 4. Fault Isolation
_______________

 A. If only the first test gives the maintenance message AFS: FMGC1/ATHR DISC 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 and repair the wiring of the ATH INST DISC NO discrete (from the FMGC 1 (1CA1) to the A/THR instinctive disconnect relays (5CA1 and 5CA2)) (Ref. ASM 22-31/01).
 B. If only the second test gives the maintenance message AFS: FMGC1/ATHR DISC 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 ATH INST DISC NC (from the FMGC 1 (1CA1) to the A/THR 2 instinctive disconnect relay (5CE2)) (Ref. ASM 22-31/01).
 (a) If there is no continuity:

 - repair the above wiring.

 (b) If there is continuity:


 - do a check and repair the wiring between the A/THR instinctive disconnect relays (5CA1 and 5CA2) from 5CE1 pin A/5 to 5CE2 pin A/C (Ref. ASM 22-31/01) .
 C. If the two tests give the maintenance message AFS: FMGC1/ATHR DISC 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 and repair the wiring of the GND FILTERED discrete (from the FMGC 1 (1CA1) to the A/THR 1 instinctive disconnect relay (5CA1)) (Ref. ASM 22-31/01).
 D. Do the tests given in Para. 3.

 CES  Loss of the Reception of the ATH INST DISC Discretes by the FMGC 2


 1. Possible Causes
_______________
 - FMGC-2 (1CA2)

 - wiring of the ATH INST DISC NO discrete (from the FMGC 2 (1CA2) to the A/THR instinctive disconnect relays (5CA1 and 5CA2))

 - wiring of the ATH INST DISC NC (from the FMGC 2 (1CA2) to the A/THR 2 instinctive disconnect relay (5CE2))

 - wiring between the A/THR instinctive disconnect relays (5CA1 and 5CA2)

 - wiring of the GND FILTERED discrete (from the FMGC 2 (1CA2) to the A/THR 1 instinctive disconnect relay (5CA1))

 3. Fault Confirmation
__________________
 A. Test
 (1) On the FCU, make sure that the A/THR pushbutton switch is pushed.

 (2) Do the operational tests of the AFS (Ref. AMM TASK 22-96-00-710-001) and read the result for the FMGC 2:

 (a) with one A/THR instinctive disconnect pushbutton switch pushed (on the throttle control levers).

 (b) with the two A/THR instinctive, disconnect pushbuttons switches released.
