PRESSURE CONTROL AND MONITORING - TASK SUPPORTING DATA

** ON A/C NOT FOR ALL

1. Cabin Pressure Controller

Pressure Control and Monitoring - Block Diagram

A. CFDS Fault Information
Additional information about a failed component are available in the MCDU CAB PRESS CONT menu.
The related LAST LEG REPORT page shows:

the date and time when the fault occurs,
the ATA number of the component,
the FIN of the component,
a fault code for shop maintenance.

B. Additional BITE Fault Information Handling
If a fault is detected by the CPC BITE, a fault code for shop maintenance is shown on the CFDS in addition to the related CFDS message.
The subsequent tables show the possible fault codes with their attached fault origins:

NOTE: There are five tables in this sub-paragraph.
This table is only applicable to Cabin Pressure Controller Part Numbers 9022-15702-9 and previous.
