From this 730-01-02 xxxx xxx1 xxxx
To this 730-01-02 xxxx xxx0 xxxx
1=enabled 0=disabled
Felt the difference right away. Then a month later I got curious and turned it back to its original value but also did the Calibrate Longitudinal Sensor procedure as well so I am not sure if re-enabling the pull/drift compensation allowed it to relearn since just disconnecting battery doesnt change it or if the calibration procedure corrected it or it may have been both. From what others have posted just disabling it and re-enabling right after doesnt work. Need to drive with it off for couple days then try turning it back for it too relearn. Can also just leave it off as well if you wish.

Disabling it left the wheel centered while driving ans didnt have the drift/wandering issue. Drove like how it is supposed too. I didnt get an alignment afterwards as I had 2 done before hand and felt it wasnt worthwhile to do another.

The wheel itself was centered. It was when I was driving it would be off center as I was having to keep making corrections. After I did that the wheel was straight and didn't have to keep making corrections.

If that doesn't work (which I don't think it will) I will reset the abs sensor. I will try that a bit. If that doesn't work, I will try and disable the pull/drift compensation. My only concern is my truck has Lane keep assist. I hope that disabling the compensation doesn't make the truck go crazy because of the LKS. I don't mind losing the LKS (I don't use it and I think it is part of the issue and would rather not have it) but I don't want to have more problems because of it.

By the way, none of these electronic adjustments are going to change the physical steering wheel angle. You can only zero the EPS steering sensor when the front wheels are straight, but the steering wheel itself might be off. On my truck, it's a bit off since new, but not worth taking it to a dealer, so left it as is. Somehow, the PDC seems less annoying now, which is why I haven't felt the need to mess with it. But I'm curious to turn it off and then back on and see what changes. And maybe also try the Calibrate Longitudinal Sensor procedure, once I find out what exactly it does . Is it the same thing as the zero angle? Thx.

Its supposed to be similiar to that IVD initialization procedure that is in IDS. I don't know the specifics of what it actually does. The procedure itself is really simple. All it has you do is hold the wheel in the straight ahead position and you select calibrate on the pop up menu.
