Automotive Diagnostic Tools Buying Guide
Benefits for DIYers
When the warning lights on your dash are illuminated, they’re responding to trouble codes that your engine’s computer has generated. For the engine, these codes are grouped under a diagnostic protocol known as OBDII. Short for “on-board diagnostics,” the OBD system is standardized across vehicle manufacturers, allowing mechanics to quickly identify and repair engine problems.
The engine isn’t the only system that puts out these trouble codes, either. You can troubleshoot errors in everything from your tire pressure to your airbags with the right code reader. These codes aren’t standardized, however, and can’t be read by all OBDII scan tools.
That’s where a professional scan tool comes into play, giving you access to error codes and other helpful data primary code readers won’t provide. Other benefits of a professional automotive diagnostic scanner are as follows:
Make Repairs Yourself Instead of Paying A Mechanic
Some vehicle issues require professional expertise, but others are simpler and can be easily (and cheaply) repaired at home. With a scan tool, you can identify the problem and its severity, gaining the knowledge you need to make small repairs yourself. Once those repairs are made, an automotive scan tool allows you to clear the error code and turn off the check engine light, too.
Preparing for State Emissions Tests
Much of the information included in OBD2 diagnostics is related to your vehicle’s smog emissions. With a professional automotive scanner, you can identify issues with the emission system before you go to the inspection, saving you both time and money.
Gain Insight Into Engine Health And Performance
Professional car scan tools read a range of parameters and data. Logging this information lets you identify trends and developing issues before they’re a big problem. When you do need to go to the mechanic, you’ll walk in knowing the exact issue you need to have fixed, giving you peace of mind that you’re not being ripped off.
Recommendation for any beginners: Bluedriver
Benefits for Auto Repair Shops
Automotive scanners don’t just read trouble codes and record module data. Professional models also allow you to interact with the engine, making necessary repairs and adjustments. If you’re a professional mechanic, there are a few key features you’ll need in a diagnostic tool:
- More services to offer to your customers. A scanner with coding and programming capability allows you to go beyond necessary repairs. You can add services like making new key fobs or tuning the engine, things your customers would otherwise have needed to have done at a dealership.
- Expanded vehicle coverage can grow your customer base. Professional scan tools can diagnose and repair vehicles from dozens of manufacturers. The more cars and trucks you’re able to work on, the more potential customers you have nearby.
- Improve speed and efficiency. We all know time is money. Speed can be especially important in automotive repair, where customers are eager to get back on the road. Along with high processing speeds that scan trouble codes, many professional tools have intelligent features that automatically gather information from the engine. The inclusion of bi-directional control is another big time-saver, identifying failing valves or solenoids so you can get the right to repairs.
- Better accuracy. A diagnostic tool is useless if you can’t trust the information it gives you. Industry experts have vetted professional tools from trusted brands so you can count on the accuracy of their readings.
Recommendation for Auto Diagnostic Specialists/big shops: Launch X431 V+

Types of OBD2 Automobile Diagnostic Scanner
Not all code readers are created equal—and it’s not just a matter of which brand makes them. Different models are suitable for specific users, so you want to make sure you get the right one for your needs. While there are a lot of different styles of automotive scanner out there, the ones you’re most likely to come across include:
Auto Scan Tools for DIY
This is the type of scanning tool that most DIYers want. It goes beyond a code reader, providing multi-system diagnosis and some service functions, but it is more affordable than OE-level diagnostic tools meant for professional garages. Bluedriver and Foxwell NT624 Elite are excellent choices in this group.
Professional Car Diagnostic Tools
Service functions, coding, and programming capabilities are the main advantages of professional diagnostic tools. You can tune, remap, and otherwise customize the ECU and perform tens of service and diagnostic functions. They’re more expensive and, therefore, what they can do is excellent. However, this type of diagnostic tool ONLY suits professionals working in auto repair shops. If you are a professional automotive technician or diagnostic specialist and ECU programming is not your priority, think about the Launch X431 V+. But if you regularly program ECU of BMW or Mercedes Benz vehicles with J2534, consider taking the Autel Maxisys Elite.
How Much Should I Pay?
DIY-ers should expect to spend somewhere around $100 – $1,000 for a high-quality diagnostic scanner. Models in this price range typically include full-system diagnosis and service functions such as Oil Reset, ABS Bleeding, Injector Coding, EPB Reset, BMS Service, SAS Calibration, DPF Regeneration, etc. The features they omit also tend to be what hobbyists and home mechanics won’t use anyway, things like ECU coding requiring more advanced knowledge to do successfully. A typical choice for you, if you want to have such a scan tool around $500, is the Autel MK808BT. The Budget Buy is the Bluedriver, only about $100. Somewhere in the middle is the FOXWELL NT624 Elite, which costs you around $250.
A professional automotive technician or diagnostic specialist is most likely looking at a budget from $1,000+ to $3,000+. Expect to be on the higher end of that spectrum if you need more sophisticated service functions or complicated performances like car key coding, programming, or ECU mapping. With a budget of around $1,000 to $1,200, you can buy a professional car diagnostic tool like Launch X431 V+, my favorite choice ever. It can do almost everything in your shop, from Oil Reset to ABS bleeding, from bidirectional control to key programming, or ECU coding.
Compatibility and Vehicle Coverage
The OBD2 code system is universal on all vehicles made in 1996 and later. Most professional car diagnostic scanners have broad compatibility for essential diagnostic functions, but the same may not be true of the service functions, “active tests,” or multi-system diagnostic abilities.
With BlueDriver, for example, you can read necessary information from any vehicle with an OBD2 port. It can also read and clear Enhanced Codes for ABS, SRS, and transmissions systems, but not all cars. Those services are only available for select brands and vehicle model years.
The same is true of more advanced professional scanners. The Autel Maxisys Elite is compatible with more than 10,000 models, but not all service functions will be available for all of them. The most limited is the J2534 ECU programming, which can only be done on two manufacturers BMW and Mercedes.
The bottom line is that you should pay close attention to which features are offered for vehicles when you’re shopping for diagnostic tools.
Automotive diagnostic tools don’t just read trouble codes and record module data. Professional models also allow you to interact with the engine, making necessary repairs and adjustments. If you’re a professional mechanic, there are many crucial features you’ll need in an advanced auto diagnostic tool:
Full OBD2 Diagnostic Functions
The OBD2 diagnostics consists of ten modes. These include reading and clearing codes, retrieving live and freeze frame data, and conducting emissions tests. Many cheap code readers will only give you access to half of these modes or less. For the most accurate diagnosis, DIYers will want to get a scanner with full OBD2 functionality like the Bluedriver.Check Price at Amazon
All System Diagnosis
Scanners that can read trouble codes from all the electronic modules in a vehicle are ideal for advanced DIYers and necessary for professionals. The OBDII system doesn’t catch all engine problems. In a professional garage, you need a scanner that can read all electronic modules, giving you a complete picture of the engine’s health. You’ll find many scanners in the price range from $200 to $300, like the FOXWELL NT624 Elite that not only lets you diagnose all systems but also perform several service functions like Oil Reset or EPB services. The average price goes up if you also want to get information from other electronic modules like climate control.
Reset and Service Functions
The term “service functions” is a catch-all for a range of repair functions included in auto scanning tools. One of the most common is oil reset, allowing you to turn off the oil light on your dash and reset the parameters after an oil change. Other essential functions include DPF regeneration, ABS bleeding, TPMS reset, adjustments to the throttle or suspension, etc. Generally speaking, reset and service functions will be more important from a professional standpoint than they are to DIY-ers, though they can be helpful in home garages, as well. You will find the essential service functions (26 ones) in the Autel MK808BT, a perfect pick for you if you’re an experienced home mechanic.
Active Tests/Bidirectional Control
Also called “active testing,” bidirectional control allows the mechanic to activate or test mechanical components on demand. This process tells you if individual actuators, valves, and pumps function the way they should, allowing for more efficient and effective repairs. If you’re looking to do such tests, buy the Launch X431 V+, one of the best bi-directional scan tools today.
Key/ECU Coding and Programming
Car key/key fob/ECU coding or programming is primarily used to change keys, tuning, and remapping engines to optimize their performance, allowing you to make changes to the engine computer’s parameters and settings. It’s also helpful for making software updates and troubleshooting issues with fuel efficiency or engine power.
What Else Should I Consider Before Buying an OBD2 Scanner?
Functionality and compatibility are the most important considerations when you’re shopping for a scan tool. There are other factors you’ll want to pay attention to as well, however, including:
The most common smart feature on diagnostic scanners is an Auto VIN option that instantly identifies the make and model. While intelligent features can be helpful from an efficiency standpoint, they’re not as crucial to the overall operation as other factors.
This is primarily a concern for professional garages that need to diagnose a lot of vehicles. A higher processing speed allows the scan tool to quickly read and process data, allowing you to promptly respond to the repairs. Look for a scanner with a quad-core processor for the fastest diagnosis.
A diagnostic tool is useless if it’s not giving you the correct information. Accuracy can be difficult to verify, one of the main reasons it’s essential to buy a scan tool from a reputable brand with a reputation for quality.
Some scan tools come with lifetime free updates, while others will require a paid subscription after a certain length of time. Pay attention to how the updates happen, as well. Updates through Wi-Fi directly on the scanner are the most reliable, saving you the need to worry about your operating system’s compatibility.
Troubleshooting problems with a scan tool can be frustrating. A reliable and responsive customer support line avoids this hassle, so you can spend your time fixing cars, not tinkering with the device itself.
Not all vehicle problems are easy to diagnose. A strong community of scan tool users can help you solve tricky repairs and issues and share general knowledge to help you use your scan tool more effectively.
