(19FP1,19FP2,19FP3,19FP4,19FP5,19FP6, 19FP7,19FP8) AMM 34-12-34-000-001 Removal of the ADIRU (1FP1, 1FP2, 1FP3) AMM 34-12-34-400-001 Installation of the ADIRU (1FP1, 1FP2, 1FP3) AMM 34-14-00-740-001 Interface Test of the IR ASM 34-13/03
3. Fault Confirmation
__________________
A. Do the interface test of the IR (system 3) (Ref. AMM TASK 34-14-00-740-001).
4. Fault Isolation
_______________
A. If the test gives the maintenance message ADIRU3 (1FP3) ADR BUS 1:
- swap the ADIRU-3 (1FP3) and the ADIRU1 (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
(1) If the fault stops:
- replace the ADIRU that you installed on side 1.

401-499, Aug 01/05 CES
(2) If the fault continues:
- get access to the ADM-STBY TOTAL PRESSURE (19FP3) and ADM-STBY STATIC PRESSURE (19FP8) (Ref. AMM TASK 34-11-17-000-001) (Para. 2.A.)
- disconnect the electrical connector of the STBY total pressure ADM (19FP3) and make sure that there is +13.5V between pins A/C, A and -13.5V between pins A/C, E of the connector receptacle (Ref. ASM 34-13/03).
(a) If the voltages are not OK:
- do a check and repair the wiring between the ADIRU3 and the connector receptacle of the STBY total pressure ADM (19FP3): for pins AA/6G, 6H and 6J of the ADIRU3 and pins A/A, C and E of the connector receptacle
- connect the electrical connector of the STBY total pressure ADM (19FP3).
(b) If the voltages are OK:
- disconnect the electrical connector of the STBY static pressure ADM (19FP8) and make sure that there is +13.5V between pins A/C, A and -13.5V between pins A/C, E of the connector receptacle (Ref. ASM 34-13/03).
1_ If the voltages are not OK:
- do a check and repair the wiring between the connector
receptacle of the STBY static pressure ADM (19FP8) and the
first terminal block: for pins A/A, C and E of the connector
receptacle
- connect the electrical connectors of the STBY total pressure
ADM (19FP3) and the STBY static pressure ADM (19FP8).
2 If the voltages are OK and if the fault continues:
_
- replace the ADM-STBY TOTAL PRESSURE (19FP3) (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001).
a If the fault continues :
_
- replace the ADM-STBY STATIC PRESSURE (19FP8).
B. Do the test given in Para. 3.
