A. Test
(1) Not applicable, the fault is evident.
4. Fault Isolation
_______________
A. If the AFS/TEST REPORT page related to the FMGC 1 is not shown on the MCDU:
- 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 SIDE 1 discretes from the FMGC 1 (1CA1) to the ground points (Ref. ASM 22-84/01).

__________________
A. Test
(1) Do the Ground Scanning of the AFS (Ref. AMM TASK 22-91-00-710-001) and check of discrepency between ADR/IR parameters.
4. Fault Isolation
_______________
A. If the test gives the maintenance message AFS : ADIRU 1/2/3 DISAGREE:
- do a check of the presence, at the same time, of the message ADIRU RTOK.
(1) If there is the above mentioned message:
- no maintenance action is necessary.
(2) If there is no message:
- do the INTERFACE test of the ADR system (Ref. AMM TASK 34-13-00-740-002)
- do the INTERFACE test of the IR system (Ref. AMM TASK 34-14-00-740-001).

(a) If the test gives a new maintenance message, do the trouble shooting procedure related to the maintenance message.
(b) If the fault continues:
- do the functional test of the altitude and airspeed data (Ref. AMM TASK 34-13-00-720-009).
- do the trouble shooting related to the monitoring of the IR parameters at the end of the flight (Ref. TASK 34-14-00-810-926).
B. If the test does not confirm the fault:
- read the Post Flight Report (PFR) for maintenance messages related to the ADR with the EFCS source.
(1) If the PFR gives the maintenance message ADR1 with the EFCS source:
- do this trouble shooting procedure: (Ref. TASK 34-13-81-810-823).
(2) If the PFR gives the maintenance message ADR2 with the EFCS source:
- do this trouble shooting procedure: (Ref. TASK 34-13-81-810-824).
(3) If the PFR gives the maintenance message ADR3 with the EFCS source:
- do this trouble shooting procedure: (Ref. TASK 34-13-81-810-825).
C. Do the test given in Para. 3.
