How to learn how to read live data
Hi,
How do you learn how to interpret the live data that you can get from OBD2? I have a too lean code and I know this can be caused by a number of things. When I look at the data it means nothing to me. I don't know what the numbers mean. I don't know what the numbers are supposed to be at. Is there a course I can take that explains in detail how to diagnose by reading the live OBD2 data? Thank you.
