A. If the test gives the maintenance message DMC1 : ATT DSPLY ERR:
- on the panel 301VU, push the CAPT PFD/ND XFR pushbutton switch (9WT1) to get the PFD image on the CAPT ND
- do the test given in Para. 3.
(1) If this test gives the maintenance message DMC1 : ATT DSPLY ERR:
- 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/9B, 9C to the first terminal block (Ref. ASM 31-61/04).
1 If there is no continuity:
_ - repair the wiring.
