for Android Phones ONLY - Wireless Bluetooth Diagnostic OBD2 Scanner Car Code Reader and Scan Tool for All 1996 & Newer Vehicles ELM327 Compatible OBDII

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:http://priuschat.com/attachments/geniii-prius-4-24-12-zip.37079/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: 1.8Weight:3275 US lbsFuel: PetrolFuel tank: 11.9 USGMax RPM: 5200Volumetric 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.": http://priuschat.com/threads/turning-off-the-reverse-beep-on-a-2012-prius-v.116512/#ixzz3NQw6W0JbThis device does work for a very reasonable price.

I bought this not knowing if it would detect the manufacturer-specific codes in my 2002 Toyota Prius. First, let me start off by saying, I am not a mechanic. I'm an average person who can follow instructions and prefers DIY repairs if they'll save me hundreds or even thousands of dollars.My Prius has been sitting inoperable for over a year because the hybrid battery is faulty. The 12v auxiliary battery had drained and no electronics would turn on, so I attached a JNC660C Jump-N-Carry (which I purchased for that purpose) and got the power restored to the ECU so I could read the diagnostic code/s. This little guy lit up right away, flashing its lights and retrieving the codes.A flip of the Bluetooth switch on my phone and a quick download of the free version of the Android Torque app later, and I was in business. The Torque app leaves something to be desired, but the BAFX scan tool did its job. It easily connected with my imported AGM Rock V5 phone (using the supplied Bluetooth pairing password) and sent a P3030 code, which is VERY specific to the Prius.It only sent the one code, which surprised me, as I thought there may have been more that was wrong with my car... and perhaps there is, but I cannot start the engine until I fix the hybrid battery. Now I can fix the hybrid battery, knowing what's wrong with it. The unit works in near real time with only a slight delay. I can't be unhappy with its performance, having spent around $23 (I chose the BAFX unit rather than the $11 Soliport model, based on reviews).Next I used this on a 1996 Toyota Rav4 (manual transmission) that was not throwing any engine codes but definitely has some engine problems. Although I was unable to diagnose the engine problem for lack of codes (and lack of skill or experience as a mechanic), the BAFX scanner still sent very useful information to my phone, such as engine load (%), RPM, intake manifold pressure, engine coolant temp, etc. I am confident the information will help me diagnose the mechanical problem/s.The Torque app can be customized according to how you prefer to see your data (individually customizable dials, graphs, and displays). It takes a bit to set up, but I now have it in a configuration that makes the most sense to me (fuel information on one screen, engine information on another, etc.). The unit may be left in while driving to compile data on MPG efficiency (real-time or averaged). You can clear the check engine light with this unit.Finally, I used this on my girlfriend's perfectly healthy 2003 VW New Beetle (automatic transmission). As expected, it did not throw any DTC codes, but it was VERY interesting to see her car's engine load % was only 4-5% at idle, while my Rav4 fluctuated between about 25% to 30%. Maybe there is something to that...As far as switching this unit between platforms (Prius to Rav4 to VW), there was nothing extra I needed to do. All I did was unplug it from one vehicle, plug it into the next vehicle, and wait a few seconds for the unit to make the connection to my phone. That's it! I did not use the CD that came with the unit because I did not intend to use it with my laptop (perhaps I will at a later date--maybe it will give more in-depth information). I will say the link the app provided for the P3030 code for my Prius did not contain any information on the code. I had to separately Google the code, but big deal.Overall, I'm very happy with the unit and might purchase another, perhaps with a cable, where I can move it behind the dash so it is not in the way while I drive.***** UPDATE *****I fixed my Prius, and still use the BAFX to clear the occasional P0420 (catalytic converter) code. I need to get it replaced, but being a hybrid, I'm not damaging much by clearing the code. The BAFX tool allows me to clear the code every time my computer decides to tell me my catalytic converter needs replacing (about once every 3 weeks, the engine light kicks on). I plug this little dude in, switch my bluetooth on (now I'm running a Samsung Galaxy S4), open up the Torque app, and clear the code. Problem solved (well, temporarily, anyway). I recommended this to a friend, who had codes with a Land Rover. He was able to diagnose and clear his codes with my device, so he bought one. I need another now, because I kicked mine accidentally and broke it while trying to take off my parking brake a little too aggressively (woops!). Mine still works, even though the plastic was smashed and broken, and the pins were bent (I bent them back into place using a pen or keys or various other sundries).

This little OBD2 scanner is a great tool for the price. It connects easily to my Android phone via Bluetooth, and the Torque Pro app (which costs a few bucks extra) provides a wealth of information. I can read and clear check engine codes, monitor real-time data like engine temperature and RPM, and even track fuel economy. It's not the most advanced scanner out there, but it's perfect for basic diagnostics and troubleshooting. Four stars! ⭐️⭐️⭐️⭐️
