  • install the jumper wire between pins B and C of the connector (13WV1-A) ASM 315405
  • do the test given in Para. 3.C.
     (a) On the Door/Oxy page, if the CABIN indication comes into view green:
  • remove the jumper wire between pins B and C of the connector (13WV1-A)
  • connect the connector of the handle proximity switch (13WV1)
  • adjust the handle proximity switch (13WV1) with the door checking tool AMM 52-71-00-820-002 or with the ECAM system AMM 52-71-00-820-002.
       1 On the Door/Oxy page, if the CABIN indication comes into view amber:
     (b) On the Door/Oxy page, if the CABIN indication comes into view amber:
  • remove the jumper wire between pins B and C of the connector (13WV1-A)
  • connect the connector of the handle proximity switch (13WV1)
  • do a check for 28VDC between pins A and D of the hook proximity switch (11WV1) ASM 315405.
       1 If there is no 28VDC:
  • repair the wiring as necessary.
       2 If there is 28VDC:
