I know that it's been a while since your post, but was wondering if this fix will definitely fix the truck's horn sounding when a trailer is connected and the truck is locked?
maybe, but it’s not a scalable or correct solution to the problem. there’s a sore are update that fixes this issue that can be applied by your dealer.
Unfortunately, I've had the truck, 2022 F150 built in May, 2022, at the dealers for a couple days and they say that the SSM doesn't apply to my VIN. My dealer is not the sharpest tack in the box. I think they're wrong and I may get it done in the next few months when I have to bring the truck back in for 2 recalls for which Ford has no parts right now. I wanted a quick, possible temporary, solution to the problem now. If I could put two incadescent lights in the brake circuit of the trailer, it would be an easy fix.
Yes this still has been the fix for me, just add a regular halogen/incandescent light or maybe even some resistors to the brake/signal circuit and you will stop setting the alarm off when locking your doors If you watch your trailer lights after you lock your doors you will notice after about 30sec your brake lights will light up then alarm will go off, that is the truck testing the circuit in which my case the led lights didn’t have enough resistance for the truck to recognize it’s still plugged in so it was thinking someone unplugged the trailer and stealing it Hope this helps you too!
Great, I've bought a couple of small amber incadescent lights that I'll attach to the side of the trailer and hook them up to the brake/blinker circuit. I hope this works.
I have a question about my truck's false trailer theft alarm. I just received notice that an OTA update 22S17 will be done to update the software on my truck's trailer relay module. I know this update is for fixing the issue with braking of a towed vehicle. My question is, will it also fix the problem with false alarms on the trailer theft alarm mentioned above?
