U0578Invalid Data Received From Seat Module K
- Generic OBD-II code · Network
- How the car detects it
- Ford assigns letter K to a defined seat: on the 2025 Lincoln Navigator, seat control module K (SCMK) is the rear left power seat module of the second row. Its software update SCMK-25.5.5.3 removed a short delay in seat operation and made the memory function of that seat store positions reliably. SSM 54226 adds a configuration case: second-row seats that would not slide fore and aft with B167F:11 in SCMK and/or SCML until both configuration apps were run. U0578 is set when SCMK frames arrive but contain implausible values such as seat position or switch status; U0277 is the lost-contact partner and U0579 the right-hand seat. No bulletin cites U0578. Expect a second-row seat that moves late, forgets memory positions or does not move at all.
