With the dsc you may need to turn steering wheel lock to lock, or just clear the code with inpa.

Happend on mine back in the day when i was messing around with ride height in the early days..

Right now mine is slammed 100% aired out in the front, and rears only have some air to make it level cause i turned off the whole air system, my front right popped so waiting on the new one.

but no dsc error.
