Electronics can be much easier to detect for faults than mechanical equipment. Most sensors should have certain readings under normal conditions.
When you turn your key on, all of those indicator lights are telling you the testing electronics is working. If VDIM doesn't test out correctly after you start the vehicle, the light would remain on and perhaps during those conditions, other systems like ABS only would take over.
As I said, it's a lot easier when electronics are involved because many routines can be written to bypass, and redundant mechanical systems are connected together electronically.
