Damn, you found how to disable that stupid 'pull drift compensation'? Awesome 
. A lot of forum members will be very happy to see that. Ha ha. That's the feature that constantly pulls on the steering like when going over a crowned road, but it hasn't bothered me that much yet, fortunately. But glad to have the option to turn it off. As of the other features, only the first is kind of self-explanatory, but non-existent unless you have 4WD/4A activated, since it involves traction in the front wheels. The other 2 in the middle I have no idea. Hopefully somebody can shed some light on those.
Hey FordXLT, what did you 'fix'? I don't see any difference on WreedSVT's post vs your quote. Maybe he edited his post already. Just want to make sure those figures are correct. Are all of those enabled from the factory? Thx.

TSC is enabled on FWD applications. So it's on for the Explorer and Fusion etc etc.
Soft stops I think are also only on for the FWD applications but I can't think of why. So that you can put in a limiter as to how much turn it will produce, IE FWD application can't put the wheels at as much of a steering angle as RWD can tolerate.
And I think active return is active for the sports cars (mustangs with PP, explorer Pursuit, focus RS etc) But I could be wrong. The idea being their alignment specs don't have as much caster angle so it's to let the module gently return the to center.
The pull drift bit I think is ON for all. But again I can't think of why that is but I think it's a feature set for the stability assistance system

Oh I sure wish I saw the PDC disable code. I would have turned it off to see if it helped with the erratic steering on that POS 16 I had.
