 3. Fault Confirmation
__________________

 A. Job Set-up
 (1) Aircraft Maintenance Configuration
 (a) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).

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

 B. Make sure that this(these) circuit breaker(s) is(are) closed:
 -------------------------------------------------------------------------------PANEL DESIGNATION IDENT. LOCATION -------------------------------------------------------------------------------
121VU EIS/SLIDES/ARM AND WARN/GND 13WN P10
 C. Test
 (1) On the ECAM control panel:

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

 (2) Make sure that the SLIDE indication is not shown on the DOOR/OXY page when the L. forward escape-slide handle is in the SLIDE ARMED position.

 4. Fault Isolation
_______________
 A. If the test confirms the fault:
 - disconnect the connector A of the handle proximity switch (4WN1)

 - install the jumper wire between the pins A/B, C of the handle proximity switch (4WN1) (Ref. ASM 52-73/01)

 - do the test given in Para 3.B.

 (1) If the test confirms the fault:
 - replace the IND LT-SLIDE ARMED, FWD L DOOR (1WN1) (Ref. AMM TASK 52-73-21-000-002) and (Ref. AMM TASK 52-73-21-400-002).
 (a) If the fault continues:

 - replace the RELAY-PWR SPLY SWITCH OVER (12WN) (Ref. ASM 52-73/01).

 (b) If the fault continues:

 - do a check for a ground signal at pin A/C of the proximity switch (4WN1) (Ref. ASM 52-73/01).
 1 If there is a ground signal:
_
 - do a check and repair the wiring from the proximity switch (4WN1) to the indicator light (1WN1) pin A/B to pin H (Ref. ASM 52-73/01)

 - do a check and repair the wiring from the indicator light (1WN1) to the SDAC - 1(2) (1WV1(2)) pin K to pin AA (AD)/12A,12G (Ref. ASM 52-73/01) and (Ref. ASM 52-73/01).
 2 If there is no ground signal:
_
 - repair the wiring from the proximity switch (4WN1) pin A/C to the ground terminal (Ref. ASM 52-73/01).
