Top 5 Best OBD2 Scanner in 2017 from


OBD or on-board diagnostics scanners give access to the different sub system statuses. They actually give a diagnostic review of the defects of the cars and their over-all health. This computer-based system was originally designed to reduce the emissions of the cars by monitoring the performance of major components of the engine of the car.

If the car has broken down in the middle of nowhere then an OBD helps to identify and analyze the cause of the fault. Early versions of this system only consisted of a light that would get illuminated when there was a malfunction. The second generation on board diagnostic scanner tool or OBD2 Scanner consists of an electronically controlled fuel ignition that analyzes engine performance through sensors and helps to control emission. All the cars that are compliant with the new OBD2 are usually fuel efficient, which will thereby help to keep the air clean. The malfunction indicator light (MIL) points out any problem of the car engine in a jiffy. Also, the OBD2 has reduced the occurrence of road accidents caused by minor defects in the car; the car cannot just break down in an isolated place without the driver knowing what should be done.

The MIL comes on whenever there is a problem with the engine. It does not always concern drivability but may indicate other trivial problems as well. But most often it is because a major issue has arisen and so one should never ignore the MIL when it is illuminated.

Like everything else in the world, OBD2 scanners, too, are of various kinds and one should always consider the pros and cons of each and every one of them before taking a final decision. All products do not give the same performance or show the same kind of functionalities – it is very important to choose the OBD that is suitable for one’s car; different OBD’s are good for different vehicles. The following should be considered while buying suitable OBD2 tools:

  • Price: Although all of them have the same OBD2 technologies yet the prices vary: it depends on those extra features some of them provide. Due to the presence of some advanced features, some OBD2 equipments have a higher price. The price of OBD2 scanners mostly range from 250$-2500$.
  • Compatibility of the vehicle: The OBD2 technology supports three kinds of hardware communication. Those OBD2 tools which support all three are called universal scanners and there are some which support only a specific one. Also, depending on the country the user lives in, it matters which OBD scanner he is using: some support OBD1 after a certain year and some OBD2.
  • Functions: Apart from the basic function that all OBD2 scanners are supposed to perform, some of them offer extra amenities and services. Not everyone needs every one of them: it just has to be kept in mind which all are required otherwise it might lead to wastage of money.
  • Manufacturer: Not all manufacturers produce every kind of OBD2 tool: some of them are better at making the advanced ones while others excel at producing the basic tools. Depending on what one might need, he should choose the manufacturer.
  • Material of OBD2 tool: These tools come in different cases: some material which might be handy for person X might not be so for person Y.
