(a) If there is continuity:

 - replace the ADM2 (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001)

 - install the ADIRU2.

 (b) If there is no continuity:

 - get access to the ADM-R STATIC PRESSURE (19FP6) and the ADM-L STATIC PRESSURE (19FP7) (Ref. AMM TASK 34-11-17-000-001) (Para. 2.B.)

 - disconnect the electrical connector of the ADM6 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 ADM6.

 1_ If there is continuity:
 - replace the ADM6 (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 ADIRU2.

 2 If there is no continuity:
_
 - disconnect the electrical connector of the ADM7 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 ADM7.
 a If there is continuity:
_
 - replace the ADM7

 - connect the electrical connector of the ADM2 and 6

 - install the ADIRU2.

 b If there is no continuity:
_
 - do a check and repair the aircraft wiring between ADIRU2 pins AA/6G, 6H, 6J and the related LRU (Ref. ASM 34-13/03)

 - connect the electrical connector of the ADM

 - install the ADIRU2.

 B. Do the test given in Para. 3.

 4. Fault Isolation
_______________
 A. If the test gives the maintenance message ADM3 (19FP3)/ ADM8 (19FP8):
 - remove the ADIRU-3 (1FP3) (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 ADIRU3 (Ref. AMM TASK 34-12-34-400-001).

 (2) If there is continuity:

 - get access to the ADM-STBY TOTAL PRESSURE (19FP3) (Ref. AMM TASK 34-11-17-000-001) (Para. 2.B.)

 - disconnect the electrical connector of the ADM3 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 ADM3.
