Using the iidtool I deflated the system, changed the struts and then re-inflated with the re-enable EAS function. I'm not sure I completed it correctly. There was no notification that the re-enable was completed. Now I'm getting the listed error messages on the display. System seems to be holding air and height. Front R and L are off by about 1/2 inch. Any suggestions?

With HDC inactive I suspect an ABS sensor fault as that will also trigger a suspension fault.

Have you done the steering fully left then fully right? It could be something as simple as that... ______________________________

Yup - I would agree with that as well. Simple turning of the steering from lock to lock may address it. No IID tool or diagnostic kit will clear an error where the car is expecting the steering angle calibration to be completed. V8 or else ...

I'll try it today but why would it be necessary? Battery was not disconnected. Track rods weren't disconnected. ABS sensors weren't disconnected.

maybe it just knows that the system has been worked on.... they are fickle things.

Have you driven it?

Normal ABS / HDC system checks will not fully clear until you start driving and the car can tell that all ABS sensors are registering their readings properly. Did you disconnect / move any of them whilst changing the strut ? V8 or else ...

No disconnect of ABS but you need to remove the lines from the strut holder. Yesterday when the wife had the RR is when the warnings came on. I had only put about 15 miles on it before this and hadn't gone over 35 MPH. I cleared the codes when she got back. This morning had to go about 30 miles on highway. I did the left right steering wheel turn before heading out. No warnings yet. It wouldn't drop to highway height until I held 70 MPH for about 1 min. So I'm guessing I haven't actually damaged sensor in the refit.
