Test A: A Single/More Than One Door Lock Is Inoperative

PINPOINT TEST A: A SINGLE/MORE THAN ONE DOOR LOCK IS INOPERATIVE

Normal Operation
When the vehicle security module (VSM) receives a lock request from the door lock control switch, the VSM provides voltage to the door lock actuators through circuit 117 (PK/BK). Ground for the LH front door actuator is provided through circuit 163 (RD/OG) and ground for the remaining door lock actuators is provided through circuit 118 (PK/OG). When the VSM receives an unlock request, voltage and ground are reversed on the previously listed circuits.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Door lock actuator
- VSM
