 A. Test
 Do the EIS input test (Ref. AMM TASK 31-60-00-740-002).

 4. Fault Isolation
_______________
 A. If the test gives the maintenance message DMC3 : ENG2 FF 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 DMC3 : ENG2 FF 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).
 1 If there is no continuity:
_ - repair the wiring.

 2 If there is continuity:
_

 - do a check of the wiring from the DMC1 (1WT1) pins AB/11B, 11C to the first terminal block (Ref. ASM 31-61/04).
 a If there is no continuity:
_ - repair the wiring.

 b If there is continuity:
_

 - do a check and repair the wiring from the DMC1 (1WT1) pins AB/11D, 11E to the first terminal block (Ref. ASM 31-61/04).
 (2) If this test gives no maintenance message:
 - replace the DU-ECAM, UPPER (4WT1) (Ref. AMM TASK 31-63-22-000-001) and (Ref. AMM TASK 31-63-22-400-001).
 (a) If the fault continues:
 - do a check of the wiring from the upper ECAM DU (4WT1) pins AA/35, 36 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 the upper ECAM DU (4WT1) pins AA/38, 39 to the first terminal block (Ref. ASM 31-61/04).
 B. Do the test given in Para. 3.
