That being said, I am at work now. I did see your thread and planned on digging a bit but it looks like @ Tcoat beat me to delivering the bitter reality. Your dealer probably just fired up techstream against it and pulled those specific indicators. A compound failure is rare. If I was to believe the dealer's diagnosis, personally, I would dig further into the servo system looking for an intermittent open. Closed-loop servo systems can be notoriously difficult to troubleshoot but one might get lucky finding an intermittent loose connector.
Your choice is to either have the dealer do the work, or snag a copy of techstream and try swapping/calibrating a known good drive unit. This is one of those "if you have to ask..." situations. 
edit: I don't think it's the motor. That's usually a hard failure. |
@
Tcoat @
Ultramaroon so you both think the EPS motor replacement and return to the shop will ultimately not be the solution, correct?
Both of your understandings of these circuits are far beyond mine, so if this is self-evident then I'm embarrassed, but would the steering column replacement that they suggested negate all of the 30+ failure scenarios that you saw it could potential be, and be far enough into 'starting from scratch ' that the replacement of the entire column will likely resolve my issue completely? Or is it still somewhat likely to error after the steering column replacement?
