Hi,

What do you mean "when I disconnect CAN H or CAN L line"? do you means that you disconnect both the CAN H or CAN L line between transmitter and receiver nodes?

Educate yourself about the meaning of transmit / receive errors, error passive state, and bus-off state, which are intrinsic part of the CAN specification.
