A. If the fault symptom is identified by the maintenance message on the face of the ISIS indicator: ADIRU1(1FP1) BUS IR/ISIS(22FN-10FC)
- do the interface test of the IR (system 1) (Ref. AMM TASK 34-14-00-740-001).
(1) If the test gives a maintenance message, do the trouble shooting procedure related to the maintenance message.
(2) If the test is OK:
- do a check of the wiring of the ADIRU 1 BUS 2 IR from the ISIS indicator (22FN) to the ADIRU 1 (1FP1) (Ref. ASM 34-22/02).
(a) If there is no continuity:
- replace the defective wiring.

1_ After the subsequent flight, if the fault continues:
- replace the ADIRU-1 (1FP1) (Ref. AMM TASK 34-12-34-000-001)
(Ref. AMM TASK 34-12-34-400-001).

4. Fault Isolation
_______________
A. If the fault symptom is identified by the maintenance message on the face of the ISIS indicator: ADIRU3(1FP3) BUS IR/ISIS(22FN-10FC) and by the red flag on the face of the ISIS indicator: HDG
- do the interface test of the IR (system 3) (Ref. AMM TASK 34-14-00-740-001).
(1) If the test gives a maintenance message, do the trouble shooting procedure related to the maintenance message.
(2) If the test is OK:
- do a check of the wiring of the ADIRU 3 BUS 2 IR from the ISIS indicator (22FN) to the ADIRU 3 (1FP3) (Ref. ASM 34-22/02).
(a) If there is no continuity:
- replace the defective wiring.
