A. If the test gives the maintenance message DMC 3 : NO ILS 1 DATA:
- replace the DMC-3 (1WT3) (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 3 (1WT3) pins AA/6A, 6B to the first terminal block (Ref. ASM 31-62/01).
R **ON A/C 401-499,
A. If the test gives the maintenance message ILS1(40RT1)/DMC3(1FP3) or MMR1(40RT1)/DMC3(1WT3)
- replace the DMC-3 (1WT3) (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 ILS1/MMR1(40RT1) pins AB-1G/1H to the DMC3(1WT3) pins AA-10A/10B (Ref. ASM 31-62/01).
(2) If the fault continues:
- replace the ILS1(40RT1) (Ref. AMM TASK 34-36-31-000-003) and (Ref. AMM TASK 34-36-31-400-003), or the MMR1(40RT1) (Ref. AMM TASK 34-36-31-000-002) and (Ref. AMM TASK 34-36-31-400-002).
