__________________
A. Do the operational test of the lavatory lighting (Ref. AMM TASK 33-24-00-710-001)
4. Fault Isolation
_______________
A. If the test confirms the fault:
- do a check of the LAVATORY LIGHTING-RELAY (2LQ) and replace it if necessary.
(1) If the fault continues:
- replace the ATTENDANT PANEL-FORWARD (120RH) (Ref. AMM TASK 23-73-12-000-001) and (Ref. AMM TASK 23-73-12-400-001).
(2) If the fault continues:
- do a check and repair the wiring if necessary between: LAVATORY LIGHTING RELAY 2LQ connector A/X1 and FWD ATTENDANT PANEL (120RH) connector A/14, LAVATORY LIGHTING RELAY 2LQ connector A/A2 and CB 1LQ, LAVATORY LIGHTING RELAY 2LQ connector A/X2 and GND (Ref. ASM 33-24/01).
(3) If the fault continues:
- do the trouble shooting procedures for the FWD ATTENDANT PANEL (120RH) (Ref. TASK 23-73-00-810-838).

4. Fault Isolation
_______________
A. If the test confirms the fault:
- adjust the position of the related LAV OCCPD SWITCH in the door frame of the lavatory (Ref. AMM TASK 33-26-11-400-001).
(1) If the fault continues:
- do a check of the related LAV OCCPD SWITCH and replace it if necessary (Ref. AMM TASK 33-26-11-000-001) and (Ref. AMM TASK 33-26-11-400-001).
(2) If the fault continues:
- replace the related BALLAST UNIT (Ref. AMM TASK 33-21-11-000-001) and (Ref. AMM TASK 33-21-11-400-001).
(3) If the fault continues:
- do a check and repair the wiring if necessary between the related: BALAST UNIT pin D and the LAV OCCPD SWITCH pin NF (Ref. ASM 33-24/01) and (Ref. ASM 33-26/01).
