I didn't checked this example, but if you write more about the 
error, we can help you to solve it.

Note, that you must have more than one CAN devices at the CAN 
bus. In other case you don't get an ack for your transmission 
and your CAN Controller go in the state Error passive.

What do you mean with high state? 
Could it be, that CAN-H and CAN-L have the same voltage (~2.5V).
Than the difference voltage is 0 and it's the recessive state an 
your hardware is OK.
