BC message “stop brakes immediately”

Hello Fangemeinde, maybe one can help me. Have the message in the BC “brakes stop immediately” with the red light, as well as ABS/STC light. Usually after different times again. Thought that it were the brake pads, but had the day before yesterday coverings and discs changed and still this message again. OBD2 says only error P1633 (CAN data bus, ABS(speed signal) – not received in the specified time gridCable tree, CAN data bus, ABS control system Has anyone had this experience or what can it be? Greetings Frank !
