-----------------------------------ACTION ----------------------------RESULT ----------------
-------------------------------------------------------------------------------
1. Open the circuit breakers (4FP3) - on the upper ECAM DU, the NAV IR 3 and (6FP3) FAULT warning comes into view
- on the ADIRS CDU, the FAULT legend of the IR 3 annunciator comes on.
4. Fault Isolation
_______________
A. If the FAULT legend of the IR 3 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 IR FAULT WARN discrete from the ADIRU3 (1FP3) to the annunciator light test and interface board (4LP) (Ref. ASM 34-14/02).

Aug 01/05 CES (2) If the FAULT legend does not come on:
- 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):
(a) If the fault continues:
- replace the CDU-ADIRS (2FP) (Ref. AMM TASK 34-12-12-000-001) and (Ref. AMM TASK 34-12-12-400-001).
1_ If the fault continues:
- do a check and repair the wiring of the annunciator light
test and interface board (4LP)
. from pin A/18 to ADIRS CDU (2FP) pin C/17
. from pin A/34 to the ground point (Ref. ASM 34-14/02).
B. Do the test given in Para. 3.C.
5. Close-up
________
A. Put the aircraft back to its initial configuration.
(1) Close the circuit breakers (4FP3) and (6FP3).
(2) On the panel 25VU, set the ANN LT switch to BRT.
(3) Do the ADIRS stop procedure (Ref. AMM TASK 34-10-00-860-005). 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 导航 NAVIGATION 2(55)
