Considering an upgrade to a professional-grade OBDII diagnostic scan tool? Or perhaps you’re already invested in the Autel Ultra, MS919, or MS909 platform and have mixed feelings? Let’s dive into a real-world review of these popular scan tools, drawing from extensive hands-on experience and opening the floor for community feedback. After two years of using the Autel Ultra, I’ve developed a solid understanding of its strengths and weaknesses, and I’m eager to share my insights to help you make an informed decision. While it’s brought significant improvements to my diagnostic workflow, it’s important to be realistic – no tool is without its imperfections.
What I Love About the Autel OBDII Scan Tool Platform
One of the most significant advantages of the Autel Ultra/MS919/MS909 series is its impressive code scan speed. Autel has implemented an “Autoscan 2.0” feature for a growing list of manufacturers, and it truly revolutionizes the initial diagnostic process. The speed is remarkable – going from zero codes to a complete scan of all modules in mere seconds. This rapid assessment saves valuable time and allows for quicker initial diagnosis.
Sharing diagnostic information is also streamlined. The ability to share code reports directly via email or text message from the scan tool is incredibly convenient. Whether you’re collaborating with fellow technicians, updating shop management, or communicating with customers, this feature simplifies information dissemination and enhances workflow efficiency.
The wireless diagnostic scope has proven to be an indispensable asset. Setting up the scope in the engine bay and operating the scanner from inside the vehicle cab becomes effortless. This wireless capability significantly reduces the hassle of tangled cables and the need for assistance from another technician when cranking the engine or manipulating the throttle during tests. The ease of use directly translates to more frequent and effective utilization of the scope function.
Even when used in a traditional wired configuration, the diagnostic scope itself is a powerful addition to any repair arsenal. Setup is straightforward, and obtaining waveform readings is quick. While it may not match the absolute pinnacle of diagnostic oscilloscopes like Pico, it readily handles approximately 95% of the tasks that automotive technicians encounter daily. It provides ample functionality for users of all skill levels, including advanced features for those who require deeper analysis.
Autel’s commitment to improvement is evident in their frequent and valuable updates. While updates include new model year coverage, the true value lies in the continuous addition of new features like Autoscan 2.0 and cloud-based report sharing. Using an up-to-date Autel Ultra today offers a significantly enhanced experience compared to its capabilities just two years prior. This ongoing development ensures that the tool remains relevant and powerful in a rapidly evolving automotive landscape.
Finally, the J2534 pass-thru programming function has consistently performed reliably. Compatibility with OEM software such as FJDS, FDRS, Techline Connect, NERS, and HDS has been seamless. The VCMI (Vehicle Communication Measurement Interface) firmware, crucial for this functionality, receives regular updates alongside the main scan tool software, further ensuring compatibility and performance.
Areas for Improvement in Autel OBDII Scan Tools
The bus inspection tool, while conceptually intriguing, hasn’t proven as transformative in practice as initially anticipated. Perhaps due to specific work environments or vehicle types encountered, the benefits of this feature have been limited. It occasionally saves a trip to the toolbox for a breakout box, but its impact on daily diagnostics is not substantial. If network resistance measurement were incorporated, its utility could be significantly elevated.
Similarly, the waveform generator and actuator drive functions are interesting but lack frequent real-world application in routine auto repair. While their potential is undeniable – the signal generator has been used to test ABS wiring, and the actuator drive remotely activated a fuel pump relay – these instances are infrequent. These features are certainly not useless, but their day-to-day practicality could be enhanced with more readily applicable scenarios.
Storing and retrieving diagnostic scope waveforms is an area that needs considerable refinement. A system exists for tagging captures with vehicle information (Year, Make, Model, Engine) and waveform specifics. However, the vehicle list is often incomplete, missing years, models, and even major manufacturers. This deficiency significantly hinders the ability to effectively search and retrieve saved waveforms later. Furthermore, while waveform tagging allows for categories like solenoid or fuel pump, pressure transducers are notably absent. Exporting captures is also severely limited, with an online library upload option that lacks clear benefits for users.
Despite Autel’s reputation for comprehensive bidirectional controls, bidirectional tests and resets can still be surprisingly limited at times. A primary reason for choosing the Ultra was to expand coverage beyond existing Snap-On and Launch tools. While it has largely achieved this goal, there are still instances where reaching for another scan tool becomes necessary, more often than initially expected. For a brand known for its “magic button” capabilities, this aspect can be somewhat disappointing.
Drawbacks of the Autel OBDII Diagnostic Platform
Graphing scan data is arguably the weakest aspect of the Autel Ultra/MS919/MS909 platform, especially for users accustomed to the graphing capabilities of tools like Snap-On. Graphing is simply subpar. Binary PIDs (Yes/No, On/Off, True/False) cannot be graphed at all. Scaling options are often inadequate. The absence of cursors makes precise data measurements cumbersome and time-consuming. When in-depth data analysis and graphing are required, the Autel platform is definitely not the preferred choice.
Reviewing saved data shares similar shortcomings. The lack of export options for captured data further restricts usability and analysis. This limitation makes it difficult to share or further analyze diagnostic data outside of the tool itself.
The physical size of the Autel Ultra/MS919/MS909 can be a practical issue. Its bulkiness means it frequently occupies valuable space, both on the toolbox and within the vehicle during use. While a VCMI holder can mitigate toolbox clutter, the scanner’s large footprint remains a consideration.
Finally, the included scope leads are of questionable quality. Premature solder joint failures at the ground banana jack were experienced with three out of four included leads. This necessitated replacing the factory leads with higher-quality alternatives to ensure reliable scope operation and prevent potential diagnostic errors. One lead even exhibited an internal short circuit between the signal and ground wires, highlighting a significant quality control concern.
Conclusion on Autel OBDII Diagnostic Scan Tool Reviews
Overall, the Autel Ultra/MS919/MS909 platform offers a powerful and feature-rich diagnostic experience. Its strengths in scan speed, wireless capabilities, update frequency, and J2534 functionality are undeniable. However, areas such as waveform storage, graphing, and bidirectional control coverage, along with concerns about component quality, indicate room for improvement. For technicians seeking a comprehensive OBDII diagnostic scan tool with advanced features, the Autel platform is a strong contender, but it’s crucial to be aware of both its advantages and limitations before making a purchase decision.
