- repair the wiring.
(b) If there is continuity:
- do a check and repair the wiring from upper ECAM DU (4WT1) pins AA/38, 39 to DMC1 (1WT1) pins AB/10D, 10E (Ref. ASM 31-61/04).
1 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).
D. Do the test given in Para. 3.

_______________
A. If the test gives the maintenance message DMC1 : DU ECAM1 LINK:
- on the ECAM control panel, set the UPPER DISPLAY potentiometer to OFF and do the test given in Para. 3.
(1) If this test gives the maintenance message DMC1 : DU ECAM1 LINK:
- replace the DMC-1 (1WT1) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
(a) If the fault continues:
- do a check of the wiring from DMC1 (1WT1) pins AB/11B, 11C to the first terminal block (Ref. ASM 31-61/04).
1 If there is no continuity:
_ - repair the wiring.
2 If there is continuity:
_
- do a check and repair the wiring from DMC1 (1WT1) pins AB/11D, 11E to the first terminal block (Ref. ASM 31-61/04).
