Compatibility Problems: OBD2 Protocol and Vehicle

While most cars from 1996 onwards support OBD2, some earlier models or specific vehicle makes might use a different protocol.

Try using the scan tool with a different vehicle or using a different OBD2 adapter with your current car to isolate the issue. If the scanner works with another vehicle, the problem likely lies with your car’s OBD2 port. If it doesn’t connect to any vehicle, the scanner might be defective.
