A. If the test gives the maintenance message WRG: SDI PIN PROG/ ADIRU3 (1FP3):
- remove the ADIRU-3 (1FP3), (Ref. AMM TASK 34-12-34-000-001)
- do a check of 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 34-12/03).
(1) If the pin programming is incorrect:
- repair the aircraft wiring: defective pins
- install the ADIRU3 (Ref. AMM TASK 34-12-34-400-001).
(2) If the pin programming is correct:
- swap the ADIRU3 and the ADIRU1.
(a) If the fault stops:
- replace the ADIRU that you installed on side 2.
(b) If the fault continues:
- 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 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.
1 If the pin programming is incorrect:
_
- repair the aircraft wiring (Ref. ASM 34-13/03)
- connect the electrical connector of the ADM (19FP1)
- install the ADIRU3.
2 If the pin programming is correct:
_
- get access to the ADM-R STATIC PRESSURE (19FP4) ADM-L STATIC PRESSURE (19FP5), (Ref. AMM TASK 34-11-17-000-001) (Para. 2.B.)
- disconnect the electrical connector of the ADM (19FP4)
- make sure that there is continuity between pins A/J,K,N,P and that there is an open circuit between pins A/L,M.
a If the pin programming is incorrect:
_
- repair the aircraft wiring
- connect the electrical connector of the ADM (19FP4)
- install the ADIRU3.
b If the pin programming is correct:
_
- 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.
- If the pin programming is incorrect: repair the aircraft wiring connect the electrical connector of the ADM (19FP5)
