Normal Operation
The smart junction box (SJB) receives a lock/unlock signal from the door disarm switch (part of the driver door latch) through circuits 1317 (DB/LG) and 1316 (WH/VT) by using the ground through circuit 570 (BK/WH), and depending on the signal, either disarms the anti-theft perimeter alarm, or arms the anti-theft perimeter alarm (if all of the criteria have been met). 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, all doors, hood, liftgate and liftgate glass are closed, and 20 seconds have elapsed after locking the vehicle. After all of these criteria have been met, the anti-theft feature will arm.
The SJB monitors the hood switch on circuit 1304 (VT/OG) to prevent the alarm from being armed while the hood is open. If the SJB does not see a ground signal on circuit 1304 (VT/OG), the SJB will not arm the alarm. The hood switch is grounded by circuit 570 (BK/WH).
The SJB monitors the liftgate ajar switch on circuit 701 (LB/BK) and the liftgate glass ajar switch on circuit 700 (WH/VT) to prevent the alarm from being armed while the liftgate glass or the liftgate is/are open. If the SJB does not see a ground signal on circuits 700 (WH/VT) and 701 (LB/BK), the SJB will not arm the alarm. The liftgate glass and liftgate ajar switches are grounded by circuit 570 (BK/WH).
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 also intermittently sends voltage to the turn signals, causing the turn signal lamps to flash in regular intervals.
DTC B1519 - sets during self-test when circuit 1304 (VT/OG) is open, shorted to ground or voltage, or if circuit 570 (BK/WH) is open. The hood switch may also be open or shorted internally.
DTC B2100 - sets when circuits 1316 (WH/VT) or 1317 (DB/LG) are open, shorted to ground or voltage. The door disarm switch may also be open or shorted internally.

- Circuit 1316 (WH/VT) open, short to ground or voltage
- Circuit 1317 (DB/LG) open, short to ground or voltage
- Door disarm switch (part of the driver door latch)
- Driver door lock unit
- Hood switch
- Liftgate glass ajar switch
