I’m looking to buy my own diagnostic code reader for my 2017 Hyundai Tucson. I’m a bit confused about what type to get, as I’ve heard there’s a difference between OBD and OBD2. I’m new to this terminology, so any help or recommendations would be greatly appreciated! 
When it comes to diagnostic code readers for your 2017 Hyundai Tucson, you’ll want to get an OBD2 reader.
This is the standard for most modern vehicles, including your Tucson. OBD2 readers can help you diagnose issues and potentially save you money on repairs.
Look for a reputable brand and ensure the reader is compatible with your specific vehicle model and year.
