A. CFDIU Interface
(1) BITE description The BITE facilitates maintenance on in-service aircraft. It detects and identifies a failure related to the MMR. The BITE of the MMR is connected to the CFDIU. The BITE:
-transmits permanently MMR status and its identification message to the CFDIU
-memorizes the failures which occurred during the last 63 flight legs
-monitors data inputs from the various peripherals
-transmits to the CFDIU the result of the tests performed and self-tests
-can communicate with the CFDIU through the menus. The BITE can operate in two modes:
-
the normal mode
-
the menu mode.
(a)
Normal mode During the normal mode, the BITE cyclically monitors the status of the MMR. It transmits its information to the CFDIU during the concerned flight. In case of fault detection, the BITE stores the information in the fault memories. These items of information are transmitted to the CFDIU by an ARINC 429 message with label 356.
(b)
Menu mode The menu mode can only be activated on ground. This mode enables communication between the CFDIU and the MMR BITE by means of the MCDU. (Ref. Fig. 016) When you get access to the SYSTEM REPORT/TEST/NAV page, the ILS1 and ILS2 indications can be shown instead of the MMR1 and MMR2 indications. In this case, you must do the following steps:
-
make sure that the the engines are shut down - open CFDIU SUPPLY circuit breaker 2TW - open CFDIU BACK UP circuit breaker 8TW
-
make sure that MMR1 and MMR2 circuit breakers, 42RT1 and 42RT2, are closed
-wait for 30 seconds then close the CFDIU circuit breakers 2TW and 8TW

REPORT/TEST/NAV page. All the information displayed on the MCDU during the BITE Test configuration can be printed by the printer (Ref. 31-35-00). The MMR menu mode is composed of:
-LAST LEG REPORT (Ref. Fig. 017A) This menu contains the fault messages (class 1 internal and external) detected during the last flight.
-PREVIOUS LEGS REPORT (Ref. Fig. 018A) This report contains the fault messages related to the external or internal failures (class 1) recorded during the previous 63 flight legs.
