Before shopping for the Obd2 scanner tool, there are several things you need to think about.

If you're looking for the Obd2 scanner tool, don't worry! We've created a buyer's guide to help you choose the right one for your needs.

We looked at dozens of keyword tools to help us understand which keywords were most profitable. For further details, read our article.

Wired Vs. Bluetooth

If you want an OBDII scanner, consider Bluetooth compatibility. Because most OBDII scanners come with cables, they keep you closer to the car than if you were using a wireless device.

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.

Data Tracking

A modern scanner can give you a lot of useful information about your car. But unless you know how to read and interpret it, it might be hard for you to understand what it all really means.

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

To figure out which OBD2 scan tool you need, consider what kind of work you’d be doing. If you’d just be checking for codes, you might want something that can read them.

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.

Code Reading

We mentioned earlier that the primary function of an OBD2 scan tool is to read and display vehicle trouble codes (or "check points"). Some scanners will just show you the single most recent check point, but others will provide additional information about the problem.

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.


All car manufacturers create code systems for each of their cars. While the OBD2 (on board diagnostics) systems are standardized, the codes are unique to each vehicle.

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 that’s made specifically for that type of vehicle.

Live Data Scanning

Today, most cars have onboard computer systems that let you monitor all of your vehicle's systems at once.

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.

Vehicle Make

While many OBDII code sets are universal, a good portion are not. In addition to common code sets, every car also has a brand-specific fault code set. The best OBDII readers can read these code sets from most major manufacturers. If you intend to use your OBDII reader with a specific automobile or group of automobiles, make sure it is able to read any relevant error code sets for that particular brand.

Repair Manuals

If you use an OBD2 scanner to determine whether there are any issues with your car, don't assume you know what to do if something goes wrong.

You can use these repair guides and online communities to learn how to diagnose and fix your vehicle without having to pay for expensive repairs.

If you're a hands-on car owner, having access to these guides will be invaluable, and it could save you tons of money by avoiding the mechanics for minor repairs.


We hope the shopping advice above will help you locate the right products for your requirements. When buying, remember to check out quality brands like Bluedriver, Zmoon, Obdeleven, Topdon, Foxwell.


1. What Vehicle Problems Can An OBDII Scanner Detect?

An OBDII scan tool allows you to read your car’s computerized diagnostic trouble codes. You can also learn how to change them yourself if you know what you're doing.

2. Why Would I Want An OBDII Scanner? After All, I Can’t Fix My Car Myself.

Having an OBD II scanner at your house is useful even for people who haven’t any knowledge as a auto technician. By running the scanner you can discover code numbers that provide you with an understanding of what’s incorrect with the automobile. You can also learn whether the automotive service provider is being fair in regards to the offered services. Furthermore, you will know whether the garage is dealing with you fairly concerning suggested fixes.
