Normal Operation
The passenger door lock control switch supplies a ground signal through circuit 1205 (BK) to the SJB when the LOCK or UNLOCK switch is pressed. When the SJB receives ground through circuit 1296 (OG/BK), the SJB locks the doors by operating the SJB door lock relay (part of SJB). When the SJB receives ground through circuit 1297 (YE/RD), the SJB unlocks the doors by operating the SJB driver door unlock relay (part of SJB) and the SJB passenger door unlock relay (part of SJB).
