 A. Test Do the operational test of the central warning systems (Ref. AMM TASK 31-50-00-710-001).
 4. Fault Isolation
_______________
 A. If the test gives the maintenance message SDAC1 : NO DATA FROM BCL2: do a check of the battery 2 voltage.
 (1) If the voltage is not correct:

 - replace the BAT-2 (2PB2) (Ref. AMM TASK 24-38-51-000-001) and (Ref. AMM TASK 24-38-51-400-001).

 (2) If the voltage is correct:

 - replace the FUSE-BAT 2 (4PB2).
 (a) If the fault continues:
 - replace the BCL-2 (1PB2) (Ref. AMM TASK 24-38-34-000-001) and (Ref. AMM TASK 24-38-34-400-001).

 (b) If the fault continues:

 - replace the SDAC-1 (1WV1) (Ref. AMM TASK 31-55-34-000-001) and (Ref. AMM TASK 31-55-34-400-001).

 (c) If the fault continues:

 - do a check and repair the wiring from the SDAC1 (1WV1) to the BCL2 (1PB2), pins AE/11C, 11D to pins A/P, R (Ref. ASM 31-54/03).
 B. Do the test given in Para. 3.
