Normal Operation
The door lock control switch supplies a ground signal to the vehicle security module. When the vehicle security module receives ground through circuit 119 (PK/YE), the vehicle security module grounds circuit 163 (RD/OG) and circuit 118 (PK/OG), while energizing circuit 117 (PK/BK) to lock the doors. When the vehicle security module reads ground at circuit 120 (PK/LG), the vehicle security module will ground circuit 117 (PK/BK), while energizing circuit 163 (RD/OG) and circuit 118 (PK/OG), to unlock the doors. The driver door lock control switch, passenger door lock control switch and the cargo lock control switch circuits are spliced together within the wiring harness.

Possible Causes
- vehicle security module DTC B1300 will set if circuit 119 (PK/YE) is shorted to ground
- vehicle security module DTC B1311 will set if circuit 120 (PK/LG) is shorted to ground
- circuit 117 (PK/BK) shorted to ground or open
- circuit 118 (PK/OG) shorted to ground or open
- circuit 119 (PK/YE) open
- circuit 120 (PK/LG) open
- circuit 163 (RD/OG) shorted to ground or open
- circuit 1205 (BK) open
