I soldered all the connections, put Uno on my clone and started reading messages on the machine with no problems. I preferred the SparkFun examples (CAN_Read_Demo and CAN_Write_Demo) to the vendor ones. Luckily I set Serial.Begin to 500000 baud and made sure my serial monitor matched. Looking between the two, I'm not sure why I preferred the SparkFun library. They seem very similar, except that SF doesn't put a space between the header length and the first data byte, which confused me at first. Anyway no problem and I was able to read and write codes on HS-CAN on my car.
