A. If the test gives the maintenance message WRG:VMO-MMO DISCRETE:
- remove the ADIRU1 (Ref. AMM TASK 34-12-34-000-001)
- do a check and repair the wiring of the ADIRU1 VMO/MMO discrete input from the ADIRU1 to the L/G down VMO/MMO selection switch (22FP)
- install the ADIRU1 (Ref. ASM 34-13/02) and (Ref. AMM TASK 34-12-34-400-001).
(1) If the fault continues:
- replace the ADIRU-1 (1FP1) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
