2 If there is continuity:
_
- do a check of the wiring from DMC1 (1WT1) pins AB/10B, 10C 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 DMC1 (1WT1) pins AB/10D, 10E to the first terminal block (Ref. ASM 31-61/04).
(2) If this test gives no maintenance message:
- replace the PFD-CAPT (2WT1) (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 CAPT PFD (2WT1) pins AA/21, 22 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 CAPT PFD (2WT1) pins AA/23, 24 to the first terminal block (Ref. ASM 31-61/04).
B. If the EIS DMC selector switch (18WT) on the panel 8VU is at F/O/3 and the test gives the maintenance message DMC3 : ATT DSPLY ERR: - on the panel 500VU, push the F/O PFD/ND XFR pushbutton switch (9WT2)
- do the test given in Para. 3.
(1) If this test gives the maintenance message DMC3 : ATT 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 DMC2 (1WT2): . pins AB/9B, 9C to pins AB/10J, 10H . pins AB/9D, 9E to pins AB/10F, 10G (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 DMC2 (1WT2) pins AB/10B, 10C to the first terminal block (Ref. ASM 31-61/04).
