**ON A/C 001-049, 051-099, 101-105, 151-199, 201-299,
A. Test for the Pax Call Lamps / Seatrow Identifier.
(1) Do the CIDS1/SIGN LAMP test through the CFDS (Ref. AMM TASK 23-73-00-710-033).
NOTE : An erroneous class 3 fault message will be recorded for each
____ LED PAX CALL LAMP / Seatrow Identifier (without bulbs), if the test of the related lamps is not deactivated in the CAM.
(2) Open at least one PAX-door to make sure that all Pax Call Lamps / Seatrow Identifiers come on.
R **ON A/C 106-149, 301-399, 401-499,
A. Test
(1) Do the CIDS Interface and Power-Up Test via the CFDS (Ref. AMM TASK 23-73-00-740-010).
(2) Do the Operational Test of the Cabin LED Lamps via the CFDS (Ref. AMM TASK 23-73-00-710-035).

4. Fault Isolation
_______________
A. If the test gives a different maintenance message, do the trouble shooting procedure related to the maintenance message.
**ON A/C 001-049, 051-099, 101-105, 151-199, 201-299,
B. For Pax Call Lamps / Seatrow Identifier with bulbs: If the CIDS1/SIGN LAMP test gives the maintenance message PAX CALL LAMP XX and the lamp does not come on:
NOTE : XX identifies the location of the faulty unit:
____ - SR: ..L/R
- replace the related INDICATOR LIGHT-PASSENGER CALL/SEAT ROW IDENTIFIER (505RH) and/or INDICATOR LIGHT-PASSENGER CALL/SEAT ROW IDENTIFIER (506RH) (Ref. AMM TASK 23-73-14-000-006) and (Ref. AMM TASK 23-73-14-400-006).
