(b)
Word 2 This word is assigned to the hardware faults and is only filled when an hardware fault occured. It includes a field for the unit intrnal hardware monitoring, a field for unit self test and a field for the reset or interupt.
(c)
Word 3 This word is assigned to the software faults and is only filled when a software fault occured. It includes three different fields similarly to the hardware word.
(d)
Word 4 This word is assigned to the operational data at the time of the recorded fault such as the status of the switching selectors, the DUs status.
(e)
Word 5 This word includes the index of the fault as seen by the supplier of the item.
(f)
Word 6 to 15 These words include the complementary data transmitted by the source at the time the fault occured.

(g) Internal failures
The failure codes consist of 4 digits.
-The first digit indicates the item of equipment (Display Unit or DMC board or other) affected by the failure.

-The next three digits give the precise error code.
(h) External failures
The failure codes also consist of 4 digits.
-
the first digit is always E (like external)
-
the next three digits indicate the origin of the failure, i.e. the source which is seen faulty. The table below gives the correspondence between these numbers and the various DMC sources:

EIS LRU identification
(Ref. Fig. 058)

Dump of the BITE memory (Ref. Fig. 059) The DUMP BITE MEMORY function displays a menu which presents the following failure items:
-INTERNAL FAULT IN FLIGHT
-EXTERNAL FAULT IN FLIGHT
-FAULT ON GND and a FAILURE COUNTER RESET item to reset the failure counters. For the INTERNAL FAULT IN FLT and EXTERNAL FAULT IN FLT menus, the first two lines give a foreword, and the following lines correspond to numbered events with detailed information on the successive failures (Ref. Fig. 060) For the FAULT ON GND menu, there is no foreword (not necessary). Note that the EIS internal faults which could occur on the ground are recorded in the zone 3 of the BITE memory, and are not transmitted automatically in plain english language to the CFDIU. The only access to this zone is by memory dump (Ref. Fig. 061) A failure counter is associated with each failure. This counter is incremented at each failure occurrence. it is reset by means of the line key adjacent to the FAILURE COUNTER RESET indication.
