There are many different types of OBD2 code readers on the market today. Some scanners use the universal connector, but some use the OBDII connection. Some of these devices actually hook up to your vehicle’s computer system and upload the codes from the scanner into your computer. For most people, the convenience of the portable OBD2 system outweighs the differences between the various scanners.
The best way to choose an OBD2 code reader is to make sure that it is from a well known and trusted manufacturer. Once you find one you like, you can test drive it to see how it works.
