Disable reverse / backup dump truck beeping sound using 'free' PACM method / FORScan

[Ride_the_lightning]

It may be called a "safety feature", but I do not agree that it is effective and is anything other than super annoying. Nobody can prove a backup beeper on a MME is needed or improves safety. Mine is turned down to zero, and I have yet to find a reason to turn it back up.

This is doubly true for the horrible fake noise when the car is in Drive. Whenever I walk through a parking lot, when cars approach me I cannot hear their ICE unless it is a big ass truck. I really only hear their tires on the pavement until they pass me, and then I can hear their engine. But they have already passed by.

Why does my MME need to make more noise than the typical ICE vehicle? Answer: it doesn't. In fact, when mine passes you, you still only hear the tires on the pavement. It is beautiful.

Agree. My wife’s Audi is even worse. Sounds like a space ship and I can hear her coming from 1/4 mile away. I can’t even hear my neighbors V8 armada. Why did the government mandate that EVs be more annoying than other cars?

Because the government is run by a bunch of power hungry idiots who think they are smarter than us. They like to tell us what to do, and so many people just shrug their shoulders and go along, making excuses for their idiocy. Not me.

Now I need to stop before this thread gets locked because I cannot control my distain for what the government does to us.

My car is awesome and is a direct result of capitalism. Ford could have produced a compliance car, meeting government mandates. Instead, they built a car I wanted to buy, one that is leading the market (after Tesla, of course). Ford is going to make a crap ton of money because they actually made something desirable. That is how it should work.

I’ll just place This here and direct you to 5.1.2 for some recreational reading. IANAL and this should not be construed as legal advice or relied upon in any way. I did stay in a Courtyard by Marriott once. ?

So you agree that backup beeping isn't in the law at all. You could have just said "i agree"

right
backup beepers may be a requirement for mfg to install, but Owners are not legally mandated to use them. sorta like airbags.... have to be installed by mfg. but can be turned off by drivers for various reasons. but not seatbelt use, which IS required in most states.

Backup beepers aren't mandated for passenger vehicles in the US, not sure about other countries. There's minimum sound levels that are quieter than a conversation -- as in really quiet. Instead of meeting those requirements, some manufacturers have gone crazy with what they're doing. SPL is a logarithmic scale. Going from 40 to 50db for instance isn't a 25% increase in sound, it's a 10 fold increase. To the human ear it sounds around twice as loud. Instead of meeting requirements, they're exceeding them by orders of magnitude. The beeping itself isn't a requirement at all however.

I think the beeping was Ford's way of getting around needing a second speaker in the rear. While in the reverse, the dB level behind the car has to be loud enough. Some manufactures only use a front speaker, so in reverse they have to crank up the volume so it's loud enough behind the car to meet regulations (Toyota is horrible about this). Ford originally had a second speaker in the rear of the car on Job 1 vehicles, but it was never used. I think by adding the "Dink...Dink...Dink" sound to the front speaker it may have made the sound loud enough to hit the threshold behind the vehicle so that only one front speaker would be required on the Mach-E. It's sort of an elegant solution even if it annoys some people.

BTW, I'd much rather hear the "Dink...Dink" in the morning than the ungodly Toyota "angel warp" sound.

There's nothing elegant about it. It's obnoxious. It's also the exact same everything that's in the F150 -- including the fix.

My car has a speaker in the back.... I found it when installing my tow hitch. It was hiding inside a foam protector, which was coming unglued from the diaper....

Probably no sound comes out of it. My car doesn't even have the bracket, and it is a Job 2 2021.

Looks like it had a lead, was it plugged into anything?

I didn't trace speaker wire back, I just re-installed and pinned up the diaper after installing hitch

This is why Ford doesn’t listen to us. Going back and forth over a safety feature. We can’t agree over safety. Why the hell would they listen to us over other minor issues. People just love to bitch over such minor things.

The fake noises are not safer. They are noise pollution.

Perhaps you and I have a different understanding of the English language:

For vehicles capable of rearward self-propulsion, whenever the vehicle's gear selector is in the Reverse position, the vehicle must emit a sound…

Surprisingly, the law seems fairly clear and straightforward in this case.

What about BWC?

				Backup Warning Chime (BWC) • Driver Beltminder (DB) • Pass BeltMinder (PBM) • Mid Pass Beltminder (MPB)
720-01-01	xxxx	xx*x	xx--	0 =	BWC disabled • DB disabled • PBM disabled • MPB disabled		8 =	BWC enabled • DB disabled • PBM disabled • MPB disabled
				1 =	BWC disabled • DB disabled • PBM disabled • MPB enabled		9 =	BWC enabled • DB disabled • PBM disabled • MPB enabled
2 =	BWC disabled • DB disabled • PBM enabled • MPB disabled		A =	BWC enabled • DB disabled • PBM enabled • MPB disabled
3 =	BWC disabled • DB disabled • PBM enabled • MPB enabled		B =	BWC enabled • DB disabled • PBM enabled • MPB enabled
4 =	BWC disabled • DB enabled • PBM disabled • MPB disabled		C =	BWC enabled • DB enabled • PBM disabled • MPB disabled
5 =	BWC disabled • DB enabled • PBM disabled • MPB enabled		D =	BWC enabled • DB enabled • PBM disabled • MPB enabled
6 =	BWC disabled • DB enabled • PBM enabled • MPB disabled		E =	BWC enabled • DB enabled • PBM enabled • MPB disabled
7 =	BWC disabled • DB enabled • PBM enabled • MPB enabled		F =	BWC enabled • DB enabled • PBM enabled • MPB enabled

BWC enabled will chime inside the vehicle when in reverse. Makes the same 3-tone sound as the seatbelt reminder when you first turn the vehicle on.
