(13) If the FOB:
(a) Shows a fuel total that is not degraded, no more maintenance steps are necessary.
(b) Shows degraded, remove (erase/delete) from the (your) record of fault messages, those fault messages (fuel probe LRUs) that are not installed in the degraded tank/cell given in step (2)(a).
1 For the rectification of the FOB degraded fault:
_
a Refer to the list of CFDS FAULT MESSAGES (LRUs) in P. Block
_ 101, 28-CFDS, for the applicable FAULT ISOLATION PROCEDUREs related to the final record of FAULT MESSAGES in step (13)(b).
b Do the applicable/related TSM tasks.
_
NOTE : This procedure identifies which TSM procedures are
____ applicable when the FOB shows degraded. The possible causes are listed in the applicable procedures.
c Do the check in Para. 3.B(2).

A. Procedure
(1) On the ECAM CONTROL PANEL, push (in) the FUEL P/BSW.
(2) Examine the FUEL system page to see at which location(s) the tanks show degraded.
(a) Make a record of which tank is degraded.
(3) If available, read the POST FLIGHT REPORT (PFR) to see if any FQIS, FAULT MESSAGES are shown.
(a) Make a record of all the FQIS, FAULT MESSAGES shown.
(4) Do the procedure to get access to the SYSTEM REPORT/TEST menu page (Ref. AMM TASK 31-32-00-860-001).
(5) When the SYSTEM REPORT/TEST menu page comes into view, push the line key adjacent to FUEL.
(6) When the FUEL menu page comes into view, push the line key adjacent to FQIS STATUS.
(7) Examine the FQIS STATUS page and make a record of all the FAULT MESSAGES shown.
NOTE : If necessary, use the MCDU PRINT option to get the record.
____
(8) Reset the FQIC as follows:
(a) Open the C/Bs 1QT and 2QT.
(b) Wait 10 seconds.
(c) Close the C/Bs 1QT and 2QT. NOTE : For the FQIC to do a (new) power up BITE test, a power
____ supply interrupt (interval) of more than 10 seconds is necessary. This gives the current status of the FQIS components.
NOTE : The FUEL page FQIs will show XXs in amber color, for 35
____ seconds, during the FQIC power up BITE test. A FQIS sensor fault must be sensed by the FQIC for 60 seconds before the applicable LRU identification is transmitted to the CFDS as unserviceable. The fault message is shown on the MCDU when set to SYSTEM REPORT/TEST (FUEL) and the FQIS STATUS page.

(9) When the BITE test is complete (XX shown on the FQIs for 35 seconds and the display has no dashes for 60 seconds), examine the FQIS STATUS page (again) for FAULT MESSAGES shown.
(10) If, after the FQIC reset, any fault messages recorded in steps (3)(a) and (7) are not now shown, remove (erase/delete) them from the (your) record.
NOTE : Maintenance steps are not necessary for those fault messages
____
because they are considered spurious.
(11) Do a check of the upper ECAM, ENGINE/WARNING DISPLAY to see if the FOB is (has stayed) degraded.
(12) If the FOB:
(a) Shows a fuel total that is not degraded, no more maintenance steps are necessary.
(b) Shows degraded, remove (erase/delete) from the (your) record of fault messages, those fault messages (fuel probe LRUs) that are not installed in the degraded tank given in step (2)(a).
1 For the rectification of the FOB degraded fault:
_ a Refer to the list of CFDS FAULT MESSAGES (LRUs) in P. Block
_ 101, 28-CFDS, for the applicable FAULT ISOLATION PROCEDUREs related to the final record of FAULT MESSAGES in step (12)(b).
b Do the applicable/related TSM tasks.
_ NOTE : This procedure identifies which TSM procedures are
____ applicable when the FOB shows degraded. The possible causes are listed in the applicable procedures.
c Do the check in Para. 3.B(2).
