GSA Electronic Suspension ESA

Does anyone know if the electronic side of the ESA units can be checked to find out if there is a problem.

I am assuming that there is a voltage output to the damping units and preload.

Also does the GS911 unit pick this up if there is an issue.

Only via dealer diagnostics but then this relies on coupling leads to the control units & a pin brake out box. There are no actual values available for the internals of the units.
