All safety tests are performed in AUTO, L1 or L2. Auto only cycles the relays to try to automatically determine the service level, this is not a safety test. In Europe with single phase 230v the correct setting is L2. With the setting saved there is no reason to cycle the relay to try to determine the service level, it is actually safer as there is never power on the EV plug even for a short time while determining service level. Regardless of the service level stuck relay test is performed any time the relay is open and the ground test is performed any time the relay is closed.
