 3. Fault Confirmation
__________________
 A. Test
 (1) Do the BITE test of the FLSS (Ref. AMM TASK 28-46-00-740-001).

 (2) Examine the FLSS STATUS page on the MCDU.

 (3) If the page shows messages for one or more of the other sensors and/or the FLSCU-1(2), do (Ref. TASK 28-46-00-810-818).

 (4) If the message 284617 L(R) OUT TEMP SENSOR 30QJ1(2):

 - is shown, do Para. 4.A.

 - is not shown, no work steps are necessary.

 NOTE : You can get more data from the:
____
 - Aircraft Maintenance Manual (AMM) Chap. 28-46-00, the Fuel Level Sensing System, Description and Operation (D and O)

 - Trouble Shooting Manual (TSM) - Task Supporting Data (Ref.

 P. Block 301)

 - Aircraft Schematic Manual (ASM) (Ref. ASM 28-46/04). You can get more Trouble-shooting data from the CFDS(FUEL):

 - Input Parameters Page 3 (Ref. P. Block 301), used with the Fuel Temperature Level Sensors Operating (Changeover) Values (Ref. P. Block 301)

 - FLSCU Trouble-shooting Data (Ref. P. Block 301).

 NOTE : OPTIONAL TESTING:
____ Where a PSD A320-2 Fuel Level Sensing Test Set is available measurements can be taken before a decision is made to go into or close up a fuel tank. The Test Set enables the tank mounted components and tank wiring to be tested from the tank wall connectors.
