(2) Do the Ground Scanning of the AFS (Ref. AMM TASK 22-91-00-710-001).
(3) Close the circuit breakers 1GG and 2GG.
4. Fault Isolation
_______________
A. If the test gives the maintenance message AFS: BSCU2 (ISSUED BY: FG1):
- 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 BSCU (10GG) (Ref. AMM TASK 32-42-34-000-001) and (Ref. AMM TASK 32-42-34-400-001).
(2) If the fault continues:
- do a check and repair the wiring of the BSCU OPP VALID COM and BSCU OPP VALID MON discretes (from the FMGC 1 (1CA1) to the BSCU (10GG)) (Ref. ASM 22-85/04).
B. If the test gives the maintenance message AFS: BSCU2 (ISSUED BY: FG2):
- 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 and repair the wiring of the BSCU OWN VALID COM and BSCU OWN VALID MON discretes (from the FMGC 2 (1CA2) to the first terminal block) (Ref. ASM 22-85/04).
C. Do the test given in Para. 3.
