 (b) Wait for 3 seconds and close the circuit breakers.

 (c) Wait for 60 seconds

 (d) Check the UPPER ECAM and the SD FLT/CTL page for the fault warnings.

 (e) If the ECAM warning message clears, set the MCDU to MENU MODE and access the FLP ON GROUND FAULTS page and make sure that the ground log is clear.

 (f) If the ECAM warning and the fault message stays displayed do the procedure at Para.4.C.

 C. Procedure
 (1) Swap the SFCC 1 (2) with SFCC 2 (1) (Ref. AMM TASK 27-51-34-000-001) (Ref. AMM TASK 27-51-34-400-001).
 (a) If the fault moves with the SFCC 1 (2) to the SFCC 2 (1) position, the fault is in the SFCC 1 (2).

 (2) Return the SFCC 1 (2) and 2 (1) in their initial locations and replace the unserviceable SFCC-1 (21CV) (SFCC-2 (22CV)) Refer to Para. 4.A.(1).

 (a) If the fault remains in the SFCC 1 (2) the fault is in the SFCC 1
 (2) interface/circuit or CFDIU

 (3) Do a check of the aircraft wiring between the CFDIU ARINC connector and the SFCC 1 (2) ARINC electrical connecter. (Ref. AWM 27-51-21) (Ref. AWM 27-51-22).

 (4) If there is no continuity repair the wiring/interface.

 (5) Do the Reset as in Para. 3.A.(2)(c).

 (a) Set the MCDU to MENU MODE and access the FLAP ON GROUND FAULTS page and make sure that the ground log is clear.

 (6) If the fault remains,the fault is with the circuit inteface to the CFDIU, refer to TSM page block 101 34- 12- 00.

 B. Procedure
 (1) At the circuit breakers.

 (a) Examine the C/B for integrity.

 (b) Do a check of the A/C HOT BUS 28VDC supply. (Ref. ASM 24-68/12) (Ref. ASM 24-68/13)

 (c) If the fault is found at steps 4.A.(1)(a) and/or (b), do the repair and do the test at step 3.A.(1).

 (2) If the fault continues.

 (a) Swap the SFCC 1 and SFCC 2. (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001).

 (b) If the fault moves with SFCC 1(2).
