 B. Test

 (1) To keep the number of computer replacements (with no fault found) to a minimum, do the power on BITE test of the FQIS as follows:
 NOTE : The inner cell fuel temperature on the FUEL System Display
____ page will show the air temperature when this probe is dry.
 (a) If the FQIS is not energized:
 1 Close the C/Bs 1QT and 2QT.

_ 2 Energize the Aircraft Electrical Circuits from the External
_ Power (Ref. AMM TASK 24-41-00-861-002).
 (b) If the FQIS is energized, reset the FQIC as follows: 1 Open the C/Bs 1QT and 2QT.
_
 2 Wait 5 seconds.

_
 3 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 5 seconds is necessary. This gives the current status of the FQIS components.
 (2) Do the EIS Start Procedure (ECAM only) (Ref. AMM TASK 31-60-00-860-001).

 (3) On the ECAM control panel, push (in) the FUEL P/BSW.

 (4) Make sure that the FUEL page shows on the ECAM lower display unit.

 (5) Wait 60 seconds.

 (6) Continue as follows: 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.
 (a) Do the procedure to get access to the SYSTEM REPORT/TEST menu page (Ref. AMM TASK 31-32-00-860-001).

 (b) When the SYSTEM REPORT/TEST menu page comes into view, push the line key adjacent to FUEL.

 (c) When the FUEL menu page 1 comes into view, push the NEXT PAGE key on the MCDU keyboard to see the FUEL menu page 2.
 NOTE : If a menu has more than one page (shown by the more to____ come symbol > on the top line, right side of the MCDU display) each operation of the NEXT PAGE key on the MCDU keyboard will cause the next page to be shown. When the last page of any menu is shown, operation of the NEXT PAGE key will cause the first page to be shown.
 (d) When the FUEL menu page 2 comes into view, push the line key adjacent to FQIS STATUS.
 (7) Examine the FQIS STATUS Page.
 (8) If the message L(R) QTY PROBE 22QT1(2):
 (a) Is not shown, maintenance steps are not necessary.
 (b) Is shown, go to Para. 4.A.
