__________________
A. Test Do the Interface test of the ADR (system 3) (Ref. AMM TASK 34-13-00-740-002).
4. Fault Isolation
_______________
A. If the test gives the maintenance message ADM3 (19FP3)/ ADM8 (19FP8):
- get access to the total pressure ADM (19FP3) (Ref. AMM TASK 34-11-17-000-001) (Para. 2.B.)
- disconnect the electrical connector of the ADM (19FP3)
- make sure that there is continuity between pins A/J, K, L, P and that there is an open circuit between pins A/M, N (Ref. ASM 34-13/03).
(1) If the pin programming is incorrect:
- repair the SDI pin programming of the ADM (19FP3)
- connect the electrical connector of the ADM (19FP3).
(2) If the pin programming is correct:
- get access to the static pressure ADM (19FP8) (Ref. AMM TASK 34-11-17-000-001) (Para. 2.B.)
- disconnect the electrical connector of the ADM (19FP8)
- make sure that there is continuity between pins A/J, K, L, M, N, P.

(a) If the pin programming is incorrect:
- repair the SDI pin programming of the ADM (19FP8)
- connect the electrical connectors of the ADM (19FP3) and ADM (19FP8).
(b) If the pin programming is correct:
- replace the ADM-STBY TOTAL PRESSURE (19FP3) (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001).
- connect the electrical connector of the ADM (19FP8).
1 If the fault continues:
_
- replace the ADM-STBY STATIC PRESSURE (19FP8).
B. Do the test given in Para. 3.

4. Fault Isolation
_______________
A. If the test gives the maintenance message
ADIRU1 (1FP1)/ WRG: ADM DC SUPPLY TO ADM:
- replace the ADIRU-1 (1FP1), (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
(1) If the fault continues:
- remove the ADIRU1
- do a check and repair the wiring between the ADIRU1 and the first terminal block: pins AA/6G, 6H, 6J of the ADIRU1 (Ref. ASM 34-13/03).
- install the ADIRU1.
B. Do the test given in Para. 3.
