Hi all,
I´m totaly in dead end, don´t know where is the problem...
I´m trying to use this http://www.instructables.com/id/Hack-an-ELM327-Cable-to-make-an-Arduino-OBD2-Scann/
But in RealTerm i see only some cluster of characters (in attachments)
Using TX, RX, GND soldered on chip (CH340T) in OBD adapter.
Adapter work like a charm, when I use OBD Doctor there is no problem.

That instructable uses an LCD to display the data. As you have a screen shot of a serial terminal you're using something different. Post a wiring diagram of your hardware and post the code you're using (use code tags!).
Yep i know that. But i just looking how Uno communicate with OBD.
Because no data on LCD. Still connecting.
ELM TX -> UNO TX
ELM RX -> UNO RX
ELM GND -> UNO GND
*ELM = CH340T
ELM TX -> UNO TX
ELM RX -> UNO RX
ELM GND -> UNO GND
That means you have no sketch loaded on the UNO?
BTW, the ELM communicates with 38400 baud but your terminal program was set to 57600.
I use same sketch like that guy on instructables.
Yep i got it now, i will try some thing tomorrow.
THX
