How to find a good OBD2 scanner for diagnosing your car for problems

OBD2 is an onboard diagnostic system that is found on every car moving on the road today. This device not only provides control to the engine, but also monitors the performance of the chassis, electronics, accessories and other control parts of the vehicle.  OBD2 is able to monitor the performance of a vehicle by the minute and then display the problems in codes. These codes have a corresponding meaning and you will need an OBD2 scanner to decode the meanings of these codes. Proper interpretation of the codes will enable you to make the right diagnosis and therefore, be able to solve the problems that your car is having. However, you need to buy the scanner yourself as it does not come with the car.

Choose an OBD2 scanner that is not OEM specific

As you go shopping for an OBD2 scanner, you need to ensure that they are not OEM specific as this will limit you to that specific type of a car.  Therefore, the OBD2 scanner that you choose should be able to read codes on multiple types of vehicles. This will save you a lot of money for you will not have to change the scanner when you change your vehicle.  

Functions of the scanner

As you shop for an OBD2 scanner, it is advisable to go for a product that comes with multiple functions. There are OBD2 brands in the market that just read a code without providing more details. Therefore, it is important to go for products that give you a better description of the problem that your car is having. This is to make it easy for you to understand the problem. As obd2pros said here, it is important to note that such OBD2 devices are sold at much higher prices when compared to the competition.  

Ease of use

Ease of use is another factor that you should consider when buying an OBD2 scanner. The right scanner should have simple controls that any one can understand. Unfortunately, there are some OBD2 scanners in the market that are very hard to use because of their complicated operating systems and user interface. Therefore, a good OBD2 scanner should be simple and straight forward to use even for beginners on car repair.  


Price is the next factor to look at when buying an OBD2 scanner. You will find that different OBD2 scanner devices come at varying prices depending on their quality and functions. You will find that the prices for these devices range from $50 to $350 in the market. Therefore, it is important to put a balance between the features that you are looking and your budget so as to get a scanner that meets your car diagnostic needs


As you shop for an OBD2 scanner, it is also important to quality. The best scanner in the market should come with a great quality and design so as to last for a long time. Since these devices are prone to falling and scratching, they should have a high quality casing.
