_______________
 A. If the test gives the maintenance message DMC2 : ENG1 N2 DSPLY ERR:
 - on the ECAM control panel (6WT), set the UPPER DISPLAY potentiometer to OFF
 - do the test given in Para. 3.
 (1) If this test gives the maintenance message DMC2 : ENG1 N2 DSPLY ERR:
 - replace the DMC-2 (1WT2) (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 DMC2 (1WT2) pins AB/11B, 11C to the first terminal block (Ref. ASM 31-61/04).
 1 If there is no continuity:
_ - repair the wiring.
