What should a field engineer do about C0900003?

An abort issued during pre-processing went unanswered. Check the data processing unit (the MHR boards in the REC BOX) for a communication fault: review the event log around the aborted scan, confirm the MHR boards are running, and retry the operation.. Isolate the RTM — ELCTL (pre-process / recon control) subsystem and follow the status-code troubleshooting in the service manual. FSELIB documents the full diagnosis and remedy for the Aquilion RX / V4-62R004 / V3.20R003 / Aquilion ONE / V4.2 / Aquilion S16 / Asteion Super4 / Aquilion 16.
