Understanding the potential causes can help you pinpoint the problem more effectively. Sometimes, the issue isn’t the OBD2 port itself, but a related component. This is why it’s important to systematically check all possibilities.
Why is my OBD2 port not working?
A non-functioning OBD2 port could stem from a blown fuse, a wiring issue, or even a problem with the cigarette lighter fuse, which is often connected to the OBD2 port’s power circuit.
