Top OBD2 Scanner Tools for Home Mechanics
For home mechanics seeking the best balance of features and usability, the INNOVA 5610 is our top recommendation. The Autel MK808S and the Launch CRP919E also offer compelling features and should be considered.
#1. Innova 5610 – The Best OBD2 Scanner for Home Use
Helpful link: Innova vehicle coverage checker
Pros:
- Affordable OBD2 scanner price point
- Fast diagnostic performance
- Lifetime free software updates
Cons:
- Bi-directional controls are somewhat limited
- No printed user manual included
The INNOVA 5610 is designed for home mechanics and stands out as a professional-grade OBD2 scanner with bidirectional control capabilities, allowing for active tests of the engine system. This mechanic tool supports around 10 active tests for the engine, such as controlling the cooling fan and adjusting throttle volume. While the number of tests is not extensive, they perform reliably, ensuring smooth communication and quick response times between the scanner and the vehicle.
Like the INNOVA 5210, the 5610 is notably fast. Scanning all vehicle systems is completed in under a minute, and live data is displayed in less than 15 seconds. However, the extensive data parameters (PIDs) might be overwhelming for less experienced users. The INNOVA 5610 lacks built-in explanations for each PID, requiring users to research definitions independently.
A significant limitation is the ABS Bleeding function of the INNOVA 5610. While other special functions like oil reset and battery reset worked well in our tests, ABS Bleeding is only compatible with approximately 60% of vehicles, which could be a drawback for some users.
#2. Autel MK808S – Reliable OBD2 Scanner from a Trusted Brand
Pros:
- Full bi-directional control capabilities
- Product from a well-respected brand, Autel
- Very fast diagnostic speeds
Cons:
- Does not support ECU coding
If you are looking for a dependable and affordable OBD2 scanner from a reputable brand, the Autel MK808S is an excellent choice. Our testing highlighted several key features:
As a product from Autel, a leading brand in diagnostic tools, the MK808S offers reliability and user-friendliness. Its responsiveness was particularly impressive during our tests. In a comparison with the Autel MK808S, XTOOL D7, and Launch CRP919E, the Autel MK808S was the fastest. Autel has upgraded the hardware to enhance performance, setting it apart from competitors in the same price range like the XTOOL D7 or Launch CRP919E.
Our testing team also praised the user-friendly interface of the MK808S, noting a smooth and intuitive user experience.
While the MK808S is an excellent professional OBD2 scanner for many new mechanics, it lacks ECU coding, a feature found in the D7 and CRP919E. However, this trade-off comes with choosing a more established and trusted brand known for quality and reliability.
Despite lacking ECU coding, the Autel MK808S excels in other critical functions such as full-system diagnostics, active tests, and service functions, all of which performed exceptionally well and smoothly in our evaluations.
#3. Launch CRP919E Elite – Feature-Rich OBD2 Scanner for Mechanics
Pros:
- Combines touchscreen and physical buttons for ease of use
- Full support for active tests
- Impressive diagnostic speed
- Product from a reputable brand, Launch
Cons:
- Cannot display separate graphs for live data
If you need an OBD2 scanner that combines ECU coding capabilities, similar to the XTOOL D7, with the dependability of a trusted brand, the Launch CRP919E is a strong contender.
Like the XTOOL D7, the Launch CRP919E delivers on its promise of effective active tests. We were particularly impressed by its speed during testing—powering up in just 30 seconds and retrieving the VIN in only a minute, matching the speed of the Autel MK808S.
The Launch CRP919E stands out with its extensive suite of 31 service functions, exceeding what the Autel MK808S or XTOOL D7 offer. It’s important to verify the availability of these functions for your specific vehicle model before purchasing.
The primary drawback is in the live data display. While fast and smooth, it only shows 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.
However, the Launch CRP919E distinguishes itself with a unique combination of a touchscreen and physical buttons. This design makes it user-friendly even when working with dirty hands or while wearing gloves, a practical advantage for mechanics.
