I was setting up a room for defenses, and had the diagnosticator in the back corner area. Any turret that wasn't blocked in a straight line to the diagnosticator was healed slowly as per the turret's description. I can smack it to heal all the turrets in the room, but it does not heal autonomously to turrets in the same room that are blocked from it's "sight".
