 A. Do the loading of the correct data base of the TCAS (Ref. AMM TASK 34-43-00-610-001).
 4. Fault Isolation
_______________
 A. If the fault is identified by the crew observation:
 TCAS uploading is not possible.

 (1) Do a check for of the aircraft wiring between the ROUTING BOX-DATA LOADING (102TD) and CMPTR-TCAS (1SG) (Ref. ASM 31-38/01):

 (a) pin B/48, 15 (102TD) to pin AE/9A, 9B (1SG).

 (b) pin A/47, 14 (102TD) to pin AE/8A, 8B (1SG).

 (c) pin A/30 (102TD) to pin AE/6A (1SG).

 (2) 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).
