push the DOOR key to get the DOOR/OXY page.

(3) On the DOOR/OXY page of the lower ECAM DU, look for possible fault indications.

4. Fault Isolation
Subtask 52-22-00-810-050-A ** ON A/C NOT FOR ALL

A. If the test gives the amber EMER EXIT indication of the LH FWD emergency exit door:

do a check and adjust as necessary the PROX SW-HOOK, L FWD EMER EXIT [59WV1] AMM 52-71-00-820-005

(1) If the fault continues:

install the jumper wire between the:
PROX SW-HOOK, L FWD EMER EXIT [59WV1] connector A/C and A/B ASM 315405.

(a) If the message EMER EXIT goes off:

replace the PROX SW-HOOK, L FWD EMER EXIT [59WV1] AMM 52-71-13-000-003 and AMM 52-71-13-400-003.
remove the jumper wire.

(b) If the message EMER EXIT remains on:

remove the jumper wire.
do a check for a ground signal at the PROX SW-HOOK, L FWD EMER EXIT [59WV1] connector A/C ASM 315405.

1 If there is a ground signal:

do a check and repair the wiring between:
the PROX SW-HOOK, L FWD EMER EXIT [59WV1] connector A/B and the SDAC-1 [1WV1] or SDAC-2 [1WV2] connector AA/11C ASM 315405.

a If the fault continues:

do a check for 28 VDC between the:
the PROX SW-HOOK, L FWD EMER EXIT [59WV1] connector A/A and A/D ASM 315405.

b If there is 28VDC:

replace the PROX SW-HOOK, L FWD EMER EXIT [59WV1] AMM 52-71-13-000-003 and AMM 52-71-13-400-003.

c If there is no 28VDC:

check and repair the wiring between:
the PROX SW-HOOK, L FWD EMER EXIT [59WV1] connector A/A and CB C/B-EIS/SDAC1 AND 2/DOOR/DET/PAX [48WV] , and the connector PROX SW-HOOK, L FWD EMER EXIT [59WV1] A/D and ground.

2 If there is no ground signal:

do a check for continuity between:
the IND LT-SLIDE ARMED, FWD L EMERGENCY EXIT [21WN1] connectors A/F and A/G ASM 315405.

a If there is no continuity:

replace the IND LT-SLIDE ARMED, FWD L EMERGENCY EXIT [21WN1] AMM 52-73-22-000-003 and AMM 52-73-22-400-003

do a check and adjust as necessary the PROX SW-HANDLE FLAP, L FWD EMER EXIT [19WV1] AMM 52-71-00-820-007

(3) If the fault continues:

install the jumper wire between the:
PROX SW-HANDLE FLAP, L FWD EMER EXIT [19WV1] connector A/C and A/B ASM 315405.

(a) If the message EMER EXIT goes off:

replace the PROX SW-HANDLE FLAP, L FWD EMER EXIT [19WV1] AMM 52-71-13-000-003 and AMM 52-71-13-400-003.
remove the jumper wire.

(b) If the message EMER EXIT remains on:

remove the jumper wire.
do a check and repair the wiring between:
the PROX SW-HANDLE FLAP, L FWD EMER EXIT [19WV1] connector A/C and ground ASM 315405.

do a check for 28VDC between the:
PROX SW-HANDLE FLAP, L FWD EMER EXIT [19WV1] connector A/A and A/D ASM 315405.

1 If there is no 28VDC:

do a check for a continuity between:
the IND LT-SLIDE ARMED, FWD L EMERGENCY EXIT [21WN1] connectors A/S and A/A ASM 315405.

a If there is continuity:

do a check and repair the wiring between:
IND LT-SLIDE ARMED, FWD L EMERGENCY EXIT [21WN1] connector A/A and CB C/B-EIS/SLIDES/ARM AND WARN/GND [13WN] , PROX SW-HANDLE FLAP, L FWD EMER EXIT [19WV1] A/A and IND LT-SLIDE ARMED, FWD L EMERGENCY EXIT [21WN1] A/S, PROX SW-HANDLE FLAP, L FWD EMER EXIT [19WV1]

b If there is no continuity:
