If a Bluetooth OBD2 scanner seems like a better fit for you, we’ve reviewed and tested a handful of the top products on the market. How Much Does An OBD2 Scanner Cost?

The Foxwell NT201 is lightweight but does not feel especially durable. It doesn’t seem like this tool would survive many drops onto a hard floor.

The Launch has an easy-to-use touchscreen interface and a long connection cable. Some OBD2 scanners have shorter cables that make it difficult to hold the device in your lap once connected. You’ll need a specialized scanner if you want to perform more advanced tasks, like reprogramming your engine control module. Sending commands or changing vehicle settings is helpful if you’re working with temperature sensors or tire pressure monitors. Access to readings such as the ABS and misfire information can help better diagnose a car’s overall health. Some other scan tools have a bigger screen and it’s a bit easier to read. Not a huge issue, though. OBD diagnostics tools have been around for some time now, and they’ve been a godsend every single time. Its ability to pinpoint fault codes, analyse the condition and operational functionality of a car, or simply reset and turn off warning lights, is a blessing. While any OBD scanner and reader is far better than nothing, some are a league above the rest. This is TOPDON’s goal – make the best out there. All you need is a smartphone with Bluetooth capability and the scanner’s corresponding app (which may not be free), and you can review data directly from your phone.

Smog test : A smog test measures your engine’s emissions and determines if your emissions systems are working properly. All vehicles in the United States must meet certain emissions standards. You cannot pass inspections by running tests at home, but you can determine beforehand if your vehicle will pass an emissions test. Many of these OBD2 scanners’ advanced features are really only useful to home mechanics who feel comfortable working on their own vehicles and are not intended for average drivers. Just remember that more features and programming options mean a higher price tag. How To Use An OBD2 Scanner All of the OBD2 scanners that we recommend are compatible with a broad range of vehicles. However, not every OBD2 scanner works perfectly with every vehicle. Each manufacturer (especially in different countries) uses its own computer protocol for storing vehicle fault codes. OBD2 scanners that support the broadest range of protocols score best in this category. For non-mechanics, the most useful OBD2 scanner features are reading error codes and the smog test. More advanced features are only useful when paired with at least some mechanic know-how. OBD2 Features: What Experts Are SayingIt works with a lot of vehicles, so as well as working with your current vehicle, it’s likely to work with the next one too.

Real-time data: Accessing real-time data is not necessary for most people. For those with advanced automotive know-how, this information can help optimize engine performance and diagnose certain repairs. In addition to engine information like temperature, RPMs, and fuel injection rate, you can also monitor ABS and battery data. Steering Angle Sensor (SAS) calibration : All modern vehicles are equipped with power steering systems that greatly assist in handling. If the SAS is improperly calibrated, your vehicle will be difficult to steer and may handle strangely (the wheel turning too easily, or only with difficulty). The SAS typically needs to be reset after any wheel alignment.C : Indicates an issue with the chassis (components underneath the car such as the axles, ABS, wheels, and power steering) Each year, we test over 350 auto products on vehicles and in our testing lab. Our team of product testers thoroughly researches top products, unboxes and puts our hands on each component, and tests the items on real vehicles before making recommendations to readers. When in use for an extended period of time, the display unit can get warm. Just a little, nothing to be concerned about. What Maintenance Services does it cover?
