Ian P Posted November 10 Report Share Posted November 10 I have noticed that when my trailer is attached and the ignition is off, the running lights on the trailer stay on. Is this normal? Quote Link to comment Share on other sites More sharing options...
lildisco Posted November 10 Report Share Posted November 10 Year & Model? I find that mine, not factory setup 2020 SEL AWD, comes on when parking lights are on when the doors open or close & stay on for a few seconds after the doors close then go off. That's probably due to the aftermarket trailer wiring kit, Curt, that ties into the the drivers side Taillight with a plug & play harness. I'm not sure about the OEM setup, but I imagine that it's similar. Quote Link to comment Share on other sites More sharing options...
Haz Posted November 10 Report Share Posted November 10 If your 2020 Edge SEL is equipped with the factory Class II Trailer Tow Package, the following Special Service Message, issued effective October 7, 2021, may apply to the issue you describe... Good luck! SSM 50175 2015-2021 Edge, 2016-2018 MKX, 2019-2021 Nautilus - Parking Lamps Stay On And/Or Trailer Lights Flicker With Vehicle Turned Off 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. 1 Quote Link to comment Share on other sites More sharing options...
