(6) If the resistance (line to line) is more than 120 ohms (open circuit):
- disconnect the electrical connector from the DEU TERMINATION BOX (209RH2),
- make sure that the resistance (line to line) is not more than 120 ohms (open circuit) between: DEU TERMINATION BOX (209RH2) pin A/1 and pin A/2
(a) If there is an open circuit:
- install a new DEU TERMINATION BOX (209RH2) (Ref. AMM TASK 23-73-43-000-001) and (Ref. AMM TASK 23-73-43-400-001).
(b) If there is no open circuit:
- reconnect the electrical connector to the DEU TERMINATION BOX (209RH2),
- disconnect the electrical connector from the DEU CONNECTION BOX (208RH2),
- do a check of the wiring (continuity-check) between: DIR-CIDS (101RH) connector AA/A15 and the connector from the DEU CONNECTION BOX (208RH2) pin A/2, DIR-CIDS (101RH) connector AA/B15 and the connector from the DEU CONNECTION BOX (208RH2) pin A/2.
1 If there is no continuity:
_
- repair the wiring between the DIR-CIDS (101RH) and the connector of the DEU CONNECTION BOX (208RH2) (Ref. ASM 23-73/06).
2 If there is continuity:
_
- do a check of the wiring (continuity-check) between: DEU CONNECTION BOX (208RH2) pin A/1 and pin A/9 , DEU CONNECTION BOX (208RH2) pin A/2 and pin A/10.
a If there is no continuity:
_
- install a new DEU CONNECTION BOX (208RH2) (Ref. AMM TASK 23-73-42-000-001) and (Ref. AMM TASK 23-73-42-400-001).
b If there is continuity:
_
- reconnect the connector DEU CONNECTION BOX (208RH2).
- do the steps 4. B. (6) again for the subsequent DEU CONNECTION BOXES until the maintenance message stops: DIR-CIDS (101RH) and DEU CONNECTION BOX (208RH4), DIR-CIDS (101RH) and DEU CONNECTION BOX (208RH6), DIR-CIDS (101RH) and DEU CONNECTION BOX (208RH8), DIR-CIDS (101RH) and DEU CONNECTION BOX (208RH10), DIR-CIDS (101RH) and DEU CONNECTION BOX (208RH12), DIR-CIDS (101RH) and DEU CONNECTION BOX (208RH14), DIR-CIDS (101RH) and DEU TERMINATION BOX (209RH2),

(7) If the resistance (line to line) is less than 80 ohms (short circuit):
- remove the DEU-A (200RH16) (Ref. AMM TASK 23-73-46-000-001).
- do a check for a short circuit again.
(a) If there is no short circuit:
- install a new DEU-A (200RH16) (Ref. AMM TASK 23-73-46-400-001).
(b) If there is a short circuit:
- install the removed DEU-A (200RH16) (Ref. AMM TASK 23-73-46-400-001).
- disconnect the electrical connector from the DEU TERMINATION BOX (209RH2) (Ref. ASM 23-73/06),
- do a check for a short circuit again.
1 If there is a short circuit:
_
- reconnect the electrical connector to the DEU TERMINATION BOX (209RH2),
- do the steps 4. B. (7) again for the subsequent DEUs and DEU CONNECTION BOXES until the maintenance message stops: (Ref. ASM 23-73/06) DEU-A (200RH14) and DEU CONNECTION BOX (208RH14), DEU-A (200RH12) and DEU CONNECTION BOX (208RH12), DEU-A (200RH10) and DEU CONNECTION BOX (208RH10), DEU-A (200RH8) and DEU CONNECTION BOX (208RH8), DEU-A (200RH6) and DEU CONNECTION BOX (208RH6), DEU-A (200RH4) and DEU CONNECTION BOX (208RH4), DEU-A (200RH2) and DEU CONNECTION BOX (208RH2),
2 If there is no short circuit:
_
- do a check for a short circuit at the disconnected connector between the pins A/9 and A/10 (Ref. ASM 23-73/06)
a If there is a short circuit:
_
- repair the wiring between the related DEU CONNECTION BOX 208RHxx and the DEU CONNECTION/ TERMINATION BOX 208/209RHxx (Ref. ASM 23-73/06).
b If there is no short circuit:
_
- install a new DEU TERMINATION BOX (209RH2) (Ref. AMM TASK 23-73-43-000-001) and (Ref. AMM TASK 23-73-43-400-001).
**ON A/C 001-049, 051-099, 101-105, 151-199, 201-299,
C. Installation of removed components
- Install the removed DIR-CIDS, 1 (101RH) and DIR-CIDS, 2 (102RH) (Ref. AMM TASK 23-73-34-400-001).
- Install all the removed DEU-A (200RHxx) (Ref. AMM TASK 23-73-46-400-001).
