconds. The optional siren will sound for 60 seconds.
- The parking lights will flash.
- The security indicator LED will flash twice per second.
- The starter will be disabled.

At the end of the alarm cycle, the system will automatically rearm.

Disarming the Security System
There are two ways to disarm the security system:
- With the transmitter
- With the disarm/valet switch

When the system is disarmed, regardless of the method used, the parking lights will flash two times if the alarm has not been triggered and three times if the alarm has been triggered. To disarm the system with the transmitter, press the unlock button (if the system is in the beep sound mode, the horn will sound two times if the alarm has not been triggered, however, will sound three times if the alarm has been triggered). The driver's door will unlock (pressing the unlock button twice will unlock all doors).

To disarm the security system using the disarm/valet switch, enter the car and turn the ignition switch to ON (II) then press the disarm/valet switch button. If you open the door when the control unit switch is in Auto or Auto Lock, a 20 seconds entry delay will give you time to disarm the system. However, when the system is armed by the transmitter, the entry delay time is changed to zero seconds, and the alarm is triggered as soon as you open the door.

Identifying Tripped Sensors
The system will indicate the sensor which triggered the alarm through the security indicator LED. While sitting inside the vehicle with the key out of the ignition switch, all doors, the hood (if equipped with the optional hood switch), the hatch or trunk must be closed. Press and hold the disarm/valet switch. Press the lock button and then the unlock button of the transmitter. Release the disarm/valet switch. The status LED will blink according to the following code:

Sensors Number of Flashes
Door 1 blink, pause, repeat
Trunk/Hatch 2 blinks, pause, repeat
System Switches 3 blinks, pause, repeat
Glass Breakage 4 blinks, pause, repeat
Hood (Optional) 5 blinks, pause, repeat
