201-299, Aug 01/05 CES 3. Fault Confirmation
__________________
A. Test
(1) Do the CIDS1/CIDS BUS test through the MCDU/CFDS.
(2) Do the CIDS1/DEU-A test through the MCDU/CFDS.
4. Fault Isolation
_______________
A. If the test gives a different maintenance message, do the trouble shooting procedure related to the maintenance message.
**ON A/C 001-049, 051-099, 101-105, 201-299,
B. If the CIDS1/CIDS BUS test gives the maintenance message TOP LINE 2R:
- remove the DIR-CIDS (101RH) (Ref. AMM TASK 23-73-34-000-001),
- make sure that at least one cabin door is open,
- close these CBs:
49VU: 150RH (G02) CIDS/DIR 1 & 2/ESS,
121VU:151RH (M05) CIDS/DIR 1 & 2/NORM,
- wait for approx. 120 s,
- do the CIDS2/CIDS BUS test through the MCDU/CFDS.
(1) If the CIDS2/CIDS BUS test is OK:
- install a new DIR-CIDS, 1 (101RH) (Ref. AMM TASK 23-73-34-400-001).
(2) If the fault continues:
- remove the DIR-CIDS, 2 (102RH) (Ref. AMM TASK 23-73-34-000-001).
- install the DIR-CIDS, 1 (101RH) (Ref. AMM TASK 23-73-34-400-001).
- do the CIDS1/CIDS BUS test through the MCDU/CFDS.
(3) If the CIDS1/CIDS BUS test is OK:
- install a new DIR-CIDS, 2 (102RH) (Ref. AMM TASK 23-73-34-400-001).
(4) If the fault continues:
- remove the DIR-CIDS, 1 (101RH) (Ref. AMM TASK 23-73-34-000-001)
- make sure that the resistance (line to line) at DIR-CIDS (101RH) and (102RH) connector AA/F15 and connector AA/G15 is between approx. 80 and 200 ohms (Ref. ASM 23-73/06).
(5) If the resistance (line to line) is between approx. 80 and 200 ohms:
- make sure that the resistance (line to GND) is not less than 50 ohms (short circuit) between: DIR-CIDS (101RH) and (102RH) connector AA/F15 and GND, DIR-CIDS (101RH) and (102RH) connector AA/G15 and GND. (Ref. ASM 23-73/06)
