The OBD2Scanz V4 Bluetooth is our OBD2 Bluetooth scan tool that has been created to offer you the best experience and ease of use to get the data you want from your car and check and clear your engine check light. With a high quality micro-chip manufactured in the USA (not a cheap clone), Multi protocols and small size it is the perfect OBD2 scan tool to view all the engine data that your car can supply.

The OBD2Scanz Bluetooth OBD2 scan tool (Car Scanner) works by being plugged into your OBD2 port and reading data from a number of sensors on your car. You will find this port within 50cm of your steering wheel (Check below steering wheel and above pedals, can be behind plastic cover) and it is easy to access. Check our post here on how to find it. This data is then displayed on your phone or tablet using a free OBD scan tool app that you download from the play or app store. You can also scan the QR code on the back of the packaging and it will take you to our website install page that shows you what and how to install the app. There are a large number of these ranging from free to ten dollars and you can check them out here.

You can check what fault codes cause that check engine light and what they mean when they happen on your car with this OBD2 Scan Tool.

You can also use this tool to make custom dashboards* with live data that will display on your phone or tablet while you are driving. So you can view things like coolant temperature, air intake temperature, boost, and several others. Or make up a custom trip computer with all the gauges you need.

Please note this tool can check only engine/general faults and if you want to access other modules on your vehicle like ABS or Airbags, etc., you will need a full system scan tool. Please view these here.

You can find out why the annoying check engine light keeps coming on and fix this problem and clear this check engine light. Saving you from having to go to the mechanic and paying money for them just to tell you that there was dust around your fuel flap door and this was causing your car to think that it was open (an all too common problem).

Will it work with my car?

If your car is 2002 or newer, then yes! It is full OBD2, and it will work with your car. If your car is older, then please contact us.

How do I install it and get it to work?

All cars have a diagnostics port (OBD) and if your car is OBD2 it has to be within reaching distance of the steering wheel. Look under the steering wheel and above your pedals, and you will find it. Then all you have to do is plug it in and download the app on your phone. Check out the video above.

Can I leave it plugged in?

Yes, you can leave this OBD2 Bluetooth device plugged in as it has small power usage when in sleep mode. However, if you are parking your car up for a month or more, we suggest you take it out.

Will it clear my engine’s fault and tell me what’s wrong?

Yes, it will do both since it is an OBD2 Bluetooth scan tool. In the app, you just click on check engine faults. It will then come up with code like this P0171—Oxygen Sensor. So you know the problem is with the oxygen sensor and then the best thing to do is google the code and your car’s year and model. e.g. Toyota Hilux 2017 P0171. Nine times out of ten this will be a common problem and the answer will be the first thing that pops up.

Do I need an internet connection for this?

The only time you need an internet connection is when you are downloading the app after that you do not need it. So when you are out in the outback with no coverage, yes it will still work and allow you to check/clear faults and access your engine’s data. As it connects to your phone via Bluetooth being an OBD2 Bluetooth scan tool, and you already have downloaded the app.

Can I use it on multiple cars and with different apps?

Of course, you can just unplug it and plug it into any car you like. Takes all of 2 seconds. And yes, you can use multiple apps and on multiple devices. Just download the apps that best suit your needs. You can see a list of a few below and what they do. Please contact us first to confirm if this scanner is fully compatible with your preferred app that is not on our list.

Does this show the transmission temperature?

Yes, it can read transmission temperatures, but it’s not enabled by default. You will need to program the app it works with to read that parameter. The programming is called ‘PID codes’, and you can usually find these through an online search (the codes also vary depending on vehicle make and model). Because of the many variable PIDs available for transmission temperature, OBD2 Scanz does not provide these PIDs.

Use Cases

  1. A great tool that saved me $ and a trip to the shop. I was unsure what the check engine light meant. Plugged in the OBD2-Scanz scan tool, and it told me low voltage on the MAF sensor. So I replaced this part, cleared the check light, and all is good in the end.
  2. Handy to have as was out in the middle of nowhere and the check engine light came on and put the vehicle into limp mode. Check what the fault code was and helped me sort out the issue and then clear the fault code to get out of limp mode and carry on my trip.
  3. Always have this on with extra gauges showing, so I can keep an eye on things like oil temp and trans temp when towing on long journeys and in hot places as want to pick up any issues before they happen.
