Hi guys. I have a 2013 fiat 500 red power steering dash permanently on and only code in brain was u1702??? The car has a cheap nasty lion battery although seems to have no starting issues and drives fine just no power steering at all. Checked 70amp fuse. Looking at stripping out motor-ecu sending off to bba reman but gonna try a decent brand new battery before just incase as a top tech told me the battery has to be too top as the current draw from eps or won’t work? Any help ideas appreciated thanks
