I can't look at vehicle specifics right now, but in most cases, the battery positive feed for the OBD2 connector is on the same fuse as the power ports (or, as they used to be known, cigarette lighters).
Check your owners manual for location on interior fuse panel - sometimes they're hidden in funny places.

There is not an interior fuse box, did you double check fuse M30?

1) The scanner will not power on.
2) The scanner will power on but will not read codes.
If it's the second, it's a separate issue from power supply. You'd want to be looking at the data circuit between the OBD2 port and the PCM.

I didn't read this closely enough the first time - which one do you mean:
1) The scanner will not power on.
2) The scanner will power on but will not read codes.
