Automatic Door Locks Enabled/Disabled

If using scan tool to enable or disable automatic door locks, follow scan tool manufacturer's instructions. If scan tool is not available, close all doors. Place ignition switch in OFF position for at least 20 seconds. Cycle ignition switch from OFF to RUN position 4 times without cranking engine. Malfunction Indicator Light (MIL) should come on each time ignition switch is in RUN position. Using power door lock switch, lock doors. A single chime should sound to indicate that feature has been changed successfully.
