U0579Invalid Data Received From Seat Module L
- Generic OBD-II code · Network
- How the car detects it
- Seat control module L (SCML) is Ford's right-hand counterpart to SCMK: on the 2025 Lincoln Navigator it runs the passenger-side power seat of the second row. Ford pushed SCML-25.5.5.3 over the air so that this seat keeps its memory settings consistently; the release note page itself is headed with the PCM by mistake but names seat control module L in the text. In SSM 54226, B167F:11 could sit in SCML when the second-row switch failed to move the seat, and the SCML configuration app was the fix. U0579 means frames from SCML reach other modules with implausible content; U0278 stands for missing frames, U0578 for the left seat module. No bulletin cites U0579. The right second-row seat may stop moving or lose its stored positions.
