4. Fault Isolation
_______________
A. If the test gives the maintenance message ADR3 BUS 3:
- do the interface test of the IR (system 1) (Ref. AMM TASK 34-14-00-740-001).
(1) If the test gives the maintenance message ADIRU3 (1FP3)/ADIRU1 (1FP1):
- replace the ADIRU-3 (1FP3) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
(a) If the fault continues:
- do a check and repair the wiring of the ADR OUTPUT BUS 3 bus from the ADIRU 3 (1FP3) to the first terminal block (Ref. ASM 34-13/01).
(2) If the test does not give the maintenance message ADIRU3 (1FP3)/ADIRU1 (1FP1):
- do a check and repair the wiring between the terminal blocks 1510VT and 1851VT: between pins 2Y, 3Y and 43E, 44E (Ref. AWM 34-11-26).
