NO DATA

I went to forums to seek help and finally sorted it out. If you get the same error message and would like to fix it, below is the solution. It works for me perfectly.

First of all, the ELM327 code reader need to is enable in your ROM obviously first.

Then you need to the start a "startdiagnosticsession" before asking for data per specification.

Select Start Diagnostic Session and get:

Service ID 0x10
Extended Diagnostic session:0x92

And then you'll get something like:

E0 10 92

That's what I had in my code. Hope This process would work for you as it does for me.
