12 If the fault continues:
__
 - replace the WALL DISCONNECT BOX (50MKx) that serves the last replaced SEB (100MKxx) (Ref. AMM TASK 23-33-47-000-001) and (Ref. AMM TASK 23-33-47-400-001).
 13 If the fault continues and:
__
 a If another WDB (50MKx) is connected in line to the seat row
_ YY on the right side of the cabin:
 - replace the next WALL DISCONNECT BOX (50MKx) in line to the SEB (100MKxx) in the seat row YY (Ref. AMM TASK 23-33-47-000-001) and (Ref. AMM TASK 23-33-47-400-001).
 14 If the fault continues:
__
 - do the para. above again until the WALL DISCONNECT BOX (50MKx) that serves the SEB (100MKxx) in the seat row YY on the right side of the cabin is replaced (Ref. AMM TASK 23-33-47-000-001) and (Ref. AMM TASK 23-33-47-400-001).
 C. Do the test given in para. 3.A.

 3. Fault Confirmation
__________________
 A. Reset of the PES System
 (1) On the audio panel (123RH) of the Forward Attendant Panel (120RH) (FAP) push the PES ON/OFF membrane switch to de-energize the PES.

 (2) On the audio panel (123RH) of the FAP (120RH) push the PES ON/OFF membrane switch to energize the PES.

 NOTE : The maximum PES (music) power-on initialization time is up to
____ 10 minutes. This includes the transfer of the seat layout from the CIDS CAM.

 B. Do the bite test of the cabin intercommunication data system (CIDS) (Ref. AMM TASK 23-73-00-740-003).
 4. Fault Isolation
_______________
R
R A. If the test gives a different maintenance message, do the trouble R shooting procedure related to the maintenance message.
 B. If the test gives the two maintenance messages 23-33-54/BUS S-MR and 23-33-54/BUS S-ML:
 - replace the MUX-PES, MAIN (8MK), (Ref. AMM TASK 23-33-31-000-001) and (Ref. AMM TASK 23-33-31-400-001).
 C. If the test gives the maintenance message 23-33-54/BUS S-MR:
 - make sure that a SEB TERMINATOR (101MKxx) is connected to the SEAT ELECTRONIC BOX (100MKxx) (SEB) in the last seat row on the right side of the cabin.
 (1) If that is true:
 - do a check for the functional condition and the correct installation of the SEB TERMINATOR (101MKxx) on the SEB (100MKxx) in the last seat row on the right side of the cabin (Ref. ASM 23-33/03).
 (a) If the fault continues and:
 1 If another/other SEB TERMINATOR(s) (101MKxx) is/are connected
_ to a/the WALL DISCONNECT BOX(es) (50MKx) (WDB) in line to the WDB (50MK6):
 - repeat the check above on that/these SEB TERMINATOR(s) (101MKxx) (Ref. ASM 23-33/03).
 (b) If the fault continues:

 - do a check for the functional condition and the correct installation of the TERMINATION PLUG (51MK1) on the WDB (50MK6) (Ref. ASM 23-33/02).

 (c) If the fault continues:

 - do a continuity check on all SEBs (100MKxx) on the right side of the cabin from the last seat row to the seat row next to the WDB (50MKx) that serves the SEBs (100MKxx) above between:
