bus - LIN bus slave transmitting without master

Question

How does a LIN bus slave device behave, if no master is connected?

In my research I noticed, that in LIN version 2.0 every message is initialized by a header frame which is sent by the master device. For tests I powered a LIN slave device and did not connect any master to the bus. Then I measured the voltage on the LIN bus line with an oscilloscope. And I seems that the slave device is transmitting data.

How can this be explained?
