An OBDII scan tool is essential for diagnosing car problems, but not all scanners are created equal. Basic code readers can only access limited OBDII data, insufficient for tasks like resetting oil change lights or servicing electric parking brakes. For comprehensive vehicle diagnostics, including non-OBDII systems, a more advanced scan tool is necessary. This article explores two of the Best Obdii Scan Tools on the market: the Autel DiagLink and the Autel MD806.
Delving into Advanced Diagnostics: Beyond Basic OBDII
Simple OBDII dongles with phone apps are inadequate for comprehensive car diagnostics. They primarily read basic OBDII codes and lack access to manufacturer-specific systems crucial for in-depth troubleshooting and maintenance. Accessing non-OBDII data, such as oil level (not directly part of OBDII), requires a specialized tool capable of communicating with the vehicle’s proprietary network. Tools like the Autel DiagLink and MD806 bridge this gap, offering functionalities beyond basic code reading.
Autel DiagLink: Brand-Specific Expertise
The Autel DiagLink, priced around $90-$100, offers a cost-effective solution for in-depth diagnostics. However, it operates on a brand-specific model. Upon purchase, users select one free manufacturer-specific software package to download and install. While this limits the device to a single car brand, it provides comprehensive functionality for that specific make, including advanced features like resetting oil change indicators and controlling electric parking brakes. Additional brand software can be purchased for approximately $10 each, offering flexibility for multi-car households.
Autel MD806: Multi-Brand Versatility
For users requiring multi-brand compatibility, the Autel MD806, priced around $200, provides a versatile solution. It boasts similar hardware to the DiagLink but includes software supporting multiple car brands without requiring separate downloads. The MD806 also offers lifetime software updates, ensuring access to the latest features and vehicle coverage. This “lifetime” typically refers to the expected support lifespan of the tool, generally around 15 years.
Choosing the Best OBDII Scan Tool: DiagLink vs. MD806
Both the Autel DiagLink and MD806 offer significant advantages over basic OBDII code readers. The DiagLink provides a budget-friendly option for single-brand diagnostics, while the MD806 caters to users with multiple car brands. Ultimately, the best OBDII scan tool depends on individual needs and budget. If in-depth diagnostics for a single car brand are sufficient, the DiagLink presents excellent value. However, for broader compatibility and long-term usability, the MD806 stands out as a powerful and versatile choice. Its comprehensive functionality, coupled with lifetime software updates, makes it a valuable investment for both home mechanics and professional technicians.
