A. Select MCDU MENU mode, set the CFDS then A/C CURRENT STATUS or AVIONICS STATUS.
(1) Do a check of the STATUS report and look for a SFCC-1 (2) fault on the SDAC, CFDIU, ELAC, FAC and SEC.
(2) If these systems identify an SFCC-1 (2) fault, do the fault isolation.
4. Fault Isolation(1) Do a check of the STATUS report and look for a SFCC-1 (2) fault on the SDAC, CFDIU, ELAC, FAC and SEC.
(2) If these systems identify an SFCC-1 (2) fault, do the fault isolation.
NOTE: If the SFCC identified defective is failed or under MMEL (SLAT SYS x FAULT), this procedure is not applicable. This fault is a consequence of the failure or MMEL condition.

A. Special Procedure (refer to the NOTE)
AMM 27-51-34-000-001 and AMM 27-51-34-400-001.
(a) Do the procedure at Para. 3.A.(1).
(b) If the fault moves to the other SFCC position:
1 Install the serviceable SFCC in its initial position.
2 Replace the defective SLAT/FLAP CONTR.COMP. [21CV] or SLAT/FLAP CONTR.COMP. [22CV] .
3 Do the procedure at Para. 3.A.(1).
(c) If the fault does not move to the other SFCC:
(a) Do a check of the aircraft wiring between:
(c) Do the procedure at Para. 3.A.(1).
(d) Get access to the FLAP/SLAT ON GROUND FAULTS page and make sure that there are no faults.
NOTE: This fault isolation procedure is for a fault (loss of data) which is not identified by the SFCC-1(2). The source of this fault is the EFCS.
(1) Interchange SFCC-1 with SFCC-2 AMM 27-51-34-000-001 and AMM 27-51-34-400-001.
(a) Do the procedure at Para. 3.A.(1).
(b) If the fault moves to the other SFCC position:
1 Install the serviceable SFCC in its initial position.
2 Replace the defective SLAT/FLAP CONTR.COMP. [21CV] or SLAT/FLAP CONTR.COMP. [22CV] .
3 Do the procedure at Para. 3.A.(1).
(c) If the fault does not move to the other SFCC:
- Install the SFCCs in their initial positions.
(a) Do a check of the aircraft wiring between:
- The SFCC-1 (2) FLAP ARINC connector tray and the BUS connector to 1853VT (SFFC 1 AWM 275123) (SFFC 2 AWM 275124).
- The SFFC-1 (2) SLAT ARINC connector tray and the BUS connector to the first terminal blocks (SFFC 1 1862VT and 1833VT AWM 278123) (SFFC 2 1862VT and 1842VT AWM 278124).
(c) Do the procedure at Para. 3.A.(1).
(d) Get access to the FLAP/SLAT ON GROUND FAULTS page and make sure that there are no faults.
