Backup alarm question
I have a 2011 F-150 EB, it has the backup camera & alarm. I seem to remember when I first got the truck, that the alarm would not sound when a trailer (with working light system) was connected (factory tow/light package). I connected a trailer that had questionable lights & it blew a few fuses, I got that fixed & the trailer light output works again, but the backup alarm alerts now, even when a working trailer/light system is attached. I took it back to the dealership, but they tell me this is how it is supposed to work: alarm sounds in reverse anytime a trailer is connected, regardless of the working lights or not.
With as smart as the computer system is, it would be a simple thing to detect the trailer circuit & turn off the alarm, so I disagree with the dealer - anyone have experience or knowledge on this?? I can't stand the alarm sounding when I am focused on backing a trailer...

On my 2010, the backup alarm does disable when a trailer is plugged into the 7 pin. Worst case you can hit the reset button and turn off the back up sensors when hooking to a trailer, then turn it back on later.

Find another dealer?
Maybe first check another trailer to be sure it isn't something still funny with yours?

I bet there is one more blown fuse.

Thanks for the feedback - my primary question was RE whether the alarm goes off when the 7 pin connector is used, thanks. I have convinced the dealer that it is supposed to turn off, they have asked me to bring them my trailer if needed...
On another note: where in the world is this "alarm reset button" or whatever it is called?? I have never seen such...

The trailer has to have properly functioning electric brakes for the truck to recognize it. Plugging into the 7-way, in and of itself, does not make the truck see the trailer. There has to be proper impedance in the brake circuit.
