All I have found so far is that "The damping action of spring struts is thus adapted at the front and rear via electrically actuated control valves." The documentation on earlier ESA versions talks about a stepper motor which I presume just does electrically what you would otherwise do with a screwdriver on the adjuster, but electrically actuated valves sounds a bit more advanced.
This article indicates that damping is controlled by a solenoid adjusted valve inside the shock, so it should have a reasonable range, though I doubt it can adjust compression and rebound separately.
