____ than 1 ohm (Ref. CMM 280111).
 (d) Push (in) or release (out) the P/BSW-4QE to change the actuator position.
 NOTE : This is done with motor 2 supplied through the connector
____ 5QE-B that is still connected to receptacle R2.
 (e) Do the step (d) again for the opposite condition.

 (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).
