- make sure that there is no continuity between pins AA/6G, 6H, between pins AA/6H, 6J and between pins AA/6G, 6J of the rack connector.
(1) If there is no continuity:
- install a new ADIRU1 (Ref. AMM TASK 34-12-34-400-001).
(2) If there is continuity:
- 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 ADM1 and make sure that there is no continuity between pins A/A, C, between pins A/C, E and between pins A/A, E of the ADM1.

(a) If there is continuity:
- replace the ADM1 (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001)
- install the ADIRU1.
(b) If there is no continuity:
- get access to the ADM-R STATIC PRESSURE (19FP4) and the ADM-L STATIC PRESSURE (19FP5) (Ref. AMM TASK 34-11-17-000-001) (Para. 2.B.)
- disconnect the electrical connector of the ADM4 and make sure that there is no continuity between pins A/A, C, between pins A/C, E and between pins A/A, E of the ADM4.
1_ If there is continuity:
- replace the ADM4 (Ref. AMM TASK 34-11-17-000-001) and (Ref.
AMM TASK 34-11-17-400-001)
- connect the electrical connector of the ADM1
- install the ADIRU1.
2 If there is no continuity:
_
- disconnect the electrical connector of the ADM5 and make sure that there is no continuity between pins A/A, C, between pins A/C, E and between pins A/A, E of the ADM5.
a If there is continuity:
_
- replace the ADM5
- connect the electrical connector of the ADM1 and 4
- install the ADIRU1.
b If there is no continuity:
_
- do a check and repair the aircraft wiring between ADIRU1 pins AA/6G, 6H, 6J and the related LRU (Ref. ASM 34-13/03)
- connect the electrical connector of the ADM
- install the ADIRU1.
B. Do the test given in Para. 3.

__________________
A. Test Do the Interface test of the ADR (system 2) (Ref. AMM TASK 34-13-00-740-002).
4. Fault Isolation
_______________
A. If the test gives the maintenance message ADM2 (19FP2)/ ADM6 (19FP6)/ ADM7 (19FP7):
- remove the ADIRU-2 (1FP2) (Ref. AMM TASK 34-12-34-000-001)
- make sure that there is no continuity between pins AA/6G, 6H, between pins AA/6H, 6J and between pins AA/6G, 6J of the rack connector.
(1) If there is no continuity:
- install a new ADIRU2 (Ref. AMM TASK 34-12-34-400-001).
(2) If there is continuity:
- get access to the ADM-R TOTAL PRESSURE (19FP2) (Ref. AMM TASK 34-11-17-000-001) (Para. 2.B.)
- disconnect the electrical connector of the ADM2 and make sure that there is no continuity between pins A/A, C, between pins A/C, E and between pins A/A, E of the ADM2.
