Top OBD2 Scanner Picks for Home Mechanics
For home mechanics seeking a balance of professional features and user-friendliness, the INNOVA 5610 emerges as our top recommendation. Alternatives worth considering are the Autel MK808S and the Launch CRP919E, each offering a unique set of capabilities.
#1. Innova 5610: The Versatile Choice for DIYers
Helpful link: Innova vehicle coverage checker
Pros:
- Affordable professional car diagnostic tool
- Fast and efficient performance
- Lifetime free updates for continuous improvement
Cons:
- Bi-directional control functions are somewhat limited compared to higher-end tools
- No printed manual included in the package
The INNOVA 5610 is a professional OBD2 scanner designed with the home mechanic in mind, emphasizing bidirectional control for conducting active tests on engine systems. While it capably supports around 10 active tests for engine functions—such as cooling fan control and volume adjustments—the total number of tests is moderately limited. However, these tests are reliably executed, ensuring seamless communication and instant command response between the scanner and the vehicle.
Mirroring the INNOVA 5210’s performance, the INNOVA 5610 operates with impressive speed. Scanning all vehicle systems is completed generally in under a minute, even if it takes slightly longer than scanners focused on fewer systems. Live data is accessible in under 15 seconds. However, the extensive array of data parameters (PIDs) might be overwhelming for less experienced users. A key drawback is the INNOVA 5610’s lack of integrated PID explanations, requiring users to independently research definitions.
A notable limitation is the ABS Bleeding function’s vehicle support on the INNOVA 5610. While other special functions like oil reset and battery reset performed effectively in our tests, ABS Bleeding is compatible with only about 60% of vehicles tested, which could be a significant constraint for some users.
#2. Autel MK808S: Reputable Brand with Rapid Diagnostics
Pros:
- Comprehensive bi-directional control for in-depth diagnostics
- Product of a highly reputable and trusted brand in automotive diagnostics
- Exceptionally fast performance, saving time during diagnoses
Cons:
- Lacks ECU coding capabilities, a feature found in some competitors
If you’re seeking a dependable, budget-friendly professional car scanner diagnostic tool from a well-regarded brand, the Autel MK808S is highly recommended. Our tests highlighted several key advantages:
As an Autel product, the MK808S offers assurance of effectiveness and user-friendliness. Its responsiveness was particularly noticeable in our tests. In a direct comparison with the XTOOL D7 and Launch CRP919E, the Autel MK808S proved to be the quickest. Autel’s hardware upgrades have significantly boosted its efficiency, distinguishing it from competitors in the same price range.
The interface design is notably user-friendly, a point consistently praised by our testing team, who reported a smooth and intuitive user experience.
While the MK808S is an excellent professional-grade scanner for many technicians, it does not include ECU coding, a feature available in the D7 and CRP919E. This is a trade-off to consider when prioritizing a scanner from a more established and recognized brand.
Despite this missing feature, the Autel MK808S excels in other critical areas such as full-system diagnostics, active tests, and a wide range of service functions, all performed with exceptional smoothness and reliability.
#3. Launch CRP919E Elite: Feature-Rich with User-Friendly Design
Pros:
- Combines touch screen operation with physical buttons for versatile control
- Full support for active tests, enhancing diagnostic capabilities
- Impressively fast boot-up and VIN retrieval speeds
- Product from a reputable brand known for quality diagnostic tools
Cons:
- Live data graphing limited to combined graphs, no separate graphs available
For those needing ECU coding capabilities combined with the reliability of a trusted brand, the Launch CRP919E is an excellent choice. It mirrors the XTOOL D7 in ECU coding functionality while offering the brand assurance of Launch.
Like the XTOOL D7, the Launch CRP919E effectively performs active tests. Its speed was particularly impressive in our evaluations—powering on in just 30 seconds and retrieving the VIN in a mere minute, matching the rapid performance of the Autel MK808S.
A standout feature of the Launch CRP919E is its extensive suite of 31 service functions, surpassing both the Autel MK808S and XTOOL D7. It’s important to verify function availability for your specific vehicle model before purchasing.
The primary drawback noted is in live data display. While fast and fluid, it only displays combined graphs for graphed live data, lacking the individual PID graph option found in the XTOOL D7.
However, the Launch CRP919E distinguishes itself with a unique combination of touchscreen and physical buttons. This design enhances usability, especially in workshop environments where users might be wearing gloves or have dirty hands.
