Looking for a good reliable code reader.

Whats the difference from the OTR Diagnostic and the Reset?

 

I believe the reset only does code clearing and regen. The diagnostic will give real-time reading and history type features. Their website explains it very well along with phone help. I called and discussed this with their tech help and decided on the diagnostic. I have done one forced regen and haven’t used it since. The once your ready for a problem, you don’t have a problem principle in action
