A. If the test gives the maintenance message:
DMC2 : NO SDAC1 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:
- do a check and repair the wiring from the DMC 2 (1WT2) pins AA/10C, 10D to the first terminal block , (Ref. ASM 31-54/04).
R **ON A/C 401-499,
A. If the test gives the maintenance message:
SDAC1(1WV1)/DMC2(1WT2)
- 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 the DMC 2 (1WT2) pins AD/6G, 6H to the first terminal block , (Ref. ASM 31-54/04).
