Anyone figured out how to turn off the frunk beeping yet?

[BennyTheBeaver]

I just ordered a low pass filter on Amazon - I am going to try this experiment myself!

Sounds good. Keep us posted.

Unfortunately that totally disables both.

You would think one could install a lowpass filter in front of the speaker, to block out "beeps" while allowing the UFO noise. Anyone tried this?

My bypasses only control Pedestrian sounder speaker noises. Not the frunk as that is an entirely different buzzer.

Yeah this thread is confusing but I am actully talking about the backup sound, which comes from the pedestrian speaker. The issue is, that one speaker does two things... the low-speed UFO sound (which is a low frequency) and the backup garbage truck beep (which is a high frequency). The concern is, if you just totally disconnect the speaker, you lose all sound. When really all we want to eliminate is the garbage truck beep. I am going to try installing a low pass filter to see if I can do that.

OK, so I finally got around to working on this this weekend, and it was quite the adventure.

First thing I did was totally remove the speaker. This was harder than I thought it would be based on descriptions here.. it is a tight spot to get a wrench into to remove those two bolts. I eventually got it off though.

The next thing I wanted to do was create a factory-tight connection for the speaker with an extension wire, to give me something I could splice into and play around with without worrying about damaging any factory components. For this I used the tailgate removal plug, which many already mentioned is a perfect fit for this speaker's wire harness. I took a couple of jumper pins I had in my electronics kit and soldered them to wires, then poked them into this harness cable to create a male end... boom, factory good connection. Unfortunately, I do not have the comparable female end to hook into the speaker - so for now I just used two press clips. Does anyone know the name of this type of ford connector, can I order one online???

Next task was to try out this low filter bypass. I hooked it all up, connected it to a 12v power source, set everything in the middle, then turned on the truck - nothing. Then I realized the 12v power source I was using (a battery jump box) seemed to have some kind of "load sensor" and I don't think it was supplying reliable power. I did not have any other 12v battery lying around., so I figured I would connect it to one of my 18v power tool batteries, thinking it would be fine.... BIG MISTAKE, it instantly fried the low flter bypass... so much for that.

However, I was determined to do something in between "no sound at all" and "garbage truck to wake all the neighbours" - then I got to thinking, if this is a regular speaker, then why can't I put in a volume control... so that is exactly what I did. I dug out a 50K variable resistor from my kit and soldered it inline in the wire, set it to 0, and put the truck in reverse - full volume sound. Then I turned it a little up, went back in the truck, tried it again- VOLUME LOWERED - SUCCESS

Last task was to decide where to put it - I figured out a nice little spot inside the top right of the frunk, up by the power lift piston, there is plenty of space there. I mounted my volume control and ran the wires down to the speaker and reinstalled it, and taped up the temporary wire connections. Next weekend when I have more time I will re-route it all the way into the interior drivers side so I can play with it in real time. I am determined to re-visit the low frequency bypass idea at a later date - I may do some more research on what kind we really need to delete just the beeping - or maybe I will just use an Arduino and do it in software - but for now, I have a totally adjustable garbage truck beep.

So I got the speaker removed which takes care of the frunk beep, but is there one for the power tailgate beep when activated by the remote? Does anyone know if is this part of the pedestrian speaker?

This is not part of the pedestrian speaker. There is a speaker in the rear that still has yet to be located if I remember correctly.

I do know there is a Vuvuzela-like device that sits around the top of the spare tire. I've seen pictures from our teardown on @TTT truck (https://www.f150lightningforum.com/forum/threads/lightning-and-identity-theft.12185/), but I cannot share it.

I removed the beeper & tested & the frunk worked fine & no beeper. Put it all back together & now neither the remote or the button will open the frunk. Any ideas?

 

[jerock]

I tried pulling & restting the fuse which did nothing. I ended up manually opening the frunk & it started working after that.

Every time you disconnect the 12 volt battery the frunk has to be closed manually. Stupid Ford. Just force it down slowly and when it gets to the bottom it will suck itself down with the power latch.

I didn’t disconnect the 12 volt battery & after removing the alarm it wouldn’t shut. I closed it manually & it wouldn’t work after that.
I’m not sure what caused it to start working other than manually opening the trunk.

I have a 2023 Lariat with the extended battery and I did get an error on my dash screen after removing this so there must be a code associated with it. Does anyone here who took theirs off have a 2023 model? I don’t know why that would be different from 2022 but I don’t know why I would be the only one getting a message.

see my recent Disabling of the Frunk Beeper by simple removing it's connection: I love it!

Post a pic of the dash error. Could be something else you did.

Ok, so I took the beeper module off again but I believe the error I was getting was from the larger plug that I had to unplug before taking the frunk tub out. When I first tested it yesterday I hadn’t put everything back together and that plug was still unplugged. I’m happy to share that after plugging that back in I now have a silent frunk and no error message!
