- if there is continuity, see Para. (b)
- if there is no continuity, repair the above wiring.
(b) Do a check of the wiring from the ELAC 2 (2CE2) COM part to the MON part, from pins AA/3J, 3K to pins AD/3B, 4B (Ref. ASM 27-93/08):
- if there is continuity, see Para. (c)
- if there is no continuity, repair the above wiring.
(c) Repair the wiring from the ELAC 2 (2CE2) MON part, pins AD/3D, 4D to the first terminal block (Ref. ASM 27-93/08).

Loss of the Signal of the Right Yellow Elevator-Servocontrol Servovalve by the ELAC 2
1. Possible Causes
_______________
- ELAC-2 (2CE2)
- XDCR UNIT-ELEV POS, R (49CE2)
- SERVO CTL-R ELEVATOR, INBD Y (34CE2)
- servovalve
- wiring of the LVDT POS (ANI 3-2) signal from the ELAC 2 (2CE2) to the first terminal block
- wiring of the POS RVDT MON signal from the transducer unit (49CE2) to the ELAC 2 (2CE2)
