4. Fault Isolation
_______________
A. If the test gives a different maintenance message, do the trouble shooting procedure related to the maintenance message.
**ON A/C 001-049, 051-099, 101-105, 201-299,
B. If the CIDS1/DEU-A test gives the maintenance message DEU-A 200RHxx:
- remove the 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,
- 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)
(2) If the fault continues:
- make sure that the related coding switch(es) is (are) set to the correct DEU-A address (Ref. ASM 23-73/06), (Ref. ASM 23-73/07) and (Ref. ASM 23-73/08).
(a) If the coding switch position(s) is (are) not correct:
- 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,
