- if there is a ground on pin Z and 28VDC on pin X, do step (3)

 - if there is no ground on pin Z, do step (4)

 - if there is no 28VDC on pin X, do step (6)

 (3) Replace the applicable flap fault relay:

 - for a FLAP SYS 1 FAULT message, replace RELAY-FLAP 1 FAULT (91CV)

 - for a FLAP SYS 2 FAULT message, replace RELAY-FLAP 2 FAULT (93CV).

 (a) Do a check of the upper ECAM DU for the ECAM warning FLAP SYS 1
 (2) FAULT:
 - if the message shows, do step (4)

 - if the message does not show, no more maintenance work is necessary.

 (4) Interchange SFCC1 with SFCC 2, (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001).

 (a) Do a check of the upper ECAM DU for the ECAM Warning FLAP SYS 1(2) FAULT:
 - if the fault moves to the opposite system, do step (5)

 - if the fault stays in the intial system, do step (6).

 (5) Replace the SFCC-1 (21CV) or SFCC-2 (22CV) identified in the ECAM warning message shown in step (4)(a), (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001):

 (a) Do a check of the upper ECAM DU for the ECAM warning FLAP SYS 1
 (2) FAULT:
 - if the message shows, do step (6)

 - if the message does not show, no more maintenance is necessary.

 (6) Do a check and repair as necessary the aircraft wiring between the applicable C/B and connector AA pin 3J of the SFCC mounting tray:

 - for relay 91CV, do the check from C/B 6CV and SFCC 1 (Ref. ASM 27-51/02)

 - for relay 93CV, do the check from C/B 8CV and SFCC 2 (Ref. ASM 27-51/03).

 (a) Do the Operational Test of the Flap System (Ref. AMM TASK 27-54-00-710-001):
