The invention relates to a trailer control module and a trailer control valve arrangement. A trailer control module (1) for an electropneumatic brake system (100) comprises a trailer control valve arrangement (TCV) (20) connected at least to a supply connection (2) for receiving a supply pressure (pS) and providing a trailer control pressure (pTC) to a trailer working port (6), the TCV (20) comprising a shut-off valve unit (26), and a relay valve unit (30) for switching between a supply state enabling fluid communication between the supply connection (2) and the relay valve unit (30) and a disconnected state for throttling said fluid communication. The cut-off valve unit (26) comprises a switching member (54) which is subjected to a first pressing force F1 defined by the pilot control pressure (pPC) and a counteracted second pressing force F2 defined by the trailer control pressure (pTC), where the switching member (54) switches to the cut-off state in the event that the second pressing force F2 falls below a
