 Intercell XFR Valve 30QM/73QM/12QP (Right Rear) Fault - Stays Closed When The Fuel In The Inner-cell Is At Low Level
 WARNING : OBEY THE FUEL SAFETY PROCEDURES.
_______
 WARNING : WHEN YOU DO WORK ON THE FUEL SYSTEM WIRING, YOU MUST USE TEST
_______ EQUIPMENT THAT IS APPROVED (REFER TO INTERNATIONAL OR NATIONAL SPECIFICATIONS FOR INTRINSICALLY SAFE TEST EQUIPMENT, E.G. EN50-020, UL913 OR EQUIVALENT). TEST EQUIPMENT THAT IS NOT APPROVED CAN CAUSE FIRE OR AN EXPLOSION.
 1. Possible Causes
_______________
 - ACTUATOR-TRANSFER VALVE, R REAR SPAR (12QP)

 - aircraft wiring

 - RELAY-R WING TK LOW LEVEL CHANNEL B (6QP)

 - RELAY-L WING TK LOW LEVEL CHANNEL A (5QP)

 - RELAY-L OR R REAR XFR VALVE OPEN LATCH (13QP)

 B. Test
 (1) 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 (2)

 - is shown, trouble shoot the LRU(s) before you do step (2). Refer to the Fault Symptoms List/28-CFDS for the related Task number.

 (2) 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 (right wing rear ICTV) message XFR VALVE 30QM/73QM/12QP.

 (b) If the message:

 - is shown, do Para. 4.A.

 - is not shown, no work steps are necessary.
