15__ If the fault continues:
- do para. above again until the WALL DISCONNECT BOX (50MKx)
that serves the SEB (100MKxx) in the seat row XX 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).
(2) If the position of the SEB (100MKxx) in the seat row YY is correctly identified:
- Make sure that the SEB (100MKxx) behind the seat row YY is connected to the SEB (100MKxx) in the seat row YY on the right side of the cabin.
(a) If that is true:
- do a check and repair as necessary the wiring between the SEB (100MKxx) behind the seat row YY and the SEB (100MKxx) in the seat row YY on the right side of the cabin. (Ref. ASM 23-33/03):
- the SEB (100MKxx) connector P1/9 and the SEB (100MKxx) connector P2/9.
- the SEB (100MKxx) connector P1/5 and the SEB (100MKxx) connector P2/5.
- the SEB (100MKxx) connector P1/7 and the SEB (100MKxx) connector P2/7.
- the SEB (100MKxx) connector P1/8 and the SEB (100MKxx) connector P2/8.
1 If the fault continues:
_
- replace the SEAT ELECTRONIC BOX (100MKxx) in the seat row YY on the right side of the cabin (Ref. AMM TASK 23-33-46-000-001) and (Ref. AMM TASK 23-33-46-400-001).
2 If the fault continues:
_
- replace the SEAT ELECTRONIC BOX (100MKxx) in the seat row behind the seat row YY on the right side of the cabin (Ref. AMM TASK 23-33-46-000-001) and (Ref. AMM TASK 23-33-46-400-001).
(b) If a WALL DISCONNECT BOX (50MKx) is connected directly to the SEB (100MKxx) in the seat row YY, instead of the SEB (100MKxx) in the seat row behind the seat row YY on the right side of the cabin and:
1 If a SEB TERMINATOR (101MKxx) is connected to the SEB
_ (100MKxx) in the seat row behind the seat row YY:
- do a check for the functional condition and the correct installation of that SEB TERMINATOR (101MKxx) (Ref. ASM 23-33/03).
2 If the fault continues and:
_
a If another /other SEB TERMINATOR(s) (101MKxx) is/are
_ connected to a/the WDB(s) (50MKx) in line to the SEB (100MKxx) in the seat row behind the seat row YY:
- do the check above again on that/these SEB TERMINATOR(s) (101MKxx) (Ref. ASM 23-33/03).
3 If the fault continues:
_
- do a check and repair as necessary the wiring between the SEB (100MKxx) in the seat row YY and the connected WDB (50MKx) on the right side of the cabin (Ref. ASM 23-33/03):
- the WDB (50MKx) connector P1/6 and the SEB (100MKxx) connector P2/6.
- the WDB (50MKx) connector P1/9 and the SEB (100MKxx) connector P2/9.
- the WDB (50MKx) connector P1/5 and the SEB (100MKxx) connector P2/5.
- the WDB (50MKx) connector P1/7 and the SEB (100MKxx) connector P2/7.
- the WDB (50MKx) connector P1/8 and the SEB (100MKxx) connector P2/8.
4 If the fault continues:
_
- continue with para. 4.B.(2)(c)6_.
(c) If a SEB TERMINATOR (101MKxx) is connected to the SEB (100MKxx) in the seat row YY, instead of the SEB (100MKxx) in the seat row behind the seat row YY on the right side of the cabin:
- do a check for the functional condition and the correct installation of the SEB TERMINATOR (101MKxx) on the SEB (100MKxx) in the seat row YY (Ref. ASM 23-33/03).
1 If the fault continues and:
_
a If a SEB TERMINATOR (101MKxx) is connected to the SEB
_ (100MKxx) in the seat row behind the seat row YY:
- do a check the functional condition and correct installation of that SEB (100MKxx) (Ref. ASM 23-33/03).
2 If the fault continues and:
_
a If another/other SEB TERMINATOR(s) (101MKxx) is/are
_ connected to a/the WDB(s) (50MKx) in line to the SEB (100MKxx) in the seat row behind the seat row YY:
- do the check above again on that/these SEB TERMINATOR(s) (101MKxx) (Ref. ASM 23-33/03).
