(2) If the pin programming is correct:
- get access to the ADM (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 (Ref. ASM 34-13/03).
(a) If the pin programming is incorrect:
- repair the SDI pin programming of the ADM (19FP1)
- connect the electrical connector of the ADM (19FP1)
- install the ADIRU1.
(b) If the pin programming is correct:
- install a new ADIRU1
- connect the electrical connector of the ADM (19FP1).
1 If the fault continues:
_
- replace the ADM-L TOTAL PRESSURE (19FP1) (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001).
B. Do the test given in Para. 3.

4. Fault Isolation
_______________
A. If the test gives the maintenance message WRG: BARO SOURCE SELECT PIN PROG:
- remove the ADIRU-1 (1FP1) (Ref. AMM TASK 34-12-34-000-001)
- do a check of the wiring and make sure that there is a ground signal at pin AA/7G and an open circuit at pin AA/7F on the rack connector.
(1) If the pin programming is incorrect:
- repair the aircraft wiring: defective pin
- install the ADIRU1.
(2) If the pin programming is correct:
- do a check of pin AA/3C on the rack connector
- compare the state of the pin with the BARO PORT A SELECT pin programming given in the ASM (Ref. ASM 34-12/01).
(a) If the pin programming is correct:
- install a new ADIRU1 (Ref. AMM TASK 34-12-34-400-001).
