_______________
A. If the test gives the maintenance message AFS : CLOCK:
- replace the FMGC-1 (1CA1), (Ref. AMM TASK 22-83-34-000-001) and (Ref. AMM TASK 22-83-34-400-001).
(1) If the fault continues:
- replace the FMGC-2 (1CA2).
(a) If the fault continues:
- do a check and repair the wiring from the FMGC 1 (1CA1) pins AA/13F, 13G to the first terminal block , (Ref. ASM 31-21/01).
