I bought this scanner so that I could disable the backup beeper in my 2013 Toyota Prius V. The device worked like a charm, in conjunction with the Torque app that I downloaded to my HTC One M8 Android phone. It's not particularly intuitive and it took me about an hour before I realized that I had to go to Menu/Manage extra PIDs/Sensors and manually import the PID for disabling the backup beep. The Priuschat forum was helpful in supplying the info that eventually got me to an Excel spreadsheet that had all of the codes for my vehicle. Here is the link for both US and metric:

Here are the instructions for how to do it:
"This topic has been covered many times but I'll save you the trouble to look it up. Dealers should do if for free. If your dealer will not then find another dealer (talk to the service rep as your salesman might not know anything about it). Some have had it done at purchase with most waiting for the first 5000 mile checkup. They'll usually say they'll do it once for free then charge afterwards. Though some will try to charge even for that first time.
Another solution is to use a Scangauge II (which is about $160 currently on amazon) but it's has a small screen and limited interface and confusing commands (if you're new to it). The advantage is that it's a self contained unit and connects directly to the OBDII port on your car and has a reputation of being very reliable.
If you'll check the other parts of this forum you'll see threads dealing with bluetooth OBDII scanners that you control with a PC, tablet or smartphone. There are a lot of different compatible devices with some of the better one's hovering around $90-100, or you could get one of the knock-offs for about $20. I bought a highly reviewed unit off amazon for about $23 and it works brilliantly. I interface with it through my Android phone using the Torque app that I paid about $5 for. The advantage of this is that it's wireless, and you have very nice visual interfaces of lots and lots of data coming from your vehicle.
This thread in particular: GenIII Prius Custom PIDs for Torque app | PriusChat has ton's of custom PID's to use in the Torque application - basically means they made custom commands that can give you easy access to a ton of information and some commands to change things like the reverse beep.
All you need to do is connect the Bluetooth scanner to the OBDII port that is fully exposed and just below the steering wheel - takes just a few seconds.
Then download the Torque app (if you have an android device - iphone doesn't do as much as the android) to your phone and install it.
Download the zip file in the link above with the PID's. You want to unzip it and move the files to your .torque/extendedpids folder within your android device. If you use an app like ES File Explorer you it can view, move and even unzip the file.
Turn on your engine, and turn on the bluetooth on your phone. You can connect from within the app, but I prefer to use the phone's bluetooth settings. The device should show up, and you can try to pair to it. My device's password was "1234" use whatever was in your instructions.
Now on your phone start the Torque app (should already be connected to the scanner), hit menu and set up the vehicle profile. (before you do that you can go into settings>Units and adjust the unit to your region so that the next step makes more sense)
These were recommended:
Engine Displacement: 1.8
Weight:3275 US lbs
Fuel: Petrol
Fuel tank: 11.9 USG
Max RPM: 5200
Volumetric Efficiency: can't find this information, though it's supposedly a calculation of the volume of actual air being pumped vs theoretical - I just left it at the recommended 85 but others put in different numbers.
Remember to save everything.
Under menu>"settings">"Manage extra PIDs/Sensors" screen hit your menu button again then >"add predefined set" you should see a list of vehicles and the profiles you had just unzipped to your device. Choose "GenIII Prius 4-24-12 (US)" or if you like there is another option for (metric)
Then the screen will show a list of a ton of custom PIDs. Most of these are commands to access information that you can set up as a gauge to view in the Realtime Information desktop view.
But there are a few commands that you can send to the car one time (through a test function of the Torque app) to adjust settings like the reverse beep:
Scroll down all the way to the bottom. You'll see a PID for "Reverse Beep Disable". Choose it then from the pop up choose >edit. From there just scroll down all the way down and you'll see a button called Test. After clicking the test button a status/confirmation popup will show. After that is done the reverse beep is now disabled. Try to put your car into reverse to confirm. You can also adjust a few other things, like seatbelt alarms. Scroll through list to see them all. To just send the command one time, you need to do a test.
Most of the other PID's are to check realtime status of the engine. You can also check error codes and reset them. Great device to have and I much prefer being able to set alarms and beeps myself."
