The door lock control switches receive voltage from the central junction box (CJB) fuse 102 (30A) on circuit 116 (RD/BK).

When LOCK is pressed on the driver door lock control switch, voltage is supplied to the door lock actuators through circuit 119 (PK/YE), the passenger door lock switch, and circuit 117 (PK/BK). Ground is supplied for the door lock actuators through circuit 118 (PK/OG), the passenger door lock switch, circuit 120 (PK/LG), the driver door lock control switch, and circuit 57 (BK). When UNLOCK is pressed on the driver door lock control switch, voltage is supplied to the door lock actuators through circuit 120 (PK/LG), the passenger door lock switch, and circuit 118 (PK/OG). Ground is supplied for the door lock actuators through circuit 117 (PK/BK), the passenger door lock switch, circuit 119 (PK/YE), the driver door lock control switch, and circuit 57 (BK).
