Though it is an affordable tool available at $99.95 but while using it you will have to face certain issues like Bluetooth connectivity and proper working of its app as sometimes they may disappoint you.

Moreover it is not compatible with Windows phones, which is very discouraging for a large number of people. Along with it this tool is not suitable for all the OBDII vehicles, as claimed by the manufacturer.

Some of its features do not work with certain vehicles like live data feature do not work with BMWs, Volvos, Hyundais and VW Golf along with Ford Excursion with 7.3 litre Diesel engine.

2. INNOVA 3040J diagnostic scan tool

innova-3040cThis handy car diagnosis tool has been introduced less than a year ago to the market. It can not only read the error codes, like ABS and engine light codes, but also erase them.


It relays 20 types of readings and other information including oxygen, temperature and RPM readings on its 2.8 inch colour screen.

Some other diagnostic tools provided with it also help in diagnosing problem in alternator, battery, malfunctioning of fuel trim and temperature of engine coolant etc.

It can be updated automatically through your Apple computer or Pc via USB. This is an awesome tool for you if you maintain your car yourself. It can store the readings of three cars at a time.

If you want to register some other vehicle on it then you need not delete previous information as it will automatically overwrite it.


Though the price tag of this auto diagnostic tool is just $110 but still you should buy it carefully.

It is not compatible with the vehicles of certain companies including Volkswagen and Innova as well as some of the vehicles used in Canada or US.

3. BAFX Products OBD2 Bluetooth scanner

bafx-productspobd2This car scanning tool is in the list of top best car diagnostic tools because of its extremely affordable price of $21.99 on Amazon.


People using various car diagnostic programs prefer to use it because of its compatibility to almost all the third arty OBDII apps available at PlayStore.

It can scan various issues in your vehicle including reading sensor codes, engine light codes, rest engine light and prepare your vehicle for emission test.

It also works well with various third party applications like torque.

The statistics provided by it like readings of horsepower, RPM, braking info, acceleration along with graph of the speed of the vehicle keep the car geeks occupied for several hours.

The CD provided by its manufacturer allows you to install its reader on your PC.


Though it is a good device still it has certain issues. It is not compatible with Apple devices as well as the vehicles with J1850-PWM protocol. It is also not much reliable as it can stop working anytime.

Another drawback of this tool is that it only reads the stats even only from OBDII system. It does not suggest possible solutions for your problems.

So if your car has other types of sensors then you will have to use some other scanning tool to resolve their problems.

This tool is good only for analysing basic problems of your car containing OBDII system due to its affordable price.

4. Autel MaxiSYS MS906 Wi-Fi Automotive Diagnostic Scanner

Its 32GB memory allows you to save diagnostic information of your vehicle for long. Its built-in battery saves the battery of your vehicle when used to power 8mp rear camera with flash and the entire device. It is used by most professionals due to its efficient GUI.


Like other auto diagnostic tools it also has certain drawbacks like providing backup after long time which is not good in case of emergency or urgency.

It has to face some problem while reprogramming the keys of certain European cars. A bit higher cost is another downside of this tool as Amazon offers it for $1342.

5 Responses to Some of the Top Rated Car Diagnosis Tools In 2022

  1. lam Davies sikombe from Zambia and interested in 2019 diagnostic tool for all cars and kindly advise how I can get it by including the quotation. Waiting to hear from you soon.

  2. The BAFX unit is great diagnosis tool, and can save you a lot of money by not taking it to mechanic. If you’ve got an issue in your car, you don’t have to pay someone a ton of cash to find out what the situation is (and hope that they’re telling the truth because, let’s be honest, there is a bad minority of mechanics out there who aren’t honest). You can also reset the fault code if you’ve got an older vehicle that has a known error and just keeps bringing up a warning light repetitively.

  3. I notice today the diagnostic tools are a lot more sophisticated then only back in mid 90’s, with most tools now able to talk to more systems such as engine, ABS, SRS and Transmission.

    They usually read and clear fault codes and display manufacturer specific code definitions on the screen, display live data stream, freeze frame data, some even offer bi-directional testing and component configurations. Service reset, Electric Parking brake open and close.

    With the latest car diagnostic tools now including features and functions that were only a few years ago available with tools costing many thousands of pounds.

    These tools will allow the user to replace control modules, configure vehicles, calibrate components, adapt new parts to engine such as EGR valves, Air Flow Meters, Diesel particulate filters, and pressure sensors are some.

  4. So I was getting ready to go out and purchase an car diagnosis tool and was wondering who had experience with what.

    I’m kinda leaning towards a Snap-On Scanner with the various cartridges and keys to make it compatible with pretty much anything.

    Any input or experiences. I know there’s plenty of options on Amazon, and all diagnosis tools look like worthy contenders upon reviewing them.
