Hi,
The data link connector (DLC) is powered by the HVAC control/ignition fuse in the body control module.
I attached three pics below. Pic 1 indicates the connectors to check:
Pin16 for battery power
Pins 4 and 5 for ground.
Pic 2 is the schematic to the connector
Pic 3 shows the fuse location.
When you check the fuse, make sure there is power to and from it. Note: It should have power at all times.

Let me know what you find.
Take care,
