Loss of the Pitch Change Over Signal by the ELAC 2
 1. Possible Causes
_______________
 - ELAC-2 (2CE2)

 - wiring of the PITCH AXIS OK (DSO 01) signal from the ELAC 2 COM part to the MON part (DSI 29)

 - wiring of the PITCH AXIS OK (DSO 09) signal from the ELAC 2 COM part to the MON part (DSI 12)

 - wiring of the PITCH AXIS OK (DSO 01) signal from the ELAC 2 MON part to the COM part (DSI 29)

 - wiring of the PITCH AXIS OK (DSO 09) signal from the ELAC 2 MON part to the COM part (DSI 12)

 A. Test
 (1) 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 CHECK PITCH CHANGE OVER WIRING OF ELAC2:
 - replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
 (1) If the fault continues:
 (a) Do the trouble shooting procedure (Ref. TASK 31-32-00-810-932) related to the:
 - PITCH AXIS OK (DSO 01) signal ELAC 2 COM part (Ref. ASM 27-92/32)

 - PITCH AXIS OK (DSO 09) signal ELAC 2 COM part (Ref. ASM 27-92/32)

 - PITCH AXIS OK (DSO 09) signal ELAC 2 MON part (Ref. ASM 27-92/32)

 (2) If the fault continues:
 (a) Do a check of the wiring of the PITCH AXIS OK (DSO 01) signal from the ELAC 2 COM part to the MON part (DSI 29) (Ref. ASM 27-92/32).

 - if there is continuity, see Para. (b)

 - if there is no continuity, repair the above wiring.

 (b) Do a check of the wiring of the PITCH AXIS OK (DSO 09) signal from the ELAC 2 COM part to the MON part (DSI 12) (Ref. ASM 27-92/32).

 - if there is continuity, see Para. (c)

 - if there is no continuity, repair the above wiring.

 (c) Do a check of the wiring of the PITCH AXIS OK (DSO 01) signal from the ELAC 2 MON part to the COM part (DSI 29) (Ref. ASM 27-92/32).

 - if there is continuity, see Para. (d)

 - if there is no continuity, repair the above wiring.

 (d) Do a check and repair the wiring of the PITCH AXIS OK (DSO 09) signal from the ELAC 2 MON part to the COM part (DSI 12) (Ref. ASM 27-92/32).

 B. Do the test given in Para. 3.
