A minor fault in a car such as worn spark plugs may trigger misbalanced vehicle functionality, which may in turn cause problems that can at times become fatal for the vehicle. Fortunately, modern cars have a mind of their own and can determine what each component is doing and consequentially when a component has malfunctioned. They do this through a system known as the OBD2 unit which holds a car’s full operations log, including temperature and fuel readings, speed, direction and location records, as well as testing for emission leaks and levels. If you are looking for one, below is our list of the best OBD2 scanner which you can consider buying.

Best OBD2 Scanner FAQs and Guide
Why is the OBD2 Scanner Tool Essential?
An OBD2 Scanner is a portable device that is plugged into a vehicle’s diagnostic connector – commonly known as the OBD2 unit – to test the car’s systems and identify its faults. Advanced as they may be, today’s vehicles’ sensors are often restricted to little more than illuminating a “Check Engine” light on the dashboard. Although the light indicates that something is wrong, more often than not it is impossible to discern the severity of the problem. Owning an OBD2 saves you money because you can identify the problem yourself without having to pay exorbitant ‘diagnosis’ fees to dealerships and service stations. With the acquired information, you can make an informed decision on whether or not you can tackle the problem.
What to Consider when Buying an OBD2 Scanner?
Subject to your requirements and skill level, you may opt for either a feature-packed or minimalistic OBD 2 scanning tool. While all scanners can download the standard set of data, only particular devices can show the real-time functioning of the vehicle to allow for necessary adjustments during operations. Cost is also an important factor to consider. Some OBD2 Scanners will set you back a few thousands of dollars, yet they feature limited functionalities. It is not smart to acquire an expensive ‘PRO’ scan tool if all you need is a ‘DIY’ OBD2 scanner.
The Best OBD2 Scanners on the Market and our Reviews
Recently, there has been an influx of advanced diagnostic tools from companies such as Actron (OTC), Autologic, Auterra, Bluedriver, Baum Tools, AutoXray (OTC), and Delphi among others. Consequentially, the manufacturers’ struggle to outdo each other has led to a decrease in price and a simultaneous increase in quality. However, it may be difficult to figure out which car scanner to get especially because all of them promise to deliver the best user experience. So, we ran tests and from the results compiled a list of six of the best OBD2 Scanners in the market today.
As much as factors such as cost and technology should influence your decision, it is prudent that you ensure that an OBD2 Scanner Tool is compatible not only with your vehicle but with your devices too. We recommend that you acquire a low-cost dedicated device if you only need to troubleshoot one vehicle. You should only get the more expensive, sophisticated tools if you plan on using it on multiple cars. Therefore, you should read the reviews carefully before purchasing a car diagnostic device.
After careful consideration, we believe that the BlueDriver is the most well-rounded device in the market. BAFX’s 34t5 tool is one of the most “human” devices while Actron’s CP9580A holds a reputation for being efficient and easy to use. The INNOVA 3160 and INNOVA 3100 are excellent tools and would have done better on our list if they did not charge for advanced diagnostic reports. We included the Autel MaxiScan MS300 because of its large sales volume and excellent consumer reviews which show that it must be doing something right.
Having your car break down is both inconveniencing and frustrating. With the above tools, you will be able to make timely evaluations and, if necessary, repairs before you hit the road.
