R 3. Fault Confirmation
__________________
R A. Test
Removal of the ADIRU (1FP1, 1FP2, 1FP3)
Installation of the ADIRU (1FP1, 1FP2, 1FP3)
BITE Test of the Weather Radar
Removal of the Weather Radar Transceiver (1SQ1, 1SQ2)
Installation of the Weather Radar Transceiver (1SQ1,
1SQ2)
R NOTE : Do the test that follows with the ATT HDG selector switch (13FP),
____ R on the SWITCHING panel 8VU, at NORM then at F/O ON 3.
R Do the BITE test of the weather radar (Ref. AMM TASK 34-41-00-740-002).
R 4. Fault Isolation
_______________
R A. If the test gives the maintenance message ADIRU2+3(1FP2+3) ADR
R BUS/WXR2(1SQ2):
R - replace the XCVR-WEATHER RADAR, 2 (1SQ2) (Ref. AMM TASK 34-41-33-000-R 004) and (Ref. AMM TASK 34-41-33-400-003).
R (1) If the fault continues:
R - swap the ADIRU-2 (1FP2) and the ADIRU1 (Ref. AMM TASK 34-12-34-000-R 001) and (Ref. AMM TASK 34-12-34-400-001).
R (a) If the fault stops:
R - replace the ADIRU that you installed on side 1.

R (b) If the fault continues:
R - swap back the ADIRU1 and the ADIRU2
R - swap the ADIRU-3 (1FP3) and the ADIRU1 (Ref. AMM TASK 34-12-34-
R 000-001) and (Ref. AMM TASK 34-12-34-400-001).
R 1_ If the fault stops:
R - replace the ADIRU that you installed on side 1.
R 2_ If the fault continues:
R - remove the weather radar transceiver 2
R - remove the ADIRU2 and the ADIRU3
R - do a check and repair the wiring from the ADIRU2 to the
R weather radar transceiver 2: from pins AB/5E, 6E of the
R ADIRU2 to pins AB/11J, 12J of the weather radar transceiver
R 2 (Ref. ASM 34-41/01) and the wiring from the ADIRU3 to the
R weather radar transceiver 2: from pins AB/5E, 6E of the
R ADIRU3 to pins AB/12G, 13G of the weather radar transceiver
R 2.
R - install the weather radar transceiver 2
R - install the ADIRU2 and the ADIRU3.
R B. Do the test given in Para. 3.
