2010 Reverse Beeping

You can do it with "Dealer type" programming equipment, perhaps even a Scangauge, but the Dealer is the only way for most people.

 

An OBDII programmer is needed. Either the dealer's or one you own. Scangauge II is popular, as is the Torque software running on an Android device connected via Bluetooth to an Elm OBDII to Bluetooth adaptor.

Just for completeness, if you're comfortable with technology it can be disabled with just a OBD2 adapter ($10), and some free software (goSerial for example).

Not saying you should, but it took me some digging when I was in your shoes to discover that I didn't necessary have to buy special software to do this.

 

Buy OBD2 bluetooth scan tool,( i bought mine for 20$) connect it with Android device and download Carista on google play. One you get there open the app, you will see Customizer click on there you will see Reverse beep disable.

Hope that help. I work perfect on my 2011 prius, I can also disable seat belt beep nice person well.

 

I asked my dealership to change the reverse setting when I took the car in for the 5000 mile service. Tech came to see me after he attempted to reset it and explained that the single beep was one long continuous beep. I found that hard to believe, but told him I would rather have the multiple beeps. I came home and did more searching on this site. I am guessing he reset it and tested it while the door was open and that created the long continuous beep. At any rate, after a lot of thought, I bought a ScanGauge II and reset it myself. Not sure that I'll ever use everything that it is capable of, but it was worth the money to me (AutoAnything has them for 20% off through tomorrow) to get running MPG, RPM, code reading, and the ability to get rid of the reverse beeping.
