My 2008 GS SE5 started to act up yesterday. It seems like power steering turns off at higher speeds. Hard to turn at over 10 mph, seems fine at lower speeds( easy to turn the handlebars). Sometimes while making a left/right turn seems like I am about to lose control. OK changing lanes. No mods, 15,000 miles, checked the fuses all seem OK, tried to pull the codes- "no active codes". New battery 3 months ago. Any ideas?
