_______________
A. If the test gives the maintenance message SDAC1: NO CPCU1 DATA 11HL or SDAC1: NO CPC 1 ANALOG SIGNAL:
- do the operational test of the pressure control and monitoring system (Ref. AMM TASK 21-31-00-710-002).
(1) If the test gives a different maintenance message refer to the Fault Symptom List.
(2) If the test is OK: replace the SDAC-1 (1WV1) (Ref. AMM TASK 31-55-34-000-001) and (Ref. AMM TASK 31-55-34-400-001).
