Normal Operation
The SJB receives power through circuit 37 (YE). Circuit 37 (YE) supplies power 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, keyless entry keypad or remote transmitter, it activates the door lock actuators accordingly by operating the correct SJB door lock relay(s). To lock the doors the SJB supplies power 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 driver door unlock relay or the SJB passenger door unlock relay. To unlock the doors the SJB supplies power to circuits 1384 (LB), 1386 (OG), 1329 (YE) and 1388 (GY) through the SJB driver door unlock relay and passenger door unlock relay and grounds circuits 1383 (RD), 1385 (LG), 1328 (RD/OG) and 1387 (VT) SJB door lock relay.
