Different status and diagnostics messages can be allocated to individual diagnostics events as
per the following tables. The frame in which an allocation is possible is defined by the group in
the selection column. The following principle is used: in case of three-stage diagnostics events
of the MAINTENANCE group, the effect of the higher lever events can be downgraded, but that
of the lower level events cannot be upgraded.
