- replace the FMGC-2 (1CA2) (Ref. AMM TASK 22-83-34-000-001) and (Ref. AMM TASK 22-83-34-400-001).
(2) If the fault continues:
- do a check and repair the wiring of the ADC ADIRS OWN and the IRS ADIRS OWN bus from the FMGC 2 (1CA2) to the first terminal block (Ref. ASM 22-86/01).
E. Do the test given in Para. 3.

1. Possible Causes
_______________
- FAC-1 (1CC1)
- FAC-2 (1CC2)
- FMGC-1 (1CA1)
- FMGC-2 (1CA2)
- rejection of ADR parameters due to excessive offset
- wiring of the ADC ADIRS 3 and the IRS ADIRS 3 bus from the FAC 1 (1CC1) to the first terminal block
- wiring of the ADC ADIRS 3 and the IRS ADIRS 3 bus from the FAC 2 (1CC2) to the first terminal block
- wiring of the ADC ADIRS 3 and the IRS ADIRS 3 bus from the FMGC 1 (1CA1) to the first terminal block
- wiring of the ADC ADIRS 3 and the IRS ADIRS 3 bus from the FMGC 2 (1CA2) to the first terminal block

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: ADIRU3 (ISSUED BY: FAC1):
- do the Functional Check of the Altitude/Airspeed Data (Ref. AMM TASK 34-13-00-720-009) to check if there is rejection of ADR parameters due to excessive offset.
(1) If the fault continues:
- replace the FAC-1 (1CC1) (Ref. AMM TASK 22-66-34-000-002) and (Ref. AMM TASK 22-66-34-400-002).
(2) If the fault continues:
- do the monitoring of the AOA sensors (Ref. TASK 34-11-00-810-861).
(3) If the fault continues:
- do a check and repair the wiring of the ADC ADIRS 3 and the IRS ADIRS 3 bus from the FAC 1 (1CC1) to the first terminal block (Ref. ASM 22-69/01).
