Security Alarm System

System Description

Security Alarm System

The security alarm system is armed automatically after the doors, hood, and trunk lid are closed and locked. For the system to arm, the ignition switch must be off and the key removed, and the security control unit must receive signals that the doors, hood, and trunk lid are closed and locked. The alarm can be disarmed at any time by unlocking either door with the key or the remote transmitter.

When everything is closed and locked, none of the control unit inputs are grounded (switches open). Fifteen seconds after the doors are locked with the key, the driver's lock knob, or the remote transmitter, the system arms. The security indicator on the driver's door panel flashes immediately after everything is closed and locked.

If one of the switches is misadjusted or there is a short in the system, the system will not arm. As long as the control unit continues to receive a ground signal, it senses that the vehicle is not closed and locked, and it will not arm. Conversely, a switch that is slightly misadjusted can sound an alarm for no apparent reason. In this case, it may only take a significant change in outside temperature, the vibration of a passing truck, or someone bumping into the vehicle to make the alarm sound.

If anything is opened or improperly unlocked after the system is armed, the control unit receives a ground signal from that switch. The system sounds the alarm when any of these things occur:

- A door is forced open
- A door is unlocked without using the key or the remote transmitter
- The hood is opened
- The trunk lid is opened without using the remote transmitter
- The audio unit is removed

When the system sound the alarm because of one of these violations, the security horn sounds and the headlight (low beam), parking lights, taillights, and side marker lights flash for 120 seconds. The alarm then shuts off and the system rearms. The alarm can be stopped at any time by unlocking either door with the key or the remote transmitter.

Panic Mode
The panic mode allows the security system to be set off by the remote transmitter to attract attention. When you push and hold the PANIC button for about two seconds, the alarm will sound and the exterior lights will flash for about 30 seconds.
To immediately cancel the panic mode, press any button on the remote transmitter, or turn the ignition switch ON (II). The panic mode will not function if the key is in the ignition switch.
