4. Fault IsolationSubtask 33-51-00-810-060-A ** ON A/C NOT FOR ALL
A. If the emergency lighting in the cabin does not come on:
Subtask 33-51-00-810-060-C ** ON A/C NOT FOR ALL - do the BITE-test of the Cabin Intercommunication Data-System (CIDS) AMM 23-73-00-740-005 and monitor the functions of the Forward Attendant Panel (FAP) (120RH),
- make sure that the FAP [120RH] operates correctly and replace it if necessary AMM 23-73-12-000-002 and AMM 23-73-12-400-002.
- do a check and repair as necessary the wiring between:
FAP (120RH) connector A/15 and EPSU (10WL) connector A/A or EPSU (11WL) connector A/A or EPSU (12WL) connector A/A or EPSU (13WL) connector A/A
ASM 335101 and ASM 335102.
A. If the emergency lighting in the cabin does not come on:
Subtask 33-51-00-710-071-A - do the interface and power-up test of the Cabin Intercommunication Data-System (CIDS) AMM 23-73-00-740-005 and monitor the functions of the Flight Attendant Panel (FAP) (120RH),
- make sure that the FAP [120RH] operates correctly and replace it if necessary AMM 23-73-12-000-007 and AMM 23-73-12-400-007.
- do a check and repair as necessary the wiring between:
FAP (120RH) connector A/15 and EPSU (10WL) connector A/A or EPSU (11WL) connector A/A or EPSU (12WL) connector A/A or EPSU (13WL) connector A/A
