CB RESETS

Power-up checks and their circuit-breaker resets

Nothing matches that symptom.
Type the message the aircraft shows, the computer or a panel — for example FCU FAULTS, AEVC or 49VU — or open a chapter below. Every breaker is a button into FIND CB, which shows where it sits on the panel.

REFERENCE ONLY — not authorized for maintenance, repair or return-to-service. A symptom here is what has been seen alongside a fault, which is correlation and not cause. The troubleshooting data decides what to do about a fault message, in the order it decides it, and a component changed because a pattern looked familiar is a component changed for nothing.
