Top Professional OBD2 Scanners for Home Mechanics
For the discerning home mechanic who demands professional-level features without breaking the bank, the INNOVA 5610 emerges as the leading choice. Excellent alternatives to consider are the Autel MK808S and the Launch CRP919E, each offering a unique blend of capabilities for advanced home diagnostics.
#1. Innova 5610
Helpful link: Innova vehicle coverage checker
Pros:
- Budget-friendly pricing makes it accessible to home mechanics.
- Quick and efficient performance for fast diagnostics.
- Free lifetime updates ensure long-term value and functionality.
Cons:
- Bidirectional controls are somewhat limited compared to higher-end scanners.
- Does not include a printed manual, which some users may prefer.
The INNOVA 5610 is a standout professional OBD2 scanner designed for home use, primarily distinguished by its bidirectional control capabilities. This feature allows users to perform active tests directly on the engine system. During our testing, we observed robust support for approximately 10 engine system tests, including cooling fan control and volume adjustments. These tests demonstrated dependable and responsive communication between the scanner and the vehicle, providing near-instantaneous feedback to commands.
Mirroring the impressive speed of the INNOVA 5210, the 5610 model maintains rapid performance. While scanning all vehicle systems naturally takes a bit longer than scanners focused on fewer systems, the INNOVA 5610 generally completes a full system scan in under a minute. Live data is displayed in less than 15 seconds. However, the extensive array of data parameters (PIDs) might be overwhelming for less experienced users. A notable drawback is the lack of built-in PID explanations, requiring users to independently research definitions.
A significant limitation we encountered is with the ABS Bleeding function on the INNOVA 5610. While other special functions, such as oil reset and battery reset, functioned effectively on our test vehicles, the ABS Bleeding function only supported approximately 60% of the vehicles tested, indicating a potential compatibility issue for some users.
#2. Autel MK808S
Pros:
- Comprehensive bidirectional control for in-depth diagnostics.
- Manufactured by Autel, a highly respected and reputable brand in the industry.
- Exceptional speed and responsiveness during testing.
Cons:
- Lacks ECU coding capabilities, a feature found in some competitors.
If you’re seeking a dependable and cost-effective professional OBD2 scanner from a well-established brand, the Autel MK808S is a highly recommended choice. Our extensive testing revealed several key strengths:
As a product from Autel, a leader in automotive diagnostic tools, the MK808S offers guaranteed reliability and user-friendliness. Its responsiveness was particularly impressive during our evaluations. In a speed comparison against the XTOOL D7 and Launch CRP919E, the Autel MK808S proved to be the fastest. Autel has upgraded the hardware in this model to enhance efficiency, setting it apart from other scanners in a similar price bracket, such as the XTOOL D7 or Launch CRP919E.
Our testing team also praised the intuitive user interface of the MK808S, reporting a smooth and hassle-free operational experience.
While the MK808S is an excellent professional-grade scanner for most users, particularly new professionals, it does omit ECU coding, a feature available in the XTOOL D7 and CRP919E. This is a trade-off to consider when prioritizing a scanner from a more established and trusted brand.
However, be assured that while ECU coding is absent, the Autel MK808S excels in other critical areas, including full-system diagnostics, active tests, and a wide array of service functions, all executed with exceptional efficiency and stability.
#3. Launch CRP919E Elite
Pros:
- Unique combination of touchscreen and physical buttons for versatile operation.
- Full support for active tests, enhancing diagnostic capabilities.
- Remarkably fast performance, saving time during diagnostics.
- Product of Launch, a reputable and trusted brand in automotive diagnostics.
Cons:
- Unable to display separate graphs for individual PIDs in live data.
If you are looking for a professional OBD2 scanner that merges ECU coding capabilities, similar to the XTOOL D7, with the reliability associated with a reputable brand, the Launch CRP919E is an ideal match.
Like the XTOOL D7, the Launch CRP919E lives up to expectations in performing active tests effectively. We were particularly impressed by its rapid speed during testing – it powers on in a mere 30 seconds and retrieves the VIN in just one minute, positioning it on par with the speed of the Autel MK808S.
A standout advantage of the Launch CRP919E is its extensive suite of 31 service functions, exceeding the offerings of both the Autel MK808S and XTOOL D7. It’s important to verify the availability of specific functions for your vehicle model before purchase, as compatibility can vary.
The primary limitation we identified is in its live data display. While the data is presented quickly and smoothly, it only offers combined graphs when viewing graphed live data. Unlike the XTOOL D7, the Launch CRP919E does not provide the option to view individual graphs for each PID simultaneously.
However, the Launch CRP919E distinguishes itself with a unique design that incorporates both a touchscreen and physical buttons. This hybrid interface enhances user-friendliness, especially in workshop environments where users may be wearing gloves or have greasy hands.
