3. Fault Confirmation
__________________
A. 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:
ELAC1 OR BUS FROM ELAC2
- replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
(1) If the fault continues:
- replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
(2) If the fault continues:
(a) Do a check of the wiring of the DGO 05 signal from the ELAC 2 (2CE2) COM part to the ELAC 1 (2CE1) (Ref. ASM 27-92/52).
- if there is no continuity, repair the above wiring
- if there is continuity, see Para. (b).
(b) Do a check and repair the wiring of the DGO 05 signal from the ELAC 2 (2CE2) MON part to the ELAC 1 (2CE1) (Ref. ASM 27-92/52).
