Best Professional OBD2 Scanners for Home Mechanics
For DIY enthusiasts and home mechanics looking for a balance of features and affordability, the following three OBD2 scanners stood out in our testing: the INNOVA 5610, the Autel MK808S, and the Launch CRP919E.
#1. Innova 5610
Helpful link: Innova vehicle coverage checker
Pros:
- Excellent value for money
- Fast and efficient performance
- Free lifetime updates
Cons:
- Bi-directional controls are somewhat limited
- No printed manual included
The INNOVA 5610 is a standout professional OBD2 scanner designed for the home mechanic who wants more than just basic code reading. Its key feature is bi-directional control, enabling users to perform active tests on vehicle systems, particularly the engine. During our tests, the Innova 5610 reliably executed around 10 engine system tests, such as fan control and volume adjustment, demonstrating consistent and responsive communication with the test vehicles. The scanner reacted promptly to commands, providing a smooth user experience.
Performance-wise, the INNOVA 5610 is impressively quick. It scans all vehicle systems in under a minute and displays live data in less than 15 seconds, comparable to the speed of the INNOVA 5210. While the wealth of data parameters (PIDs) might be slightly overwhelming for novice users, the speed and breadth of information are valuable for diagnostics. However, it’s worth noting that the INNOVA 5610 does not provide built-in explanations for each PID, requiring users to potentially look up definitions independently.
One area where the INNOVA 5610 showed limitations is its ABS Bleeding function. While functions like Oil Reset and Battery Reset performed well across our test vehicles, ABS Bleeding compatibility was around 60%, which could be a constraint for some users depending on their vehicle make and model.
#2. Autel MK808S
Pros:
- Comprehensive bi-directional control
- From a well-regarded brand
- Very fast and responsive
Cons:
- Lacks ECU coding functionality
For those seeking reliability and brand reputation without breaking the bank, the Autel MK808S is a top recommendation. Autel is a recognized leader in diagnostic tools, and the MK808S lives up to that reputation. One of the standout features identified during our testing was its exceptional responsiveness. In a direct comparison with the XTOOL D7 and Launch CRP919E, the Autel MK808S consistently proved to be the fastest, thanks to hardware upgrades focused on efficiency. This speed advantage sets it apart from competitors in the same price bracket.
Our testing team also praised the user-friendly interface of the Autel MK808S. The navigation and menu system are intuitive, making it easy to operate even for those with less experience.
While the MK808S is an excellent choice for many users, it does not include ECU coding, a feature found in the XTOOL D7 and CRP919E. This trade-off is often associated with choosing a more established brand like Autel. However, despite this omission, the Autel MK808S excels in core diagnostic functions including full-system diagnostics, active tests, and a wide range of service functions, all performing smoothly and effectively.
#3. Launch CRP919E Elite
Pros:
- Combination of touchscreen and physical buttons
- Full active test support
- Impressive speed and responsiveness
- Reputable brand
Cons:
- Cannot display separate graphs for live data
The Launch CRP919E Elite is an excellent option if you desire ECU coding capabilities along with the assurance of a trusted brand. Positioned similarly to the XTOOL D7 in terms of features, the CRP919E also delivers on its promise of comprehensive active tests. Our tests highlighted its remarkable speed – booting up in just 30 seconds and retrieving the VIN in about a minute, matching the rapid performance of the Autel MK808S.
A key advantage of the Launch CRP919E is its extensive suite of 31 service functions, exceeding what is offered by both the Autel MK808S and XTOOL D7. While the availability of specific service functions can vary by vehicle model, this broad range is a significant plus. It is always recommended to verify function compatibility with your specific vehicle before purchasing.
The main drawback we identified is in the live data display. While the data streams quickly and smoothly, graphed live data is only presented in combined graphs. Unlike the XTOOL D7, the Launch CRP919E does not offer the option to view individual graphs for each PID, which might be preferred for detailed analysis.
However, the Launch CRP919E stands out with its unique combination of a touchscreen and physical buttons. This hybrid control system enhances usability, particularly in a workshop environment where users might be wearing gloves or have dirty hands.
