 3. Fault Confirmation
__________________
 A. Do the FDIMU (10TV) fault monitoring test (AIDS-part) (Ref. AMM TASK 31-36-00-740-012).
 NOTE : Make sure that the circuit breakers 5TV, 6WV, 7WV, 8WV, 9WV on the
____ panel 121VU and 2WV, 3WV, 5WV, 10WV, 12WV on the panel 49VU are closed during the test.
 4. Fault Isolation
_______________
 A. If the test gives the maintenance message:
 - SDAC1 (1WV1) / FDIMU (10TV) or

 - SDAC2 (1WV2) / FDIMU (10TV)

 (1) Do the ground scanning of the central warning system (Ref. AMM TASK 31-50-00-710-001).

 (a) If the test gives a different maintenance message, you can find the related trouble shooting procedure in the applicable Page Block 101.

 (2) If the fault continues:

 - do a check and if necessary repair the wiring between the SDAC-1 (1WV1) or SDAC-2 (1WV2) and the DMU/FDIU (FDIMU) (10TV) (Ref. ASM 31-37/01):
