(a) The BITE gives a "WTBs set in this channel"
(2) Do the detailed inspection of the PCU (Ref. AMM TASK 27-54-00-200-001)).
(a) During the inspection at Para 4.A.(2).
- refer to (Ref. AMM TASK 27-51-19-000-001) Figure 402 and identify the FPPU:
- do a check of the FPPU zero datum mark.
- if the zero datum marks are NOT aligned. Do (Ref. AMM TASK 27-51-00-820-001).
- if the zero datum is set
- do the reset of the wing tip brakes (Ref. AMM TASK 27-50-00-869-006)
(3) Do the operational test of the flap system, (Ref. AMM TASK 27-54-00-710-001).
(4) Access the FLP ON GROUND FAULTS and check that the ground log is clear.

3. Fault Confirmation
__________________
A. Test
(1) Do a BITE test with the LGCIU given in the CFDS message (Ref. AMM TASK 32-69-00-740-001).
(2) If the test gives a message that includes the DISC PROX SENSOR (38CV or 40CV), do the fault isolation procedure in (Ref. TASK 32-31-00-810-829).
(3) If the test does not give a message that includes the DISC PROX SENSOR (38CV or 40CV), but the fault continues, do the fault isolation procedure in Para. 4.
4. Fault Isolation
_______________
A. Procedure
(1) Interchange the SFCCs, use (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001).
NOTE : This will cause each SFCC to get a new identification.
____
(2) Do an operational test of the flap interconnecting strut (Ref. AMM TASK 27-51-00-710-002).
(3) If the test is OK:
(a) Replace the SFCC-1 (21CV) or SFCC-2 (22CV) that was the source of the initial CFDS message.
(4) If the test is not OK (gives the same CFDS message as the initial CFDS message):
(a) Replace the applicable proximity sensor SENSOR-R FLAP ATTACHMENT FAILURE DETECTION (38CV) or SENSOR-R FLAP ATTACHMENT FAILURE DETECTION (40CV), (Ref. AMM TASK 27-51-15-000-002) and (Ref. AMM TASK 27-51-15-400-002).
(5) If the fault continues, do a check and repair as necessary the aircraft wiring between:
- the applicable proximity sensor and the related LGCIU, (Ref. ASM 27-51/06) or (Ref. ASM 27-51/07)
- the applicable LGCIU and the related SFCC, (Ref. ASM 27-51/06) or (Ref. ASM 27-51/07). 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 1(102)
