_______________
 A. If the test gives the maintenance message DMC1/2/3 (1WT1/2/3)/DDRMI
 (1FN)/ADF1 (2RP1) with the EIS DMC selector switch at NORM only:

 - replace the DMC-1 (1WT1) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
 (1) If the fault continues:
 - remove the DMC1

 - do a check and repair the wiring between the DMC1 and the first terminal block: for pins AA/8C, 8D of the DMC1 (Ref. ASM 34-53/01)

 - install the DMC1.
