- stop for approx. 120 s,
- do the test again.
(1) If the test is OK:
- install a new DIR-CIDS, 1 (101RH) (Ref. AMM TASK 23-73-34-400-001).
(2) If the fault continues:
- replace all related DEU-A 200RH (Ref. AMM TASK 23-73-46-000-001) and (Ref. AMM TASK 23-73-46-400-001).
(a) If the fault continues:
- do a check and repair the wiring between the related: DEU mount connector A/8 and CB 163RH, DEU mount connector A/8 and CB 164RH, DEU mount connector A/8 and CB 165RH, DEU mount connector A/8 and CB 166RH, DEU mount connector A/8 and CB 167RH, DEU mount connector A/8 and CB 168RH, DEU mount connector A/5 and CB 154RH, DEU mount connector A/5 and CB 155RH, DEU mount connector A/7 and GND (Ref.
