_______________
A. If the test gives the maintenance message DMC2 - DU ECAM2 LINK:
- replace the DU-ECAM, LOWER (4WT2) (Ref. AMM TASK 31-63-22-000-001) and (Ref. AMM TASK 31-63-22-400-001).
(1) If the fault continues:
- do a check of the wiring from the lower ECAM DU (4WT2) to the DMC2 (1WT2): . pins AA/35, 36 to pins AB/11B, 11C . pins AA/38, 39 to pins AB/11D, 11E (Ref. ASM 31-61/04).
(a) If there is no continuity:
- repair the wiring.
(b) If there is continuity:
- replace the DMC-2 (1WT2) (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.

_______________
A. If the test gives the maintenance message DMC3 : ENG1 N1 DSPLY ERR:
- 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 DMC3 : ENG1 N1 DSPLY ERR:
- replace the DMC-3 (1WT3) (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 the DMC3 (1WT3) to the DMC1 (1WT1): . pins AB/11B, 11C to pins AB/11J, 11H . pins AB/11D, 11E to pins AB/11F, 11G (Ref. ASM 31-61/04).
