B. SFCC Reset and Initialization.
(1) At the circuit breakers.
(a) Open the circuit breakers.
(b) Wait for 3 seconds and close the circuit breakers.
(c) Wait for 60 seconds
(2) Do the operational test of the flaps system (Ref. AMM TASK 27-84-00-710-001)
(a) Check the UPPER ECAM and the SD FLT/CTL page for the fault warnings.
(b) If the ECAM warning clears. Access the SLT ON GROUND FAULTS page and make sure that the ground log is clear.
(c) If the ECAM warning and the SLT ON GROUND FAULTS message stays R displayed, do the fault isolation.
4. Fault Isolation
_______________
A. Procedure.
(1) Refer to step A.(2), and swap the electrical connectors 51CV-A and 51CV-B.
(a) If the fault moves to the other SFCC go to step 4.A.(2).
(b) If the fault remains in the same circuit do step 4.A.(4).
(2) Replace the CSU (51CV) (Ref. AMM TASK 27-51-17-000-001) (Ref. AMM TASK 27-51-17-400-001).
(3) Do the operational test of the slats system (Ref. AMM TASK 27-84-00-710-001).

(4) Swap the SFCC 1 and SFCC 2, (Ref. AMM TASK 27-51-34-000-001) for (Ref. AMM TASK 27-51-34-400-001) do Para.2,3 and 4 only.
(a) Access the SLT ON GROUND FAULTS and do a check of the ground log.
(b) If the fault moves with SFCC 1(2).
(c) Return the SFCC 1 (2) to their initial locations.
(d) Replace SFCC-1 (21CV) (SFCC-2 (22CV)) SFCC 1(2),
(5) Do the operational test of the slats system, reference step 4.A.(3).
(6) If the fault remains with same circuit, do step 4.A.(7).
