Best OBD2 Scanners for Home Mechanics
For those who enjoy tinkering with their cars at home, having a reliable OBD2 scanner is invaluable. The INNOVA 5610 emerges as our top recommendation in this category, offering a blend of professional features and user-friendliness. The Autel MK808S and Launch CRP919E also deserve strong consideration, providing robust capabilities for home-based diagnostics and repairs.
#1. Innova 5610
Helpful link: Innova Vehicle Coverage Checker
Pros:
- Affordable price point makes it accessible for home users.
- Fast performance ensures quick diagnostic checks.
- Lifetime free updates provide long-term value.
Cons:
- Bi-directional controls are somewhat limited compared to higher-end models.
- Does not include a printed manual, which some users may prefer.
The INNOVA 5610 is specifically designed for home mechanics, offering professional-grade features in an accessible package. A standout feature is its bidirectional control, enabling users to perform active tests on the engine system. During our tests, we found it reliably supported around 10 active tests for engine components, such as cooling fan control and volume adjustments. The scanner demonstrated excellent communication with test vehicles, delivering immediate and reliable responses.
In terms of speed, the INNOVA 5610 is impressively quick, mirroring the performance of the INNOVA 5210. It completes full system scans in under a minute and displays live data within 15 seconds. While the wealth of Parameter IDs (PIDs) might be overwhelming for novice users, experienced mechanics will appreciate the detailed data. However, it’s worth noting that the INNOVA 5610 lacks built-in explanations for each PID, requiring users to potentially look up definitions independently.
One area where the INNOVA 5610 showed limitations is the ABS Bleeding function. While other special functions like oil reset and battery reset worked effectively across our test vehicles, ABS Bleeding compatibility was limited to approximately 60% of vehicles. This is a factor to consider depending on your specific needs and vehicle types.
#2. Autel MK808S
Pros:
- Comprehensive full bi-directional control for advanced diagnostics.
- From Autel, a reputable and trusted brand in automotive diagnostics.
- Very fast performance speeds up diagnostic workflows.
Cons:
- No ECU coding capabilities, which may be needed for certain advanced repairs.
If brand reputation and reliability are high on your priority list, the Autel MK808S is an excellent, budget-friendly choice. Our testing highlighted its exceptional responsiveness. In a speed comparison against the XTOOL D7 and Launch CRP919E, the Autel MK808S proved to be the fastest. Autel’s hardware upgrades have significantly improved efficiency, setting it apart from competitors in the same price range.
The user-friendly interface was another key positive aspect noted by our testing team. We experienced smooth and intuitive operation throughout our evaluations.
While the MK808S is a strong contender for new professionals and experienced home mechanics, it lacks ECU coding, a feature found in the XTOOL D7 and CRP919E. This trade-off is often associated with choosing a more established brand known for reliability and ease of use.
Despite lacking ECU coding, the Autel MK808S excels in other critical areas, including full-system diagnostics, active tests, and service functions, all performing exceptionally well and seamlessly.
#3. Launch CRP919E Elite
Pros:
- Unique combination of touch screen and physical buttons for versatile operation.
- Full support for active tests for comprehensive diagnostics.
- Impressive speed for quick results.
- Product from Launch, a reputable brand in diagnostic tools.
Cons:
- Inability to view separate graphs for live data, limiting detailed analysis.
For users seeking a balance of advanced features and brand trustworthiness, the Launch CRP919E Elite is a compelling option. It combines ECU coding capabilities, similar to the XTOOL D7, with the established reliability of the Launch brand.
Like the XTOOL D7, the Launch CRP919E delivers on its promise of robust active test performance. We were particularly impressed by its speed – powering up in just 30 seconds and retrieving the VIN in about a minute, matching the rapid performance of the Autel MK808S.
A key selling point of the Launch CRP919E Elite is its extensive suite of 31 service functions, surpassing the offerings of the Autel MK808S and XTOOL D7. However, service function availability can vary by car model, so verifying compatibility with your vehicles before purchase is recommended.
The primary drawback we identified is in the live data display. While fast and smooth, graphed live data is presented only in combined graphs. Unlike the XTOOL D7, the Launch CRP919E does not offer individual graphs for each PID, which might limit in-depth data analysis for some users.
However, the Launch CRP919E stands out with its hybrid touchscreen and physical button interface. This design offers user-friendliness in various working conditions, even when operating with gloves or dirty hands.
