R A. If the test gives the maintenance message WRG: ZERO MACH-AOA PIN PROG:
R - remove the ADIRU-1 (2 or 3) (Ref. AMM TASK 34-12-34-000-001).
R - do a check of pin AA/5H and AA/5J on the rack connector.
R - make sure that there is no ZERO MACH-AOA pin-programming on these pins.

R (1) If the pin-programming is correct:
R - install a new ADIRU-1 (1FP1) (ADIRU-2 (1FP2) or ADIRU-3 (1FP3))
R (Ref. AMM TASK 34-12-34-400-001).

R (2) If the pin-programming is incorrect:
R - remove the wiring ZERO MACH-AOA pin-programming of the ADIRU-1 (2
R or 3) of pin AA/5H and pin AA/5J.

R B. Do the test given in Para. 3.
