START A TASK ON OR NEAR:

- THE FLIGHT CONTROLS

- THE FLIGHT CONTROL SURFACES

- THE LANDING GEAR AND THE RELATED DOORS

- COMPONENTS THAT MOVE.

1. Possible Causes
_______________
- SFCC-1 (21CV)

- SFCC-2 (22CV)

- aircraft wiring between the CFDIU ARINC connector and the SFCC 1 (2) ARINC electrical connecter.

3. Fault Confirmation
__________________
A. Message Analysis.
(1) This fault conformation is for the SFCC 1 and SFCC 2.

(a) For the CFDIU BUS 3 and the CFDIU BUS 4 data transmission faults , refer to Page Block 101 chapter 31-32-00.

(2) The fault message is generated by SFCC 1 (2) if the CFDIU BUS#3 (CFDIU BUS#4) supplies no data.

(a) Set the MCDU to MENU MODE and access the FLAP ARINC INPUT STATUS page.

(b) If the CFDIU displays the message 'WAIT FOR SYSTEM RESPONSE'on the MCDU scratchpad and then replaces the message with 'NO RESPONSE PRESS RETURN>

(d) If access to the SFCC 1 (2) SYSTEM DATA is possible.

(e) Access the FLAP ARINC INPUT STATUS page.

(f) If the FLAP ARINC INPUT STATUS page shows CFDIU LABEL *** NO DATA do the fault isolation.

(g) If the FLAP ARINC INPUT STATUS page shows CFDIU OK do the SFCC Reset and Initialization.Para.4.A. and 4.B.

(h) Set the MCDU to MENU MODE and access the FLAP ON GROUND FAULTS page and make sure that the ground log is clear.

(i) No further maintenance is necessary.
