How to use a car diagnostic tool like a pro

 In the digital world, cars have become more modern and its onboard electronics are becoming more diversified. Errors occur as your vehicle ages due to time and use, which can affect functionality of your car. For example, if your engine light is on maybe it will leave you stranded in the middle of the road. Airbags may not function well. In severe situations, serious accidents may occur due to faults in the vehicle, which lead to damages to your car, shorten the life of your car and cost you a lot of money. All these can start from a minor issue without you noticing.



What’s a car diagnostic tool?

A car diagnostic tool, also known as an OBD scanner, is a car scanner that scans and examines your vehicle to prevent any major issues before your vehicle gets into trouble. It’s a must-have that can quickly help troubleshoot issues in your vehicle. The term“OBD” stands for On-Board Diagnostics. The tool is connected to the car via the OBDII port underneath the steering wheel and an OBD cable that usually comes with a tablet for a smooth user experience.

By accessing the data memory of the control units, the car diagnostic tool can diagnose on-board electronics and identify where your car troubles lie and analyze them.

After evaluating and analyzing data from the vehicle’s electronics, the car diagnostic tool can generate error codes and provide detailed explanations that are stored in the tool.



Why do you need a car scanning tool?

The importance of performing regular diagnostic tests for your vehicle cannot be understated. With a professional car diagnostic tool, you’ll be able to estimate if you have a serious issue that you need to get help from a professional technician for, or if it’s a simple matter that you can fix yourself.

For example, if you’re a car owner that truly pays attention to the health status and life of your vehicle, having one of these OBD scanners at home or in your vehicle is incredibly convenient when you need one to check potential mechanical problems.

Let’s take the check engine light as an example. If the light is on when you’re driving on the road, you can use the car diagnostic tool that you have on hand to help you run a quick diagnosis by plugging it into the OBDII port. It eases your mind and saves you money and energy.


How Often Are Car Diagnostic Tests Needed?

It’s common for most people to go to a mechanic or auto repair shop when their vehicles get the“Check Engine Light” warning or encounter malfunction issues. It’s recommended that you regularly test your cars to prevent any serious issues that may develop over time.
