B. Test
(1) Read the:
(a) Paragraph titled Intermittant fault (Ref. TSM INTRO, 3.G(2)(b)2_).
(b) Technical Follow-Up (Ref. TFU 28.15.00.003).
(2) Do the Functional BITE Test (of the FLSS) (Ref. AMM TASK 28-46-00-740-001).
(a) Examine the FLSS STATUS page. Look for one (or more) of the messages that follow:
- L LO LEVEL SENSOR 16QJ1
- R LO LEVEL SENSOR 15QJ2
- FLSCU1 7QJ
- FLSCU2 9QJ.
(b) If a message(s) listed (in the step before):
- is not shown, do step (3)
- is shown, trouble shoot the LRU(s) before you do step (3). Refer to the Fault Symptoms List/28-CFDS for the related Task number.
(3) Do the Functional BITE Test of the Intercell Transfer Valves (Ref. AMM TASK 28-15-00-740-002).
NOTE : The COMMAND FLSS BITE option does not test the intercell
____
transfer valves (ICTVs).
NOTE : The ICTVs are motor driven and the electrical power for these
____ circuits is supplied from 801PP, 28VDC, ESS BUS/SHEDDABLE (Ref. ASM 28-15/01). The ICTVs will not operate on battery power.
(a) Examine the FLSS STATUS page. Look for the (left wing rear ICTV) message XFR VALVE 30QM/73QM/12QP.
