(b) If there is continuity:
- do a check and repair the wiring of the command signal from the THS actuator (9CE) to the ELAC 2 (2CE2), (Ref. ASM 27-93/13).
(3) If the fault continues:
- 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 ELAC 2
1. Possible Causes
_______________
- ELAC-2 (2CE2)
- electronic module N.1 of the pitch trim actuator
- monitor position transducer of the THS actuator R - command position transducer of the THS actuator
- RLY-ELAC 2 SPLY (53CE)
- RLY-PITCH TRIM ACTR MOT 1 SPLY (36CE1)
- wiring from the relay (36CE1) pin A/X2 to the ground
- wiring from the relay (36CE1) to the ELAC 2 (2CE2)
- wiring from the THS actuator (9CE) pin D/E to the ground
- wiring from the relay (36CE1) to the THS actuator (9CE)
- wiring from the relay (36CE1) to the relay (53CE)
- wiring from the relay (53CE) pin A/B3 to the C/B (19CE1)
- wiring of the XDCR MON MOT 1 (V1, V2) signal R - wiring of the XDCR COM MOT 1 (V1, V2) signal

3. Fault Confirmation
__________________
A. Test
(1) Do the operational test of the THS actuator electrical control (Ref. AMM TASK 27-96-00-710-022).
NOTE : Do the ground setting only with the ELAC 2.
____
(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 ELAC2
- 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:
- replace the electronic module N.1 of the pitch trim actuator, (Ref. AMM TASK 27-44-57-000-002) and (Ref. AMM TASK 27-44-57-400-002).
(2) If the fault continues:
- replace the monitor position transducer of the THS actuator, (Ref. AMM TASK 27-44-56-000-001) and (Ref. AMM TASK 27-44-56-400-001).
R (3) If the fault continues:
R - replace the command position transducer of the THS actuator, (Ref.
R AMM TASK 27-44-56-000-001) and (Ref. AMM TASK 27-44-56-400-001).
R (4) If the fault continues:
- replace the RLY-ELAC 2 SPLY (53CE) (Ref. IPC 27920803).
R (5) If the fault continues:
- replace the RLY-PITCH TRIM ACTR MOT 1 SPLY (36CE1) (Ref. IPC 27920803).
R (6) If the fault continues :
- do a check of the wiring from the relay (36CE1) pin A/X2 to the ground, (Ref. ASM 27-93/13).
- do a check of the wiring from the relay (36CE1) to the ELAC 2 (2CE2), from the pin A/X1 to the pin AD/15J (Ref. ASM 27-93/13).
(a) If there is no continuity, repair the wiring.
(b) If there is continuity :
