4. Fault Isolation
_______________
A. If it is not possible to print the DMU (or FDIMU) 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 (with DMU installed):
- replace the DMU (1TV) (Ref. AMM TASK 31-36-34-000-001) and (Ref. AMM TASK 31-36-34-400-001).
(a) If the fault continues:
- do a check of the wiring from DMU (1TV) pins AA/11E, 11F to printer (4TW) pins A/C, D (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 DMU (1TV) pins AA/11A, 11B (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).
(2) If the fault continues (with FDIMU installed):
- replace the DMU/FDIU (FDIMU) (10TV) (Ref. AMM TASK 31-36-34-000-002) and (Ref. AMM TASK 31-36-34-400-002).
(a) If the fault continues:
- do a check of the wiring from FDIMU (10TV) pins AA/11E, 11F to printer (4TW) pins A/C, D (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 FDIMU (10TV) pins AA/11A, 11B (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).
B. Do the action given in Para. 3.B.
