Hi everyone,

Firstly I want to thank DCB and Magister and the rest of the developers for what promises to be a cool gadget. I built and OBDuino last weekend based on the Arduino Duemilanove for a 1999 Toyota Tacoma using the MC33290 and an ISO interface. Unfortunately I have not been able to get the Arduino to talk to the car. Much like Mothinator I get to the ISO9141 Init stage and it always fails. I have scoped the K-line and I see the initialization bytes going out the first time, but nothing else. The init does not send anything out on subsequent attempts. I cannot really tell if anything is coming back in as I can't really capture the bytes on my oscillioscope. Mothinator, did you ever find a solution? Does anyone else have ideas in things to try?
