Hey guys when you use a BATTERY MEMORY SAVER does it have to be plugged into the OBD port, or can you supply power into the standard 12 volt ( cigarette lighter) port?
The On-Board Diagnostics II (OBD-II) port is used to access the vehicle's computer for various tasks, such as emissions tests and diagnostics. The OBD-II port is where the Hum System is installed so that the network can communicate with the vehicle directly.

If you aren't getting power at the port (easy to test with your multimeter), the fuse is likely the issue. If you ARE getting power, then options are: Break in the harness between the OBD2 connector and the ECU.
Plug the standard OBD2 connector into the vehicle's port located under the driver's side of the dashboard. Turn on the car to power the scan tool or code reader.
The most common reason for getting no OBD code is simply a blown fuse. Even a fuse dedicated solely to the car's computer diagnostics can blow for no apparent reason. Check your fuses to see if any have gone bad. Remember that your car or truck might have more than one fuse box.
