A. Test
(1) Do a BITE test of the applicable SFCC (Ref. AMM TASK 27-81-00-740-002).
4. Fault Isolation
_______________
A. Procedure
(1) If the flap menu comes into view when the slat menu is selected:
(a) Swop the SFCC's and repeat the test in Para. 3.A. on SFCC-1 (21CV) and SFCC-2 (22CV).
(2) If the fault has moved to the other SFCC position, swop the SFCC's back and replace the SFCC that has the fault (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001).

(3) If the fault did not move to the other SFCC position, swop the SFCC's back Ref. Para. (2).
(a) Make sure that there are no landing gear system faults (Ref. ATA 32-31-00)
NOTE : Main landing gear shock absorber proximity sensor faults
____
will cause this failure.
- For SFCC1 PROX SNSR R L/G EXT 20GA and PROX SNSR L L/G EXT 21GA
- For SFCC2 PROX SNSR R L/G EXT 22GA and PROX SNSR L L/G EXT 23GA
(4) If there were any landing gear faults, do the test in Para. 3.A.
(5) If the fault continues:
(a) Swop RELAY-A/C ON GND (94CV) with RELAY-A/C ON GND (96CV)
(b) Do the test in Para. 3.A. on SFCC1 and SFCC2.
(c) If the fault moves to the other system, replace the relay in the system that now has the fault.
(d) Do the test in Para. 3.A.
(6) If the fault does not move to the other system, do a check of the aircraft wiring.
- for SFCC1 from C/B 5CV to the LGCIU1 and from the RELAY A/C ON GND 94CV to SFCC1 (Ref. ASM 27-81/02).
- for SFCC2 from C/B 7CV to the LGCIU2 and from the RELAY A/C ON GND 96CV to SFCC2 (Ref. ASM 27-81/03).
(a) Repair any defect found.
(b) Do the test in Para. 3.A.
