How to disable Prius back up beep

you have two coolant systems on a hybrid. both systems should of had the coolant changed (due @100k). Spark plugs should of been changed (due @120k). those re the two high mileage maintence items I would be sure were done. Toyota dealer can change the beep to a single beep instead of a constant beeping.

The ABS system is in need of immediate service. The hard pedal is the ABS/Hydraulics malfunctioning and beeping to let you know. Could be a sensor or module maybe a wiring/connection issue but have it serviced ASAP . A bad vacuum supply to the booster or booster diaphragm can also cause a hard pedal and any could light the warning light.

get it serviced, really.

Hi Nina, there are a few different combinations depending on year and model of alarm, for yours could you try disconnecting the battery again, turn the ignition key to accessory.....the one before ignition start and then reconnect the battery. Let me know if it disables the beeps!

First... You should have your passengers wear the seat belts but if you insist you can find the wire going to the seat belt buckle and unplug it under the seat.

you can buy fuse removal tool or use needle nose pliers to remove fuses that what i use..no power locks could bad relay.

Power on the car to IG-ON or READY. IG-ON will do for this purpose.

Using the Trip/ODO button, set the Trip/ODO display to ODO - not Trip A or Trip B

Power off the car.

Now power the car to READY (brake on). This is required so that step 6 works correctly.

Immediately, within 6 seconds of powering on, press and hold the Trip/ODO button for 20 seconds or more. Do not release, just hold it for 20 seconds.

Then WHILE STILL HOLDING ODO button, shift the "gear" selector from Park to R, then press the Park button. Now release the Trip/ODO button.

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.

Press the Trip/ODO button to toggle the mode to the one you want.

Now power the car off to exit the toggle mode.

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.

because the prius is such a nightmare to work on,i would suggest you try to live with the noise or park it where you dont have to reverse.you cannot just bypass the buzzer.......

hi pam from the uk ! the reverse signal/beep can be disconnected however there are different methods of how the beep is operated ? in uk some cars have the reverse light bulbs that are also a beep sounder when reverse engaged ? orthe sounder may be a seperate sounder unit at the rear located either in boot? or behind rear fender? or as you mention beep sounds inside boot area?? the sounder may be hidden behind one of the side panels in boot? if you put ignition on and select reverse then try finding beep location? if/when you find it? just disconnect wirefrom sounder and make sure reverse light/s still remain on tape up the wire disconnected out of way? if it is the bulbs that bleep? you will have to remove and fit an ordinary type bulb usually a flasher/ indicator bulb? hope this is of help and inspires you to diy ? best wishes
