Normal Operation
The door lock control switches are grounded through circuit 1205 (BK). The door lock control switches supply a ground signal to the smart junction box (SJB) for the lock command through circuit 1316 (WH/VT) from the driver door lock control switch, or circuit 1296 (OG/BK) from the passenger door lock control switch. The door lock control switches supply a ground signal to the SJB for the unlock command through circuit 1317 (DB/LG) from the driver door lock control switch, or circuit 1297 (YE/RD) from the passenger door lock control switch.

When the SJB receives a door lock control switch lock command, the door lock relay is energized, supplying voltage to the door lock actuators through circuits 1328 (RD/OG) and 1383 (RD). The actuators are grounded through circuits 1329 (YE) and 1384 (LB), the SJB and circuit 1205 (BK).

When the SJB receives a door lock control switch unlock command, the driver door unlock and the door unlock relays are energized, supplying voltage to the door lock actuators through circuits 1329 (YE) and 1384 (LB). The actuators are grounded through circuits 1328 (RD/OG) and 1383 (RD), the SJB and circuit 1205 (BK).

DTC B1309 - is an on-demand DTC that sets if the SJB detects a short to ground on the driver door lock switch circuit 1316 (WH/VT).

DTC B1341 - is an on-demand DTC that sets if the SJB detects a short to ground on the driver door unlock switch circuit 1317 (DB/LG).

DTC B2474 - is an on-demand DTC that sets if the SJB detects a short to ground on the passenger door lock switch circuit 1296 (OG/BK).

DTC B2475 - is an on-demand DTC that sets if the SJB detects a short to ground on the passenger door unlock switch circuit 1297 (YE/RD).

Possible Causes
- Circuit 1205 (BK) open
- Circuit 1296 (OG/BK) open, short to ground or voltage
- Circuit 1297 (YE/RD) open, short to ground or voltage
- Circuit 1316 (WH/VT) open, short to ground or voltage
- Circuit 1317 (DB/LG) open, short to ground or voltage
- Door lock control switch(es)
- SJB
