Official summary
Some 2020 F-150 Lariat vehicles equipped with the snow plow prep package may exhibit the snow plow button illuminating when you press the start/stop deactivation button, and the start/stop deactivation indicator illuminating when you press the snow plow button. Both features otherwise function correctly, and the correct messages illuminate in the message center when pressing either button. This may be due to incorrect switch circuitry. To correct the condition, follow the Service Procedure steps to swap circuit pin locations.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
