_______________
A. If the fault is identified by the crew observation:
FDR SYS uploading is not possible.
(1) Do a check for of the aircraft wiring between the ROUTING BOX-DATA LOADING (102TD) and DMU/FDIU (FDIMU) (10TV) (Ref. ASM 31-38/01):
- A/25 (102TD) to pin AA/14F (10TV).
(2) Do a check for of the aircraft wiring between the DMU/FDIU (FDIMU) (10TV) and the ROUTING BOX-DATA LOADING (102TD):
(a) pin AA/12J, 12K (10TV) to the pin B/12, 28 (102TD).
(b) pin AB/12C, 12D (10TV) to the pin A/42, 9 (102TD).
