If fault data is not available from both EEC channels, you see a message that tells you which EEC channel the MCDU cannot use. You select CONTINUE to see the data for the channel the MCDU can use.
The dispatch level shows on line 3 of the FAULT HISTORY screen.
Line 5 gives the maintenance message number. You use this number to find the correct fault isolation procedures to correct the fault.
Lines 6, 7, and 8 give a short description of the fault.
Lines 9 through 11 shows the last 10 flight legs and which leg or legs has the fault. The X under the flight leg number shows the fault on this page occurred during that leg. Flight leg 0 is the most recent ground run. The EEC stores faults from this ground run in flight leg 1 when the airplane goes in-flight.
If there are no faults for the last 10 flight legs and the last ground run, the MCDU shows the NO FAULT HISTORY STORED message.
