C1-C6:






C7-C10:






Normal Operation
The smart junction box (SJB) monitors the hood switch on circuit 1711 (VT/OG). When an unauthorized intrusion to the engine compartment occurs, the hood switch removes the ground from circuit 1205 (BK), and the SJB activates the vehicle alarm.

The SJB monitors the luggage compartment lid switch on circuit 700 (WH/VT). When an unauthorized intrusion to the luggage compartment occurs, the luggage compartment lid switch completes the circuit to 1205 (BK). The SJB receives a ground signal on circuit 700 (WH/VT) and activates the vehicle alarm.

The SJB monitors the door ajar switches on circuits 1312 (LG/BK) LH front door, 1314 (YE/LG) RH front door, 1742 (VT/OG) LH rear door, and 1754 (RD) RH rear door. When an unauthorized intrusion to the passenger compartment occurs, the door ajar switch completes the circuit to 1205 (BK). The SJB receives a ground signal and activates the vehicle alarm.

The SJB monitors the driver door disarm switch on circuit 1313 (LB/BK). When the driver door lock cylinder is turned to the unlock position, the vehicle alarm is disarmed.

When the SJB activates the vehicle alarm, the horn is sounded, and the parking lamps are flashed.

- circuit 1205 (BK) open
- circuit 1313 (LB/BK) open or short to ground
- circuit 1711 (VT/OG) open or short to ground
- driver door disarm switch
