1. Open the circuit breaker (5FP3). - on the upper ECAM DU, the NAV ADR 3 FAULT warning comes into view
- on the ADIRS CDU, the FAULT legend of the ADR3 annunciator comes on.
4. Fault Isolation
_______________
A. If the FAULT legend of the ADR3 annunciator does not come on:
- on the panel 25VU, set the INT LT/ANN LT switch to TEST and make sure that the FAULT legend comes on.
(1) If the FAULT legend comes on:
- 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 legend stays off while the ECAM warning is shown:
- replace the BOARD-ANN LT TEST & INTFC (4LP) (Ref. AMM TASK 33-14-33-000-001) and (Ref. AMM TASK 33-14-33-400-001).
1 If the fault continues:
_
- do a check and repair the wiring of the ADR FAULT WARN discrete from the ADIRU3 (1FP3) to the annunciator light test and interface board (4LP) (Ref. ASM 34-13/02).
