May 01/00 CESR (2) If the fault continues:
- do a check of the wiring from the DSI-31 signal of the ELAC 1 (2CE1) to the first terminal block, COM part and MON part (Ref. ASM 27-93/12).
(a) If there is no continuity, repair the wiring.
(b) If there is continuity:
- do a check of the wiring from the overriding signal of the THS actuator (9CE) to the first terminal block (Ref. ASM 27-93/12).
1 If there is no continuity, repair the wiring.

2 If there is continuity:
_
- replace the pitch trim actuator (Ref. AMM TASK 27-44-57-000-001) and (Ref. AMM TASK 27-44-57-400-001).
B. Do the tests given in Para. 3.
Incorrect Position of the THS for the SEC 2
1. Possible Causes
_______________
- RELAY-PITCH TRIM ACTUATOR MOTOR 3 SPLY (36CE3)
- SEC-2 (1CE2)
- electronic module N.3 of the pitch trim actuator
- monitor position transducer of the THS actuator
- RLY-PITCH TRIM ACTR MOT 3 SPLY (36CE3)
- wiring from the relay (36CE3), pin A/X2 to the ground
- wiring from the relay (36CE3) to the SEC 2 (1CE2)
- wiring from the THS actuator pin D/J to the ground
- wiring from the relay (36CE3) to the THS actuator (9CE)
- wiring from the relay (36CE3) A/A2 to the C/B (19CE3)
- wiring of the XDCR MON MOT 3 (V1, V2) signal

(2) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message:
THS ACTR POS ERROR 9CE OF SEC2
R (1) Remove the RELAY-PITCH TRIM ACTUATOR MOTOR 3 SPLY (36CE3) (Ref. IPC R 27920803).
(2) Do a check of the resistance between pins X1 and X2.
(a) If the resistance is less than 280 ohms:
- replace the RELAY-PITCH TRIM ACTUATOR MOTOR 3 SPLY (36CE3)
- replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001) (Ref. AMM TASK 27-94-34-400-001).
(b) If the resistance is more than 400 ohms:
- replace the RELAY-PITCH TRIM ACTUATOR MOTOR 3 SPLY (36CE3).
(c) If the resistance is between 280 and 400 ohms:
- install the RELAY-PITCH TRIM ACTUATOR MOTOR 3 SPLY (36CE3)
- see para (3).
(3) If the fault continues:
- replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
(4) If the fault continues:
- replace the electronic module N.3 of the pitch trim actuator (Ref. AMM TASK 27-44-57-000-001) and (Ref. AMM TASK 27-44-57-400-001). 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 1(75)
