3. Fault Confirmation
__________________
A. Do the DMU (1TV) fault monitoring test (Ref. AMM TASK 31-36-00-710-001). NOTE : Make sure that the circuit breakers 1TV, 5CC2, 14CC2 on the panel
____ 121VU and 5CC1, 14CC1 on the panel 49VU are closed during the test. _______________

A. If the test gives the maintenance message:
- NO BSCU 1 DATA, or
- NO BSCU 2 DATA
(1) Do the operational test of the Normal Braking System (Ref. AMM TASK 32-42-00-710-001).
(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 repair the wiring from the BSCU (10GG) to the DMU (1TV) (Ref. ASM 31-37/01).
