Disabling reverse beep, installing backup buzzer

<div class='quotetop'>QUOTE(Godiva @ Apr 14 2006, 03:22 PM) [snapback]239893[/snapback]</div>

At the risk of sounding ignorant, What is a backup buzzer/alarm? And how is that different from the reverse beep? I'm wondering if it is a gizmo that starts making noise when you get close to something?

The difference is that the reverse beep can only be heard on the inside, while the buzzer will be heard outside while the Prius is backing up (in order to warn people). JC Whitney has several types, including one that says, "This car is backing up!"

The gizmo you're thinking about is a reverse backup sensor, which again would only be heard on the inside.

 

Godiva,
thanks for the clear and simple directions - and with photos!

 

Is this pdf still available? I'd find it to be of immense help!

 

I new to chat rooms and the like. I am trying to find out how I can get a copy of the PDF with instructions on disabling the reverse beeper. Thanks, alanx3aa

 

How to shut off the beeping

1. Power on the car to IG-ON or READY. IG-ON will do for this purpose.
2. Using the Trip/ODO button, set the Trip/ODO display to ODO (not Trip A or Trip B)
3. Power off the car.
4. Now power the car to READY (brake on). This is required so that step 6 works correctly.
5. Within 6 seconds of powering on, press and hold the Trip/ODO button for 10 seconds or more.
6. WHILE STILL HOLDING ODO *after* the 10 seconds, shift the "gear" selector from P to R, then back to P. Now release the Trip/ODO button.
7. If the last step was successful, "b on" or "b off" should be displayed in the location where the Trip Odometer or Odometer is normally displayed. "b on" is beep on, and "b off" is beep off.
8. Press Trip/ODO to toggle the mode.
9. Now power the car off to exit the toggle mode.
10. Power the car on to READY and confirm the reverse beep status by shifting to R. The beep should not be audible if "b off" was selected, and should be audible if "b on" was selected

This should work if follow the directions carefully. V.

it is so nice not to have the beeper disturbing the quietness of the cabin. Toyota screwed up by not putting the beeper on the outside. I like the after market one telling people the car is backing up

 

Thanks, Godiva!

I saw other instructions regarding disabling the back-up beep on Priuschat that omitted a couple minor details. Now the cabin is ahhh-so-quiet.

 

When I first drove away Prius IV 2010 from the dealer, it started beeping. I saw something wrong. Right the way, I called the sales rep to check, and ask when the beep is not on the outside. Now I know the Toyota screwed up the designed. Question, I have 7 year bumper-to-bumper warranty from Toyota. If disable peeper and install alarm, would this void the warranty? Thanks,

 

has anyone successfully done this on the G3s yet?

 

Just did this on my wifes 2008. It drove me nuts (only had the car 1 week). It worked great..I'm not gonna tell the wife and see if she notices

 

This works great until you let someone borrow your car or leave it at the oil changer place where they don't know how to read a gearshift knob... I had to re-enable mine because I forgot that "others" use my car as well.

 

This does not work on my Prius 2010.

 

I know this is a Gen 2 thread, but the search keeps bringing me here for this Reverse warning beeping. Any chance someone knows the steps for the Gen 3?

 

I do. Take it to the dealer, and ask that they disable reverse beep.

Toyota made it require ODB-II hardware. If you have an ODB-II device like the scangauge II, you can use that.

 

Good to know - Thank you!:thumb:
