If you own a car, you may have heard of an OBD reader. OBD stands for "On-Board Diagnostic" and is a tool that helps diagnose problems with your car's engine by interpreting the error codes stored in the on-board computer. In this article, we'll explain how to use an OBD reader to find problems with your car and save money by carrying out repairs yourself.
What is an OBD / OBD2 diagnostic reader?
An OBDII reader is a tool that allows you to solve your vehicle's engine problems by deciphering the error DTCs accumulated in the on-board computer. It comes in the form of a scanner, cable or box that connects to your car's OBD interface. The OBD2 interface on your car or motorbike is a connector that is generally located under the dashboard of your car.
OBDII readers come in a variety of shapes and sizes, but the most popular are Bluetooth OBD2 readers, which connect wirelessly to your smartphone or laptop via Bluetooth or Wi-Fi. There are also OBD2 readers that connect via a USB cable.
How do I use a Bluetooth / WIFI OBD2 reader?
To use an OBD-II reader, follow these steps:
- Connect the OBD-2 reader to your car's OBDII interface: most cars manufactured after 1996 are equipped with an OBD2 interface, but it's important to check your car's owner's manual to determine the type of connector you need.
- Install the compatible application on your smartphone or computer: to use a Bluetooth OBD reader, you need to download a diagnostic application that is compatible with your device. The most popular applications are Torque Pro for Android and Car Scanner for iOS.
