a If there is no continuity in a SEB:
_
- replace that SEAT ELECTRONIC BOX (100MKxx) (Ref. AMM TASK 23-33-46-000-001) and (Ref. AMM TASK 23-33-46-400-001).
4 If the fault continues:
_
- do a check and repair as necessary the wiring between checked SEBs (100MKxx) (Ref. ASM 23-33/03):
- the SEB (100MKxx) connector P1/6 and the SEB (100MKxx) connector P2/6.
- 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.
5 If the fault continues:
_
- do a check and repair as necessary the wiring between the SEB (100MKxx) nearest to the WDB (50MKx) that serves the checked SEB(s) (100MKxx) and that WDB (50MKx) (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.
6 If the fault continues:
_
- do a check and repair as necessary the wiring between all WDBs (50MKx) from the WDB (50MKx) that serves the seat row YY and the WBD (50MKx) that serves the SEB (100MKxx) backward of the seat row YY (Ref. ASM 23-33/02):
- the WDB (50MKx) connector A/13 and the WDB (50MKx) connector D/13.
- the WDB (50MKx) connector A/14 and the WDB (50MKx) connector D/14.
- the WDB (50MKx) connector A/15 and the WDB (50MKx) connector D/15.

- the WDB (50MKx) connector A/1 and the WDB (50MKx) connector D/1.
- the WDB (50MKx) connector A/2 and the WDB (50MKx) connector D/2.
If the fault continues:
- do a continuity check on all SEBs (100MKxx) on the right side of the cabin from the seat row behind the seat row YY to the seat row next to the WDB (50MKx) that serves the SEBs (100MKxx) above between:
- the SEB (100MKxx) connector J1/6 and the SEB (100MKxx) connector J2/6.
a_ If there is no continuity:
- replace that/these SEAT ELECTRONIC BOX(es) (100MKxx)
above (Ref. AMM TASK 23-33-46-000-001) and (Ref. AMM TASK
23-33-46-400-001).
If the fault continues:
- do a check and repair as necessary the wiring between the checked SEBs (100MKxx) behind the seat row YY (Ref. ASM 23-33/03):
- the SEB (100MKxx) connector P1/6 and the SEB (100MKxx) connector P2/6.
If the fault continues:
- do a check and repair as necessary the wiring between the SEB (100MKxx) nearest to the WDB (50MKx) that serves the checked SEB (100MKxx) and that WDB (50MKx) (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.
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).
