(2) If the coding switch position(s) is (are) correct:

 - replace the DEU-A (200RHxx) (Ref. AMM TASK 23-73-46-000-001) and (Ref. AMM TASK 23-73-46-400-001).
 (a) If the fault continues:
 - replace the related Connection Box 208RHxx (Ref. AMM TASK 23-73-42-000-001) and (Ref. AMM TASK 23-73-42-400-001) or Termination Box 209RHxx (Ref. AMM TASK 23-73-43-000-001) or (Ref. AMM TASK 23-73-43-400-001).
 1 If the fault continues:
_
 - do a check for 28VDC at the related Connection Box 208RHxx or Termination Box 209RHxx connector A/8, connector A/5 and connector A/8, and GND signal at connector A/7, (Ref. ASM 23-73/06), (Ref. ASM 23-73/07) and (Ref. ASM 23-73/08) and repair the wiring if necessary.
 **ON A/C 151-199,
 B. If the CIDS1/DEU-A test gives the maintenance message DEU-A 200RHxx:
 - make sure that at least one cabin door is open,

 - open these CBs:
 49VU: 150RH (G01) COM DIR ESS/1
 49VU: 157RH (G02) COM DIR ESS/2
 121VU:151RH (M06) CIDS/DIR NORM/1,
 121VU:156RH (M07) CIDS/DIR NORM/2,

 - wait for approx. 10 s and close the CBs 156RH and 157RH,

 - stop for approx. 120 s,

 - do the CIDS/DEU-A test (via CIDS2).

 (1) If the CIDS2/DEU-A test is OK:
 - install a new DIR-CIDS, 1 (101RH) (Ref. AMM TASK 23-73-34-400-001)

 - make an adjustment of the related coding switch(es).

 (b) If the coding switch position(s) is (are) correct:

 - replace the DEU-A (200RHxx) (Ref. AMM TASK 23-73-46-000-001) and (Ref. AMM TASK 23-73-46-400-001).
 1_ If the fault continues:
 - replace the DEU mount 2010VUxx (Ref. AMM TASK 23-73-48-000-
001) and (Ref. AMM TASK 23-73-48-400-001).

 a If the fault continues:
_
 - do a check for 28VDC at DEU mount 2010VUxx connector A/8, 28VDC at DEU mount 2010VUxx connector A/5, GND at DEU mount 2010VUxx connector A/7, (Ref. ASM 23-73/06), (Ref. ASM 23-73/07) and (Ref. ASM 23-73/08) and repair the wiring if necessary.
