Good morning,
I just finished replacing the dampers on my 2010 Rapide, and I am now getting a "ADS off" error message on the dash, and the suspensions go into the "harsh" mode...
I ran my scanner and it's giving me 2 codes:
- C110E = Left rear damper valve fault
- C110F = Right rear damper valve fault
I can erase them, but they will show up the next time I start the car.
I am not getting error messages for the front dampers, so I assume it's not the module.
Any help appreciated, thank you!

 

Bad new parts? Plug in the old ones and clear/cycle the key. I'd venture to say continuity to the new rears is open circuit.
