What difference does a USB cable make?
With an OBD2 port in the car, you can retrieve information from the control unit. But you still need to connect to it and read its data.
There are several ways to establish the connection between the OBD2 device and the diagnostic software. One of them is the wired connection, also known as the USB connection.
Which devices are compatible?
Obviously, to connect anything with a USB cable, you need a USB port. This is why OBD2 USB tools are only compatible with PCs or MacBooks.
If you want to use a recent MacBook (after 2016), make sure you have a USB adapter.
How to ensure the connection between the device and the software?
To perform your car's diagnostic, you need to connect the device to the diagnostic software. To ensure all information is transmitted correctly via the wired connection, follow these steps.
