Official summary
Some 2015-2021 Edge, 2016-2018 MKX, and 2019-2021 Nautilus vehicles may exhibit the parking lamps stay on and/or the trailer lights flicker with vehicle turned off when a trailer is connected to the vehicle. This may be due to the software in the trailer module (TRM). To correct the condition, reprogram the TRM with the latest software of the appropriate Ford diagnostic scan tool. Use causal part 19H332 and applicable labor times from Section 10 of the Service Labor Time Standards (SLTS) Manual.
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.
