Top OBD2 Scanner Picks for Home Mechanics
For the dedicated home mechanic seeking a professional-grade diagnostic tool without breaking the bank, the INNOVA 5610 emerges as our top recommendation. Excellent alternatives worth considering are the Autel MK808S and the Launch CRP919E, each offering a blend of features and value.
#1. Innova 5610
Helpful link: Innova vehicle coverage checker
Pros:
- Affordable price point, making it accessible for home users.
- Quick and efficient performance, saving time during diagnostics.
- Lifetime free updates, ensuring long-term value and functionality.
Cons:
- Limited bi-directional control capabilities compared to higher-end models.
- No printed manual included, which might be inconvenient for some users.
The INNOVA 5610 is specifically designed for home use but boasts professional-grade features, most notably its bidirectional control. This essential function allows users to perform active tests on vehicle systems, particularly the engine system. During our testing, the Innova 5610 reliably executed approximately 10 active tests for the engine, including cooling fan control and volume adjustments. The scanner demonstrated consistent and dependable communication with the test vehicles, providing immediate responses to commands.
Echoing the impressive speed of the INNOVA 5210, the 5610 model maintains rapid performance. While scanning all vehicle systems takes slightly 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, allowing for quick access to crucial information. However, the wealth of data parameters (PIDs) might initially overwhelm less experienced users. It’s worth noting that the INNOVA 5610 doesn’t provide built-in explanations for each PID, requiring users to seek definitions independently.
One noted limitation of the INNOVA 5610 is the ABS Bleeding function. While other special functions like oil reset and battery reset performed effectively across our test vehicles, the ABS Bleeding function showed limited vehicle support, working on approximately 60% of the cars we tested.
#2. Autel MK808S
Pros:
- Comprehensive bi-directional control for in-depth diagnostics.
- Product of Autel, a highly reputable and trusted brand in the automotive diagnostic industry.
- Exceptionally fast performance, enhancing workflow efficiency.
Cons:
- Lacks ECU coding capabilities, a feature found in some competing models.
If you’re seeking a dependable and budget-conscious scanner from a leading brand, the Autel MK808S is a strong contender. Our testing highlighted several key strengths:
As a product from Autel, a well-established name in automotive diagnostics, the MK808S inspires confidence in its effectiveness and user-friendliness. Its responsiveness was particularly notable during our evaluations. In direct comparisons with the Autel MK808S, XTOOL D7, and Launch CRP919E, the MK808S consistently demonstrated the fastest performance. Autel has invested in hardware upgrades that significantly boost efficiency, setting it apart from similarly priced scanners like the XTOOL D7 and Launch CRP919E.
Our testing team also praised the user-friendly interface design, experiencing seamless and intuitive operation throughout the testing process.
While the MK808S is an excellent choice for many new professionals and experienced home mechanics, it omits ECU coding, a feature present in the D7 and CRP919E. This trade-off is a consideration when opting for a more established brand known for reliability and ease of use.
However, it’s important to emphasize that despite lacking ECU coding, the Autel MK808S excels in other critical areas. Its full-system diagnostics, active tests, and service functions operate exceptionally smoothly and effectively, providing robust diagnostic coverage.
#3. Launch CRP919E Elite
Pros:
- Unique combination of touchscreen and physical buttons for versatile operation.
- Full support for active tests, enabling comprehensive system evaluations.
- Impressive speed, enhancing diagnostic efficiency.
- Product from Launch, a reputable and recognized brand in the automotive industry.
Cons:
- Limited live data graphing, only displaying combined graphs.
If you’re looking for a scanner that blends ECU coding capabilities, similar to the XTOOL D7, with the trusted reliability of a well-known brand, the Launch CRP919E is an ideal option.
Mirroring the XTOOL D7, the Launch CRP919E delivers on its promise of comprehensive active tests. During our testing, we were particularly impressed by its remarkable speed – powering up in a mere 30 seconds and retrieving the VIN in just a minute, placing it on par with the rapid Autel MK808S.
The standout feature 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 crucial 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 fast and smooth in updates, 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.
However, the Launch CRP919E distinguishes itself with its unique combination of a touchscreen interface and physical buttons. This design makes it exceptionally user-friendly, even when working with dirty hands or while wearing gloves, a common scenario in automotive repair environments.
