Yeah it helps a little. I scrapped some code together, and looking at the arduino side of the chip (33290) I can see that bits are getting sent but the the KLINE side of the chip is staying HIGH, I got out a voltmeter and found out that my 1998 v70 volvo has 25volts on its battery, I think this is too high? I am not able to pull the pin low it seems. I might need to get some transistors.

my code: http://code.inhocsignovinces.net/obd_terminal.pde
mostly the obduino code chopped up.

Best,
