B. 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 : ACCELEROMETER 6TU:
- 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:
- do a check of the wiring from the SDAC 1 (1WV1) pins AE/11E, 11F to the first terminal block
(a) If there is no continuity:
- repair the wiring
