I know this happens with sonobuoys but i dont know about sub active sonar.

AI subs will do an about face if they get pinged by a Dicass. By default, with no extra work needed. Depends on tatic, i guess it works with everything except transit. They turn away them from way outside the 6nm range of a buoy. If it stops pinging they carry on with whatever they were doing before.
