Calibration/basic setting is done by parking on flat level ground and going into module 55 and running basic settings, this will tell the vehicle what its base parameters are, if done succesfully the headlights will dive and then level and the fault will be gone but you cannot run basic settings when the levelling controller cant see the level sensors which is what your fault scan is reporting !
You need to check that level sensor wiring and connections and get them working first
