Hi all, I find myself about to change out the control arm and the vertical assist link that goes somewhat with it on a 2009 Versa 1.8L 6 speed manual. I managed to source parts from rock auto, but they won't arrive for several days, and they don't seem to come with new bolts. I would like to...

I just discovered the OBD 2 port... How to use it? [cable/software/hardware... what exactly?] Can i recover much useful data about car from it?
