- replace the CT-Y ELEC PUMP (3807GX) (Ref. AMM TASK 29-24-15-000-001) and (Ref. AMM TASK 29-24-15-400-001).
b If the fault continues:
_
- replace the DET-PHASE UNBALANCE, Y ELEC PUMP (3808GX) (Ref. AMM TASK 29-24-16-000-001) and (Ref. AMM TASK 29-24-16-400-001).
c If the fault continues:
_
- do a check of the wiring between: the ELEC PUMP-Y (3075GX) connector A/A, A/B, A/C and the CB (3801GX) (Ref. ASM 29-24/01).
d If the fault continues:
_
- do a check of the wiring between: the ELEC PUMP-Y (3075GX) connector A/A, A/B, A/C and the CB (3802GX) (Ref. ASM 29-24/01).
e If there are no 28 VDC:
_
- do a check of the wiring between: the DET-PHASE UNBALANCE, Y ELEC PUMP (3808GX) connector A/F and the CB (3803GX) and repair as necessary (Ref. ASM 29-24/01).
B. Do the test as given in Para. 3. A. to make sure that the operation is correct.

A. Do the operational test of the electric pump of the Yellow hydraulic system (Ref. AMM TASK 29-24-00-710-001).
4. Fault Isolation
_______________
A. If the test gives the message HYD Y ELEC PUMP OVHT:
- disconnect the electrical connector (3075GX-A) and look at the upper ECAM DU.
(1) If the fault continues:
- do a check of the wiring between: the ELEC PUMP-Y (3075GX) connector A/F and the SDAC and repair as necessary (Ref. ASM 29-24/01).
(2) If the fault does not continue:
- replace the ELEC PUMP-Y (3075GX) (Ref. AMM TASK 29-24-51-000-001) and (Ref. AMM TASK 29-24-51-400-001).

_______________
A. If the test gives: the HYD Y SYS LO PR on the upper ECAM DU, normal pressure for the Yellow system (approximately 3000 psi) on the HYD page of the lower ECAM DU, and the Yellow electric pump operates continuously:
- replace the RELAY-TIME (6MJ).
NOTE : If the CFDS fault message ATA 29-32-12 AFS: HYD Y 3151GN comes
____ into view, ignore it, because it has no relation to this failure.
B. Do the test as given in Para. 3. A. to make sure that the operation is correct.
