(b) If the ARINC INPUT STATUS page shows LGCIU LABEL *** NO DATA, do the fault isolation.
(2) If the ARINC INPUT STATUS page shows LGCIU 1 (2) OK.
(a) Do the SFCC 1 (2) Reset and Initialization.

4. Fault Isolation
_______________
A. 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
(d) Check the UPPER ECAM and the SD FLT/CTL page for the fault warnings.
(e) If the ECAM warning clears, access the FLP ON GROUND FAULTS page and make sure that the ground log is clear.
(f) If the checks at Para.4.A.(1)(e) are satisfactory there is no further maintenance action.
B. Procedure,
(1) Swap the LGCIU 1 with LGCIU 2 (Ref. AMM TASK 32-31-71-000-001) (Ref. AMM TASK 32-31-71-400-001).
(2) Access the submenu page "SYSTEM DATA FLAP" and press the line key "2L".
(a) The page shown is the "ARINC 429 INPUT STATUS" and is refreshed every 5 seconds.
(b) If the ARINC INPUT STATUS page shows "LGCIU 1 (2) OK",then the initial LGCIU 1 (2) is at fault.
(3) Install the LGCIU 1 and 2 in their initial locations and replace the unserviceable LGCIU-1 (5GA1) LGCIU-2 (5GA2) . Refer to Para. 4.B.(1).

(4) Go to the submenu page "SYSTEM DATA FLAP" and access the "ARINC 429 INPUT STATUS"page.
(a) If the fault remains in the SFCC 1 (2) the fault is in the SFCC 1
(2) interface/circuit.
(5) 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).
(6) Go to the submenu page "SYSTEM DATA FLAP" and access the "ARINC 429 INPUT STATUS"page, SFCC 1 and then SFCC 2.
(a) If the fault moves with the SFCC 1 (2) to the SFCC 2 (1) position, the fault is in the SFCC 1 (2) input interface.
(7) Instal the SFCC 1 and 2 in their initial locations and replace the unserviceable SFCC-1 (21CV) SFCC-2 (22CV) Refer to Para. 4.A.(3).
(a) Do Para. 4.A.(6). If the fault remains in the SFCC 1 (2) interface/circuit.
(8) Do a check of the aircraft wiring between the LGCIU 1 ARINC connector and the SFCC 1 (2) ARINC electrical connecter. (Ref. AWM 32-61-05) (Ref. AWM 32-61-06).
(9) If there is a fault repair the wiring/interface.
(10) Do the BITE test as in Para. 3.A.(2) and Para. 3.A.(4).
(a) Set the MCDU to MENU MODE and access the FLAP ON GROUND FAULTS page and make sure that the ground log is clear.
5. Close-up
________
A. Put the aircraft back to its initial configuration.
