 B. Test

 (1) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001)

 (2) Remove and install the cover flap of the LH-AFT emergency-exit hatch (referred to as the hatch) (Ref. AMM TASK 25-23-47-000-001) and (Ref. AMM TASK 25-23-47-400-001).

 NOTE : This makes sure that the target bracket of the cover flap is
____ in its correct installation position.
 (3) On the DOOR/OXY page of the lower ECAM DU, look for the possible fault indication.
 4. Fault Isolation
_______________
 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:
 - make sure that the adjustment of the PROX SW-HANDLE FLAP, L AFT EMER EXIT (21WV1) is correct (Ref. AMM TASK 52-71-13-400-001).
 (1) If the fault continues:
 - install the jumper wire between the: PROX SW-HANDLE FLAP, L AFT EMER EXIT (21WV1) connectors A/C and A/B (Ref. ASM 31-54/05).
 (a) If the message EMER EXIT goes off and the symbol for the hatch changes to green:

 - replace the PROX SW-HANDLE FLAP, L AFT EMER EXIT (21WV1) (Ref. AMM TASK 52-71-13-000-001) and (Ref. AMM TASK 52-71-13-400-001).

 (b) If the message EMER EXIT remains on in amber:

 - do a check for 28 VDC between the: PROX SW-HANDLE FLAP, L AFT EMER EXIT (21WV1) connectors A/A and A/C (Ref. ASM 31-54/05).
 1 If there is 28 VDC:
_
 - do a check and repair the wiring between: the PROX SW-HANDLE FLAP, L AFT EMER EXIT (21WV1) connector A/B and the IND LT-SLIDE ARMED, L EMER EXIT (2WN1) connector A/E (Ref. ASM 31-54/00).
 2 If there is no 28 VDC:
_
 - do a check and repair the wiring between the: PROX SW-HANDLE FLAP, L AFT EMER EXIT (21WV1) connector A/A and the IND LT-SLIDE ARMED, L EMER EXIT (2WN1) connector A/R (Ref. ASM 31-54/00). PROX SW-HANDLE FLAP, L AFT EMER EXIT (21WV1) connector A/C and ground (Ref. ASM 31-54/05).

 May 01/05 CES (2) If the fault continues:

 - replace the IND LT-SLIDE ARMED, L EMER EXIT (2WN1) (Ref. AMM TASK 52-73-21-000-003) and (Ref. AMM TASK 52-73-21-400-003).
