A. Test
(1) Do the operational test of the AFS (Ref. AMM TASK 22-96-00-710-001) and read the result for the FMGC 2.
4. Fault Isolation
_______________
A. If the test gives the maintenance message AFS: FMGC2/FMGC1 BUS A WG:
- replace the FMGC-2 (1CA2), (Ref. AMM TASK 22-83-34-000-001) and (Ref. AMM TASK 22-83-34-400-001).
(1) If the fault continues:
- do a check of the wiring of the FMGC OPP A (COM) and FMGC OPP A (MON) buses (from the FMGC 2 (1CA2) to the first terminal block) (Ref. ASM 22-86/02).
(a) If there is no continuity:
- repair the above wiring.
(b) If there is continuity:
- do a check and repair the wiring of the FMGC OPP HLTY discrete (from the FMGC 2 (1CA2) to the first termi al block) (Ref. ASM 22-85/04).
