AMM 27-51-00-740-002 Bite Test of the Slat and Flap Control Computers (Flap System)
3. Fault Confirmation
__________________
A. Test
(1) At the ECAM Control Panel, push the STS P/BSW to show the status page on the lower ECAM DU:
- if a FLAPS status message is not shown, there is no flaps fault
- if a FLAPS status message is shown, do the fault isolation procedure given in Para. 4.
4. Fault Isolation
_______________
A. Procedure
R (1) Make sure that the flaps control lever is in the correct detent and R reset it if necessary:
- if the FLAPS status message has gone, there is no fault
- if the FLAPS status message stays, do the next step.
NOTE : When the flaps control lever is out of detent, SFCC1 and SFCC2
____ will find that the lever position and the flap position (signal from the Valveblock PPU) disagree. The FLP 1 (2) PCU VALVEBLOCK 23CV (24CV) message will then be given by each SFCC

and the ECAM message FLAPS FAULT will be shown. This flight control configuration error can be cleared by a reset of the flaps control lever.
R R (2) Do a BITE test of the SFCC1 and SFCC2 flaps system (Ref. AMM TASK 27-51-00-740-002): - if the test gives a fault message, do the trouble shooting procedure related to this message.
Flaps - SFCC 1 (2) Gives PCU Valveblock 23CV (24CV) Valve Sensor Message

(3) Select <SFCC/TEST, to do the SFCC BITE test:
- if the fault message FLP1 (2) PCU VALVEBLOCK 23CV (24CV) VALVE SENSOR 27-54-53 is shown, do the Fault Isolation Procedure given in Para. 4.
NOTE : This message is not a CFDS Normal Mode message and is only

shown in SFCC reports.
4. Fault Isolation
_______________
A. Procedure
(1) Interchange the SFCC1 and SFCC2 (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001).
(2) Do the test given in Para. 3.A:
(a) If the fault goes, replace the initial SFCC-1 (21CV) or SFCC-2 (22CV), (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001). 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 飞行操纵 2(17)
