Normal Operation
The smart junction box (SJB) receives an unlock signal from the anti-theft inhibit switch through circuit 1313 (LB/BK) by using the ground through circuit 1205 (BK), and turns off the anti-theft perimeter alarm. The SJB monitors the key-in-ignition switch and does not allow the perimeter anti-theft feature to arm until after the key is removed from the ignition switch and 20 seconds have elapsed after locking the vehicle. After all of these criteria have been met, the anti-theft feature will arm any closure that is in its default state.

The SJB monitors the door ajar switches on circuits 1312 (LG/BK) (LF) and 1314 (YE/LG) (RF) to prevent the alarm from being armed while the door(s) is open. If the SJB does not receive a ground signal on circuits 1312 (LG/BK) and 1314 (YE/LG), the SJB will not arm the doors. The door ajar switches are grounded by circuit 1205 (BK).

The SJB monitors the hood ajar switch on circuit 1304 (VT/OG) to prevent the hood from being armed while the hood is open. If the SJB does not receive a ground signal on circuit 1304 (VT/OG), the SJB will not arm the hood. The hood ajar switch is grounded by circuit 1205 (BK).

The SJB monitors the liftgate ajar switch on circuit 1351 (TN) to prevent the liftgate from being armed while the liftgate is open. If the SJB does not receive a ground signal on circuit 1351 (TN), the SJB will not arm the liftgate. The liftgate ajar switch is grounded by circuit 1205 (BK).

The SJB monitors the sliding door ajar switches on circuits 1230 (LG/OG) (LH and RH power sliding doors), 1432 (WH/VT) (LH manual), and 1433 (DB/LG) (RH manual) and all are grounded by circuit 1205 (BK). If the SJB does not receive a ground signal on these circuits, the SJB will not arm the sliding doors.

The SJB receives arm/disarm commands from the remote keyless entry (RKE) transmitter. The SJB then arms/disarms the perimeter alarm system.

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.

DTC B1519 - sets when circuit 1304 (VT/OG) is open, shorted to ground or voltage or if circuit 1205 (BK) is open. The hood switch may also be open or shorted internally.

DTC B1833 - sets when circuit 1313 (LB/BK) is shorted to ground. The anti-theft inhibit switch may also be shorted internally.
