R **ON A/C 001-049, 051-099, 101-105, 151-199, 201-210,
A. If the fault identified by the crew observation:
MCDU 1 and MCDU 2 shows AIDS (TIME OUT)
(1) Do the DMU (1TV) Fault Monitoring Test (Ref. AMM TASK 31-36-00-710-001).
R (a) If the test gives a different maintenance message, do the trouble R shooting procedure related to the maintenance message.

(2) If the fault continues:
- do a check and repair the aircraft wiring from the MCDU 1 (3CA1), MCDU 2 (3CA2), CFDIU (1TW) and Printer (4TW) to the DMU (1TV) (Ref. ASM 31-36/01): MCDU 1 Connector 11 to DMU Connector AA/11E MCDU 1 Connector 12 to DMU Connector AA/11F MCDU 2 Connector 11 to DMU Connector AA/11E MCDU 2 Connector 12 to DMU Connector AA/11F CFDIU Connector AB/3F to DMU Connector AA/11E CFDIU Connector AB/3G to DMU Connector AA/11F Printer Connector C to DMU Connector AA/11E Printer Connector D to DMU Connector AA/11F
(3) If the fault continues:
- replace the DMU (1TV) (Ref. AMM TASK 31-36-34-000-001) and (Ref. AMM TASK 31-36-34-400-001).
(4) If the fault continues:
- do the fault isolation procedure (Ref. TASK 31-32-00-810-934) of the MCDU 1 (3CA1), MCDU 2 (3CA2), CFDIU (1TW) and Printer (4TW).
B. Do the DMU (1TV) Fault Monitoring Test (Ref. AMM TASK 31-36-00-710-001) to check the correct operation (no maintenance message is shown).

A. If the fault identified by the crew observation:
MCDU 1 and MCDU 2 shows AIDS (TIME OUT)
(1) Do the FDIMU (10TV) Fault Monitoring Test (Ref. AMM TASK 31-36-00-740-012).
(a) If the test gives a different maintenance message, do the trouble shooting procedure related to the maintenance message.
(2) If the fault continues:
- do a check and repair the aircraft wiring from the MCDU 1 (3CA1), MCDU 2 (3CA2), CFDIU (1TW) and Printer (4TW) to the FDIMU (10TV) (Ref. ASM 31-36/01):

(3) If the fault continues:
- replace the DMU/FDIU (FDIMU) (10TV) (Ref. AMM TASK 31-36-34-000-002) and (Ref. AMM TASK 31-36-34-400-002).
(4) If the fault continues:
- do the fault isolation procedure (Ref. TASK 31-32-00-810-934) of the MCDU 1 (3CA1), MCDU 2 (3CA2), CFDIU (1TW) and Printer (4TW).
B. Do the FDIMU (10TV) Fault Monitoring Test (Ref. AMM TASK 31-36-00-740-012) to check the correct operation (no maintenance message is shown).
