A. Not applicable, the fault is evident.
4. Fault Isolation
_______________
A. If the fault is identified by the crew observation: UP-LOADING ERROR indication on the display of the Data Loading Selector
(1) if the fault continues:
- replace the ROUTING BOX-DATA LOADING (102TD) (Ref. AMM TASK 31-38-34-000-001) and (Ref. AMM TASK 31-38-34-400-001).
(2) if the fault continues:
- replace the SELECTOR-DATA LOADING (101TD) (Ref. AMM TASK 31-38-21-000-001) and (Ref. AMM TASK 31-38-21-400-001).
(3) Do a check for of the aircraft wiring between the ROUTING BOX-DATA LOADING (102TD) and MDDU (1TD) (Ref. ASM 31-38/01):
(a) pin B/19, 35 (102TD) to pin A/1, 2 (1TD).
(b) pin B/18, 34 (102TD) to pin A/8, 9 (1TD).
