1_ If there is no continuity, repair the wiring.
2_ If there is continuity : - do a check of the wiring from the relay (36CE1) to the relay (53CE) from the pin A/A2 to the pin A/B2 (Ref. ASM 27-93/13). - do a check of the wiring from the relay (53CE) pin A/B3 to the C/B (19CE1) (Ref. ASM 27-93/13).
a_ If there is no continuity, repair the wiring.
R R R b_ If there is continuity : - do a check and repair the wiring of the XDCR MON MOT 1 (V1, V2) signal, from the THS actuator (9CE) to the ELAC 2 (2CE2) (Ref. ASM 27-93/13). - do a check and repair the wiring of the XDCR COM MOT 1 (V1, V2) signal, from the THS actuator (9CE) to the ELAC 2 (2CE2) (Ref. ASM 27-93/13).
B. Do the tests given in Para. 3.
Failure of the THS Actuator Servo Motor 1
1. Possible Causes
_______________
- RELAY-PITCH TRIM ACTUATOR MOTOR 1 SPLY (36CE1)
- ELAC-2 (2CE2) R
- Electronic module 1
- wiring of the K3-1 signal from the ELAC 2 (2CE2) to the first terminal block
- wiring of the DSI-49 signal from the ELAC 2 (2CE2) to the ELAC 2 (2CE2)
- wiring of the enable signal from the THS actuator (9CE) to the ELAC 2 (2CE2)
- wiring from the relay (36CE1) to the ELAC 2 (2CE2) and to the THS actuator (9CE)
- wiring of the fault signal from the THS actuator to the ELAC 2 (2CE2) R - pich trim actuator

(2) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
NOTE : Wait 60 seconds before you start the BITE test.
____
4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message:
THS ACTR SERVO MOT1 9CE
(1) Remove the RELAY-PITCH TRIM ACTUATOR MOTOR 1 SPLY (36CE1) (Ref. IPC 27920803).
(2) Do a check of the resistance between pins X1 and X2 of the relay.
(a) If the resistance is less than 280 ohms:
- replace the RELAY-PITCH TRIM ACTUATOR MOTOR 1 SPLY (36CE1)
- replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
(b) If the resistance is more than 400 ohms:
- replace the RELAY-PITCH TRIM ACTUATOR MOTOR 1 SPLY (36CE1).
(c) If the resistance is between 280 and 400 ohms:
- install the RELAY-PITCH TRIM ACTUATOR MOTOR 1 SPLY (36CE1)
- see Para (3).
(3) If the fault continues:
- replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
(4) If the fault continues:
R - replace the RELAY-PITCH TRIM ACTUATOR MOTOR 1 SPLY (36CE1) (Ref. IPC 27920803).
(5) If the fault continues:
- replace the Electronic module 1 (Ref. AMM TASK 27-44-57-000-002) and (Ref. AMM TASK 27-44-57-400-002).
(6) If the fault continues:
- do a check of the wiring of the K3-1 signal from the ELAC 2 (2CE2) to the first terminal block, COM part and MON part, (Ref. ASM 27-93/13).
