Security Functions

Security functions

In addition to monitoring the door and trunk switches, and shook sensing, the security system has a number of other features.

Passive arming (automatic arming)
The security system will automatically arm if the vehicle is left with the ignition off and the doors and trunk closed for more than 30 seconds. The doors will not lock when the system passively arms. To disarm a passively armed vehicle requires that the transmitter be pressed or the ignition switched on. Passive arming is a dealer-installed accessory feature.

Alarms and warning tones
The system provides several warnings and alarms:

ERROR TONE The error tone is a high-pitched tone emitted when the transmitter is pressed to arm the system while one or more of the following conditions exist:
^ a door is open; the trunk is open
^ the ignition is on
^ the driver's door has not been closed since the ignition was switched off.

VALET REMINDER TONES With the valet switch in the ON position, four alternating tones (low - high - low - high) are sounded when the doors are opened or the transmitter is pressed.

WARN AWAY A low-pitched warning tone sounds for 2 seconds if the shock sensor detects a jarring motion. The full alarm is triggered if there are three warn away signals within a 15-second period.

ESCALATING RESPONSE An alternating tone that starts at low volume and builds over a 1 0-second period to the full alarm if the system is not disarmed by pressing the transmitter.

AUDIBLE TICKING A ticking tone that has a 15-second duration is the equivalent to the escalating response when the system has been passively armed. If the system is not disarmed during this 15-second period, the system will activate the full alarm.

FULL ALARM The full alarm is the combined audible and visual alarm that will last for 2 minutes unless turned off with the transmitter.

Anti-scan
If the system receives more than 10 different RF transmissions within a short period of time (approximately one minute), the security system will not disarm for approximately one hour. This feature prevents defeat of the system by thieves employing frequency scan.

Battery back-up
If the vehicle battery is disconnected with the security system armed, the alarm will sound using the back-up battery as its power source. This alarm can also occur if the vehicle battery is completely discharged. The alarm will continue until the vehicle battery is reconnected and the system is disarmed by pressing the transmitter. The back-up battery is charged during the time the ignition is ON.

Low voltage vehicle battery
If the vehicle battery is in a low state of charge, the security system may not disarm when the transmitter is pressed. If, after the vehicle is jump started, the sounder chirps at a rate of once per second, the system must be recoded for each transmitter. Refer to "Coding for new transmitters".

LED history readout
After the alarm has been triggered and has stopped, the LED will show groups of flashes rather than the normal one-per-second. When the system is disarmed, two chirps will be followed by a pause and then a third chirp. The LED flash groups indicate the type of security violation that has occurred:

FLASHES
PER GROUP VIOLATION
2 or 3 door opened
4 shock sensor triggered
5 anti-scan violation
7 trunk opened or valet switch turned ON
8 ignition switched ON


The history memory is cleared when the system is disarmed and the ignition is switched to position I.
