No
It is not possible to read SID201 with KESS on obd, you can only ID and write
If you have correct virtual read file you can write and will work perfect
In my case I writed the wrong virtual read file and ecu locked, had to read on BDM, rebuild file and write again
Be careful because if you write wrong file car will not start and you will not have true read from ecu

Ahh damn it! I bought KESSv2 as first reply thought it would do it.
Is there any tool that will read via OBD? Or should I buy KTAG instead then? Or, How do I find correct virtual read file?

Many thanks for your input and info by the way
