FAQs

Is it worth buying an OBD2 Scanner?

It depends, in some countries like the USA, major auto repair chains will offer you an OBD2 scanner to check for yourself. But if you are someone who wants to check daily, then you may invest in one. Since OBD2 scanners are just a few dollars on AliExpress, I recommend you to invest in one from the above list of best AliExpress OBD2 scanners. 

What is the difference between OBD1 and OBD2?

The OBD1 needs to be connected to the console of your car while OBD2 can be remotely connected to your car. OBD1 was used in cars before 1996, while OBD2 has been the standard since then. 

What cars are compatible with OBD2?

OBD2 compatibility depends on the car model, but since 1996, most American cars have had OBD2 compatibility. Similarly, 2001 and later for European Union cars and 2002 for Asian cars. So, there’s a high chance that cars since 2005 support OBD2 compatibility.
