A. If it is not possible to print the FMGC2 data on the printer (4TW):
- replace the PRINTER (4TW) (Ref. AMM TASK 31-35-22-000-001) and (Ref. AMM TASK 31-35-22-400-001).
(1) If the fault continues:
- replace the FMGC-2 (1CA2) (Ref. AMM TASK 22-83-34-000-001) and (Ref. AMM TASK 22-83-34-400-001).
(a) If the fault continues:
- do a check of the wiring from FMGC2 (1CA2) pins AB/12F, 12G to printer (4TW) pins A/A, B (Ref. ASM 31-35/01).
1 If there is no continuity:
_ - repair the wiring.
2 If there is continuity:
_
- do a check of the wiring from MCDU1 (3CA1) pins A/27, 28 to FMGC2 (1CA2) pins AA/9F, 9G (Ref. ASM 22-86/04).
a If there is no continuity:
_ - repair the wiring.
b If there is continuity:
_
- replace the MCDU-1 (3CA1) (Ref. AMM TASK 22-82-12-000-001) and (Ref. AMM TASK 22-82-12-400-002).
