Top OBD2 Scanners for Home Mechanics: Balancing Features and Price
For home mechanics looking for the best selling automotive diagnostic scanner that combines professional features with user-friendly operation, the INNOVA 5610 emerges as a leading contender. Alongside the Innova 5610, the Autel MK808S and the Launch CRP919E also present compelling alternatives worth considering for their capabilities and value.
#1. Innova 5610: A Feature-Rich Scanner for DIY Enthusiasts
Helpful link: Innova vehicle coverage checker
Pros:
- Affordable price point for home mechanics
- Fast and efficient performance
- Free lifetime updates included
Cons:
- Bi-directional control functionality is limited
- Printed manual not included in the box
The INNOVA 5610 stands out as a professional-grade OBD2 scanner perfectly suited for home use, primarily due to its inclusion of bidirectional control. This advanced feature allows users to perform active tests on vehicle systems, particularly the engine. Our testing revealed that the Innova 5610 supports approximately 10 active tests for the engine system, enabling actions like controlling the cooling fan and adjusting engine volume. These tests proved reliable, establishing seamless communication and providing immediate responses between the scanner and the vehicle’s systems. While the number of bi-directional tests is somewhat limited compared to more advanced scanners, the performance of those available is notably robust.
Mirroring the performance of the INNOVA 5210, the 5610 model maintains impressive speed during diagnostics. Scanning all vehicle systems is completed generally in under a minute, even though it takes slightly longer than scanners focused on fewer systems. Live data is readily available in under 15 seconds. However, the extensive array of data parameters (PIDs) might be overwhelming for less experienced users. A key observation is that the INNOVA 5610 lacks integrated explanations for each PID, requiring users to seek definitions independently, which could be a hurdle for some.
A specific limitation we noted was with the ABS Bleeding function on the INNOVA 5610. While other special functions like oil reset and battery reset performed effectively across our test vehicles, the ABS Bleeding function only showed compatibility with approximately 60% of vehicles tested. This reduced compatibility for ABS bleeding is a point to consider depending on your vehicle maintenance needs.
#2. Autel MK808S: Reputable Brand with Exceptional Speed
Pros:
- Comprehensive bi-directional control capabilities
- Product from a well-respected and reputable brand
- Very fast and responsive performance
Cons:
- Does not support ECU coding functions
If you are searching for a dependable and budget-friendly option from a recognized brand, the Autel MK808S is a strong contender for the best selling automotive diagnostic scanner in its category. Our tests highlighted several key strengths of this tool.
As a product from Autel, a leading name in diagnostic tools, the MK808S delivers on expectations for effectiveness and user-friendliness. During our comparative testing against the XTOOL D7 and Launch CRP919E, the Autel MK808S consistently demonstrated the fastest response times. Autel has enhanced the hardware in this model for improved efficiency, setting it apart from competitors in the same price bracket.
The interface of the MK808S is designed for ease of use, a feature positively noted by our testing team. We encountered no operational issues, making it accessible even for users with less experience.
While the MK808S is an excellent choice for many new professionals and home mechanics, it does lack ECU coding, a feature available in the D7 and CRP919E models. This is a trade-off to consider when choosing a scanner from a more established brand that prioritizes core diagnostic functions and reliability over niche features at this price point.
However, it’s important to emphasize that despite lacking ECU coding, the MK808S excels in other critical areas, including full-system diagnostics, active tests, and a wide range of service functions. These features operate exceptionally well and smoothly, ensuring a robust diagnostic experience.
#3. Launch CRP919E Elite: Versatility with Touchscreen and Buttons
Pros:
- Combines touchscreen interface with physical buttons for ease of use
- Full support for active tests across systems
- Impressive speed in operation
- Product from a reputable and trusted brand
Cons:
- Live data graphs are combined, no separate graphs for individual PIDs
If you’re seeking a scanner that offers ECU coding capabilities, similar to the XTOOL D7, but also values the reliability associated with a well-known brand, the Launch CRP919E is an ideal candidate for the best selling automotive diagnostic scanner that meets these criteria.
Much like the XTOOL D7, the Launch CRP919E lives up to expectations in performing active tests comprehensively. During our testing, its speed was particularly remarkable—powering up in just 30 seconds and retrieving the VIN in about a minute, placing it on par with the fast Autel MK808S.
A standout feature of the Launch CRP919E is its extensive suite of 31 service functions, exceeding what is offered by the Autel MK808S or XTOOL D7. It’s important to verify the availability of specific service functions for your particular car model before purchase, as compatibility can vary.
The primary drawback we identified is in its live data display. While it is fast and updates smoothly, it only presents 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 might be preferred for detailed analysis by some users.
However, the Launch CRP919E distinguishes itself with a unique combination of a touchscreen and physical buttons. This design makes it exceptionally user-friendly in various workshop conditions, even when operating with dirty hands or while wearing gloves, enhancing its practicality in a professional environment.
