A. Test
(1) Do a BITE test of the applicable SFCC (Ref. AMM TASK 27-51-00-740-002).
4. Fault Isolation
_______________
A. Procedure
(1) If the flap menu is not available:
(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 SFCC 1 PROX SNSR R L/G EXT 20GA and PROX SNSR L L/G EXT 21GA
- For SFCC 2 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 the RELAY-A/C ON GND (95CV) with RELAY-A/C ON GND (97CV).
(b) Do the test in Para. 3.A. on the SFCC 1 and SFCC 2.
(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 SFCC 1 from C/B 6CV to the LGCIU 1 and from the RELAY A/C ON GND 95CV to SFCC 1 (Ref. ASM 27-51/02).
- for SFCC 2 from C/B 8CV to the LGCIU 2 and from the RELAY A/C ON GND 97CV to SFCC 2 (Ref. ASM 27-51/03).
(a) Repair any defect found.
(b) Do the test in Para. 3.A.
