11 Best OBD2 Scanners in 2021 Reviews & Buying Guide

Many people prefer to diagnose their vehicles directly at home. And it is useless to visit a mechanic store for every small issue. Besides, there are always going to be some problems on the go where you have to diagnose yourself. An ideal solution for this will be by using an OBD2 scanner.

It lets you detect issues in your vehicle by allowing you to perform an accurate diagnosis. So if you want to buy one, you should consider some important factors to ensure you are getting the best OBD2 scanner.

  • Type: There are two types of OBD2 scanners available; normal and Bluetooth ones. The normal scanners are self-sustained devices, which means they have a built-in screen, buttons, and software. On the other hand, a Bluetooth OBD2 scanner connects to a smartphone where you can check the analysis and result. Naturally, they are less costly due to the absence of inbuilt screens or controls.
  • Features: The more features and modes the scanner has, the easier will be the code reading and follow-up diagnosis. Availability of live data mode helps in reading data in graphical presentation for better interpretation. Advanced test features like smog test and misfire count are also quite useful.
  • Vehicle Compatibility: Always see if the OED2 scanner is compatible with your vehicle. Select the one that can have universal compatibility. While buying the tool, you also need to check your vehicle’s make and model.

To make sure that you have the right purchase, you can have a look at the detailed “Buying Guide” of an OBD2 scanner at the bottom of the page.

How do I know if I have OBD1 or OBD2?

If you purchased your car fairly recently, then chances are you have OBD2 in your car. To be precise, if your is manufactured after 1996 (including), then it will definitely have OBD2. Another way to identify OBD1 and OBD2 is by looking at the interface. OBD2 has a standard 16-pin connector and if the connector looks different then it is an OBD1 interface.

Is an OBD2 Scanner worth it?

It depends on the use case. If you are a mechanic or if you have an auto workshop, then OBD2 Scanner is definitely worth it.

In OBD1, the interface is specific to manufacturer. So, a scanner for one car cannot work on a car from a different manufacturer. With OBD2, the interface became a standard across all car manufacturers so you can use one scanner across multiple cars from different manufacturers. The functionalities of OBD1 Scanners are very limited such as sensors, actuators, open and shorts. OBD2 Scanner can perform complex analysis and diagnostics such as emissions, performance, smog test, battery etc.

Can I leave OBD2 plugged in?

If it is a wireless (Bluetooth) type OBD2 scanner and if you leave it plugged in, the it will drain the battery. If the OBD2 scanner comes with an ON/OFF switch, then you can leave it plugged in by turning it off.

Can I start my car with OBD2?

For normal parameters such as VIN Number, Manufacturer etc., you don’t have to start the car but simply put it in ignition. But if you want real time data from your car’s ECU, then you have to start your car.
