It can read sensors and trouble codes from the four major systems, in addition to performing useful functions like real-time battery monitoring, oxygen sensor tests, and more.

We also appreciate that you can record and export data you read on the Launch CRP129E. The automatic health report function is a fast, easy way to get a complete picture of your car’s health at a glance.

Along with diagnostics, the CRP129E also supports essential repair functions. Since you can reset the tire pressure or throttle position in your home garage, that opens up more options for at-home repairs and saves you money at the mechanic.

3. BlueDriver Bluetooth Professional OBD2 Scanner


The BlueDriver system is aimed at everyday car owners and drivers. It can read engine codes from any OBD2-compatible vehicle, which is most of the cars and trucks on the road today. For select manufacturers, it also performs 4-system diagnosis (transmission, ABS, SRS, and engine). This auto scan tool is currently available for select model years of 13 manufacturers. This includes common brands like Ford and Toyota but leaves out some major names, notably Chevrolet and Jeep. If you’re buying BlueDriver for its enhanced codes, double-check its compatibility with your car before you pull the trigger.

You don’t have to be a repair expert to take advantage of BlueDriver. The Repair Reports function gives vehicle-specific suggestions and explains the meaning of trouble codes. Even advanced DIYers can benefit from this extra insight and make faster repairs with BlueDriver.

That makes it the ideal diagnostic tool for home mechanics of all experience levels.

Easy to install and use

4. Foxwell NT624 Elite OBD2 Automotive Scanner


Home mechanics looking for an automotive scanner that won’t break the bank will love the Foxwell NT624. It’s a comprehensive car diagnostic tool that can read codes from all electronic modules. It’s reliable across vehicle models, too, performing just as well on US brands like Chevy and Ford as it does on Japanese vehicles like Nissans, or European brands like BMW.

Home mechanics will also love the quick set-up. You can start using it right out of the box and running scans is easy, no matter your experience level. Updates are easy, too, and you’ll get them free for life, no need for paid subscriptions. It basically pays for itself the first time it spares you a trip to the mechanic, making it a smart investment for everyday car owners.

5. Autel MK808 Professional Diagnostic Testers for Cars


Autel is another top name in diagnostic scanners, and their MaxiCOM MK808 Scan Tool is one of the most affordable options with the full-system diagnosis you’ll find. You can diagnose everything from the emissions to the headlights, and its fast, precise operation means you’ll get that data quickly (and can trust it to be accurate).

The repair functions on the Autel MK808 are relatively comprehensive, as well. While it doesn’t offer advanced coding and programming capabilities, it goes beyond an ordinary scan tool with features like DPF regeneration and BMS reset.

Professionals will also appreciate the design of the Autel MK808. Its sturdy housing is easy to grip and resists damage from drops and impacts, and the intuitive menu layout makes navigation a breeze.



Full system diagnosis
Reset functions including TPMS, DPF, and BMS
Quad-core processor for accurate, fast diagnosis
Compatible with most vehicles from the US and Europe
Easy to navigate 7″ touchscreen
Great value for the included features

6. Launch X431 V+ Professional Automotive Diagnostic Scanner


Professional mechanics who work on vehicles from around the world will get a lot of use out of the Launch X431 V+. It’s compatible with more than 10,000 car makes—and it doesn’t just perform basic OBD2 diagnostics, either. All-system diagnosis and advanced features like key fob programming make it an impressive all-in-one tool for any garage.

For most hobbyists, the Launch X431 V+ is more scan tool than you’ll need. Since it’s designed for professionals, non-experts may find the included instructions a bit confusing at first. Having said that, advanced DIY-ers will appreciate the range of reset functions and will find the tool intuitive to use, with a large built-in memory for storing vehicle information. It also comes with 2 years of free updates and costs about $400/year to update after that, so it has a lower ongoing cost than other professional automotive tools.



Bi-directional communication allows active testing
Supports key programming and ECU coding
Fast diagnosis with Auto-Detect
Wide range of reset and service functions
Compatible with more than 10,000 vehicle models
Optional Heavy Truck add-on
2 years free updates included


Some users have difficulty pairing to wireless OBD2 connector

Verdict: The Launch X431 V+ is the best value you’ll find in professional auto diagnostic tools, offering the same robust diagnostic and programming functions as scanners that cost 4-5 times as much.

7. Autel MS906BT Automotive Diagnostic Tool


For professionals who do need advanced coding capabilities, the Autel MS906BT will meet your needs. It even includes key fob programming and a range of more than 20 other useful repair functions, which empowers you to make a wide range of repairs or even upgrade and tune vehicles.

With “active tests” and OE-level diagnostics, the Autel MS906BT gives you the power to accurately troubleshoot any engine issue. The MaxiFix community is a helpful resource here, too, giving you an easy source for proven repair advice.

Using the AUTEL MS906BT is easy, too, thanks to its wireless capability. This compact and portable diagnostic scanner might not come cheap, but it’s worth the investment for professionals who need broad functionality and vehicle compatibility.



Supports ECU coding and adaptation
Wireless operation with a range of over 150 feet
23+ service functions including IMMO key programming
Full-system diagnosis with bi-directional testing
Knowledgeable online community for extra repair advice

Compact, portable design


Most expensive option on the list

Verdict: The Autel MS906BT supports a wide range of repair and diagnostic functions, including bi-directional testing and key fob programming. Its powerful performance and its easy operation and knowledgeable online community make it worth the higher purchase cost for repair professionals.

8. Launch CRP129X Diagnostic Tool for Cars


The Launch CRP129X is very similar to the CRP129E above. They’re identical when it comes to diagnostic and repair functions. You’ll get the same 4-system scanning, reset procedures, and diagnostic health reports from the CRP129X.

Where the CRP129X exceeds the CRP129E is in its design and performance. It has a built-in Wi-Fi connection that allows you to update the device without connecting it to a computer, and you can do so by clicking a single button. Updates are free for life, too, so you never need to worry about the scanner going out of date.

The design of the interface on the Launch CRP129X is also slightly better. A higher-resolution screen is easier to read even in low light conditions. Also, it includes a keypad navigation option in addition to the touchscreen, letting you use it more easily when your hands are dirty from making repairs



The option of navigating with keypad or touchscreen
4-system diagnosis with full OBD2 mode support
Record and print sensor data
Battery monitoring and voltage test
Includes TPMS reset and throttle adaptation
Compatible with 57+ brands
One-click updates through Wi-Fi are free for life


Doesn’t support full functions for all manufacturers
No coding or adaptation functions

Verdict: The Launch CRP129X adds one-click Wi-Fi updates to the robust functionality of the Launch CRP129E, making it a more convenient option for both home mechanics and professionals.

9. Autel MaxiCOM MK808BT Professional Car Diagnostic Tool

The Autel MaxiCOM is a comprehensive diagnostic tool for an experienced home mechanic. The menu layout is designed for quick access of the most often used diagnostics and features. It can diagnose and reset all dash lights, including the oil, ABS, and SRS systems, so it’s very handy as a troubleshooting tool in a home garage. You’ll also love how affordable the updates are. They’re free the first year, and around $120/year after that.

The vehicle compatibility of the Autel MK808BT is broad but inconsistent. It can communicate with more than 80 vehicle manufacturers but not for all service functions. ABS bleed is one function many mechanics have issue with since it won’t work consistently on common vehicles like Jeep Cherokees (along with other models). This is the main reason it’s not recommended for all professional mechanics, along with the lack of active testing and ECU coding functions. It could work in small garages, but it’s not as feature-rich as the two options above.



Diagnoses all vehicle modules
21 service functions, including IMMO reset and key programming
Option of wireless or hardline connection
Compatible with US, European, and Asian vehicles
Includes 1 year of free software updates
Excellent customer support through data manager


Not all functions available for all vehicles
No ECU coding capabilities

Verdict: The Autel MaxiCOM MK808BT is the best mid-range car diagnostic scanner and is suitable for small garages and advanced hobbyists.

10. Autel Maxisys Elite Professional Auto Diagnostic Tool


The convenience and flexibility of the Autel Maxisys Elite will be worth the investment for professional garages. It’s able to wirelessly communicate with all OBD2-equipped vehicles and performs more tests and service functions than most scanners on the market.

The main complaint from professional mechanics about the Autel Maxisys is with its programming functions. They work great for BMW and Mercedes vehicles but aren’t available for any other models, an issue for garages that work on a variety of cars. Accessing advanced functions also requires a paid subscription after 2 years, and it’s not cheap at $1,200 a year. It’s worth the expense for larger garages but may not be something you can afford in a smaller shop.



ECU programming for BMW and Mercedes
Easy to use touchscreen interface
Built-in Wi-Fi
Wide vehicle compatibility
Efficient diagnosis of complex vehicle issues
Allows performance enhancement and ECU customization
Includes 36+ service functions


Higher price point
$1,200 Autel subscription required to update after first 2 years

Verdict: The Autel Maxisys Elite belongs in a professional garage. It’s capable of diagnosing, servicing, and customizing most vehicles a customer brings in.
