(1) Do the EIS start procedure (Ref. AMM TASK 31-60-00-860-001).
4. Fault Isolation
_______________
A. Make sure that:
- the INVALID DATA message is shown on the CAPT PFD DU and on the CAPT ND DU
- the ECAM warning EIS DMC 1 FAULT is shown on the upper ECAM display
(1) Replace the DMC-1 (1WT1) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
(2) If the fault continues:
- Make sure that there is 115VAC on the pin AC-2 of the DMC1(1WT1)
(a) If there is no 115VAC:
- check and repair the wiring from the DMC1(1WT1) pin AC-2 to the EIS DMC1 SPLY (10WT1)- circuit breaker
1 if there is continuity:
_ - replace the EIS/DMC1/SPLY (10WT1) (Ref. ASM 31-62/01)

- Make sure that there is a ground signal at pin AC-7 of the DMC1(1WT1)
1 if there is no ground signal:
_
- repair the wiring from the DMC1 (1WT1) pin AC-7 to the ground terminal (Ref. ASM 31-62/01).
B. Do the EIS stop procedure (Ref. AMM TASK 31-60-00-860-002).
