_______________
 A. If the test gives the maintenance message NO IR1 DATA:
 - replace the ADIRU-1 (1FP1) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
 (1) If the fault continues:
 - do a check and repair the wiring of the INERTIAL REFERENCE OUTPUT BUS 3 bus from the ADIRU 1 (1FP1) to the first terminal block (Ref. ASM 34-14/01).
 B. Do the test given in Para. 3.
