(e) If the fault continues:
- replace the SEAT ELECTRONIC BOX (100MKxx) in the first seat row on the left side of the cabin (Ref. AMM TASK 23-33-46-000-001) and (Ref. AMM TASK 23-33-46-400-001).
(f) If the fault continues:
- replace the WALL DISCONNECT BOX (50MKx) that serves the SEB (100MKxx) in the first seat row on the left side of the cabin (Ref. AMM TASK 23-33-47-000-001) and (Ref. AMM TASK 23-33-47-400-001).
(g) If the fault continues and:
(h) If the fault continues:
- do the para. above again until the WDB (50MKx) next to the MUX-PES, MAIN (8MK) is replaced (Ref. AMM TASK 23-33-47-000-001) and (Ref. AMM TASK 23-33-47-400-001).
(i) If the fault continues:
1_ If another WDB (50MKx) is connected in line to the MUX-PES,
MAIN (8MK) on the left side of the cabin :
- replace that WALL DISCONNECT BOX (50MKx) (Ref. AMM TASK 23-
33-47-000-001) and (Ref. AMM TASK 23-33-47-400-001).
- replace the MUX-PES, MAIN (8MK), (Ref. AMM TASK 23-33-31-000-001) and (Ref. AMM TASK 23-33-31-400-001).
D. Do the test given in Para 3.B.

__________________
A. Do the bite test of the Cabin Intercommunication Data System (CIDS) (Ref. AMM TASK 23-73-00-740-003).
4. Fault Isolation
_______________
A. Different and additional maintenance messages R
R (1) If the test gives a different maintenance message, do the trouble R shooting procedure related to the maintenance message.
(2) If the test gives an additional maintenance message and that message shows a PES bus failure:
- do the related trouble shooting procedure for that PES bus failure first.
B. If the test gives the maintenance message 23-33-46/SEB XXL:
- make sure that a SEB TERMINATOR (101MKxx) is connected to the SEAT ELECTRONIC BOX (100MKxx) (SEB) in the seat row XX on the left 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 seat row XX on the left side of the cabin. (Ref. ASM 23-33/03).
(a) If the fault continues:
- replace the SEAT ELECTRONIC BOX (100MKxx) (SEB) in the seat row XX on the left side of the cabin (Ref. AMM TASK 23-33-46-000-001) and (Ref. AMM TASK 23-33-46-400-001).
(b) If the fault continues:
- make sure that the SEB (100MKxx) in the seat row XX on the left side of the cabin is connected to a WALL DISCONNECT BOX (50MKx) (WBD).
1 If that is true:
_
- do a check and repair as necessary the wiring between (Ref. ASM 23-33/03):
- the WDB (50MKx) connector P1/7 and in the seat row XX the SEB (100MKxx) connector P2/7.
- the WDB (50MKx) connector P1/8 and in the seat row XX the SEB (100MKxx) connector P2/8.
- the WDB (50MKx) connector P1/5 and in the seat row XX the SEB (100MKxx) connector P2/5. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 COMMUNICATIONS 通讯1(120)
