Diagnostics!!
HDC is controlled via the ABS ECU, the Air Suspension and ABS all talk on the CANbus and rely on information from eachother so a failure in one system will shutdown the others!
Diagnostics first, As with all the lamps off on the height selector this indicates a hard fault with the Air Suspension System....I'd guess this is were the error sits.
As a fault with the ABS usualy makes the EAS go into soft fault only.
