R 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 center tank must contain 2000kg (4400lb) of fuel to fully
____
test the cadensicon.
(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).
