throwing codes please help

okay my check engine light came on today
got home scaned it with hp tuners and this is what i came up with
U1000-Class 2 Communication malfunction(history)(immature)
P0300-engine misfire deteced(pending)(immature)
B0022-LF/Driver frontal deployment loop single stage or stage 1 risistance low (history)(immature)
C0046-Brake pressure sensor A/B(history)
C0051-Steering wheel postion sensor(history)

I have reset the codes but they all come back yet the check engine light has gone off. So i am now confused as to what to do?
Should I worry About anything or not I know the p0300 code cannot be good but car seems to be running fine sounds good feels good so now what?

thanks for any help
scan file from drive after i reset codes is below

Okay so i pulled the plugs out to check there condition and everything looks fine not white tipped or anything but i did find one thing on the coil packs there is a fasteners that holds the coil packs in place i did notice that it was in the up postition so i pushed it back closed making sure that the coil pace was in place.

buy the car used?
