Normal Operation
The door lock control switches supply a ground signal to the vehicle security module. When the vehicle security module receives ground through circuit 119 (PK/YE), it 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), it 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 liftgate door 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, shorted to battery or ground
- circuit 120 (PK/LG) open, shorted to battery or ground
- circuit 163 (RD/OG) shorted to ground or open
- circuit 456 (DG/OG) open
- circuit 1205 (BK) open
- door lock control switches
- liftgate door lock control switch
- door lock actuator
- vehicle security module
- liftgate remote control
