_______________
A. If the test gives a different maintenance message, do the trouble
shooting procedure related to the maintenance message.
B. If there is no maintenance message, but there is a fault in the AIP:
- replace the related AIP (320RHxx) (Ref. AMM TASK 23-73-22-000-001) and (Ref. AMM TASK 23-73-22-400-001).
(1) If the fault continues:
- replace the releted 300RHxx (Ref. AMM TASK 23-73-47-000-001) and (Ref. AMM TASK 23-73-47-400-001) (Ref. ASM 23-73/06).
(a) If the fault continues:
- do a check of the wiring between: the related DEU-B (300RHxx) connector C/15 and the AIP (320RHxx) connector A/4, the related DEU-B (300RHxx) connector C/16 and the AIP (320RHxx) connector A/5, (Ref. ASM 23-73/06).
