HELP! Power Steering CEL
 

I'm on the road pulling my KL behind my motorhome for the first time and need some help. I screwed up wiring my on vehicle charger so two days into a two month trip my battery was flat. Fixed that with a trickle charger and changing the pin location on my on vehicle charger, but now the EPS won't shut off and I'm getting a "Service Power Steering" message. I have the "death wobble" fix installed, but changing the switch to the run versus tow position hasn't changed anything ...

Any suggestions?
