3. Fault Confirmation
__________________
A. SFCC system peripherals test.
(1) Do the SFCC1 (2) SYSTEM TEST (BITE) (Ref. AMM TASK 27-51-00-740-002). The fault data "FPPU disconnected or faulty and WTB's set" is displayed. Page block 301 Table 7 gives the SFCC test menu selection details.
(2) Do the fault isolation.
4. Fault Isolation
_______________
A. Open, safety and tag this(these) circuit breaker(s):
-------------------------------------------------------------------------------PANEL DESIGNATION IDENT. LOCATION -------------------------------------------------------------------------------49VU FLIGHT CONTROLS/FLP/CTL AND MONG/SYS1 6CV B07 121VU FLIGHT CONTROLS/FLP/CTL AND/MONG/SYS2 8CV Q21
B. Procedure
(1) Go to the maintenance procedure (Ref. AMM TASK 27-51-19-000-001) Figure 401/TASK 27-51-19 991 001 and find the FPPU 27CV (27CV).
(a) Swap the connectors 27CV-A and 27CV-B.
(b) Remove the safety clips and the tags and close the circuit breakers Ref.Para 4.A.
(c) Wait 60 seconds for SFCC initialization.
(d) Set the MENU MODE and access the FLP ON GROUND FAULTS and check the ground log.
(e) If the fault moves to SFCC 1 (2). Swap back the connectors 27CV-B and 27CV-A.
(f) Replace the 27CV (27CV), (Ref. AMM TASK 27-51-19-000-001) (Ref. AMM TASK 27-51-19-400-001)
(2) If the fault does not move
(3) Open, safety and tag the circuit breakers Ref.Para 4.A.
(4) Use ARINC connector breakout box and do a check of the aircraft wiring. Between the SFCC 1 (2) and the FPPU (Ref. ASM 27-51/06) (Ref. ASM 27-51/07)
(5) Do the repair

(6) Connect the electrical connectors 27CV-A and 27CV-B to the FPPU.
(7) Remove the safety clips and the tags and close the circuit breakers Ref.Para.4.A.
(8) Wait 60 seconds for SFCC initialization.
(9) Set the MENU MODE and access the FLP ON GROUND FAULTS and check that the ground log is clear.
5. Close-up
________
A. Remove the ground support and maintenance equipment, the special and standard tools and all other items.
B. Put the aircraft back to its initial configuration.
