1_ First case:
Combination of maintenance messages of the first list, do this
trouble shooting procedure (Ref. TASK 27-90-00-810-814).
2_ Second case:
Combination of maintenance messages of the second list, do
this trouble shooting procedure (Ref. TASK 27-90-00-810-815).
3_ Third case:
Combination of maintenance messages of the first and second
lists, do this trouble shooting procedure (Ref. TASK 27-90-00-
810-816).
4. Fault Isolation
_______________
A. If the test gives the maintenance message: ELAC 2 OR WIRING FROM L B ELEV MODE XDCR 34CE3
- replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
(1) If the fault continues:
- do a check and repair the wiring of the MODE XDCR (ANI 7-1) signal from the ELAC 2 (2CE2) MON part to the first terminal block (Ref. ASM 27-93/08).
B. Do the test given in Para. 3.

4. Fault Isolation
_______________
A. If the tests give the maintenance message L B ELEV MODE VLV 34CE3:
(1) Remove RELAY-THS MOT 3 INHIBITION 1 (51CE) and RELAY-THS MOT 3 INHIBITION 2 (52CE) (Ref. IPC 27920803).
(2) Do a check of the resistance between pins X1 and X2 of the relays.
(a) If the resistance is less than 280 ohms:
- replace the RELAY-THS MOT 3 INHIBITION 1 (51CE) and/or RELAY-THS MOT 3 INHIBITION 2 (52CE). 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(26)
