Tips on how to optimize your car with an OBD scanner


The introduction of the OBD system dates back to the sixties where the main reason for its introduction was for the measurements of the vehicle’s emissions. Decades later, there was development of a more robust version called OBD-II which was also able to monitor parts of the chassis and the body. Under the car’s dashboard, there exists a little port which is part of the on-board diagnostic system. This port plays a major role in minimizing pollution that is caused by cars. As a matter of fact, devices that have been plugged into the port provide insights and optimize the driving experience. In order to ensure that there always exists a smooth fault repair process, it is important to learn how to use the scan tool. This knowledge on the correct use of the scan tool prevents scanning mishaps or misinterpretation of the troubles code which may have been coded. Below are some tips on how to optimize your car with an OBD scanner.

Checking the compliance of the car

This is a very important step aimed at ensuring that the car user manual complies with the requirements of the OBD regulations. It is worth remembering that this scan tool was basically formed so as to control the rate of emission in the environment therefore if it is well used, then its efficiency increases. The OBD is a computer controlled interface working with several sensors so as to provide an indication of the state of the car engine health. It is important to know the coding capacity as this enables the user make a good selection on the relevant scan tool for the given car.

Plugging in the OBD scan tool

When you detect an engine fault, then you have to make the connection of the scan tool. In most vehicles, the connector is located below the driver’s seat. After establishing a connection, the engine should remain awake. Plug in allows the scan tool to display certain basic information regarding the car. The OBD display provides options to the driver to scroll down and choose whether he wants to check trouble codes.

Getting the code readings

After the selection of the relevant keys, the scan tool shows the codes and their meanings. The coded data reading is displayed on the screen of the OBD ii scanner for the user to see. The use of new generation scanners displays data on the screen of the desktop or the laptop, and this is usually one area where the scan completion process can be well known.

Providing solution to the trouble codes

It is important to check on any possible fault code sources through the data code readings on the screen. It is also imperative to consult a qualified mechanic to see if the problem could be arising from other areas. This is because the mechanic may know how to translate the codes of the tool is not fitted with the necessary code translation guides.


The OBD scan tools have different shapes, and they also differ of data for which they can code. The use of new generation diagnostic scanner may prove to be a convenient affair. The main reason behind this is that though older readers are usable, it is notable that the amount of data they cover is exceeded by the new generation scan tools.
