When the car is turned off the lights should go back to their "home" position. If they are not then it's either the motors or an electrical problem effecting AFS.
Dig through the FSM and see if you can find a wiring schematic and also a troubleshooting section for AFS. I'm about to head out for the next day or two and don't have the time to dig into it myself.
