If you can help with it? This is should be the rx tx arduino to k-line on obd2. K-line works on -12 +12. I just wanna see if I'm not gonna bern arduino and how the signals apply.

Bro, can you be more specific? I didn't understand the circuit. Sorry

Your topology is choppy, it's fixable, but it'll take some work. They do sell an attachment for the raspberrypie controllers that connect directly to the CAN_H and CAN_L pins on the port, best part with the raspberrypie is it's a computer so you can do any programming/diagnostics with it on the ODB or even straight into the ECM as I have before

I don't know what to put in circuit as comments.. on the left side here is 2 lines that shold be Rx and Tx on the right side it is one line (K-line) The conversation goes by one line in both ways and sprayed in 2 lines Rx,Tx.... Rx. Tx they are max 5 volts. The K-line works in range -12 to +12v.... Is here anything in this app that can imitate the data flow throw the circuit I can put instead of current sourses???
