Have you tried to click on the test in settings interface? if the error message there is a problem in the elm327.Some china sellers have bad interfaces with elm327 1.2 :).
ELM327 v 1.4

thanks for response.....however I tried the test but the result is always this error ATBI 94.... :( :( :(
I read in this forum that some people have solved the problem removing a resistor (R4 or R25/26) from the interface and add another 120 ohm and 560 pf between 6 and 14 pin ;)
Is possible on my type of interface or I have to buy another ??? :(

Hi
If you try to connect to a can ecu or to the body,
maybe you have a foulty interface...

you have to change c14 and c15 capacitors that are wrong value.. change with 2 new one of 560pf value..

Sembra andar bene..
I condensatori sono nuovi sono giusti?? Li hai provati con un tester che provi la capacità??

It's look like ok.. but le capacity of the 2 capacitor are ok?? Do you have tested??
