doubts regarding CAN protocol

[ep.hobbyiest]

hi,
i got some doubts while reading CAN protocol.

Every CAN controller along a bus will try to detect errors within a message. If an error is found, the discovering node will transmit an Error Flag, thus destroying the bus traffic.

in this which error flag will send by node who detect the error.(active/passive/any other)

In next case also

Let’s assume that node A on a bus has a bad day. Whenever A tries to transmit a message, it fails (for whatever reason). Each time this happens, it increases its Transmit Error Counter by 8 and transmits an Active Error Flag.

in this case if other node detect the error then also transmitter will send error flag? or node who detect error will only send error flag?
