Description And Operation: Anti-Theft

The perimeter anti-theft system consists of the following:

• Door ajar switches
• Door disarm switch
• Door lock control switch
• Hood ajar switch
• Horn
• Liftgate ajar switch
• Remote keyless entry (RKE) transmitter
• Keyless entry keypad
• Turn signal lamps
• Smart junction box (SJB)

The perimeter anti-theft feature is controlled by the SJB. The alarm can be armed by:

• pressing the LOCK button on the RKE transmitter.
• pressing the door lock control switch to LOCK with the accompanying door open.
• pressing the 7/8 and 9/0 buttons on the keyless entry keypad simultaneously.

The SJB monitors all of the inputs (all doors, hood, liftgate must be closed and the key must be out of the ignition switch) and 20 seconds after all of the inputs are closed, arms the perimeter alarm. From the time each individual input is closed, to the time the perimeter alarm is armed for that particular input, is the "pre-arm phase". The pre-arm phase is separate for each individual input. If the door lock control switch was pressed to LOCK with the accompanying door open, all of the inputs that are closed (hood, liftgate, other doors) would immediately begin their pre-arm phase. After the door (that was open) is closed, it will begin its pre-arm phase. The perimeter alarm would arm in stages, in relation to which input was closed first after the arming command was given. In the event of an unauthorized entry, the alarm will be activated by the SJB. When the alarm is activated, the SJB intermittently grounds the horn relay, causing the horn to sound in regular intervals, and intermittently sends voltage to the turn signals, causing the turn signal lamps to flash in regular intervals.

The perimeter alarm can be disarmed only by:

• pressing the UNLOCK button on the RKE transmitter.
• turning the door lock cylinder to the UNLOCK position.
• using a valid programmed key to turn the ignition switch to the ON position.
• entering the correct vehicle unlock code on the keyless entry keypad.

The perimeter alarm can be deactivated (not disarmed), by pressing the PANIC button on the RKE transmitter. This action will not disarm the alarm, but will stop the alarm from activation (horn sounding and turn signals flashing). The perimeter alarm will continue to be armed.
