Parking Assist Sensor Sound Change

[NTXTremor]

I went on a short trip, and left my truck at the airport. When I was parking at the terminal, the normal pre-collision or parking sensor sounds went off as I pulled into the spot.

When I was pulling into my garage when I came home a few days later, the warning went off again, as it always does, but the SOUND was different. It was a higher pitched beeping.

Did something change through a software upgrade? Has anyone else noticed a change in the sound?

I can post a video if necessary.

The sound changes when your battery gets a bit low, given your explanation, could be the case here, take it for a nice long drive

Thanks! I would have never guessed that could have been the culprit. I guess I could check the manual. ?

This happens on occasion and in my case, the battery's fine...it's a Ford glitch...once in a while, it wants to sound like a toy truck...

And the battery.
They don't last all that many years on average, although there are some here that have had real good service out of theirs.

I had that sound when my battery was getting ready to depart. Once replaced it went away. Also noticed that I couldn't unlock the vehicle from the rear doors when the battery was getting low. That also cured itself with a new battery.

Mine does this on occasion too. It's a higher pitched sound like someone squeezing the neck of a chicken and it's gasping for air! ?

YES! That is the sound, but what you do to your chicken in your truck is none of my business, Dave. ?

OMG...no Dave!

Yes super annoying sound

Less amps to run it through the dinger box than the sound system like normal

On my 88 Tbird it was easy to just cut the wire...no dinger at all for anything! yay

can the sounds be elimated on reversed, or muffled? I did this on another vehicle I have. I used some foam on the buzzer/speaker thing and worked out well. Still hear it, but the high pitch tone was reduced significantly. I guess I could try to locate where the buzzer is and do the same.

I think that the answer about the battery must be correct. I drove it again tonight, and the sound was back to normal. My truck is just over 3 years old, so the battery could easily be on the way out.

Thanks, everyone.

The T/Shoot for this is lacking, but you have 2 Chime (Sound) sources
1. The IPC (has a small speaker) on it - It is primarily for the (Turn Signal) Click
2. The Sync System uses the (Front) Speakers as Primary for all other Chime Tones

However, what the manuals fail to mention (as I THINK) what happens if the SYNC System has an issue (Low Voltage) - (System Off - To Save Battery) Etc
All chimes will default to the IPC Speaker - and its sounds distorted, or it attempts to produce the sound through the Front Speakers (Center) being primary for the B&O System and due to the Voltage Issue (Its Distorted) or (Amped) Up Incorrectly

I have not experienced this (YET) but when it does happen, I intend to pay attention to where the sound comes from.

Either Way - The IPC is the Controlling Module - For where it places the Sourced Sound - IPC or Audio System

It seemed like the unusual chime sound was coming from the main dash cluster or driver's speaker and not the B&O center speaker.

Front of the shifter on console, the center button, lower row...cancels warning audio...
