3. Fault Confirmation
__________________
A. Test
(1) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
4. Fault Isolation
_______________
A. If the test confirms the fault:
- do the operational test of the SEC2 (Ref. AMM TASK 27-94-00-710-003) to make sure that the SEC2 servoes its associated surfaces.
(1) If the flight controls move according to the SEC2 servoing:
(a) Remove the SEC2 (Ref. AMM TASK 27-94-34-000-001).
(b) At the SEC2 receptacle, do a check of the resistance between pin AB/12K and pin AE/12A (Ref. ASM 27-92/05).
1 If the resistance is less than 280 ohms:
_
a Remove the RELAY-SEC 2 ANN SPLY (41CE2) (Ref. IPC
_
27920803).
b Do a check of the resistance of the relay between pin X1
_
and X2.
- If the resistance is less than 280 Ohms: . replace the RELAY-SEC 2 ANN SPLY (41CE2) (Ref. IPC 27920803) . replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-400-001).
- If the resistance is between 280 and 400 ohms: . do a check and repair the wiring of the RLY SEC FAULT signal from the relay to the SEC (Ref. ASM 27-92/05) . stall the relay . replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-400-001).
2 If the resistance is more than 400 ohms:
_
a Remove the relay (41CE2).
_
b Do a check of the resistance of the relay between pin X1
_
and X2.
- If the resistance is more than 400 ohms: . replace the RELAY-SEC 2 ANN SPLY (41CE2) (Ref. IPC 27920803) . install the SEC 2 (Ref. AMM TASK 27-94-34-400-001). If the resistance is between 280 and 400 ohms: . do a check and repair the wiring of the RLY SEC FAULT signal from the relay to the SEC (Ref. ASM 27-92/05)

. install the relay (41CE2).
. install the SEC 2 (Ref. AMM TASK 27-94-34-400-001).
3 If the resistance is between 280 and 400 ohms:
_
a Remove the FCDC-1 (3CE1) (Ref. AMM TASK 27-95-34-000-001).
_
- if the warning SEC 2 stays, install the FCDC-1 (3CE1) (Ref. AMM TASK 27-95-34-400-001) and see Para. b_.
- if the warning SEC 2 goes off, replace the FCDC-1 (3CE1) (Ref. AMM TASK 27-95-34-000-001) and (Ref. AMM TASK 27-95-34-400-001).
- install the SEC 2 (Ref. AMM TASK 27-94-34-400-001).
b Remove the FCDC-2 (3CE2) (Ref. AMM TASK 27-95-34-000-001).
_
- if the warning SEC 2 stays, install the FCDC-2 (3CE2) (Ref. AMM TASK 27-95-34-400-001) and see Para. c_.
- if the warning SEC 2 goes off, replace the FCDC-2 (3CE2) (Ref. AMM TASK 27-95-34-000-001) and (Ref. AMM TASK 27-95-34-400-001). 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 3(122)
