 3. Fault Confirmation
__________________

 A. Test
 (1) Do a BITE test on the SFCC 1 (2) (Ref. AMM TASK 27-81-00-740-002).
 (a) If the message SLT FPPU 28CV OR WIRING TO SFCC is shown, do the fault isolation.
 4. Fault Isolation
_______________
 A. Procedure
 (1) Interchange the two SFCCs (Ref. AMM TASK 27-51-34-000-001) (Ref. AMM TASK 27-51-34-400-001).

 (2) Do the test in Para. 3 A.

 (3) If the fault moves with the SFCC:

 (a) Replace the applicable SFCC-1 (21CV) or SFCC-2 (22CV).

 (4) If the fault does not move with the SFCC:

 (a) replace the FPPU-SLAT (28CV), (Ref. AMM TASK 27-81-19-000-001) R and (Ref. AMM TASK 27-81-19-400-001).
 (5) If the fault continues:
 (a) Use an ARINC Connector Breakout Box and do a check of the aircraft wiring, (Ref. ASM 27-81/06) and (Ref. ASM 27-81/07).

 (b) Do the repair.

 (c) Do the test in Para. 3. A.

 5. Close-up
________
 A. Remove the ground support and maintenance equipment, the special and standard tools and all other items.
 B. Put the aircraft back to its initial configuration.

 A. Test.
 (1) Do a BITE test with the applicable SFCC (Ref. AMM TASK 27-81-00-740-002).

 (2) If a message that includes the APPU 31CV (32CV) or the SFCC is shown on the MCDU, do the fault isolation procedure.
