3. Fault Confirmation
Subtask 52-21-00-710-061-A ** ON A/C NOT FOR ALL
A. Test
   (1) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only)
AMM 31-60-00-860-001.
   (2) Remove and install the cover flap of the RH emergency exit hatch (refererd to as hatch).
   (3) Look for the fault indications at the door page of the lower ECAM DU.
4. Fault Isolation
Subtask 52-21-00-810-058-A ** ON A/C NOT FOR ALL
A. When the cover flap is correctly installed and the door page of the lower ECAM DU shows the symbol for the hatch and the message EMER EXIT in amber:
   (1) If the fault continues:
  • make an electrical connection between the:
    PROX SW-HANDLE FLAP, R AFT EMER EXIT [21WV2] connectors A/A and A/B ASM 315405.
     (a) If the message EMER EXIT goes off and the symbol for the hatch changes to green:
     (b) If the fault continues:
  • do a check for 28 VDC between the:
    PROX SW-HANDLE FLAP, R AFT EMER EXIT [21WV2] connectors A/A and A/C ASM 315405.
       1 If there is 28 VDC:
  • do a check and repair the wiring between:
    the PROX SW-HANDLE FLAP, R AFT EMER EXIT [21WV2] connector A/B and the IND LT-SLIDE ARMED, R EMER EXIT [2WN2] connector A/E ASM 315405.
       2 If there is no 28 VDC:
  • do a check and repair the wiring between the:
    PROX SW-HANDLE FLAP, R AFT EMER EXIT [21WV2] connector A/A and the IND LT-SLIDE ARMED, R EMER EXIT [2WN2] connector A/R ASM 315405.
    PROX SW-HANDLE FLAP, R AFT EMER EXIT [21WV2] connector A/C and ground ASM 315405.
     (c) If the fault continues:
Subtask 52-21-00-710-062-A ** ON A/C NOT FOR ALL
B. Do a test as given in Para. 3.A. to make sure that the operation is correct.
5. Close-up
Subtask 52-21-00-860-055-A ** ON A/C NOT FOR ALL
A. De-energize the aircraft electrical circuits
AMM 24-41-00-862-002.
