PRINCIPLES OF OPERATION - PERIMETER ALARM

The smart junction box (SJB) monitors the door ajar switches circuits 1314 (YE/LG), 1312 (LG/BK), the anti-theft hood switch circuit 1711 (PK/OG), the luggage compartment lid ajar switch circuit 1350 (TN), and the intrusion and inclination sensor circuit 340 (RD/LB).

If any intrusion is detected without the alarm being shut off, the SJB energizes circuit 1324 (BK/LG) sounding the anti-theft alarm horn and the traffic horn while causing the turn signal lamps to flash.

The system can be disarmed by opening the driver door with the key, grounding circuit 1313 (LB/BK) through the door disarm switch, unlocking the doors with the RKE transmitter, or turning the ignition switch to the ON position with a valid key.

The system arms when the driver door is locked with the key (no intrusion or inclination protection), the doors are locked with the remote keyless entry (RKE) transmitter, or the doors are locked with the door lock control switch and then the doors are closed. The SJB monitors the status of all entry points. If any entry point is open, the alarm arms excluding inputs from the open entry point. The SJB adds the entry point to the protected status when the closure of the open entry point is detected.

NOTE: The intrusion sensing feature is not activated if either door or the convertible top (if equipped) is open when the vehicle is armed.

The SJB inhibits the intrusion and inclination sensor and the luggage compartment lid ajar inputs if the luggage compartment lid is opened with a key or the RKE transmitter. Once the luggage compartment lid is closed the intrusion and inclination sensor and the luggage compartment lid ajar switch are monitored by the SJB.
