__________________
 A. Test
 (1) At the MCDU, access the SYSTEM REPORT / TEST page and select F/CTL> (Ref. AMM TASK 31-32-00-860-006).

 (2) Select <SFCCX (where X is the No. of the applicable SFCC).

 (3) Select <SFCC/TEST, to do the SFCC BITE test:
 - if the fault message SLT1 (2) PCU VALVEBLOCK 25CV (26CV) VALVE SENSOR 27-84-53 is shown, do the Fault Isolation Procedure given in Para. 4.
 NOTE : This message is not a CFDS Normal Mode message and is only
____
 shown in SFCC reports.

 4. Fault Isolation
_______________
 A. Procedure
 (1) Interchange the SFCC1 and SFCC2 (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001).

 (2) Do the test given in Para. 3.A:

 (a) If the fault goes, replace the initial SFCC-1 (21CV) or SFCC-2 (22CV), (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001).

 (b) If the fault continues, replace the applicable VALVE BLOCK SLAT 1 (25CV) or VALVE BLOCK SLAT 2 (26CV), (Ref. AMM TASK 27-84-53-000-001) and (Ref. AMM TASK 27-84-53-400-001).

 NOTE : The valve sensor is not a Line Replaceable Unit (LRU) and
____ it is necessary to replace the valve block.
 (3) If the fault continues:
 (a) Do a check of the aircraft wiring and repair as necessary (Ref. ASM 27-81/02) or (Ref. ASM 27-81/03).

 (b) Do the test given in Para. 3.A.
