 A. If the test gives the maintenance message WRG : SDI PIN PROG:
 - 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 34-12/02).

 (1) If the pin programming is incorrect:

 - repair the wiring of the defective programming pins (Ref. ASM 34-12/02).

 (2) If the pin programming is correct:

 - replace the ADIRU-2 (1FP2) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
 B. Do the test given in Para. 3.
