(f) If the actuator-5QE position indication microswitches:
- do not pass all the tests given in step (c), replace the ACTUATOR-FUEL CROSSFEED VALVE (5QE) (Ref. AMM TASK 28-23-51-000-001) and (Ref. AMM TASK 28-23-51-400-001)
- pass all the tests given in step (c), are serviceable, do step (2).
(2) If the fault continues:
(a) Do a check (Ref. ESPM 20-00-00) of the aircraft wiring (Ref. ASM 28-23/01) between:
- the connector 5QE-A, pin D and the SDAC-1, rack connector 1WV1-A, pin 13H
- the connector 5QE-A, pin D and the SDAC-2, rack connector 1WV2-A, pin 13H
- the connector 5QE-A, pin B and the SDAC-1, rack connector 1WV1-A, pin 14H
- the connector 5QE-A, pin B and the SDAC-2, rack connector 1WV2-A, pin 14H.
(b) Repair all the unserviceable wiring and connectors (Ref. ESPM 20-00-00).
(c) Do the test in Para. 3.A.
(3) If the fault continues, trouble shoot the ECAM display system (Ref. TSM 31-00-00).
