R **ON A/C 001-049, 051-099, 101-149, 151-199, 201-299, 301-399,
A. If the test gives the maintenance message:
DMC1 : NO SDAC2 DATA
- 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:
- do a check and repair the wiring from the DMC 1 (1WT1) pins AA/10G, 10H to the first terminal block , (Ref. ASM 31-54/04).
R **ON A/C 401-499,
A. If the test gives the maintenance message:
SDAC2(1WV2)/DMC1(1WT1)
- 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:
- do a check and repair the wiring from the DMC 1 (1WT1) pins AD/6C, 6D to the first terminal block , (Ref. ASM 31-54/04).
