@dubb45, I don't see your code ... can you add it in so we can take a look?
In the meantime, I assume you are running candump / cansend on some form of unix machine. I also assume you are using a Carloop to do the USB/CANbus interface between your unix machine and the car.
Can you do some checks to ensure your unix machine and Carloop are communicating properly with each other? I would suggest having the Carloop echo back messages to the unix machine so you can check if Carloop is seeing the cansend correctly?
Give that a try and let us know how it goes!
