For the Power Door Lock circuit diagram (Refer to 8 - ELECTRICAL/POWER LOCKS - SCHEMATICS AND DIAGRAMS).

For a complete wiring diagram Refer to Section 8W.

• When Monitored:

Whenever the instrument cluster is awake.

• Set Condition:

The instrument cluster monitors the door lock output circuits and when one of them is shorted to ground or to voltage, this code will set. This code will only set when the door locks are actuated.
