B. If the CIDS BITE test result is no fault message, but an announcement is not possible:
- remove DIR-CIDS, 1 (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,
- stop for approx. 120 s,
- make an announcement again.
(1) If an announcement is possible:
- install a new DIR-CIDS, 1 (101RH) (Ref. AMM TASK 23-73-34-400-001).
(2) If an announcement is not possible:
- replace the cockpit handset.
(a) If the fault continues:
- do a check and repair the wiring between the: DIR-CIDS (101RH) connector AB/J2 and the COCKPIT HANDSET (130RH) connector A/1, DIR-CIDS (101RH) connector AB/K2 and the COCKPIT HANDSET (130RH) connector A/2, DIR-CIDS (101RH) connector AB/C1 and the COCKPIT HANDSET (130RH) connector A/4, DIR-CIDS (101RH) connector AB/D1 and the COCKPIT HANDSET (130RH) connector A/5, DIR-CIDS (101RH) connector AB/G1 and the COCKPIT HANDSET (130RH) connector A/6, DIR-CIDS (101RH) connector AB/H1 and the COCKPIT HANDSET (130RH) connector A/7, DIR-CIDS (101RH) connector screen and GND, COCKPIT HANDSET (130RH) connector 3 and DIR-CIDS (101RH) connector screen (Ref.
