This feature was used on the high end LH models like the fully loaded Concorde, the LHS or later on the 300's. It was to give you a stiffer wheel from the power assist during high speed operation. Not only did I see very few in this model and year if the higher end computer was used this code would show up even if the car had none as a disconnect or open fault code. Diagnostics were run out of the body control module and were only reliable with Chrysler's DRBIII. To replace it both hoses must be disconnected at the steering rack, no easy job even on a new car, a 3.5L was especially tight to handle any tools in that area, plus the lines may need to be replaced if they are rusted badly. If you feel the need to repair it because of any steering problems, then do it by all means, you'll need to remove just the connectors of the two lines and use a crowsfoot wrench on the solenoid itself. By the way it uses fuse 9 and 14 I believe in the interior fuse block to operate and it is placed in an area prone to dirt and moisture, so it could be something damaged and shorted. I would say it's up to how it drives and how you feel about the way it is handling at high speeds since it cuts fluid at high speeds.
