Baud rate mismatch on CAN network

We are using the onboard MSCAN module in a MC9S12DP512 and have a question about CAN baud rate mismatches on a CAN network. As an example, assume we have a CAN network in an automotive setting (OBD bus) that is running at a baud rate of 500k. What would happen if we connect a CAN device to the CAN network (OBD bus) that is operating at a baud rate of 250k but is not making any OBD requests - just listening only? Would one of the nodes on the network start generating error frames?

 

Thanks,
