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 SDAC2 : NO DATA FROM EGIU1-2:
- replace the SDAC-2 (1WV2), (Ref. AMM TASK 31-55-34-000-001) and (Ref. AMM TASK 31-55-34-400-001).
(1) If the fault continues:
- replace the EGIU-1 (22XU1), (Ref. AMM TASK 24-22-33-000-001) and (Ref. AMM TASK 24-22-33-400-002).
(a) If the fault continues:
- do a check and repair the wiring from the SDAC 2 (1WV2) to the EGIU 1 (22XU1) from pins AE/10A, 10B to pins AB/13C, 13D (Ref. ASM 31-54/03).
B. Do the test given in Para. 3.
