Top OBD2 Scanner Tools for Home Mechanics
For home mechanics looking for a balance of professional features and user-friendliness, we’ve identified three excellent OBD2 scanner tools. The INNOVA 5610 tops our list in this category, closely followed by the Autel MK808S and the Launch CRP919E.
#1. INNOVA 5610
Helpful link: Innova vehicle coverage checker
Pros:
- Affordable and excellent value for money
- Fast and efficient performance
- Lifetime free updates ensure long-term usability
Cons:
- Bi-directional controls are somewhat limited compared to higher-end models
- No printed manual included
The INNOVA 5610 stands out as a professional OBD2 scanner specifically designed for home mechanics, primarily due to its bidirectional control capabilities. This feature allows users to perform active tests on engine systems, such as controlling the cooling fan or adjusting idle speed, directly from the scanner. While it supports around 10 active tests for the engine system, which is fewer than some professional-grade scanners, the tests we performed were consistently reliable. The communication between the scanner and the vehicle was seamless, with commands executed and responses received instantly.
Speed is another area where the INNOVA 5610 excels, mirroring the performance of the INNOVA 5210. Scanning all vehicle systems takes slightly longer than scanners focused on fewer systems, but it generally completes within a minute. Displaying live data is impressively fast, appearing in under 15 seconds. However, the extensive amount of data parameters (PIDs) might be overwhelming for less experienced users. The INNOVA 5610 does not provide built-in explanations for each PID, requiring users to look up definitions independently.
One limitation we observed is with the ABS Bleeding function. While other special functions like oil reset and battery reset worked well during our tests, the ABS Bleeding function only supports approximately 60% of vehicles, which might be a constraint depending on the vehicles you work on.
#2. Autel MK808S
Pros:
- Comprehensive bi-directional control for extensive testing
- Product from a highly reputable and trusted brand, Autel
- Exceptionally fast performance enhances efficiency
Cons:
- Lacks ECU coding capabilities, a feature found in some competitors
If you prioritize reliability and brand reputation without breaking the bank, the Autel MK808S is an excellent choice. Our testing highlighted several key strengths of this scanner.
As a product from Autel, a leading brand in automotive diagnostics, the MK808S offers guaranteed effectiveness and user-friendliness. Its responsiveness was particularly impressive during our tests. In a direct comparison with the XTOOL D7 and Launch CRP919E, the Autel MK808S proved to be the fastest in operation. Autel has upgraded the internal hardware, giving it a performance edge over similarly priced scanners like the XTOOL D7 and Launch CRP919E.
Our testing team also praised the user-friendly interface, noting a smooth and intuitive operation.
While the MK808S is a fantastic tool for most mechanics, particularly those newer to the profession, it does miss out on ECU coding, a feature available in the D7 and CRP919E. However, this is a trade-off for choosing a more established and reliable brand.
Despite lacking ECU coding, the Autel MK808S excels in other critical areas, including full-system diagnostics, active tests, and a wide range of service functions, all performing smoothly and efficiently.
#3. Launch CRP919E Elite
Pros:
- Unique combination of touchscreen and physical buttons for versatile use
- Full support for active tests, enhancing diagnostic capabilities
- Impressive speed in boot-up and VIN retrieval
- Product from Launch, another reputable brand in diagnostic tools
Cons:
- Live data graphs are combined, lacking individual PID graph viewing
If you need ECU coding capabilities alongside the reliability of a well-known brand, the Launch CRP919E is a strong contender, similar to the XTOOL D7 but with the backing of Launch’s reputation.
The Launch CRP919E delivers on its promise of comprehensive active tests, just like the XTOOL D7. We were particularly impressed by its speed. It boots up in just 30 seconds and retrieves the VIN in about a minute, matching the rapid performance of the Autel MK808S.
A key selling point 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 the availability of specific functions for your vehicle model before purchase, as compatibility can vary.
The primary drawback we noted is in the live data display. While fast and fluid, it only displays combined graphs for live data, unlike the XTOOL D7, which allows viewing individual graphs for each PID.
However, the Launch CRP919E distinguishes itself with a user-friendly design that integrates both a touchscreen and physical buttons. This hybrid approach makes it easy to operate, even when your hands are dirty or gloved.
