A. Test Do the operational test of the DMC/DU Data Bus (Ref. AMM TASK 31-60-00-720-002)
4. Fault Isolation
_______________
A. If the test gives:
(1) the maintenance message DU EWD (4WT1)/WRG: DMC1 (1WT1)
- check the wiring between the DMC1 and the Upper ECAM DU (4WT1) (Ref. ASM 31-61/00)
(a) if the wiring is correct:
- replace the DU-ECAM, UPPER (4WT1) (Ref. AMM TASK 31-63-22-000-001)and (Ref. AMM TASK 31-63-22-400-001)
(b) If the fault continues:
- replace the DMC-1 (1WT1) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001)
B. Do the test given in Para. 3.

3. Fault Confirmation
__________________
A. Test
(1) Make sure that the DMC2 is correctly installed (Ref. AMM TASK 31-63-34-400-001)
(2) Do the operational test of the DMC/DU Data Bus (Ref. AMM TASK 31-60-00-720-002)
4. Fault Isolation
_______________
A. If the test gives:
(1) the maintenance message DU SD (4WT2)/WRG: DMC2 (1WT2)
- do the relative fault isolation procedure (Ref. TASK 31-63-81-810-971)
(2) the maintenance message DU SD (4WT2)/WRG: DMC1 (1WT1)
- check the wiring between the DMC1 and the Lower ECAM DU (4WT2) (Ref. ASM 31-61/00)
(a) if the wiring is correct:
- replace the DU-ECAM, LOWER (4WT2) (Ref. AMM TASK 31-63-22-000-001)and (Ref. AMM TASK 31-63-22-400-001)
(b) If the fault continues:
- replace the DMC-1 (1WT1) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001)
B. Do the test given in Para. 3.
