Interrogation of the (SIMMONDS/GOODRICH) FQIS Trouble Shooting Data

TASK 28-42-00-740-009-A
Interrogation of the (SIMMONDS/GOODRICH) FQIS Trouble Shooting Data

WARNING: OBEY THE FUEL SAFETY PROCEDURES.
1. Reason for the Job
For the pre FQIS aircraft configuration, this task shows you how to access the "FQIS TROUBLESHOOTING DATA" pages on the Multipurpose Control & Display Unit (MCDU). The troubleshooting data is available when a Line Replaceable Unit (LRU) is given as a fault message. The cross reference tables are supplied to let you read (decode) the related troubleshooting data (that is shown in a hexadecimal format).

B. Definition (explanation) of the Troubleshooting Data

The steps that follow are to show you to how to use the six (hexadecimal) words given by a channel (or each channel). Each channel is decoded by the same procedure.

To aid the explanation an example is taken from the MCDU display (FUEL - FQIS STATUS, with a fault shown) as follows:

Example (from the MCDU Display shown above)

-------------------------------------------------------------------------------
! Troubleshooting data message ! 065C 7F81 FDFF FFFF 8FCF !
! ! 0002 !
-------------------------------------------------------------------------------

   (1) Failure Index and Event Number

The four characters (hex numbers) of the first (left side) word make up the failure index and event word.
     (a) The Failure Index is made from the first three characters of the first word. It is used in its original (hex) form as follows:
       1 Make a record of the three characters.
       2 Go to Para. 4.C. - FAILURE INDEX (H).
       3 Look down the list to find your recorded three characters in the table.
       4 When you find the three characters make record of the related data description from the table.
NOTE: From the Troubleshooting data message example this is 065.
From Para. 4.C - FAILURE INDEX,
065 (H) = FQIC master pin prog status.
     (b) The Event Number is the last character of the first word. It is used in its original (hex) form as follows:
       1 Make a record of the character.
       2 Go to Para. 4.D. - EVENTS (H).
       3 Look down the list to find your recorded character in the table.
       4 When you find the character make a record of the related events description from the table.
       5 Go to the related Para. 4. given in the end column for snapshot words descriptions.
NOTE: From the Troubleshooting data message example this is C.
From Para. 4.D - EVENTS,
C = FQIC MONITORING 1 = Para. 4.R. for the related snapshot descriptions.
   (2) Snapshot Words

The five words that follow (in the example) are the snapshot words and have to be changed from their original hexadecimal code into a binary coded hexadecimal format.
     (a) The change (conversion) of words from hexadecimal to binary and is best shown (explained) with the troubleshooting data message example:
-------------------------------------------------------------------------------

       1 Use the Table 001 as a reference to change each four bit hex word into binary coded hex as follows:

-------------------------------------------------------------------------------
! 1st snapshot word ! 2nd snapshot word ! 3rd snapshot word !
! 7F81 (H) ! FDFF (H) ! FFFF (H) !
! 15 bit 0 ! 15 bit 0 ! 15 bit 0 !
! 0111 1111 1000 1(H) ! 1111 1101 1111 1111 ! 1111 1111 1111 1111 !
!-----------------------!-----------------------!-----------------------------!
! 4th snapshot word ! 5th snapshot word ! !
! 8FCF H ! 0002 H ! !
! 15 bit 0 ! 15 bit 0 ! !
! 1000 1111 1100 1111 ! 0000 0000 0000 0010 ! !
-------------------------------------------------------------------------------

       2 Record your result of the change from hex to binary 1s and 0s on the related snapshot words. Start with bit 0 at the bottom of the snapshot table and finish with bit 15 at the top. Put your 1s and 0s in front of the applicable True or False entries in the column identified VALUE.
NOTE: All the Snapshot Word 1 tables start at bit 4. This is because the first hex character/digit stays in that format. From it you can find which trigger description (from those listed) that gave the original fault message.
     (b) Trigger Number
       1 Make a record of the original hex character and stay in Para. 4.R. - FQIC MONITORING 1.
       2 Go to:
  • snapshot word 1 for trigger numbers (H) 1 thru C
  • snapshot word 2 for trigger numbers (H) D thru 0.
       3 In the second column under TRIG, find your trigger hexadecimal character/number.
       4 Make a record of the trigger description from the table.
NOTE: From the Troubleshooting data message example this is 1.
From Para. 4.R - FQIC MONITORING 1, snapshot word 1
TRIG 1 (on row/line bit 04) = CPU healthy boolean before confirmation - not healthy
