B. If the BITE test gives the maintenance message: IR2 or BUS3 to ELAC1 and on the upper ECAM DU, the INOP SYS CAT 3 DUAL warning comes into view:
- replace the ADIRU-2 (1FP2) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
(1) If the fault continues:
(a) Remove the ADIRU2.
(b) Do a check of the wiring of the INERTIAL REFERENCE OUTPUT BUS 3 from the ADIRU2 (1FP2) to the first terminal block.
1 If there is no continuity:
_
a Repair it.
_
b Install the ADIRU2.
_
2 If there is continuity:
_
a Install the ADIRU2.
_ b Do the trouble shooting procedure that follows (Ref. TASK
_
31-32-00-810-934).
C. Do the test given in Para. 3.
