- replace the pushbutton switch 1884GP.
b If there is no continuity:
_
- do a check and repair the wiring between the: pushbutton switch (1884GP) connector C3 and the CB (1881GP) (Ref. ASM 29-19/01).
(c) If the fault continues:
- Replace the SOL VALVE-LEAKAGE MEAS, B (2150GP) (Ref. AMM TASK 29-19-51-000-002) and (Ref. AMM TASK 29-19-51-400-002).
(2) If the pressure is less than 1450 psi:
- do a check for external leakage and repair the components as necessary.
B. Do the fault confirmation procedure as given in Para. 3. to make sure that operation is correct.

R A. If the test gives the message HYD B ELEC PUMP OVHT on the upper ECAM DU:
R - disconnect the electrical connector (2075GJ-A) and look at the upper
R ECAM DU.
R (1) If the fault continues:
R - do a check of the wiring between the ELEC PUMP-B (2075GJ) connector
R A/F and the SDAC.
R (2) If the fault does not continue:
R - replace the ELEC PUMP-B (2075GJ) (Ref. AMM TASK 29-12-51-000-001)
R and (Ref. AMM TASK 29-12-51-400-001).
R NOTE : Replace the ELEC PUMP-B (2075GJ) with the ELEC PUMP-Y (3075GX)
