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 SEC 1.
____
(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 SEC1
R (1) Remove the RELAY-PITCH TRIM ACTUATOR MOTOR 2 SPLY (36CE2) (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 2 SPLY (36CE2)
- replace the SEC-1 (1CE1) (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 2 SPLY (36CE2).
(c) If the resistance is between 280 and 400 ohms:
- install the RELAY-PITCH TRIM ACTUATOR MOTOR 2 SPLY (36CE2)
- see para (3).
(3) If the fault continues:
- replace the SEC-1 (1CE1) (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.2 of the pitch trim actuator (Ref. AMM TASK 27-44-57-000-001) and (Ref. AMM TASK 27-44-57-400-001).
(5) 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).
(6) If the fault continues: R - replace the RLY-PITCH TRIM ACTR MOT 2 SPLY (36CE2) (Ref. IPC R 27920803).

Aug 01/00 CESR (7) If the fault continues:
- do a check of the wiring from the relay (36CE2), pin A/X2 to the ground (Ref. ASM 27-94/12).
- do a check of the wiring from the relay (36CE2) to the SEC 1 (1CE1), from the pin A/X1 to the pin AE/13E (Ref. ASM 27-94/12).
- do a check of the wiring from the relay (36CE2) to the ELAC 1 (2CE1), from the pin A/X1 to the pin AD/15J (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 THS actuator pin B/M to the ground (Ref. ASM 27-94/12).
- do a check of the wiring from the relay (36CE2) to the THS actuator (9CE), from the pin A/A1 to the pin B/K (Ref. ASM 27-94/12).
1 If there is no continuity, repair the wiring.
_
2 if there is continuity:
_
- do a check of the wiring from the relay (36CE2) pin A/A2 to the C/B (19CE2) (Ref. ASM 27-94/12).
a If there is no continuity, repair the wiring.
_
b if there is continuity:
_
- do a check and repair the wiring of the XDCR MON MOT 2 (V1, V2) signal, from THS actuator (9CE) to the SEC 1 (1CE1) (Ref. ASM 27-94/12).
B. Do the tests given in Para. 3.
Failure of the Override Switch 2
1. Possible Causes
_______________
- ELAC-1 (2CE1)
- wiring from the DSI-31 signal of the ELAC 1 (2CE1) to the first terminal block
- wiring from the overriding signal of the THS actuator (9CE) to the first terminal block
- pitch trim actuator
