3. Fault Confirmation
__________________
A. Job Set-Up
(1) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(2) On the overhead panel 20VU:
- on the ADIRS CDU, set the OFF/NAV/ATT selector switches to NAV and align the IRs (Ref. AMM TASK 34-10-00-860-004).
(3) On the overhead panel 23VU:
- make sure that the FLT CTL/SEC1 pushbutton switch is pushed (on this pushbutton switch, the OFF legend is off).
(4) On the overhead panel 24VU:
- make sure that the FLT CTL/ELAC2, FLT CTL/SEC2 and FLT CTL/SEC3 pushbutton switches are pushed (on these pushbutton switches, the OFF legends are off).
(5) On the overhead panel 23VU:
- release the FLT CTL/ELAC1 pushbutton switch (on this pushbutton switch, the OFF legend comes on).
(6) Pressurize the aircraft hydraulic systems (Ref. AMM TASK 29-10-00-863-003), (Ref. AMM TASK 29-23-00-863-001), (Ref. AMM TASK 29-24-00-863-001).
B. Test
(1) On the FCU:
- push the AP1 pushbutton switch to engage the AP1
- push the AP2 pushbutton switch to engage the AP2.
(2) Do the BITE test of the EFCS (Ground Scanning) (Ref. AMM TASK 27-96-00-740-001).
(3) Depressurize the aircraft hydraulic systems (Ref. AMM TASK 29-10-00-864-003), (Ref. AMM TASK 29-23-00-864-001), (Ref. AMM TASK 29-24-00-864-001).
4. Fault Isolation
_______________
A. If the F/CTL ELAC2 FAULT warning comes into view 1 second after the AP1 engagement:
(1) Replace the FMGC-1 (1CA1) (Ref. AMM TASK 22-83-34-000-001) and (Ref. AMM TASK 22-83-34-400-001).
(2) 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).
