A. If the test gives the maintenance message DMC 2 : NO ADC 2 DATA:
- replace the DMC-2 (1WT2) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
(1) If the fault continues:
- replace the ADIRU-2 (1FP2) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
(2) If the fault continues:
- do a check and repair the wiring from the ADIRU 2 (1FP2) to the DMC 2 (1WT2) (Ref. ASM 31-62/01).

- replace the DMC-2 (1WT2) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
(1) If the fault continues:
- do a check and repair the wiring from ADIRU2(1FP2) pins AA-3A/3B to DMC2(1WT2) pins AA-5G/5H (Ref. ASM 31-62/01).
(2) If the fault continues:
- replace the ADIRU-2 (1FP2) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
