Normal Operation
The RH front door lock control switch supplies a ground signal through circuit 1205 (BK) to the smart junction box (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 the SJB). When the SJB receives ground through circuit 1297 (YE/RD), the SJB unlocks the doors by operating the SJB LH front door unlock relay (part of the SJB) and the SJB door unlock relay (part of the SJB).

DTC B2474 - sets when an open or short to ground is detected on circuit 1296 (OG/BK).

DTC B2475 - sets when an open or short to ground is detected on circuit 1297 (YE/RD).

- Circuit 1205 (BK) open
