**ON A/C 001-049, 051-099, 101-105, 201-299,
B. If the CIDS1/CIDS BUS test gives the maintenance message TOP LINE 1R:
- 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)
- open these CBs: 49VU: 154RH COM/CIDS/DEU A ESS/LINE 1 49VU: 155RH COM/CIDS/DEU A ESS/LINE 2 121VU: 164RH COM NAV/CIDS/DEU A NORM/R FWD 121VU: 166RH COM NAV/CIDS/DEU A NORM/R MID 121VU: 168RH COM NAV/CIDS/DEU A NORM/R AFT
- make sure that the resistance (line to line) at DIR-CIDS (101RH) and (102RH) connector AA/A15 and connector AA/B15 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/A15 and GND, DIR-CIDS (101RH) and (102RH) connector AA/B15 and GND. (Ref. ASM 23-73/06)
(a) If there is no short circuit:
- remove the DEU-A (200RH24) (Ref. AMM TASK 23-73-46-000-001)
- install the DIR-CIDS (101RH) and DIR-CIDS (102RH) (Ref. AMM TASK 23-73-34-400-001).
- close these CBs: 49VU: 154RH COM/CIDS/DEU A ESS/LINE 1 49VU: 155RH COM/CIDS/DEU A ESS/LINE 2 121VU: 164RH COM NAV/CIDS/DEU A NORM/R FWD 121VU: 166RH COM NAV/CIDS/DEU A NORM/R MID 121VU: 168RH COM NAV/CIDS/DEU A NORM/R AFT 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 COMMUNICATIONS 通讯2(83)
