The preceding figure shows a MAP display during a ROM/RAM query of a
system-busy DTC. The next switch operating system (SOS) audit notes the
system-busy state. The audit initiates system maintenance in order to return
the DTC to service.
During the period that the DTC returns to service, a ROM/RAM query
determines the state of the PM. During that period, a ROM/RAM query also
determines if the PM needs to be loaded again. The ROM/RAM query
requires less than 1 min to finish. The preceding figure shows a loss of
software load.

The preceding figure shows a MAP display of system maintenance that
determines if auto loading is necessary after the system detects a loss of load
during the return-to-service task. The DMS-core displays a system recovery
message for the DTC until the recovery process starts.
The message indicates that the system flagged the load arrangement for the
DTC to the SRC. While the message appears, the group manager groups
similar PMs, if necessary, and allocates DMS-core resources.
