2_ If there is continuity:
- do a check and repair the wiring from DMC2 (1WT2) pins
AB/9D, 9E to the first terminal block (Ref. ASM 31-61/04).
(2) If this test gives no maintenance message:
- replace the PFD-F/O (2WT2) (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 F/O PFD (2WT2) 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:
