Reading your car’s diagnostic codes used to require a trip to the mechanic, but today’s car scan tools empower home mechanics to diagnose and fix issues themselves. If you’re searching for the best car scan tool in 2017, this guide will break down top options for accessing both basic OBDII and advanced non-OBDII systems.
Beyond Basic OBDII: Why You Might Need More Than an ELM327
While a simple Bluetooth ELM327 dongle paired with a smartphone app might suffice for checking engine codes, these setups are limited to OBDII data. Tasks like reading oil levels or accessing manufacturer-specific systems require a more advanced scan tool. ELM327 dongles won’t provide oil level readings (though they can detect faulty oil level sensors) because oil level isn’t part of the standard OBDII data set. Similarly, tools like the VeePeak scanners explicitly state their limitation to OBDII scanning.
Affordable Single-Brand Solution: Autel DiagLink
For around $90-$100, the Autel DiagLink offers a cost-effective entry point into non-OBDII scanning. This tool allows access to advanced functions like resetting oil change lights and controlling electric parking brakes. However, the DiagLink’s functionality is limited to a single car brand. Upon purchase, you select one manufacturer’s software to install on the device. While additional brand software is available for around $10 each, this limitation makes the DiagLink best suited for owners who plan to stick with one car brand long-term.
Multi-Brand Versatility: Autel MD806
If you need a scan tool capable of handling multiple car brands, the Autel MD806, priced around $200, presents a compelling option. While potentially using similar hardware to the DiagLink, the MD806 comes equipped with software supporting multiple manufacturers without needing separate downloads. It also boasts “lifetime” free software updates, although this typically refers to the expected support lifespan of the tool rather than indefinite updates. The MD806 strikes a balance between capability and cost, offering a wide range of functions suitable for most home mechanics.
Choosing the Best Scan Tool for Your Needs
Ultimately, the best car scan tool for you depends on your specific requirements. If you need advanced functionality beyond basic OBDII diagnostics and work with a single car brand, the Autel DiagLink offers an affordable solution. For multi-brand compatibility and long-term value, the Autel MD806 stands out as a top contender in the 2017 market. Consider your budget, the types of vehicles you work on, and the features you need to make an informed decision.
