How to verify CAN-BUS MCP2551 MCP2515 Module operation before install

Need guidance on how to test the CAN BUS module I have, before wiring it into my car. It is connected to a Udoo Bolt SBC that has an embedded Leonardo board on it. I have the module connected to the correct Udoo Grove port, with a seeed cable. It isn’t connected to CAN network yet. It does power up. Loaded the CAN sketch from the library, and would like to verify it’s working.
