2016 F150 brake/turn signal issue
I just had the wiring harness installed on my F150. Just like on my previous Jeep Wrangler, the brake and turn signals do not function separately while being towed. On the Jeep, I thought it was because there was only one light assembly on each side, rather than separate brake and turn signal lights inside the case. Upon further inspection, I see that the F150's tail lights are indeed the same.
The shop that installed the wiring harness said that there's only one wire going to the tail light assembly on each side. Because a CAN bus multiplex system is used, there's no way to physically separate the brake and turn signal light function without some way to decode the multiplexed signal for each function. They checked with Demco, who said that this is something they're working on. In the meantime, if a turn signal is on and the brakes are pressed, the brake light bypasses the flashing turn signal so the tail light is on solid. It's not a huge deal as the rear coach lights and turn signals are fairly high and very visible, but it's not ideal. I will generally have a full-size HD touring bike in the bed of the truck so the CHMSL will not be visible.
Has anyone run into this before, and if so, are you aware of any workaround?
