NOTE : The ICTVs are motor driven and the power for these circuits is
____ derived from the main power. The ICTVs are immobilized on battery power.
(1) If failures are detected examine the FLSS STATUS page for any of the messages that follow:
- L LO LEVEL SENSOR 15QJ1
- R LO LEVEL SENSOR 15QJ2
- L LO LEVEL SENSOR 16QJ1
- R LO LEVEL SENSOR 16QJ2
- FLSCU1 7QJ
- FLSCU2 9QJ.
(2) If none of the above messages are shown:
- go to step Para 4.
(3) If one or more of the messages identified in Para B.(1) are shown:
- trouble shoot the LRU(s) before you start more steps. Do the trouble shooting procedure related to the failure message.
4. Fault Isolation
_______________
A. Set the MCDU to SYSTEM REPORT/TEST (FUEL), then for:
- 06 FQIC Software Standard go to the FQIS STATUS page
- 07 FQIC Software Standard go to the FLSS STATUS page.
(1) If both the XFR Valve messages are shown:
- (Ref. TASK 28-15-00-810-803) for the Left Wing Forward Intercell XFR VALVE (27QM/70QM/9QP) message
- (Ref. TASK 28-15-00-810-804) for the Left Wing Rear Intercell XFR VALVE (28QM/71QM/11QP) message.

B. Do the FLSS BITE Test (Ref. AMM TASK 28-46-00-740-001).
NOTE : If the aircraft is already supplied with electrical power, reset
____ the FQIC. (Open, then after 5 seconds, close the two C/Bs 1QT and 2QT). The FLSS BITE test is carried out once a short time after power up. After a two minute delay to allow the FQIC to do the BITE test, continue.
NOTE : The intercell transfer valves (ICTVs) are not tested by the
____ COMMAND FLSS BITE option. (This option only available with 07 FQIC Software Standard).
