A. Test Do the operational test of the central warning systems (SDAC) (Ref. AMM TASK 31-50-00-710-001).
4. Fault Isolation
_______________
A. If the test gives the maintenance message SDAC1 : NO DATA FROM BSCU2:
- replace the SDAC-1 (1WV1), (Ref. AMM TASK 31-55-34-000-001) and (Ref. AMM TASK 31-55-34-400-001).
(1) If the fault continues:
- replace the BSCU (10GG), (Ref. AMM TASK 32-42-34-000-001) AND (Ref. AMM TASK 32-42-34-400-001)
(2) If the fault continues:
- do a check and repair the wiring from the SDAC 1 (1WV1) pins AE/14C, 14D to the BSCU (10GG) pins AA/7E, 7F (Ref. ASM 31-54/03)
B. Do the test given in Para. 3.
