A. If the test gives the maintenance message WRG:SDI PIN PROG/ADIRU1 (1FP1):
- do a check of the SDI pin-programming pins AB/1A, 5A, 6A on the rack connector,
- compare the status of the SDI pin-programming with the status given in the ASM (Ref. ASM 34-12/01).
(1) If the pin programming is incorrect:
- repair the wiring of the defective programming pins (Ref. ASM 34-12/01).
(2) If the pin programming is correct:
- replace the ADIRU-1 (1FP1) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
