Fault codes U0421-68 & C1B00-64 after front bushing repa

On my 2011 RRS I had to replace the lower rubber bushings in the front lower suspension arms. On one 1 side I really problems getting the ball-joint loose and maybe over extended the height sensor on that side.

I now have 2 dtc's which are ABS and Height related. Cleared those but came back.

U0421-68
C1B00-64

It is possible to determine which sensors are involved (I worked on both front sides) ? Checked cables and mechanism from a visual point of view. No issues there. Cleared the ABS rotor and sensor also.

Currently I have warning (DSC and HDC are not working) appearing on my dashboard, which can be cleared with OK.

If HDC and DSC aren't working, that points to a wheel speed sensor or related wiring problem 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Have you had a 4 wheel alignment carried out? I understand that if you have work done on the wishbone, it needs an alignment check/adjustment and if not done can throw up faults. You really need someone who knows these cars, preferably with a Hunter rig.

I did read the alignment statement after posting my question. It makes sense although I marked the positions of the alignment bolts and used these marks for alignment when installing the wishbones with replaced bushings.

Wiring seems fine and I checked if I damaged wiring (but I didn't). Warnings indeed only pop up above 50 km/h. After shutting down the car, these disappear.

Wheels aligned at a dealership and it seems to resolve the issue. (Only 40 miles done so far)

Since the repair the warning messages did occure less and less. Where initially these would appear with 1-2 miles, after 2 weeks I could do between 10-15 miles before these would pop-up. Hopefully this information helps others.
