Finding the best OBD scan tool to buy can be challenging with so many options available. This guide will help you understand the different types of OBD scanners and what features to look for when making a purchase, focusing on tools that can access more than just basic OBDII data.
Beyond Basic OBDII: Accessing Full Vehicle Systems
A simple Bluetooth OBDII dongle and a phone app, while affordable (around $13), often lack the capability to read beyond standard OBDII systems. For instance, checking oil level requires access to non-OBDII systems, as oil level isn’t part of standard OBDII data. While OBDII codes can indicate a faulty oil level sensor, they won’t provide the actual oil level. Tools like the VeePeak scanners are explicitly designed for OBDII scanning only. To access a broader range of vehicle data, including oil level, you need a scan tool capable of communicating with the car’s non-OBDII systems, similar to how professional-grade tools like the VIDA/DiCE combination function.
Affordable Single-Brand Options: The Autel DiagLink
For around $90-$100, the Autel DiagLink offers a budget-friendly entry point into accessing non-OBDII data. However, it’s crucial to understand its limitations. The DiagLink works with only ONE car brand. You receive free brand-specific software (downloaded and installed from Autel) for a single manufacturer. Accessing advanced non-OBDII functions on another car brand requires purchasing additional software from Autel (approximately $10 per brand).
Despite this limitation, the DiagLink provides excellent value for its price for users who own a single car brand and plan to keep it long-term. It offers functionalities like resetting oil change lights and controlling electric parking brakes, features typically unavailable in similarly priced scanners.
Multi-Brand Versatility: The Autel MD806
If you need a scan tool that can handle multiple car brands, the Autel MD806, priced around $200, is a solid choice. While potentially using similar hardware to the DiagLink, the MD806’s software supports multiple brands without requiring separate downloads for each. It also includes “lifetime” free software updates, meaning updates are provided for the expected lifespan of the tool. While updates might not be available indefinitely (e.g., after 15 years), the MD806 offers a compelling combination of features and long-term value.
This scanner caters to the needs of most home mechanics, providing comprehensive functionality without a hefty price tag, especially for frequent users. It allows access to data beyond basic OBDII codes, enabling tasks like oil change resets and parking brake service mode activation.
Conclusion: Choosing the Best OBD Scan Tool
Choosing the best OBD scan tool depends on your individual needs and budget. For single-brand use and basic non-OBDII functions, the Autel DiagLink offers an affordable solution. For multi-brand versatility and long-term value with free software updates, the Autel MD806 is a strong contender. When considering your purchase, remember that accessing information beyond basic OBDII diagnostics requires a more advanced scan tool than a simple code reader. Consider your long-term needs and the types of vehicles you work with to make the best decision.
