 4. Fault Isolation
_______________

 A. If the operational test gives the maintenance message RDG LIGHT XX L, R (XX seat row) and the related lamp does not come on:
 - replace the LAMP (Ref. AMM TASK 23-73-64-000-001) and (Ref. AMM TASK 23-73-64-400-001).
 (1) If the fault continues:
 - replace the related FUSE (Ref. AMM TASK 23-73-38-960-002).
 (a) If the fault continues:
 - replace the related READING LIGHT POWER UNIT (Ref. AMM TASK 23-73-38-000-001) and (Ref. AMM TASK 23-73-38-400-001).
 1_ If the fault continues:
 - replace the related PCB 2038VUA (Ref. AMM TASK 23-73-49-000-
001) and (Ref. AMM TASK 23-73-49-400-001).

 B. If the operational gives the maintenance message RDG LIGHT XX L, R and the lamp comes on:
 - replace the related DEU-A (Ref. AMM TASK 23-73-46-000-001) and (Ref. AMM TASK 23-73-46-400-001).
 (1) If the fault continues:
 - do a check and repair the wiring between the related: READING-LIGHT POWER UNIT conn. A/H and DEU-A conn. C/35 (Page 101) READING-LIGHT POWER UNIT conn. A/H and DEU-A conn. C/42 (Page 102) READING-LIGHT POWER UNIT conn. A/H and DEU-A conn. C/28 (Page 103) READING-LIGHT POWER UNIT conn. A/B and GND (Ref. ASM 23-73/13) and (Ref. ASM 33-25/01).
 C. Do the test as given in the Para. 3.A.
 5. Close-up
________
 A. Put the aircraft back to its initial configuration.
