Hi all, 2008 LX-P 5 SPD unknown mileage

When I connect my scanner tool, there's no power. Does anyone know where the fuse is located for the connector? I looked at fuse diagrams and I did find one that states it's a slot 15 - 10A fuse under the hood. I looked and there's no fuse. So, I decided to run over to Advance Auto to buy a fuse. The attendant looked it up and said there's no fuse for that location. It's supposed to be empty she said. She also said slot 15 is a backup fuse. I checked again and number 15 shows below.. I assume DLC means Data Link Connector. Can someone confirm this?
Thanks in advance!

15 BACK UP10A

Audio Unit, Audio-HVAC Sub Display Unit, DLC, Driver's Door Courtesy Light (4-door), Driver's MICU, Front Passenger's Door Courtesy Light (4- door), Fuse 5 in Passenger's Under-dash Fuse/Relay Box, Gauge Control Module, HandsFreeLink Control Unit (Navigation), Immobilizer-Keyless Control Unit, Microphone (Navigation), Navigation Display Unit (Navigation), Navigation Unit (Navigation), Passenger's MICU, Power Window Master Switch

 

I thought he accessory fuse ran the OBD. I'll have to look it up.

 

I greatly appreciate your help.
Thanks!
