Antitheft and Alarm Systems: Description and Operation
FUNCTION AND OPERATION(1) The security system monitors the dome and trunk light circuits to sense unauthorized entry into the vehicle. The system senses impacts to the vehicle resulting from possible suspicious activity. The system will sound the horn and flash the parking lights if entry or impact is detected. When actively armed, the system will disable the starter. The starter circuit is deactivated through a relay which interrupts the circuit.
(2) The remote transmitter arms or disarms the system. The remote arm and disarm also provides driver convenience of locking and unlocking the doors. The security system communicates with the door lock time unit to lock and unlock the doors. When disarming, the system turns on the dome light illuminating the interior for entering the vehicle in the dark.
(1) Passive Arming
The system arms automatically 27 seconds after the dome light dims off. If a door or the trunk is opened within the 27 second exit delay, the system waits until all doors and trunk are closed to begin a new 27 second cycle.
Note: The doors will not lock automatically when the system arms.
2) Passive Disarming
The system can be disarmed by turning the ignition switch to the ON position. When a door is opened the parking lights flash and a clicking noise is heard counting down the 17 second entry delay before the alarm sound.
3) Active Arming
The system arms/disarms when the remote transmitter button is pressed. Along with the arm/disarm signal, the doors lock/unlock. The doors and trunk must be closed securely and the parking lights switched OFF for the system to arm
4) Active Disarming
The system disarms when the remote transmitter button is pressed. The transmitter also disarms the system for passively armed. The doors automatically unlock with the disarm signal.
5) Alarm Activation
The alarm sounds if the doors or trunk are opened after the system is armed. A sudden shock such as breaking a window or not disarming the system before the end of the 17 second entry delay also sets off the alarm.
6) Alarm
The alarm sounds for 2 minutes. The system rearms if all sensors are returned to a normal state. If the sensors are rot returned to a normal state, the alarm continues to sound in 2 minute cycles to a total of 1O minutes.
7) Starter Interrupt
Withe the system actively armed, the system disables the starter circuit. The starter will not operate unless the system is disarmed actively.
Note:The system must be disarmed with the remote transmitter if armed with the remote transmitter for the engine to start.
8) Emergency By-Pass
If the remote transmitter is lost or broken the starter interrupt can be by-passed allowing the engine to start. The following procedure must be used to activate the emergency by-pass.
1. Enter the vehicle.
Note:The alarm will sound as the door is opened.
2. Securely close the door. Do not change the position of the Security Switch or have the doors or trunk open, otherwise the alarm will sound for 10 minutes before the engine can be started.
3. Turn on the parking lights. The alarm will sound for two minutes.
4. Start the engine by turning the ignition switch.
5. Turn off the parking light switch.
9) Red Indicator Light
The red indicator light signals the status of the system. Under normal conditions the light will flash approximately every two seconds. If an intrusion has been sensed and the alarm was activated the indicator light will flash a code showing the type of intrusion as follows:
Number of Flashes Point of Intrusion
2 = Door
4 = Shock Sensor Activated
5 = Use of non-authorized remote transmitter.
8 = Ignition tampering
(10) Panic Mode
The security system will automatically sound the alarm if the remote transmitter button is held down for more than 3 seconds. To deactivate the panic mode hold the button for 8 seconds or turn the ignition switch to the on
(11) Warn Away
Minor impacts or shocks to the vehicle will cause the system to sound the horn as a warning. If 3 minor shocks are sensed within 7 seconds then the alarm will sound a normal 2 minute alarm cycle.
(12) Horn Signal
The horn provides feedback for the driver that the system responded to the remote transmitter. The horn will sound a single tone when armed and two tones when disarmed. A third tone will sound indicating the alarm was activated.
