A. Test
(1) Do a read-out of the CLASS III FAULT REPORT of the cabin
pressure-control system.
NOTE : If a fault is detected, the CLASS III FAULT REPORT of the CPC
____ shows a fault code for shop maintenance in addition to the related CFDS message(s). For detailed information see the applicable Page Block 301.
(2) Make sure that all ADIRS (1,2 and 3) are switched on.
(3) Do the operational test of the pressure control and monitoring system (Ref. AMM TASK 21-31-00-710-002).
