Maintaining modern vehicles requires precision and the right tools, and car diagnostic scanners are indispensable for both car enthusiasts and professional mechanics. At carw.store, our commitment to automotive expertise drives us to provide in-depth, reliable reviews to help you make informed decisions. Led by our experienced lead tester, Jeff Keen, our team invested two weeks rigorously testing 23 diverse automotive OBD2 scanners across 11 different vehicles. This extensive evaluation ensures that our recommendations are grounded in real-world performance and compatibility. Today, we are excited to present our top 10 professional car diagnostic scanner selections, based on these thorough evaluations.
The OBD2 scanners highlighted in this article are designed to work across a wide range of car manufacturers. To cater to diverse needs, we have categorized our top picks: 2 options for beginners, 3 for home mechanics, 3 for professional technicians and workshops, and 2 high-end models with advanced ECU programming capabilities.
Best Professional OBD2 Scanners for Home Mechanics
For home mechanics who demand professional-grade tools, the INNOVA 5610 emerges as our top recommendation. The Autel MK808S and the Launch CRP919E also offer compelling features and performance for those serious about DIY car maintenance.
#1. Innova 5610
Helpful link: Innova vehicle coverage checker
Pros:
- Affordable price point for home mechanics
- Quick and efficient performance during diagnostics
- Lifetime free software updates
Cons:
- Bi-directional control is somewhat limited compared to professional models
- Does not include a printed user manual
The INNOVA 5610 is a professional OBD2 scanner designed with the home mechanic in mind. Its standout feature is bidirectional control, which allows users to perform active tests on engine systems. During our tests, the Innova 5610 reliably executed around 10 active tests for engine functions, such as engaging the cooling fan and adjusting idle speed. The scanner demonstrated consistent and responsive communication with the vehicle, providing immediate feedback to commands.
Continuing the trend of Innova scanners, the 5610 is remarkably fast. It completes full system scans in under a minute, even though scanning all systems takes slightly longer than scanners focused on fewer modules. Live data is accessible in less than 15 seconds. However, the extensive array of data parameters (PIDs) might be overwhelming for less experienced users. It’s worth noting that the INNOVA 5610 lacks built-in explanations for each PID, requiring users to look up definitions independently if needed.
One area where the INNOVA 5610 showed limitations is the ABS Bleeding function. While other special functions like oil reset and battery reset worked effectively across our test vehicles, ABS Bleeding compatibility was limited to approximately 60% of the vehicles tested. This function’s restricted vehicle coverage is a point to consider for users who frequently work with ABS systems.
#2. Autel MK808S
Pros:
- Comprehensive bi-directional control capabilities
- Manufactured by a well-respected and reputable brand, Autel
- Exceptionally fast diagnostic performance
Cons:
- Lacks ECU coding functionality, which is available in some competitors
If you’re seeking a dependable and budget-friendly OBD2 scanner from a trusted brand, the Autel MK808S is an excellent choice. Our testing highlighted several key strengths:
As a product from Autel, a leading brand in automotive diagnostics, the MK808S offers both reliability and user-friendliness. Its responsiveness was particularly impressive during our tests. In a speed comparison against the XTOOL D7 and Launch CRP919E, the Autel MK808S proved to be the fastest overall. Autel has upgraded the internal hardware to enhance efficiency, setting it apart from other scanners in the same price category.
Our testing team also praised the user-friendly interface of the MK808S, reporting a smooth and intuitive user experience.
While the MK808S is a fantastic scanner for many new professional technicians and experienced home mechanics, it does not include ECU coding, a feature found in the XTOOL D7 and CRP919E. However, this trade-off allows Autel to focus on core diagnostic and service functions while maintaining a competitive price point.
Despite the absence of ECU coding, the Autel MK808S excels in essential functions such as full-system diagnostics, active tests, and a wide range of service functions, all delivered with exceptional speed and reliability.
#3. Launch CRP919E Elite
Pros:
- Combines both touchscreen and physical button controls for versatile operation
- Full support for active tests across vehicle systems
- Impressively fast boot-up and diagnostic speeds
- Product from Launch, a respected and reputable brand in diagnostics
Cons:
- Live data graphing is limited to combined graphs, not individual PID graphs
For users who desire ECU coding capabilities, similar to the XTOOL D7, but prefer the assurance of a reputable brand, the Launch CRP919E is a strong contender.
Like the XTOOL D7, the Launch CRP919E delivers on its promise of comprehensive active tests. We were particularly impressed by its speed during testing. It boots up in just 30 seconds and retrieves the VIN in approximately one minute, matching the rapid performance of the Autel MK808S.
A key advantage of the Launch CRP919E is its extensive suite of 31 service functions, surpassing the offerings of both the Autel MK808S and XTOOL D7. It’s important to verify the availability of specific service functions for your vehicle model before purchasing, as coverage can vary.
The primary drawback we identified is in the live data display. While it is fast and updates smoothly, it only displays combined graphs when viewing graphed live data. Unlike the XTOOL D7, the Launch CRP919E does not offer the option to view individual graphs for each PID, which can be preferred for detailed analysis.
However, the Launch CRP919E distinguishes itself with a unique combination of a touchscreen and physical buttons. This design enhances usability in various workshop conditions, especially when users are wearing gloves or have dirty hands.
