OBDII Has NO Power

pins looks ok but has no power
My OBDII scanner won't light up. I checked pin 16 has no power.
Checked the fuse #58 in the trunk has power: https://www.benzworld.org/threads/r3...ation.3087100/
In fact, I checked all fuses in the trunk only #49 has no power, all the rest have.
Battery just changed by myself, bought from dealer. OBDII has no power before battery was replaced, I thought was not enough voltage. Cigarette light port works fine.
Anyone has the wire diagram for this car? 2013 R350 BlueTec.
Thanks
