- remove the ADIRU-1 (1FP1) (Ref. AMM TASK 34-12-34-000-001)
- do a check of the SDI pin programming, 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 SDI pin programming of the ADIRU1
- install the ADIRU1 (Ref. AMM TASK 34-12-34-400-001).

(2) If the pin programming is correct:
- get access to the ADM (19FP5) (Ref. AMM TASK 34-11-17-000-001) (Para. 2.B.)
- disconnect the electrical connector of the ADM (19FP5)
- make sure that there is continuity between pins A/J, K, M, P and that there is an open circuit between pins A/L, N (Ref. ASM 34-13/03).
(a) If the pin programming is incorrect:
- repair the SDI pin programming of the ADM (19FP5)
- connect the electrical connector of the ADM (19FP5)
- install the ADIRU1.
(b) If the pin programming is correct:
- install a new ADIRU1
- connect the electrical connector of the ADM (19FP5).
1 If the fault continues:
_
- replace the ADM-L STATIC PRESSURE (19FP5) (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.
