FIXD™ OBD2 Scanner – Editor’s Pick

When comparing the prices with other professional-grade scan tools, the FIXD™ Professional Bluetooth OBD2 scan tool might seem inexpensive.

However, even with a lower price, this tool is loaded with features that give it a well-deserving pace among the top professional scan tools.

FIXD Professional OBD2 Scanner
4.64.6 / 5
FIXD™ with its features are beyond the capabilities of any ordinary car code reader.

Features and Functions

The FIXD™ OBD2 professional scan tool comes with an application that is compatible with both Android and IOS platforms.

With freeze-frame technology, the Bluetooth adapter gives clear reads from your car to your phone in seconds.

Additionally, this professional scanner can display the data speed and the engine RPMs as well.

A few features of this Professional Automotive Diagnostic Scanner include:

  • Enhanced set of diagnostic, i.e., ABS, Climate Control, Airbag Control, etc.
  • You can customize the live data with the help of data sources.
  • It gives information about the vehicle such as vehicle specifications, recalls, etc.
  • Ensure you pass an emissions test with I/M readiness, O2 sensors, and smog tests.
  • Freeze frame data give you a clear insight of where the problem is occurring.

FIXD Savings


FIXD™ Professional Bluetooth OBD2 Scan Tool is compatible with most OBD2 compliant vehicles.

That being said, Enhanced diagnostics only work with certain makes and models.

If you own a GM, Ford, Chrysler, Toyota, BMW, Nissan, Honda or Volkswagen, this scan tool will be your engine perfect pair.

Features and Functionality

Connectivity and App

As an OBD dongle, the FIXD™ scan tool doesn’t work alone. It pairs with a smartphone or tablet via Bluetooth.

By doing so, the scanner enables you to run diagnostics straight from your mobile device using the FIXD™ app. It’s good that it uses Bluetooth rather than Wi-Fi.

That means you are free to use your Wi-Fi connection for other purposes like looking up code definitions and possible fixes.

However, compared to Wi-Fi, Bluetooth doesn’t offer a strong connection as you move away.

For instance, you can’t use the FIXD™ app when standing 10 meters away from the vehicle.

The app is basically a diagnostic interface that makes it possible to send and receive commands to and from the adapter.

In turn, the adapter uses the commands to communicate with the vehicle’s computer system.

The best part is that the FIXD™ app is compatible with both iOS and Android devices.

You can install it on your most preferred mobile device, provided it doesn’t run a Windows OS.

On the flipside, the scanner’s reliance on a smartphone/tablet means it’s not a standalone device.

If by bad luck your phone or tablet fails it would mean that you won’t be able to run any diagnostics using the FIXD™ scan tool.


This device earns a spot as one of the best car diagnostic tools because of its functionality. For starters, it can pull and erase codes from all the available vehicle systems.

That includes the engine, transmission, ABS, and SRS. Essentially you can use it to reset the Check Engine Light and other warning lights.

This device earns a spot as one of the best car diagnostic tools because of its functionality. For starters, it can pull and erase codes from all the available vehicle systems.

Besides codes, this FIXD™ scanner performs several special functions. They include VIN retrieval, live data, smog tests and mode 6 tests.

It will also display historical codes that have been cleared and even show you maintenance schedules and recalls.

One thing to keep in mind is that just like ABS and SRS diagnoses, the advanced functions of this scanner don’t always work on European vehicles.

Also, the data provided after mode 6 tests (particularly misfire counts) may be a bit hard to understand.

Continuous monitoring

Another reason why the FIXD™ can easily qualify as the best car diagnostic tool is that it’s an adapter.

It’s a small device that you can leave plugged in the vehicle’s OBD2 port.

In doing so it will feed your smartphone or tablet with real-time diagnostic data. That instant data logging helps you catch faults as soon as they occur.

You can set it to show such things as boost pressure, boost air temperature, engine oil temp, atmospheric temperature etc.

Having said that, it would be wise to unplug it every once in a while. Otherwise, the scanner’s connection to your vehicle’s OBD2 port may start to become loose.


  •  Capable of reading and clearing CEL codes.
  • Can also read and clear ABS, Transmission codes, etc.
  • Comes with a freeze frame feature.
  • Checks if the vehicle is ready for smog test as well.
  • Real time cost estimates.
  • 24/7 car health monitoring.
  • Under $100
  • Up to 50% discount available at the official website.


  • Only iOS and Android platforms are supported by this tool
  • Sells out regularly.

FIXD™ Professional Bluetooth OBD2 Scan Tool can quickly detect the car’s fault codes and erase them as well.

It is a handy diagnostic tool for professional users or expert DIYers.

Although its description says it’s a plug-and-play device, be sure to update the software before using it.

best car scanner
Although its description says it’s a plug-and-play device, be sure to update the software before using it.

Otherwise, it won’t support some functions or work on your vehicle to start with.


This device works on OBD2 vehicles, both domestic and foreign. So if your car is a 1996 or newer model chances are you may use the scanner.

Having said that, the vehicle database needs updating. Although the scanner has the ability to automatically identify a vehicle, it doesn’t do that for all cars.

Case in the example is the Suzuki brand. If you run into that problem simply select the “Other” vehicle option.

Features and Functionality


Like most of the previous diagnostic scanners we’ve seen, the MaxiLink ML619 is a full system OBD2 tool.

That means you can do engine, SRS, ABS and transmission checks.

Ultimately, you can use it to read and clear codes on those systems and thus turn their warning lights off.

In case you are wondering, yes it can reset the Check Engine Light. Also, the scanner indicates drive cycle readiness. It basically shows if your vehicle passes emissions.

The one bugging thing about the MaxiLink ML619 is that it is very difficult to update. First, completing the update process takes a lot of time and effort.

Secondly, you can’t update it on a Windows 10 computer, only earlier versions of Windows.

Live data

Perhaps the biggest strength of the MaxiLink ML619 is its data display.

For starters, it can show several parameters, including live PCM data, drive cycle readiness, ABS sensor data and so much more.

  • Works on almost all OBD2 compliant vehicles


  • Too basic and only good for reading codes
  • The painstakingly difficult updating process

But be warned, the manual is far from clear, you may need to have another diagnostics guide with you as you use this OBD2 auto scan tool.

engine diagnostic tool
You can use the Innova 3100j right out of the box.


This car diagnostic tool device is designed to cover OBD2 compliant vehicles; i.e. those manufactured from 1996 or later.

It works on cars (including hybrids), SUVs and light trucks that weigh no more than 8,500 pounds.

But like most other diagnostic scanners, the Innova 3100j doesn’t work on some vehicles, despite them being OBD2 compliant.

Examples are the 2003 Volvo XC90 and 2005 Ford Expedition.

Features and Functionality

Trouble codes

Primarily a code reader, the Innova 3100j can read and clear engine, SRS, ABS and transmission codes on compatible vehicles.

With that capability, you can use it to find out the cause of the Check Engine Light and even reset the light.

It does offer a brief description of the codes. However, the code definitions are poorly written, you will still need to do some online research after pulling a code.

If you want to use Innova’s official website for code meanings and possible fixes you will have to pay a subscription fee of $29.99 per year for one vehicle.

Other functions

In addition to reading and erasing diagnostic trouble codes, this OBD2 auto diagnostic tool can perform oil and battery resets.

While the manufacturer claims that you can do emission tests, that function is mostly just for show.

The 3100j tends to show that every connected car would fail emission tests, including a brand new car.

Freeze frame data

But one function that works almost perfect is the freeze frame data function. The device will show you several engine parameters, such as engine coolant temp and fuel trim.

In case of a malfunction you will know exactly when the fault occurred and the affected sensors.

But you probably won’t like its response speed when giving data. It tends to lag a bit as you navigate through the menus.

You can use the Innova 3100j right out of the box. The car diagnostic tool comes updated and with everything you need, including a user manual.


  • Covers wide array of cars sold in the US
  • Supports full system scan of OBD2 vehicles
  • Can be used to reset the Check Engine Light (MIL)
  • Small and compact for easy portability and storage
  • Fairly affordable compared to other full-system scanners


  • User manual and code definitions are vague
  • Requires paid subscription for you to access Innova’s online diagnostic resources

If all you’re looking for is a device that can help you read and clear codes then the Innova 3100j could easily rank as the best car diagnostic tool for that.

You can use it to reset the MIL easily. And that makes it ideal for the ordinary car owner.

Advanced diagnostics

This is where the NT510 comes to its own.

It supports such special functions as ABS module activation, brake deactivation, battery registration, TPMS function, oil light service reset, throttle body adjustment and a series of other professional-level functions.

The only issue here is the menu. It’s not quite difficult to navigate, but it could use an easier “escape” function.

As it is you have to go back the same way you came if you want to exit a function. There’s no single “exit” button.


  • Covers all BMW, Rolls-Royce and Mini cars
  • Can support 4 more car brands
  • Functionality includes both basic and advanced functions
  • Solidly constructed with a rugged body
  • Has a multilingual menu

Buying Guide For The Best Profesional Automotive Diagnostic Scanner

Buying an OBD scan tool isn’t as complicated as you may think.

Most of them are actually plug-and-play devices that don’t require complex installation procedures.

Even so, there are several things to keep in mind as you go shopping for your OBD scanner. They include:

Type of Vehicle diagnostic tool

Every OBD scanner falls into one of two main categories, namely diagnostic scan tools and adapters. Diagnostic scan tools are the traditional scanners.

They are stand-alone devices that connect to the OBD port using an OBD connector.

On the other hand, adapters are diagnostic dongles that work with a mobile device.

The dongle plugs to the OBD port and then transmits diagnostic data to a smartphone or tablet via Wi-Fi or Bluetooth.

You need to install a diagnostic app before using an OBD dongle.

Adapters are usually small and can be left plugged in. It makes more sense to buy one of these if you want a device that can do real-time vehicle monitoring.

But most of them are not as durable as traditional scan tools. Plus some apps require paid subscriptions to use.

Diagnostic scan tools are a lot simpler to use than dongles. They feature a straightforward menu. However, they are more expensive compared to dongles.

So, ultimately your choice here not only depends on your budget but also if you’re comfortable using one over the other.

Vehicle compatibility

This is undoubtedly the most important consideration. Make sure the scanner you pick actually works on your vehicle.

Manufacturers usually list all the vehicle makes and models that are covered by a particular scanner. Be sure to check that out on their website or from customer reviews.

You may want to know that while some scan tools are designed to cover just one or two vehicle brands, others are universal and work with a wide variety of cars.

For example, while the Foxwell NT510 covers BMW, Rolls-Royce & Mini, the Ancel AD410 works on all OBD2 cars.

Also noteworthy is that there are scan tools for OBD2 cars, others for OBD1 cars and still some that cover both OBD1 and OBD2 vehicles.

So before settling on one make sure it covers the type, make and model of your car.

Auto Diagnostic Functional features

At the very least a diagnostic scan tool will display engine error codes.

You’re guaranteed to read (and clear) codes related to the Check Engine Light, as well as run emission tests even with the most basic device.

However, some more complex scanners allow you to get more detailed diagnostic information.

You can do such tests as BMS, EPB, oil reset, SRS, DPF, TPMS etc. Others support programming, relearning and actuation.

Before making the purchase you may want to list down all the must-have features. That way you will know exactly what you want your device to be able to do.


Unless you are buying a diagnostic scan tool for a professional auto shop, most of these devices will not cost you an arm and a leg.

They typically cost anywhere from $50 to thousands of dollars. It all depends on the features that it brings to the table.

With that said, make sure the one you settle for is within your budget. It may sound obvious but you can’t purchase something that you don’t have the money for.


A diagnostic scan tool won’t help you in any way if you can’t figure out how to use it. Virtually all of them come with a user manual to help you find your way around the menus.

That said, start by reading customer reviews to ensure that it doesn’t have complicated menus. And that the accompanying user manual can actually help.


Not all OBD scanners are created equal. Some brands are known for their high-quality functionality and durability. Conversely, others are popular for all the wrong reasons.

With that in mind, you may be able to tell whether your device is good or not just by looking at the brand.

Some of the best car diagnostic tool include Innova, Autel, Launch Tech, Foxwell, Actron, FIXD™,  and Ancel.
