2. The speed threshold in MD 1360: $MD_SAFE_STANDSTILL_VELO_TOL of STOP B has not been reached.
3. The test of the deactivation path has been requested by the user through SGE “Test stop selection”, but the pulses were not deleted in MD 1357: $MD_SAFE_PULSE_DIS_CHECK_TIME when the time stage expired.
4. Safe brake ramp has responded.
