Aug 01/05 CES B. Aircraft Maintenance Configuration
(1) Do the EIS start procedure (Ref. AMM TASK 31-60-00-860-001).
(2) Make sure that the two FDs are engaged (if they are not engaged, push the FD pushbutton switches on the FCU).
C. Test
(1) Open the circuit breaker 10CA1 and make sure that the FD 2 indication comes into view on the PFD 1.
(2) Close the circuit breaker 10CA1.
(3) Do the operational test of the AFS (Ref. AMM TASK 22-96-00-710-001) and read the result for the FMGC 1.
4. Fault Isolation
_______________
A. If the FD 2 indication does not come into view on the PFD 1 and if the test gives the maintenance message AFS: FMGC1/FMGC2 (FD CKT):
- 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 FD OWN ENGD MON OPP discrete (from the FMGC 2 (1CA2) to the first terminal block), (Ref. ASM 22-85/02).
B. If the FD 2 indication does not come into view on the PFD 1 and if no messages come into view after the test:
- replace the DMC-1 (1WT1), (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
(1) If the fault continues:
- do a check and repair the wiring of the FD 2 ENGD from the DMC 1 (1WT1) to the first terminal block, (Ref. ASM 22-85/02).
C. If the FD 2 indication comes into view on the PFD 1 and if the test gives the maintenance message AFS: FMGC1/FMGC2 (FD 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:
- do a check of the wiring of the FD OPP ENGD MON discrete (from the FMGC 1 (1CA1) to the first terminal block), (Ref. ASM 22-85/02).
(a) If there is no continuity:
- repair the above wiring.

(b) If there is continuity: - do a check and repair the wiring of the FD OPP ENGD COM discrete (from the FMGC 1 (1CA1) to the FMGC 2 (1CA2)), (Ref. ASM 22-85/02).
D. Do the test given in Para. 3.
R 5. Close-up________
R A. Put the aircraft back to its initial configuration.
R (1) Close the circuit breaker 10CA1.
R R (2) De-energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-862-002).
