Normal Operation
The smart junction box (SJB) receives voltage through circuit 37 (YE). Circuit 37 (YE) supplies voltage to the 3 internal SJB door lock relays which are part of the SJB. When the SJB receives a lock or unlock command through a door lock control switch, remote keyless entry (RKE) keypad or RKE transmitter, it activates the door lock actuators accordingly by operating the correct SJB door lock relay(s). To lock the doors the SJB supplies voltage to circuits 1383 (RD), 1385 (LG), 1328 (RD/OG) and 1387 (VT) through the SJB door lock relay and grounds circuits 1384 (LB), 1386 (OG), 1329 (YE) and 1388 (GY) through the SJB LH front door unlock relay or the SJB door unlock relay. To unlock the doors the SJB supplies voltage to circuits 1384 (LB), 1386 (OG), 1329 (YE) and 1388 (GY) through the SJB LH front door unlock relay and door unlock relay, and grounds circuits 1383 (RD), 1385 (LG), 1328 (RD/OG) and 1387 (VT) SJB door lock relay.
Possible Causes

- circuit 1383 (RD) open or short to ground
- circuit 1384 (LB) open or short to ground
- circuit 1385 (LG) open or short to ground
- circuit 1386 (OG) open or short to ground
- circuit 1387 (VT) open or short to ground
- circuit 1388 (GY) open or short to ground
- door lock actuator
- SJB
