- disconnect the electrical connector from the DEU CONNECTION BOX (308RH1) (Ref. ASM 23-73/06).
- do a check of the wiring (continuity-check) between: DIR-CIDS (101RH) connector AA/D14 and the DEU CONNECTION BOX (308RH1) connector pin A/2, DIR-CIDS (101RH) connector AA/E14 and the DEU CONNECTION BOX (308RH1) connector pin A/1.
1 If there is no continuity:
_
- repair the wiring between the DIR-CIDS (101RH) and the connector DEU CONNECTION BOX (308RH1) (Ref. ASM 23-73/06).
2 If there is continuity:
_
- do a check of the wiring (continuity-check) between: DEU CONNECTION BOX (308RH1) pin A/1 and pin A/9 , DEU CONNECTION BOX (308RH1) pin A/2 and pin A/10.

Aug 01/05 CES b If there is continuity:
a_ If there is no continuity:
- install a new DEU CONNECTION BOX (308RH1) (Ref. AMM TASK
23-73-42-000-001) and (Ref. AMM TASK 23-73-42-400-001).
_
- reconnect the connector to the DEU CONNECTION BOX (308RH1).
- do the steps 4. B. (6) again for the subsequent DEU CONNECTION/ TERMINATION BOX(es) until the maintenance message stops: DIR-CIDS (101RH) and DEU CONNECTION BOX (308RH3), DIR-CIDS (101RH) and DEU CONNECTION BOX (308RH5), DIR-CIDS (101RH) and DEU TERMINATION BOX (309RH1).
(7) If the resistance (line to line) is less than 80 ohms (short circuit):
- remove the DECODER/ENCODER UNIT B (300RH7) (Ref. AMM TASK 23-73-47-000-001).
- do a check for a short circuit again.
(a) If there is no short circuit:
- install a new DECODER/ENCODER UNIT B (300RH7) (Ref. AMM TASK 23-73-47-400-001).
(b) If there is a short circuit:
- install the removed DECODER/ENCODER UNIT B (300RH7) (Ref. AMM TASK 23-73-47-400-001).
- diconnect the electrical connector from the DEU TERMINATION BOX (309RH1) (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 (309RH1),
- do the steps 4. B. (7) again for the subsequent DEU(s) and DEU CONNECTION/ TERMINATION BOX(es) until the maintenance message stops for: (Ref. ASM 23-73/06) DEU CONNECTION BOX (308RH3), DEU CONNECTION BOX (308RH5), DEU-B (300RH1) and DEU CONNECTION BOX (308RH1),
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:
_
- repaire the wiring between the related DEU CONNECTION BOX 308RHxx and the DEU CONNECTION/ TERMINATION BOX(es) 308RHxx/309RHxx (Ref. ASM 23-73/06).
b If there is no short circuit:
_
- install a new DEU TERMINATION BOX (309RH1) (Ref. AMM TASK 23-73-48-400-001).
