4. Detailed Reviews of the Best Car Diagnostic Tools

What are the best car diagnostic tools currently available, and what are their pros and cons? To help you make an informed decision, we’ve compiled detailed reviews of some of the top car diagnostic tools on the market. These reviews are based on extensive testing and analysis, considering factors such as performance, features, ease of use, and value for money.

4.1. Best Professional OBD2 Scanners for Home Mechanics

What are the best OBD2 scanners for home mechanics who need a balance of features and affordability? For home mechanics seeking the optimal tool, the INNOVA 5610 stands out as the top choice. Alternatively, considerations can also be given to the Autel MK808S and the Launch CRP919E.

4.1.1. Innova 5610

Pros:

• Affordable pricing
• Relatively fast performance
• Lifetime free updates

Cons:

• Limited bi-directional controls
• Absence of a printed manual

The INNOVA 5610, tailored for home use, is a professional OBD2 scanner distinguished by its bidirectional control feature, enabling active tests on the engine system. Although the scanner impressively supports approximately 10 tests for the engine system, such as controlling the cooling fan or adjusting volume, the overall count is somewhat limited. These tests exhibit reliable performance, fostering smooth communication between the scanner and the vehicle, with immediate responses to each command.

Similar to the previously mentioned INNOVA 5210, the INNOVA 5610 maintains an impressive speed. While scanning all vehicle systems, which may take slightly longer compared to scanners focusing on three systems, it generally completes the task in under 1 minute, with live data displayed in less than 15 seconds. However, users with limited experience might find the abundance of data parameters (PIDs) overwhelming. Notably, the INNOVA 5610 lacks clear explanations for each PID, requiring users to independently search for definitions.

A noteworthy issue pertains to the ABS Bleeding function of the INNOVA 5610. While other special functions like oil reset and battery reset performed well on our test vehicles, the ABS Bleeding function supports only around 60% of vehicles, posing a limitation.

4.1.2. Autel MK808S

Pros:

• Full bi-directional control supported
• Product from a reputable brand
• Very fast performance

Cons:

• No ECU coding supported

If you’re in the market for a reliable and budget-friendly scanner from a reputable brand, we recommend the Autel MK808S. Being a product of the well-known brand Autel, you can trust its effectiveness and ease of use. During our testing, its responsiveness stood out significantly. Among the Autel MK808S, XTOOL D7, and Launch CRP919E, the Autel MK808S proved to be the fastest. Autel has upgraded its hardware to enhance efficiency, setting it apart from other scanners in the same price range, such as the XTOOL D7 or Launch CRP919E.

The user-friendly design of the interface was another positive aspect highlighted by our testing team, experiencing no issues with its operation. While the MK808S is an excellent choice for most new professionals, it does lack one feature present in the D7 and CRP919E – ECU coding. However, this is a trade-off that comes with opting for a more established brand. Nevertheless, rest assured that while it may lack this particular function, its other features such as full-system diagnostics, active tests, and service functions perform exceptionally well and smoothly.

4.1.3. Launch CRP919E Elite

Pros:

• Combination of touch screen and physical buttons
• Full support for active tests
• Impressive speed
• Product from a reputable brand

Cons:

• Inability to view separate graphs

If you’re in the market for a scanner that combines ECU coding capabilities, akin to the XTOOL D7, with the reliability of a trusted brand, the Launch CRP919E fits the bill. Much like the XTOOL D7, the Launch CRP919E lives up to its promise of performing active tests. What particularly impressed us during testing was its remarkable speed—it powers up in just 30 seconds and retrieves the VIN in a mere minute, placing it on par with the Autel MK808S.

The standout feature of the Launch CRP919E lies in its extensive array of 31 service functions, surpassing what the Autel MK808S or XTOOL D7 offer. It’s essential to note that the availability of these functions can vary depending on your specific car model, so it’s advisable to double-check before making a purchase. The primary drawback lies in the live data display. While it is fast and updates smoothly, it only presents combined graphs when viewing graphed live data. Unlike the XTOOL D7, the Launch CRP919E lacks the option to view individual graphs for each PID. However, what sets the Launch CRP919E apart is its unique combination of a touchscreen and physical buttons. This feature makes it user-friendly, even when handling the device with dirty hands or gloves.
