Loss of the Signal of the Right Yellow Elevator-Servocontrol Servovalve by the SEC 2
1. Possible Causes
_______________
- SEC-2 (1CE2)
- wiring of the R ELEV SV (ANO 2) signal from the SEC 2 (1CE2) COM part to the MON part
- wiring from the SEC 2 (1CE2) MON part, pins AD/2F, 2G to the first
terminal block

__________________
A. Test
(1) Do the operational test of the side stick assembly (Activation for the BITE test) (Ref. AMM TASK 27-96-00-710-020).
NOTE : Before you start the operational test procedure, release the
____ FLT CTL/ELAC 1 and FLT CTL/ELAC 2 pushbutton switches (on these pushbutton switches the OFF legends come on).
(2) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).

CES
4. Fault Isolation
_______________
A. If the test gives the maintenance message: SEC2 COM OR WIRING TO R Y ELEV SERVO VLV 34CE2
- replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
(1) If the fault continues:
(a) Do a check of the wiring of the R ELEV SV (ANO 2) signal from the SEC 2 (1CE2) COM part to the MON part, from the pins AA/2A, 2B to the pins AD/2J, 2K (Ref. ASM 27-94/08):
- if there is continuity, see Para. (b)
- if there is no continuity, repair the above wiring.
(b) Repair the wiring from the SEC 2 (1CE2) MON part, pins AD/2F, 2G to the first terminal block (Ref. ASM 27-94/08).
B. Do the tests given in Para. 3.
