B. Test
(1) Do the Ground Scanning of the AFS (Ref. AMM TASK 22-91-00-710-001).
4. Fault Isolation
_______________
A. If the test gives the maintenance message AFS: CHK DMC2-FMGC1 CKT:
- 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 DMC-2 (1WT2) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
