(b) If there is continuity:
- do a check of the wiring of the DSI-49 signal from the ELAC 2 (2CE2) to the ELAC 2 (2CE2), COM part and MON part (Ref. ASM 27-93/13).
1 If there is no continuity, repair the wiring.

May 01/01 CES 2 If there is continuity:
_
- do a check of the wiring of the enable signal from the THS actuator (9CE) to the ELAC 2 (2CE2) (Ref. ASM 27-93/13).
a If there is no continuity, repair the wiring.
_
b If there is continuity:
_
- do a check and repair the wiring from the relay (36CE1) to the ELAC 2 (2CE2) and to the THS actuator (9CE) and wiring of the fault signal from the THS actuator to the ELAC 2 (2CE2) (Ref. ASM 27-93/13).
(7) If the fault continues:
R (a) Replace the pich trim actuator (Ref. AMM TASK 27-44-57-000-001) R (Ref. AMM TASK 27-44-57-400-001).
B. Do the tests given in Para. 3.
Failure of the THS Command Transducer 2
1. Possible Causes
_______________
- Command Position Transducer
- wiring of the XDCR COM SPLY signal from the THS actuator (9CE) to the first terminal block
- wiring of the XDCR COM V1, V2 signals from the THS actuator (9CE) to the first terminal block

__________________
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 1.
____
(2) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
(a) If the ground scanning gives the maintenance message: THS ACTR XDCR2 9CE
- refer to Para. Fault Isolation.
(b) If the ground scanning gives at least two maintenance messages of the list below: L B ELEV POS XDCR 34CE3 COM E1/S1 : USE STBY XDCR R B ELEV POS XDCR 34CE4 COM E1/S1 : USE STBY XDCR THS ACTR XDCR2 9CE
- do this trouble shooting procedure (Ref. TASK 27-90-00-810-819).
4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message:
THS ACTR XDCR2 9CE
- replace the Command Position Transducer, (Ref. AMM TASK 27-44-56-000-001) and (Ref. AMM TASK 27-44-56-400-001).
(1) If the fault continues:
- do the trouble shooting procedure (Ref. TASK 31-32-00-810-933) related to the ANI 2-3 analog input signal of the ELAC 1 and SEC 1 (Ref. ASM 27-93/12) and (Ref. ASM 27-94/12).
(2) If the fault continues:
- do a check of the wiring of the XDCR COM SPLY signal from the THS actuator (9CE) to the first terminal block, (Ref. ASM 27-93/12).
(a) If there is no continuity, repair the wiring.
(b) If there is continuity:
- do a check and repair the wiring of the XDCR COM V1, V2 signals from the THS actuator (9CE) to the first terminal block, (Ref. ASM 27-93/12).
B. Do the tests given in Para. 3.
