9 Best OBD2 Scanners for 2022: The [Only] Review You Need

The number #1 question I’ve got is: “Tim, what is the best OBD2 scanner you would recommend?” 

That means:

Finding the right scan tool is REALLY hard.

In fact, many people waste a ton of money because of buying the wrong scan tool. 

Many of my clients buy diagnostic tools because they believe in exaggerated advertisements on the internet. However, when they use it, it’s not compatible with their cars or doesn’t meet their expectations. 

They end up disappointed.

This may be the mistake that most people make when buying a scanner.

But don’t worry. 

In this guide, you’ll get a helpful in-depth review of the 9 best OBD2 scan tools from me, an experienced auto mechanic who has used and tested all of them. 

For each scanner, I’ll show:

  • Pros and cons of each product to improve your understanding of them and help you avoid decision-making paralysis.
  • Use cases to help you identify if that scan tool suits your needs or not.
  • How the product performs in real situations to know if it works as advertised.

But first, pick the best suit for you from my recommendations below:

What Makes Me Like BlueDriver?

With a BlueDriver, you can totally fix your vehicle. Thus, instead of paying repairing fees, you can now save a ton of money. 

This is thanks to mode 6, live data, and freeze frame functions. They help you get to the problem’s main culprit by giving you numerous parameters (PIDs). Based on them and together with all the confirmed fixes given, you can become an automotive professional of your own.

bluedriver adapter and bluedriver app
All services on the BlueDriver app include Read Codes, Clear Codes, Saved Reports, Freeze Frame, Smog Check, Mode 6, MIL Status, Vehicle Info, and other Services.

Additionally, you can stay away from being ripped off by arrogant mechanics. More specifically, with the repair report provided by this handy scan tool, you can use it as evidence when going to the repair shops. 

bluedriver repair report
Besides the code definition, BlueDriver also offers code frequency, and possible causes, and frequently report fixes.

What a useful tool for a DIYer!

BlueDriver is also a good option for those who want to test a used car. The reason is that you can easily bring it anywhere and identify error codes deleted by the previous owner. And the code reading function is the way to do it. It helps you read and clear DTCs from main systems, such as engine, transmission, ABS, or airbag. 

What I Dislike?

In terms of its drawbacks, there is something that you should notice. BlueDriver’s live data refresh rate is quite slow, making it difficult to diagnose intermittent issues. So if a perfect live data function is what you want in a scan tool, try Launch CRP123

Second, unlike BAFX, this scan tool does not support third-party apps. Luckily, the BlueDriver app itself works well on iOS and Android.

Note: 

Unplug the BlueDriver adapter after use to avoid car battery drain and abnormal issues.

When pairing Bluetooth, ensure there are no other active devices nearby. Otherwise, your phone cannot connect to BlueDriver.

Vehicle Compatibility 

BlueDriver features can work on any vehicle that supports OBDII protocols. 

However, advanced diagnostics such as reading ABS and airbag codes are not universally compatible.

Therefore, to make sure this device works on your vehicle, check the manufacturer’s website before purchasing. 

Bottom Line

In a nutshell, the drawbacks should not be a big deal compared to its benefits. Or let’s just say, BlueDriver is the best OBD2 scanner for those who have little knowledge but love working on their own vehicles. 

Worth the try!

What Makes Me Like LAUNCH CRP123?

LAUNCH CRP123 is great for reading live data.

You can find that CRP123 comes with a bigger screen than you expect. It can help you view and analyze the live data and data stream more clearly.

launch crp123 screen
Reading data on CRP123 has become easier thanks to the 4-inch TFT LCD color display.

I like that the real-time data provided can be observed or recorded during driving. 

Now you don’t need to watch the screen while you’re driving to diagnose the problem. Just take the car out for a spin and playback the real-time data. Then you have all the information that you need to see to get right to fixing the problem.

More than that, you can use this scanner to diagnose issues in the ABS, SRS, and Transmission systems.

4 main system diagnostics of launch crp123

In fact, a scan tool like LAUNCH CRP123 doesn’t tell you what exactly is wrong with the car. But it will point you where to look and narrow down the possible causes.

Therefore, you can avoid being cheated by mechanics and save money on repairs. In case you are trying to fix the problem yourself, it can help to stop wasting your time on a lot of guessing.

What can you ask for more from a live data scan tool below $150?

Buy LAUNCH CRP123, and it will never disappoint you!

What I Dislike?

Registering is a little tricky. 

You’d better read the User Guide carefully or contact Launch tech support at [email protected] to avoid spending an hour getting your device registered.

Moreover, a hard case cover is not included. If you want to protect your LAUNCH CRP123, you can purchase it separately here.

Vehicle Compatibility

LAUNCH CRP123 is compatible with up to 40 car brands for all mainstream vehicles in the US (from 1996) and Europe (from 2002).

However, not all diesel trucks can be scanned by LAUNCH CRP123. To make sure this scanner works on your car model, it’s better to check the vehicle compatibility before buying.

Bottom Line

LAUNCH CRP123 is the best OBD2 scan tool for you if you’re a DIYer and looking for something more than a basic scanner to pinpoint car issues with real-time data at home.

What Makes Me Like Innova 5210?

Innova 5210 is designed with durable material along with a color display screen. This under $100 scan tool will provide essential functions for a beginner, such as reading/erasing engine or ABS codes, and viewing live data.

Furthermore, you won’t experience a hard start or dead battery because of the charging system test. It helps you check whether your battery and alternator are in good condition or need replacing. 

innova 5210 features
Innova 5210 supports 10 OBD2 Modes and gives users many key features such as
check engine lights, ABS system, battery system, smog status, and view live data.

Innova 5210 will save you a boatload of dollars thanks to its free RepairSolutions2 app. You can use it to troubleshoot Check Engine Light issues. This app recommends you the replacement parts and where to buy them online. There’s no need to search around the Internet just to find the trouble codes’ cause.

innova 5210 repairsolutions2 app
Download RepairSolutions2 on Apple App Store or Google Play for real-time solutions
and fixes your automotive issues.

Once the repair is completed, you are able to use the 5210 to reset the Service Engine light, and the car will operate as normal without dashboard lights. This thing paid for itself in the first usage!

What I Dislike?

Sadly, you have to download the manual online. For this price, I’d expect them to provide a full printed manual in the box instead of having to download it. It’s kind of inconvenient for anyone who wants to read it on paper. 

Also, the cord is quite short compared to many scan tools I’ve used. This three-feet long cable makes me hunch forward to read the screen when plugging it in.

Vehicle Compatibility 

Innova 5210 can be used on any car which has an OBD2 port. But there are some car makes and models that are incompatible with ABS codes. 

Check Innova 5210’s vehicle compatibility to confirm before buying.

Bottom Line

If you are a beginner DIYer or want to identify the problem before visiting a mechanic with a budget under $100, Innova 5210 does the trick. It’s the best OBD-II scanner for you!

What Makes Me Like BAFX?

I gave this BAFX to my brother, Tom – a car lover, on his birthday 5 years ago. He was using my gift with Torque Pro. And since then, when gathering together every Christmas Eve, he always keeps showing off what he could do with this little thing, such as monitoring fuel economy in his car or replacing air filters by himself. Tom and I have to agree that this is the best cheap Bluetooth scanner on the market today.  

Here are some reasons why I and my brother are so into BAFX.

Its main feature is to allow you to read and clear your vehicle’s check engine light (CEL) codes via stable Bluetooth connectivity. What’s more, you can look the error codes up directly on a web browser when confused about them. 

BAFX-OBD2-Bluetooth-scanner
Using Bluetooth 5.0 technology, the OBD2 code reader improves read speeds.

Furthermore, with the check emissions readiness function, BAFX can save you some money on taking over and over the smog test. This helps you by displaying all the emission sensor monitors. If they give you a green “Complete” reading, it means that your vehicle is ready for the test.

bafx bluetooth obd2 scanner smog test

And hey, what I am talking about is the BAFX Android version, but if you have an iPhone but want to use this scanner, the good news is that BAFX does offer a version for iOS devices. And OBD Fusion app is the best option for BAFX iOS with only $4.99 download fee. 

What I Dislike?

Yet, unlike BlueDriver, BAFX does not offer confirmed fixes. So if you want to know how to fix the problems related to DTCs, this is not for you. 

By the way, BAFX does not offer a default app. You can try Piston, Dash Command, etc., but I recommend using Torque Pro. It only costs $4.99 per year. This fee should not be a problem since it works flawlessly on your Android smartphones. 

Also, this device has no “Off” button, so don’t leave it plugged in your vehicle overnight to avoid car battery drain. However, it just depletes a really small amount of power from the battery, so if you forget to unplug the scanner after use, it should not be a big problem.

Vehicle Compatibility 

BAFX scanner is compatible with all consumer gas/diesel-powered cars & light trucks sold in the USA with model years from 1996 and newer.

However, from my research, BAFX doesn’t work on 1997, 7th generation (2003-2007), and 2016 Honda Accords. 

To make sure the device works on your vehicle, email the manufacturer at [email protected] before the purchase.

Bottom Line

“The cheapest is not always the dearest”. With around $20, BAFX is the best car code reader to have in your toolbox. 

Are you a home mechanic who loves fixing car stuff with the lowest budget? BAFX is meant for you!

What Makes Me Like MOTOPOWER MP69033?

Your check engine light sometimes turns on for no particular reason identified on your car. You take the car to the dealer to turn it off, but they charge you $100-$200 to have it diagnosed.

I know that feeling!

And that’s the reason why I strongly recommend you get a MOTOPOWER MP69033 rather than spend money at the dealer.

I really like that this scanner is very easy to use, especially for beginners. You don’t even have to set it up. Just plug it in, and the code reader will turn on automatically.

motopower mp69033 features
Motopower MP69033 offers many features such as read and erase codes, view live data, freeze frame, test EVAP system, on-board monitor, O2 sensor, etc.

Is MOTOPOWER MP69033 an accurate scan tool to rely on?

To see how accurate this scanner is, I’ve tested it on my 2000 Toyota Tacoma.

After getting a trouble code P0137 related to the O2 sensor, I checked the Tacoma again with my $140 Innova 6100P scanner. To my surprise, Innova 6100P showed the exact same error code as the result from MOTOPOWER MP69033.

Therefore, my answer is YES. MOTOPOWER MP69033 is a reliable code reader to identify “check engine” fault codes, find the cause of your car problems, and make the necessary repairs.

Despite its drawbacks, this code reader is well worth the $25 you spend!

Even if you know nothing about car repair, MOTOPOWER MP69033 can help you save trips to the dealer and tons of money for a diagnostic fee every year.

What I Dislike?

As for flaws, the warranty period for this product after registering online is 18 months, not 2 years warranty as per the description from the seller.

Besides, the manual also disappoints you as it seems to be written by a non-native English speaker.

Vehicle Compatibility

MOTOPOWER MP69033 can work on any vehicle with an OBD2 Port.

To be clear: it supports all autos and light trucks sold in the US from 1996 and European from 2000.

This product is advertised to work well on most gas vehicles sold in the USA from 1996 or newer. Diesel vehicle users (Ford F150, F350, etc.) should check the vehicle compatibility before buying by emailing customer support at [email protected].

Bottom Line

MOTOPOWER MP69033 is a must-have for DIYers who need a cheap handheld OBD2 code reader to read and clear engine codes, reset check engine lights, and do minor car repairs at home.

What Makes Me Like Innova 6100P?

Avoiding being ripped off by mechanics is so easy with this under $150 scan tool. 

Innova 6100P can read/erase every code on your car, from basic codes like engine to enhanced codes like transmission, ABS, and SRS. 

Once, other cheap scanners only showed me that my customer’s car had one or more bad ABS sensors. Meanwhile, this one told me it was exactly the left front on his 2003 Ford. Super convenient, right?

But please remember to check if your vehicle is compatible with this feature, or else you can’t read/clear ABS and SRS codes.

Innova 6100P has most of the same functions as Innova 5210, such as battery & alternator test and RepairSolutions2 app. In addition, this scanner can prevent engine parts from being exposed and open to heat damage and corrosion thanks to the oil level monitor.

innova 6100p features
Besides engine codes, Innova 6100P also reads enhanced codes like ABS, airbag,
transmission codes, views live data, tests battery, and monitors oil level.

Innova 6100P is a great scan tool with the ability to show the code’s severity right after the code definition. You can quickly identify whether it is safe to continue driving or if your car needs an immediate fix. 

What I Dislike?

One of the biggest drawbacks of Innova products is most of their products lack a printed manual. But don’t worry, you can download it online. It’s recommended for beginners to read the manual before taking any test.

Besides, Innova 6100P is operated by AAA batteries, but there’s no battery included in the package. I was also disappointed when the scan tool didn’t come with a carrying case. I recommend you should buy this storage box for Innova products to protect your scanner.

Vehicle Compatibility

Innova 6100P can be used on any car which has an OBD2 port. But there are some car makes and models that are incompatible with ABS or SRS codes. Check Innova 6100P’s vehicle compatibility to confirm before buying.

Bottom Line

All in all, Innova 6100P is the best choice of OBDII scan tool if you are a DIYer who wants to identify ABS, SRS, and transmission codes or want to upgrade from a CEL OBD2 code reader!

This scanner can help you read and clear most faults on your car. In case you have a code you’re unsure about, you can look it up directly on a web browser.

LAUNCH CRP129X is also a huge upgrade from your old code reader.

When I tested FOXWELL NT301, I found that its tiny screen with a slow refresh rate didn’t allow me to read the live data stream clearly. But, with the CRP129X, I can pick up any irregularities by analyzing the graphed live display on a large touchscreen.

Launch CRP129X is designed with a 5.0-inch touchscreen.

What Makes Me Like Autel MaxiCOM MK808TS?

Autel MK808TS is an advanced OBD2 scanner with TPMS reset for mechanics or auto DIYers who want to find and solve complex problems in the TPMS system.

autel maxicom mk808ts tpms functions

With the TPMS function, you can:

  • Program TPMS Sensor.
  • Activate TPMS Sensor.
  • Relearn TPMS Sensor.

Please note that Autel MK808TS can activate universal TPMS sensors, and relearn OEM TPMS sensors and Autel MX-Sensors, but only program Autel MX-Sensors. It cannot program sensors from other brands.

If you want to program universal TPMS sensors, you can choose a TPMS tool. Don’t miss my review on Best Universal TPMS Tools.

After using the TPMS feature for the first time, I have found it’s worth every penny.

Once, my customer told me he got an error on the Tire Pressure TPMS. I checked his vehicle’s each tire in the TPMS mode and pressed TRIGGER. The sensors immediately responded, and the problem was due to the warming up weather, the pressure of the two tires was too high.

With Autel MK808TS, finding the culprit for TPMS errors is so easy!

Aside from TPMS, MK808TS offers basic and advanced features as a high-end scan tool. 

You can save thousands of dollars by using 28+ special functions for daily tune-ups, such as oil reset, TPMS, brake bleeding, etc. 

autel maxicom mk808ts service functions

For detailed information about its features, check here.

Moreover, it’s extremely simple to dive into every corner of the onboard system with the full-system diagnosis.

What I Dislike?

Despite those prominent features, there are two downsides I have to mention. 

First, you only have a 1-year free update. It will cost over $300 each year to get the latest version. But don’t worry, the original functions will still be available for use without a subscription.

Note:

Only buy a subscription when you need to keep your MK808TS covering newer functions or car models.

Second, it will take time to sign up before using MK808TS because the registration process is a bit complex. The solution for you is to follow the manual’s step-by-step guide written on page 133. There’s no need to ask for help from Tech Support anymore.

Vehicle Compatibility 

Autel MK808TS covers most cars/light trucks sold in the US from 1996 and the EU from 2002. 

But there are some car makes and models that are incompatible with some service functions. Check Autel MK808TS’s vehicle compatibility to confirm before buying. 

Bottom Line

Autel MaxiCOM MK808TS is worth your investment if you are a home mechanic or advanced DIYer who is looking for an OBD2 scanner with full-system diagnostics, and advanced service functions, including TPMS!

What Makes Me Like Thinkdiag?

Car key programming is an essential function that allows you to reprogram keys, program new keys, and adjust the IMMO system to get back on the road. That’s the reason why there are devices produced to serve this feature only.

But if you are an advanced DIY-er looking for a tool with this function and other features of an OBDII scanner too, Thinkdiag is the best option. 

I first used key programming in Thinkdiag when a client of mine lost his car key last year. Thanks to this, I was able to program his new key. All I asked him to do at that time was to show his registration and license to get his PIN back from the car dealership. Then, I inserted the new key of my client and turned it to the “on” position, and left it in this position for around 20 seconds. After that, I turned it off and turned it on right back and waited for another 20 seconds before turning it off again. The whole process was repeated 3 times and done, I got him covered.

Thinkdiag also can detect any abnormal immobilizer status and help me reset it without repairing keys.

Furthermore, with Thinkdiag, you can clear all of the wrong stored codes and then read and diagnose the only remaining codes after a short drive. In addition, the data stream has a selectable data option so you can select what kind of PIDs you want to look at. It also offers a fast live data refresh rate, making it much easier for intermittent issues diagnosis.

Bi-directional control is also another key point when it comes to Thinkdiag reputation. You can totally use bi-directional controls on any modules you enter without unexpected problems.

What I Dislike?

As for its drawbacks, you should notice that after a 1-year free update, you have to pay an annual fee. The manufacturer does mention some kinds of subscription fees on their website, but it is quite confusing, so I’ll clarify it for you based on my experience:

For example, if you own a Jeep Gladiator, you can use Thinkdiag for free within one year. But after that, you have to pay $40 annually just to keep using the scanner on that Gladiator. What’s more, when buying a Jeep Compass, you should be aware that the old Thinkdiag cannot work on your new Jeep. In other words, you need to pay another $40 for another car model, which means that 2 different car models require double fees.

Note: After the subscription expires, only OBD function (the engine system) can be used normally.

It sounds quite annoying, but this is still a useful scanner if you aren’t working on various cars. And $40 per year for a single car doesn’t sound that expensive as, specifically, you only pay around $3 each month and get a bunch of advanced functions. Still, it’s worth the money.

Vehicle Compatibility 

Thinkdiag works well on almost all OBDII vehicles in the world, as stated by the manufacturer.

However, some functions are not universally compatible depending on the specific car make and model.

Bottom Line

Are you an experienced home mechanic and need an affordable full-system OBDII scan tool with an excellent key programming function? Thinkdiag is definitely for you!
