Back up Alarm on a Gen II

[Schmullis]

Does anyone know if it's possible to silence the back up alarm that activates when you engage reverse? That is hugely annoying.

It would be interesting if CoastalETech had some jumpers to fix that.

Any help would be appreciated.

Just had my first service and the dealer changed it to one short beep only when engaged. Service mangager thought he was cute by telling me there would be a half hour labor charge, then told me not to worry as he has pull with the owner...Yeah right.

Since you asked about Gen II, yes it's possible.

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 (there is no indication... just count)
6. WHILE STILL HOLDING ODO *after* the 10 seconds, shift the "gear" selector to R, then press the P button. 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 (front dash area). "b on" is beep on (default), 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..

The 2010 is a Gen III, and is only Dealer Programable!

Welcome to the Board! For future reference--search is a great tool. I discovered PriusChat the day after I brought home my '06, in May of '06, when I was SO irritated by the backup beep that I googled "disable reverse beep Prius." Got me right here.

There used to be lists of hacks, but I can't find 'em now. BUT, the search engine on this site is WAY better than it used to be, and you should be able to look up individual things you might want to do.

ANY MODERATORS HERE? Whatever did happen to the hacks and easter egg lists?

Great advice from KK and Ruf

Much appreciated!
