For automotive enthusiasts and car owners looking to delve deeper into vehicle diagnostics beyond basic error code reading, a simple, low-cost OBDII scanner might not suffice. While devices like a $13 Bluetooth ELM 327 dongle paired with a phone app are readily accessible, their capabilities are limited, especially when it comes to accessing non-OBDII systems and retrieving data like oil level – which isn’t part of standard OBDII parameters. These basic tools primarily focus on emissions-related issues and lack the sophistication needed for comprehensive vehicle analysis.
To truly interact with the intricate network of computers in a modern vehicle and perform advanced diagnostics, you’ll need to invest in a more capable scan tool. These advanced devices bridge the gap between basic OBDII readers and professional-grade equipment, offering enhanced functionalities without the hefty price tag of dealership-level tools.
At the entry point for advanced scanning, options like Autel’s DiagLink emerge as contenders. Priced around $90-$100, the DiagLink distinguishes itself by offering non-OBDII system access, enabling functions like resetting service lights and managing electronic parking brakes – features beyond the reach of basic OBDII scanners. However, the DiagLink operates on a brand-specific basis. Each unit comes with software for a single car brand, chosen by the user upon initial setup. While additional brand software can be purchased for approximately $10 per brand, this limitation is a crucial factor to consider. For individuals dedicated to a single vehicle brand, the DiagLink presents a cost-effective solution for in-depth diagnostics.
For those working with multiple vehicle brands, a more versatile option is required. Autel’s MD806, priced around $200, offers a multi-brand diagnostic capability. While it likely shares hardware similarities with the DiagLink, the MD806 utilizes software that supports diagnostics across various manufacturers without the need for separate brand-specific software purchases. Furthermore, the MD806 typically includes free lifetime software updates, ensuring ongoing compatibility and functionality. It’s important to note that “lifetime” in software terms usually refers to the product’s support lifespan, but for the foreseeable ownership period, the MD806 provides excellent value.
In conclusion, when searching for the best car scan tool in 2021, the optimal choice depends heavily on your specific needs and the depth of diagnostics you intend to perform. For basic OBDII code reading, inexpensive tools are adequate. However, for accessing non-OBDII systems and performing more advanced functions, consider tools like the Autel DiagLink for single-brand use or the Autel MD806 for multi-brand versatility. These options represent a significant step up in capability while remaining accessible to the home mechanic and car enthusiast, making them strong contenders for the best car scan tool for enhanced vehicle diagnostics.
