Normal Operation
The door lock control switches are grounded on circuit 1205 (BK). The door lock control switches supply a ground signal to the smart junction box (SJB). When the SJB receives a door lock control switch 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, it supplies voltage to the door lock actuators through circuits 1328 (RD/OG) and 1383 (RD) while grounding circuits 1329 (YE) and 1384 (LB) to lock all the doors. When the SJB receives a door lock control switch unlock command through circuits 1317 (DB/LG) from the driver door lock control switch, or circuit 1297 (YE/RD) from the passenger door lock control switch, it supplies voltage to the door lock actuators through circuits 1329 (YE) and 1384 (LB) while grounding circuits 1328 (RD/OG) and 1383 (RD) to unlock all the doors.

The luggage compartment lid release solenoid is grounded on circuit 1205 (BK). When the SJB receives an open command from the remote keyless entry (RKE) transmitter the SJB grounds the luggage compartment lid release relay control circuit 26 (WH/VT). The relay closes and supplies voltage to circuit 1092 (PK/OG) which closes the luggage compartment lid release solenoid, releasing the luggage compartment lid.

Possible Causes
- fuse
- circuit 26 (WH/VT) open
- circuit 1092 (PK/OG) open
- circuit 1205 (BK) open
- circuit 1328 (RD/OG) open or short to ground
- circuit 1329 (YE) open or short to ground
- circuit 1383 (RD) open or short to ground
- circuit 1384 (LB) open or short to ground
- RKE transmitter
- bussed electrical center (BEC)
- door lock actuator
- luggage compartment lid latch
- luggage compartment lid release solenoid (part of the luggage compartment lid latch)
- luggage compartment lid release relay
- SJB
