B. Test
(1) Do the Power-on BITE test of the FQI system as follows:
(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-on BITE test, a power
____ supply interrupt (interval) of more than 5 seconds is necessary. This gives the status of the FQIS/FLSS components.
(2) Do the EIS Start Procedure (ECAM only) (Ref. AMM TASK 31-60-00-860-001).
(3) Make sure that the ADIRS is set to OFF. If necessary, do the ADIRS stop procedure (Ref. AMM TASK 34-10-00-860-005).
NOTE : This step is important if this procedure is being used to
____ trouble shoot a FQI display (ECAM and FQIS) fluctuation

(4) On the ECAM control panel, push (in) the FUEL P/BSW.
(5) Make sure that the FUEL page shows on the ECAM lower display unit.
(6) Wait 60 seconds.
