A. If during the test the E-pump symbol on the HYD page of the lower ECAM DU shows LO in amber color and the system pressure is correct:
- replace the PRESSURE SWITCH-ELECTRIC PUMP 2074GJ (Ref. AMM TASK 29-12-17-000-001) and (Ref. AMM TASK 29-12-17-400-001).
B. If after the test the E-pump symbol on the HYD page of the lower ECAM DU shows IN-Line in green color:
- replace the PRESSURE SWITCH-ELECTRIC PUMP 2074GJ (Ref. AMM TASK 29-12-17-000-001) and (Ref. AMM TASK 29-12-17-400-001).
C. If, after the test, the link from the E-pump to the RAT on the HYD page of the lower ECAM DU is displayed in green color with the Blue E-pump in off position:
(1) Replace the PRESSURE SWITCH-ELECTRIC PUMP 2074GJ (Ref. AMM TASK 29-12-17-000-001) and (Ref. AMM TASK 29-12-17-400-001).

(2) If the fault continues:
(a) Do a check of the wiring and/or the electrical connector (2074GJ-A) of the PRESSURE SWITCH-ELECTRIC PUMP 2074GJ for correct condition (Ref. ASM 29-12/01).
(b) If necessary, repair the wiring and /or the electrical connector (2074GJ-A) of the PRESSURE SWITCH-ELECTRIC PUMP 2074GJ (Ref. ASM 29-12/01).
D. Do the test given in Para. 3

3. Fault Confirmation__________________
A. Do the operational test of the electric pump of the Blue hydraulic system (Ref. AMM TASK 29-12-00-710-001).
4. Fault Isolation_______________
A. If, during the test, the operation of the flight controls is correct, but the HYD page on the ECAM lower DU shows for the Blue hydraulic system the subsequent condition: the system pressure indication in amber (less than 1450 PSI), the system pressure identification (BLUE) in white, the system arrow in green. - replace the PRESSURE TRANSDUCER-HYDRAULIC (2065GN) (Ref. AMM TASK 29-32-11-000-002) and (Ref. AMM TASK 29-32-11-400-002).
