 (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 2) (Ref. AMM TASK 34-14-00-740-001).
 4. Fault Isolation
_______________
 A. If the test gives the maintenance message ADIRU2 (1FP2) ADR BUS 1:
 - swap the ADIRU-2 (1FP2) 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-R TOTAL PRESSURE (19FP2), ADM-R STATIC PRESSURE (19FP6) and ADM-L STATIC PRESSURE (19FP7) (Ref. AMM TASK 34-11-17-000-001) (Para. 2.A.)

 - disconnect the electrical connector of the L total pressure ADM (19FP2) 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 ADIRU2 and the connector receptacle of the R total pressure ADM (19FP2): for pins AA/6G, 6H and 6J of the ADIRU2 and pins A/A, C and E of the connector receptacle

 - connect the electrical connector of the R total pressure ADM (19FP2).

 (b) If the voltages are OK:

 - disconnect the electrical connector of the R static pressure ADM (19FP6) 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 R static pressure ADM (19FP6) and the first terminal block: for pins A/A, C and E of the connector receptacle

 - connect the electrical connectors of the R total pressure ADM (19FP2) and the R static pressure ADM (19FP6).

 2 If the voltages are OK:
_
 - disconnect the electrical connector of the L static pressure ADM (19FP7) 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 connector receptacle of the L static pressure ADM (19FP7) and the first terminal block: for pins A/A, C and E of the connector receptacle

 - connect the electrical connectors of the L total pressure ADM (19FP2) and the R static pressure ADM (19FP6) and the L static pressure ADM (19FP7).

 b If the voltages are OK and if the fault continues:
_
 - replace the ADM-R TOTAL PRESSURE (19FP2) (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001). . If the fault continues: replace the ADM-R STATIC PRESSURE (19FP6).
