(a) Access the FLP ON GROUND FAULTS and do a check of the ground log.
(b) If the fault moves with SFCC 1 (2).
(c) Replace SFCC-1 (21CV) (SFCC-2 (22CV)) Ref. Para.4.A.(2)(a).
(3) Move the slats and flaps control lever from and to a valid position.
(a) Examine the ECAM EWD and the SD FLT/CTL page and check if the fault clears.
(b) If the fault message clears, access the FLP ON GROUND FAULTS page and make sure the ground log is clear.

A. SFCC system exitation power test.
(1) Do the SYSTEM TEST (BITE) on the SFCC 1 (2) (Ref. AMM TASK 27-51-00-740-002). The fault data" PPU excitation power short circuit" is displayed. Page block 301 table 7 gives the SFCC test menu selections details.
(2) Do the fault isolation.

4. Fault Isolation
_______________
A. Procedure
(1) Make sure that there is no SFCC to PPU external circuit/interface short circuit fault, before troubleshooting the SFCC 1 (2).
(a) Do a check of the A/C wiring/interface between SFCC 1 (2) and the PPUs'. (Ref. ASM 27-51/01) (Ref. ASM 27-51/08)
(2) If there is a wiring/interface fault, do the repair.
(a) Do the BITE test of the SFCC 1 (2).
(b) If the same fault message is shown and there are no circuit/interface faults.
(3) 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 FLP 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 the unserviceable SFCC-1 (21CV) (SFCC-2 (22CV)) Ref. Para.4.A.(1). 中國航空網 m.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320 Trouble Shooting Manual 排故手冊 飛行操縱 1(93)
