Arduino using can bus

Hey, i am trying to use arduino mcp2515 to transfer info to the roborio. Mcp2515 is a can bus connector for arduino. I tried to connect it to the can bus chain but everytime i am trying to send a messege through the arduino its making the chain to break. Someone have an idea whats making this happen? And how to recognize it in the computer(cause the Phoenix tuner dont recognize it)
