Normal Operation
The smart junction box (SJB) arms the alarm (after 20 seconds have elapsed) when a lock signal is received from the remote keyless entry (RKE) transmitter, the keyless entry keypad, or the door lock control switch (with the door open, then closed). The SJB disarms the alarm when an unlock signal is received from the RKE transmitter, the keyless entry keypad, the driver door disarm switch or if the ignition key is turned to the ON position.

With the anti-theft perimeter alarm system armed, the SJB monitors the door ajar switches on circuits 1312 (LG/BK) (LH front door), 1314 (YE/LG) (RH front door), 1754 (RD) or 1742 (VT/LG) (LH rear door), and 1754 (RD) (RH rear door). When an unauthorized intrusion to the passenger compartment occurs, the applicable door ajar switch completes the circuit to ground through circuit 1205 (BK). The SJB receives this 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 unlock, the driver door disarm switch completes the ground through circuit 1205 (BK). This signals the SJB to cancel the alarm function.

The 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/liftgate ajar switch on circuit 700 (WH/VT). When an unauthorized intrusion to the luggage compartment occurs, the luggage compartment lid ajar switch opens, removing the ground through circuit 1205 (BK). The SJB receives an open to ground signal on circuit 700 (WH/VT) and activates the vehicle alarm.

When the SJB activates the vehicle alarm, the horn activates on/off repeatedly, and the parking lamps flash on/off repeatedly.

DTC B1334 - sets when circuit 700 (WH/VT) may be shorted to ground or the luggage compartment lid/liftgate ajar switch may be the cause of the short to ground.

DTC B1520 - sets when circuits 1711 (VT/OG) or 1205 (BK) may be open or the hood switch itself may be the cause of the open circuit.

DTC B2116 - sets when circuit 1313 (LB/BK) may be shorted to ground or the driver door disarm switch may be shorted internally, closing circuit 1313 (LB/BK) to ground constantly.

Possible Causes
- Circuit 700 (WH/VT) open or short to ground
- Circuit 1205 (BK) open
- Circuit 1313 (LB/BK) open or short to ground
- Circuit 1711 (VT/OG) open or short to ground
- Door ajar switch
- Driver door disarm switch
- Hood switch
- Luggage compartment lid/liftgate ajar switch
- RKE transmitter
- Keyless entry keypad
- SJB
