Vehicle Make
Compatibility
To ensure that your vehicle is covered by the manufacturer warranty, you need to pick a device that covers vehicles from every major domestic automaker. If you own a foreign or specialty vehicle, however, you might have to look for a device thatâs made specifically for that type of vehicle.
Code Reading
If the size of the display on your car diagnostic tool isn't large enough to show all the codes for each problem, consider upgrading to one with a bigger display.
Wired Vs. Bluetooth
You just need a mobile device with Bluetooth capabilities and an app for scanning barcodes.
If you're interested in an "all-in-one" solution that collects data while you're driving, then a high-end OBD2 scanner might be the right choice for you. But, if you want something that lasts longer than just one trip, then there are several models available that have internal battery packs.
Live Data Scanning
Live Scan is a powerful tool because it helps you monitor your vehicle's performance over time, as well identify any potential issues before they become an actual problem. For example, you could diagnose why your car is not performing as expected.
Data Tracking
So, you'll want to buy a device that lets you view the data in clear, easily readable graphs and charts. You'll also want one that allows you to track this data over time so you can spot trends and use them to your advantage.
Buy Based On The Work
If you're interested in scanning your own vehicles, you'll want a scanner that works with both domestic and foreign models and gets regular software upgrades. Sending commands to your vehicle via Bluetooth lets you adjust things like the climate control system and engine performance. Having access to data such as the ABS and malfunction indicators helps you pinpoint problems before they become serious issues.
Remember: More functions and programmability means a higher cost.
