The charts shows how to go about checking the problem. Most probably you have a bad light switch.

I have the simular problem headlights work until I turn the key in the ignition. Then the headlights go out I've replaced the headlight switch, ignition switch, relay. Still can't find the solution.

A TSB was issued for faulty malfuntion switch which could be the cause. Contact the nearest dealer for more information.
