TheStuffz Posted April 11, 2020 Report Share Posted April 11, 2020 Hope this is right place to put this thread. 2019 Edge SEL AWD with factory hitch and 4 pin connector. I have noticed a few times while towing different trailers that the the lights on the trailer will randomly come on and stay on for awhile even with the Edge off and not being used. It has the keyless entry and start. I hooked up a trailer to go to the landfill the next day and later that night the trailer lights are on (clearance lights). Lights for the trailer have a light-up connector that tells you what lights are getting power etc and that will light up at the same time the clearance lights turn on. Edge is off, no lights on the Edge. Doors are locked. I noticed this when the Edge was fairly new, month or so and under 4k kms. Now its 6 months old and 17k kms and the 4 pin terminal is badly corroded... it has been covered when not in use. I have looked through the dash options and I cannot find any settings regarding trailers or lighting for them? Quote Link to comment Share on other sites More sharing options...
Gadgetjq Posted April 11, 2020 Report Share Posted April 11, 2020 You appear to be well within the warranty period, take it to your Ford dealer for a troubleshoot. There could be something wrong in the trailer module (behind the passenger side cargo panel) or ???? The dealer will have the tools to find the issue.

dajo2012 Posted April 12, 2020 Report Share Posted April 12, 2020 I have the same issue with my ST. The only way I can be sure the trailer lights are off is to unplug. I have noticed that some of the time they are on very dim also. No problems while engine running or driving. My trailer has LED lights.

TheStuffz Posted April 15, 2020 Author Report Share Posted April 15, 2020 hmm. My first trailer was a small enclosed with clearance lights all around top and bottom. Second has just rear tail lights. Both trailers are incandescent bulbs. I just got it back from dealer yesterday for a new torque converter. Will look through the paperwork to see if they even looked at it.

ebank Posted May 1, 2022 Report Share Posted May 1, 2022 I was loading a U-haul connected to my ST last week and I saw the lights go on on the trailer for no reason. I didn't think much of it at the time, then I saw this thread. Quote Link to comment Share on other sites More sharing options...
Haz Posted May 23, 2022 Report Share Posted May 23, 2022 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.
