_______________
 A. If the fault symptom is identified by the maintenance message on the face of the ISIS indicator: ADIRU3(1FP3) BUS IR/ISIS(22FN-10FC)
 - do the interface test of the IR (system 3) (Ref. AMM TASK 34-14-00-740-001).
 (1) If the test gives a maintenance message, do the trouble shooting procedure related to the maintenance message.

 (2) If the test is OK:

 - do a check of the wiring of the ADIRU 3 BUS 2 IR from the ISIS indicator (22FN) to the ADIRU 3 (1FP3) (Ref. ASM 34-22/02).
 (a) If there is no continuity:
 - replace the defective wiring.
