Keyless Entry/Security Alarm System
System DescriptionSecurity Alarm System
The security alarm system is armed automatically after the doors, hood, and tailgate are closed and locked. For the system to arm, the ignition switch must be off, the key must be removed, and the security control unit must receive signals that the doors, hood, and tailgate 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, the only control unit inputs that are grounded, and have 0 volts, are the driver's door lock knob switch, the audio unit, DVD player, rear controller and screen, and the navigation display. In other words, all of the other switches are open, including the key cylinder switches, and they have about 10 volts. 10 seconds after the doors and tailgate are locked with the key or the lock knob (with the door open), or immediately after the doors are locked with the LOCK button on the remote transmitter, the security system arms, and the security indicator on the door flashes. If the security indicator does not flash, the system is not arming. Check the doors, hood, and tailgate to see if they are closed. A beep to confirm the security alarm system is armed will sound if the LOCK button is pressed a second time within 5 seconds.
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 the system will not arm. Conversely, a switch that is slightly misadjusted can sound an alarm for no apparent reason. In this case, a significant change in outside temperature, the vibration of a passing truck, or someone bumping into the vehicle could cause the alarm to sound. There is no glass breakage or motion detector feature.
If anything is opened or improperly unlocked after the system is armed, the control unit receives a ground signal from that switch, and the 10 volts reference drops to 0 volts. If the audio unit, navigation display, DVD player, or rear controller and screen is disconnected, the input loses its ground, and the input voltage goes to 10 volts. The system sounds the alarm when any of these things occur:
- The ignition switch is turned ON (II).
- A door or tailgate is forced open.
- A door is unlocked without using the key or the remote transmitter.
- The hood is opened.
- The audio unit, navigation display, DVD player, or rear controller and screen is disconnected.
- The panic mode is activated.
When the system sounds the alarm, the horns sound and the exterior lights flash for 2 minutes. The alarm can be stopped at any time by unlocking either door with the key or by pressing any button on the remote transmitter.
Panic Mode
The panic mode allows the security system to sound the alarm with the remote transmitter in order to attract attention. When the PANIC button is pressed and held for 2 seconds, the alarm will sound and the exterior lights will flash for about 30 seconds.
The panic mode can be canceled at anytime by pressing any button on the remote transmitter or by turning the ignition switch ON (II). The panic mode will not function if the ignition switch is ON (II).
