A. If the test gives the maintenance message WRG: ACFT IDENT PIN PROG:
- remove the ADIRU-3 (1FP3) (Ref. AMM TASK 34-12-34-000-001)
- do a check of the aircraft identification-code programming-pins AA/1E, 1F, 1G, 1H, 1J, 1K, 2E, 4A, 4B on the rack connector
- compare the state of the aircraft identification-code pin-programming with the state given in the ASM (Ref. ASM 34-12/03).
(1) If the pin-programming is incorrect:
- repair the defective wiring of the rack connector
- install the ADIRU3 (Ref. AMM TASK 34-12-34-400-001).
(2) If the pin-programming is correct:
- install a new ADIRU3.

R **ON A/C 001-049, 101-105, 151-199, 201-203,
A. If the test gives the maintenance message WRG: SDI PIN PROG:
- remove the ADIRU-1 (1FP1), (Ref. AMM TASK 34-12-34-000-001)
- do a check of pins AB/1A,5A,6A on the rack connector.
- compare the state of the pins with the SDI PIN PROGRAMMING given in the ASM (Ref. ASM 34-12/01).
(1) If the pin programming is incorrect:
- repair the aircraft wiring: defective pins
- install the ADIRU1 (Ref. AMM TASK 34-12-34-400-001).

May 01/05 CES (2) If the pin programming is correct:
- swap the ADIRU1 and the ADIRU2.
(a) If the fault stops:
- replace the ADIRU that you installed on side 2.
(b) If the fault continues:
- get access to the ADM-L TOTAL PRESSURE (19FP1) (Ref. AMM TASK 34-11-17-000-001) (Para. 2.B.)
- disconnect the electrical connector of the ADM (19FP1)
- make sure that there is continuity between pins A/J,K and that there is an open circuit between pins A/L,M,N,P.
1 If the pin programming is incorrect:
_
- repair the aircraft wiring (Ref. ASM 34-13/03)
- connect the electrical connector of the ADM (19FP1)
- install the ADIRU1.
2 If the pin programming is correct:
_
- get access to the ADM-R STATIC PRESSURE (19FP4) ADM-L STATIC PRESSURE (19FP5), (Ref. AMM TASK 34-11-17-000-001) (Para. 2.B.)
- disconnect the electrical connector of the ADM (19FP4) 中國航空網(wǎng) www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320 Trouble Shooting Manual 排故手冊 導(dǎo)航 NAVIGATION 1(112)
